When summer rolls into London, it’s no secret that homes across the city can quickly become uncomfortably warm — especially modern flats and well-insulated houses. That’s when air conditioning stops feeling like a luxury and starts feeling like a necessity. But with so many options on the market — from split systems to ducted setups, portable units to multi-room solutions — it’s easy to feel overwhelmed. The good news? Choosing the right air conditioning system for your home doesn’t have to be complicated. In this guide, we’ll walk you through everything you need to know: from understanding the types of systems available to identifying which option best suits your home, lifestyle, and budget. 1. Understanding the Main Types of Air Conditioning Systems Before you start comparing brands or prices, it’s important to understand the key types of air conditioning systems available in London homes. Each has its own strengths, depending on your layout and comfort goals. Split System Air Conditioning This is the most common choice for London homeowners. It consists of one indoor unit (mounted on the wall) and one outdoor unit. It’s ideal for cooling single rooms such as bedrooms, lounges, or home offices. Affordable and energy-efficient Quick to install Quiet operation Perfect for smaller homes or flats where you only need cooling in one or two areas. Multi-Split System Air Conditioning A multi-split system connects several indoor units to a single outdoor unit. Each room can be controlled independently, giving you complete flexibility. Great for medium to large homes Sleek, minimal outdoor footprint Individual room temperature control This option suits London homes that want tailored comfort in multiple rooms without cluttering the exterior. Ducted Air Conditioning For those wanting a seamless, whole-home cooling solution, ducted systems are unbeatable. They use concealed ducts to deliver conditioned air throughout the property, controlled via a central thermostat or smart home system. Even temperature distribution Hidden design with minimal noise Adds long-term property value Ducted systems are ideal for full renovations, new builds, or high-end homes where design and comfort go hand in hand. 2. Match the System to Your Home and Lifestyle Choosing the right system is about you — your space, your habits, and your comfort priorities. Ask yourself: How many rooms do I need to cool? Do I want individual temperature control? Is aesthetics important? What’s my budget for installation and running costs? For instance: A compact flat in North London might only need a single split system in the living space. A detached house in West London could benefit from a ducted system for whole-home comfort. A home office setup could use a portable or wall-mounted system for flexibility and quick installation. 3. Energy Efficiency — Save Energy, Save Money With London’s growing focus on sustainability, energy-efficient air conditioning is a smart investment. Look out for these features when choosing your system: Energy ratings: Aim for A++ or A+++ efficiency. These systems consume less power and are environmentally friendly. Inverter technology: Instead of turning on and off constantly, inverter-driven systems adjust power output to maintain consistent temperatures — saving electricity and reducing wear and tear. Eco-friendly refrigerants: Modern units use R32 refrigerant, which has a lower environmental impact compared to older gases. Pro Tip: Over the lifespan of your system, energy-efficient models can save hundreds of pounds in electricity costs — especially in homes using air conditioning year-round for both heating and cooling. 4. Don’t Overlook Noise Levels and Design London is a bustling city — so your home should be a calm retreat. When choosing your air conditioner, pay attention to noise ratings. Indoor units can be as quiet as 19–25 dB — that’s softer than a whisper. Outdoor units can be strategically placed or shielded to avoid disturbing neighbours. Design options now include ultra-slim and minimalist wall units that blend into modern interiors. If you live in a listed building or apartment complex, check any restrictions before installation — an experienced installer like INS Air Conditioning can help with the necessary permissions and placement advice. 5. Budgeting: What Does Air Conditioning Cost in London? Air conditioning installation in London varies depending on your system type, property layout, and number of rooms. Here’s a general guide: Single split system: £1,500–£2,000 (installed) Multi-split system: £2,500–£4,500 Ducted system: £5,000+ (depending on size and complexity) Remember to factor in: Running costs (based on energy rating and usage) Annual servicing (to maintain efficiency and warranty) Manufacturer warranty (most offer 3–5 years with regular maintenance) An experienced installer will assess your home and provide a tailored quote — ensuring you get the right system without overspending. 6. Installation and Aftercare Even the best system won’t perform properly if it’s not installed by a qualified engineer. Incorrect installation can lead to inefficiency, higher energy bills, and even premature breakdowns. At INS Air Conditioning , our F-Gas certified engineers ensure every system is installed safely, efficiently, and in line with the latest UK regulations. We handle: Electrical setup Refrigerant management Airflow testing and system balancing Once installed, regular maintenance is essential. We recommend scheduling a service twice a year — once before summer, and once before winter — to keep your unit clean, efficient, and performing like new. 7. Smart Features to Consider Modern air conditioning systems can integrate with your smart home setup, allowing you to control temperature, schedule cooling times, and monitor energy use right from your phone. Look for: Wi-Fi connectivity Smart thermostats Voice control compatibility (Alexa, Google Home) These features add convenience while helping you manage energy use more effectively — ideal for tech-savvy London homeowners. 8.

Running a business in London comes with enough challenges — from managing staff and customers to keeping costs under control. But one area many businesses overlook is their air conditioning system . Your AC does more than keep the air cool; it maintains comfort for employees, protects valuable equipment, and can even impact productivity. Yet, without regular maintenance, it can also become one of your biggest hidden expenses. In this article, we’ll explain how regular air conditioning maintenance in London can save your business money all year round — and why a simple service plan could be one of your smartest investments. 1. Prevent Costly Breakdowns There’s nothing worse than a broken air conditioner in the middle of a heatwave — especially when your business depends on customer comfort or equipment cooling. Unplanned breakdowns don’t just disrupt operations; they cost money. Emergency callouts, replacement parts, and lost productivity can quickly add up. Regular maintenance allows engineers to: Spot worn or failing components early Replace filters before they become clogged Check refrigerant levels for efficiency Ensure the system is operating safely A simple biannual service can help prevent the majority of costly breakdowns — saving hundreds, if not thousands, in emergency repairs over the life of your system. 2. Lower Energy Bills with a More Efficient System An air conditioning system that’s not maintained properly has to work harder to achieve the same level of cooling. Over time, dirt build-up, blocked filters, and low refrigerant levels can reduce efficiency by up to 30% . That means you’re paying more for less cooling — and wasting energy in the process. Regular maintenance ensures your system is: Operating at peak efficiency Properly calibrated for your space Using energy-saving inverter technology effectively For many London businesses, simply keeping up with routine servicing can reduce energy bills enough to pay for the maintenance itself . 3. Extend the Lifespan of Your Equipment Commercial air conditioning systems are a significant investment. Regular maintenance helps protect that investment by keeping every component — from compressors to fans — in top condition. Without proper care, systems may need replacing years earlier than expected. But with consistent maintenance, your unit can last well beyond its standard lifespan. Think of it like maintaining a company vehicle: a small investment in servicing prevents major breakdowns and keeps things running smoothly. 4. Maintain a Comfortable and Productive Workplace Comfortable employees are productive employees. Studies show that workplace temperature and air quality directly impact focus, morale, and overall performance. A well-maintained air conditioning system ensures: Consistent temperatures across offices or retail spaces Better air quality by removing dust and allergens A pleasant environment for staff and customers alike In London’s competitive business landscape, creating a comfortable, professional atmosphere can make a real difference — especially for client-facing environments like restaurants, salons, or retail stores. 5. Protect Sensitive Equipment and Inventory For some businesses, air conditioning is about more than comfort — it’s about protection. Data centres, server rooms, and even retail stockrooms rely on stable temperatures to keep technology and products safe. Regular maintenance prevents fluctuations that could damage equipment or trigger costly downtime. At INS Air Conditioning , we maintain systems for: Offices and coworking spaces Schools and universities Data centres and IT facilities Retail stores and restaurants Healthcare and dental clinics Each environment has unique requirements, but the principle is the same: prevention is far cheaper than repair . 6. Stay Compliant and Safe Commercial air conditioning systems in the UK must comply with several regulations — including F-Gas certification , refrigerant handling rules, and periodic leak checks. By partnering with a certified London air conditioning company like INS Air Conditioning , you ensure your business stays compliant with UK environmental and safety standards. Regular servicing also includes: Checking for refrigerant leaks Verifying correct pressure and electrical connections Confirming filters and coils are clean and efficient This not only reduces risk but also ensures your system runs legally and responsibly. 7. Predictable Costs and Peace of Mind With an ongoing maintenance plan, you’ll know exactly what you’re spending — and when. Instead of surprise breakdowns or emergency call-out fees, you’ll have predictable, manageable servicing costs. At INS Air Conditioning , we offer flexible commercial maintenance contracts tailored to London businesses. You can choose from: Pay-as-you-go servicing – great for smaller offices or retail units. Annual maintenance plans – ideal for multi-unit systems or larger sites. Each plan includes priority booking, performance checks, and detailed service reports — giving you complete peace of mind. 8. The Cost of Not Maintaining Your System Let’s put the numbers in perspective. A new commercial air conditioning system can cost anywhere from £3,000 to £20,000+ , depending on size and complexity. A professional maintenance visit, by contrast, is typically a few hundred pounds. When you consider the savings on energy, repairs, and equipment lifespan, regular servicing easily pays for itself many times over . Neglecting maintenance, on the other hand, can lead to: Higher monthly bills Frequent breakdowns Shortened system lifespan Lost revenue from downtime It’s not just about keeping things cool — it’s about keeping your business running efficiently. 9.

As temperatures drop and London’s chill sets in, many homeowners start thinking less about cooling and more about keeping warm. But here’s something many people don’t realise: your air conditioning system can heat your home, too — and it can do so efficiently.

Modern air conditioning systems that double as air-to-air heat pumps are among the most efficient ways to heat your home. Unlike traditional electric heaters, they transfer heat rather than generate it, using far less energy. Key benefits include: Lower energy bills – up to 30–40% cheaper than electric heating. Cleaner heating – no fossil fuels or emissions inside your home. Dual functionality – enjoy cooling in summer and heating in winter. Eco-friendly operation – using low-impact refrigerants like R32. If your home currently relies on electric radiators or older systems, upgrading to a modern air conditioning unit can dramatically reduce your energy usage and improve year-round comfort.  How to Maximise Efficiency This Winter To get the most from your air conditioning system during colder months: Clean or replace filters every few months for smooth airflow. Keep the outdoor unit free from leaves and debris. Schedule a professional service before peak winter use. Use the timer or smart app to pre-warm rooms instead of running continuously. At INS Air Conditioning , we offer affordable maintenance and servicing plans that keep your system running efficiently, whatever the season.

Why this quieter season is actually the best time of year to have your AC system professionally serviced. When the summer heat fades and autumn arrives, most homeowners and businesses stop thinking about their air conditioning. But this quieter season is actually the best time of year to have your AC system professionally serviced. Whether you rely on your unit purely for cooling or you use a heat pump system to heat your property in the colder months, autumn servicing can help you: Avoid unexpected breakdowns later in the year Keep running costs low Extend the life of your air conditioning system Plan ahead before the busy summer rush returns If you live or work in London, now is the ideal time to give your system the care it needs. Avoid the Summer Rush Summer in the UK can catch people off guard, and when the first heatwave hits, demand for air conditioning services skyrockets. Engineers become fully booked for emergency call-outs, breakdowns, and new installations. Waiting until next summer to book a routine service can mean: Long waiting times for appointments Higher emergency call-out fees The stress of trying to fix your system when you need it most By booking in autumn, you’ll enjoy: Faster booking times: Engineers’ schedules are less busy. Flexible appointments: You can pick a date and time that suits you. More thorough attention: Technicians aren’t rushing to fit in last-minute emergency jobs. Essentially, autumn is the calm before the storm — perfect for proactive maintenance. Prevent Costly Winter Breakdowns If your air conditioner doubles as a heat pump (many modern systems do), it’s about to switch roles — from cooling to heating. Servicing now ensures it’s ready for that transition. A neglected system can: Struggle to produce warm air efficiently Break down on cold days when you rely on it most Require urgent, expensive repairs Even if you don’t plan to use your AC for heating, servicing before the long winter shutdown is still smart. Your engineer will check for issues like leaks, blocked drainage, or electrical problems, helping your system start up smoothly when summer returns. Improve Energy Efficiency Before the Cold Hits Energy bills are a hot topic in the UK, and an inefficient air conditioning system can quietly drive them up. Dust, blocked filters, and low refrigerant levels all force your AC to work harder, using more power. A professional service can: Clean internal components for smoother airflow Check refrigerant levels to maintain optimum performance Inspect electrical connections for safe, efficient operation Ensure your thermostat and controls are working correctly This means lower running costs whether you’re cooling in summer or heating in winter. It’s a simple step that can pay for itself in energy savings. Extend the Lifespan of Your System Air conditioning is an investment — and like any major appliance, it lasts longer when it’s looked after. Annual servicing in autumn helps to: Catch minor issues before they turn into major breakdowns Keep parts running smoothly, reducing wear and tear Protect your manufacturer warranty (many require annual servicing) With proper care, a good system can last 15–20 years or more. Skipping maintenance can dramatically shorten that lifespan and lead to expensive replacements sooner than necessary. What Our Professional Service Includes At INS Air Conditioning, we offer a thorough, manufacturer-approved service designed to keep your system reliable and efficient. Our typical autumn maintenance visit includes: Full inspection of indoor and outdoor units Cleaning or replacing air filters Checking refrigerant levels and topping up if needed Inspecting electrical connections and safety controls Cleaning evaporator and condenser coils for better airflow Testing system performance in both heating and cooling modes Checking drainage and condensate pumps This isn’t just a quick clean — it’s a full health check for your system. Perfect Timing for Upgrades or Repairs Another advantage of servicing in autumn is time to plan. If your engineer spots a developing fault or your system is ageing and inefficient, you have the whole off-season to: Compare replacement systems Take advantage of off-season installation discounts Schedule work at a time that won’t disrupt your summer comfort Replacing or upgrading in winter also avoids the supply chain pressures and longer lead times that can happen in summer. Ideal for Both Homes and Businesses INS Air Conditioning services residential properties, offices, retail spaces, and commercial buildings across London. The autumn servicing approach is valuable for everyone: Homeowners: Keep bedrooms, lounges, and home offices comfortable and energy efficient. Landlords & property managers: Ensure systems in rental properties are safe and reliable. Business owners: Avoid staff discomfort, lost productivity, and costly downtime if your AC fails mid-winter. No matter your property type, an autumn service helps protect your investment.

When the temperatures drop and heating becomes the priority, many homeowners forget about their air conditioning system. But taking a little time in autumn to prepare your AC for winter can save you money, prevent costly repairs, and ensure it’s ready to perform perfectly when summer returns . If you own a modern heat pump air conditioning system , winter preparation is even more important — because your unit may double as a highly efficient heater. This guide walks you through the essential steps UK homeowners should take. Why Winter Preparation Matters Most air conditioning units work hard during the summer months. By the time autumn arrives, filters may be clogged, components could be worn, and outdoor units might be full of dirt and debris. Leaving your system untouched all winter can lead to: Reduced efficiency when you switch it back on Musty smells caused by mould and bacteria Increased energy use and higher bills Unnecessary wear that shortens the system’s lifespan Risk of failure when you need cooling again next year If your AC is also your primary heat source , a lack of preparation could even leave you without reliable heating when you need it most. Step 1: Clean or Replace Filters Dirty filters are one of the most common causes of poor air conditioning performance. Before the colder months set in: Remove and clean washable filters using warm water and mild detergent. Replace disposable filters if they’re clogged or worn. Check manufacturer guidelines for your system’s specific filter type. Why it matters: Clean filters mean better airflow, improved air quality, and reduced strain on the unit — especially if you’ll be using the heating mode over winter. Step 2: Inspect the Outdoor Unit Your outdoor condenser works hard to expel heat during summer. Autumn is the perfect time to: Clear away leaves, twigs, and dirt. Make sure the unit has at least 30cm of clear space around it. Check that drainage holes or pipes are not blocked. If your property is prone to falling leaves or debris, consider adding a protective winter cover designed for air conditioning units. This keeps out moisture, dirt, and snow while still allowing airflow. Step 3: Check for Unusual Noises or Smells When you switch the unit on for a quick test, listen and smell carefully: Grinding or rattling noises could signal loose parts or worn bearings. Musty smells may mean mould growth inside the indoor unit. Burning smells should be treated as urgent and checked by a professional. Spotting these issues early prevents bigger problems and expensive repairs later. Step 4: Switch to Heat Pump Mode (If Available) Many modern UK air conditioning systems are actually heat pumps — they can reverse their cycle to provide efficient, low-cost heating. If yours offers this function: Check the mode on your remote or thermostat. Test the heating feature on a mild day. Ensure warm air flows consistently and the outdoor unit runs smoothly. If heating isn’t working as expected, schedule a service now rather than waiting until the first cold snap. Step 5: Schedule a Professional Service While homeowners can handle simple cleaning and visual checks, professional servicing is essential for long-term reliability. An engineer can: Inspect and deep clean indoor and outdoor coils Check refrigerant levels and top up if required Test electrical components and controls Identify worn parts before they fail Run the system in both cooling and heating modes Servicing now also means you’ll avoid the busy summer period and have peace of mind all winter. Step 6: Upgrade Old or Inefficient Systems Before Next Summer If your system is more than 10–12 years old, autumn and winter are the ideal times to plan a replacement. Upgrading now means: No panic buying during a heatwave Better pricing and faster installation Access to modern, energy-efficient models that can heat and cool your home year-round You’ll also enjoy lower running costs from day one.

Can an Air Conditioner Heat Your Home? If you’ve ever looked at your air conditioner in the middle of winter and wondered, “Could this thing actually warm my house?” — the answer might surprise you. Many of the modern air conditioning systems fitted in homes across London aren’t just built for cooling. They’re heat pumps — meaning they can reverse their cycle and provide cosy, efficient heating when the temperature drops. Yet lots of homeowners still don’t realise they’re sitting on a potential alternative to traditional heating. In this post, we’ll explore how it works, why it can be a smart move for your energy bills, and what to check before switching your system into heating mode. So… Can an Air Conditioner Really Heat Your Home? Yes — if you have a split system or multi-split air conditioner installed in the last decade or so, there’s a very good chance it’s a heat pump. A heat pump doesn’t actually “create” heat the way a gas boiler or electric heater does. Instead, it works a bit like magic — or, more accurately, clever physics. It moves heat from one place to another. In the summer it pulls warmth out of your indoor air and dumps it outside. In winter it reverses, extracting heat from the cold outdoor air and bringing it inside. It sounds odd — how can it take heat from cold air? But even when it feels chilly outside, there’s still usable heat energy in the air. Heat pumps are designed to capture it and transfer it into your home. Why You Might Want to Use Your AC for Heating The big draw is efficiency. Heat pumps can produce three to four times more heat energy than the electricity they consume. That makes them far more efficient than standard electric heaters and often cheaper to run than older gas systems — especially if energy prices keep rising. There are other perks too: You already own the equipment — no need for extra heaters. The air feels comfortable and evenly distributed rather than dry or stuffy. Many units let you control each room separately, so you’re not wasting heat where you don’t need it. The system runs quietly and can be managed with a remote or smart controls. For homeowners who mainly heat one or two rooms (like a home office or a bedroom), this can be a game-changer in winter. Things to Check Before Switching to Heating Mode Before you flick the remote to “heat” and hope for the best, there are a few sensible steps: First, give the unit a quick clean. Dirty filters can make the system work harder, costing you more and reducing the warmth you feel. If you haven’t done it recently, now’s a good time. Next, test it on a mild day. Don’t wait until it’s freezing — switch to heating mode and see how it performs. You should feel warm air within a few minutes and notice the outdoor unit starting up quietly. If the heat seems weak, the air smells musty, or you hear strange noises, it’s worth calling a professional. A quick service can often fix small issues and get the system running at its best. (And if you haven’t had it serviced for a while, it’s wise to do so before winter really sets in.) Heat Pumps vs Traditional Heating — Which Is Better? There isn’t one right answer for everyone. If you have a modern, efficient gas boiler and a well-insulated house, that might still be your cheapest option for whole-home heating. But if you: Only want to heat specific rooms, Want more control over when and where you use energy, Or are looking for a way to cut bills without installing a new system… …then using your air conditioner as a heater can make a lot of sense. Many London homeowners now run their living rooms or home offices on a heat pump through the day, keeping the gas boiler off until evening. It’s a flexible, efficient way to stay warm without wasting energy. Why a Service Visit Is Worth It If you’re planning to rely on your AC this winter, having it checked over is a smart move. A professional engineer can make sure it’s running efficiently, check refrigerant levels, and spot small issues before they turn into big repairs.

Energy-Efficient Heating with Modern Air Conditioning Energy bills have been a hot topic in the UK for the last few years — and with colder weather on the way, many homeowners are wondering how to stay warm without breaking the bank. If you’ve got a modern air conditioning system, you might already have one of the most efficient heating solutions available: a heat pump. Today’s air conditioners aren’t just for cooling anymore — they can heat your home effectively, quietly, and at a lower running cost than many traditional systems. Here’s how they work, why they could save you money this winter, and when it might make sense to upgrade your system. How Modern Air Conditioning Saves on Heating Costs Unlike electric heaters that burn energy to create warmth, heat pump air conditioning systems work by moving heat rather than generating it. Even when it’s cold outside, there’s still heat in the air — and heat pumps are clever enough to extract it and bring it indoors. For every 1kW of electricity a modern heat pump uses, it can often deliver 3–4kW of heat into your home. Compare that to electric radiators, which only ever return 1kW of heat for every 1kW of power used, and you can see why running costs are dramatically lower. In short: you get more heat for the money you spend. Heat Pumps vs Other Heating Options If you’re wondering how air conditioning heating compares to your other choices, here’s the picture in simple terms: Electric Heaters: Easy to plug in, but very costly to run long-term. Gas Boilers: Still common, but prices fluctuate and whole-home heating isn’t always necessary if you’re mostly in one or two rooms. Modern Heat Pump Air Conditioning: Highly efficient, great for targeted room heating, cheaper to run than electric heaters, and often competitive with gas. Many UK homeowners now use their heat pump air conditioning to warm key spaces during the day, then switch to central heating only when the whole house needs it. It’s a flexible way to cut bills without sacrificing comfort. Extra Savings with Smart Controls Most newer air conditioning systems come with smart controls or Wi-Fi connectivity, letting you: Set heating schedules that match your routine. Pre-heat a room before you wake up or get home. Avoid wasting energy on empty spaces. Some models even let you monitor real-time energy usage so you can see exactly how much you’re saving. When to Consider an Upgrade If your system is more than 10 years old, you might not be getting the best energy savings. Technology has moved on — today’s inverter-driven, A+++ rated systems are far more efficient than older models. An upgrade can pay off quickly through lower running costs, especially if you’re using the system daily in winter. Autumn and winter are also the ideal time to install. Engineers are less busy, and you’ll be ready long before next summer’s rush.

If you’ve ever searched for air conditioning in London, you’ve probably noticed one thing: prices vary — a lot. Some companies promise super-cheap installs, while others talk about long-term value and premium systems. So how much should you actually expect to spend in 2025, and what really drives the cost up or down? The truth is, there’s no single price tag that fits every home. But once you understand the main factors that affect installation costs, it’s much easier to plan your budget — and avoid surprises. Why Prices Can Vary So Much Think of air conditioning like buying a car: you can choose a small, simple model or a high-tech luxury option. Both will get you from A to B, but the cost, comfort and efficiency are worlds apart. Some of the biggest things that influence price are: Your home’s size and layout. A single bedroom might only need one indoor unit, while a large house may need multiple rooms cooled or heated. The type of system. Split, multi-split and ducted systems all come with different price ranges and installation complexity. Brand and efficiency. Premium brands like Mitsubishi or Daikin can cost a little more upfront, but usually last longer and run more efficiently — saving you money over time. Installation complexity. Easy-access walls and clear outdoor space mean simpler work (and lower costs). Difficult runs, tricky wiring or tight spaces can add labour hours. When you call a company like INS Air Conditioning, we don’t just throw out a random figure — we look carefully at your space, your comfort goals and your energy efficiency needs to recommend the right system. Typical Price Ranges in London (2025) While every property is unique, here’s a realistic guide for homeowners planning air conditioning this year: A single room (like a bedroom or home office) with a quality wall-mounted split system often starts from £1,500 – £2,500, fully installed. A multi-room system for a flat or small house can range from £3,500 – £6,000, depending on how many indoor units are needed. Larger homes or properties looking for a ducted system — hidden pipes, discreet vents — may see costs from £6,000 upwards, especially if installation is complex. These figures cover equipment, installation and VAT but can still vary based on the factors above. That’s why a free survey is so important: it turns guesswork into a clear, fixed quote. The Hidden Cost of Going Too Cheap It can be tempting to pick the lowest quote you find online — especially when budgets are tight. But poorly installed systems often cost more in the long run. We regularly see issues such as: Incorrect pipework that causes leaks and poor performance Systems under- or over-sized for the space (leading to high bills or uncomfortable rooms) Noisy operation because installation wasn’t done carefully Shortened lifespan due to lack of proper commissioning A quality installation may cost a bit more upfront, but it usually pays for itself in reliability, energy savings and peace of mind. Why Autumn and Winter Are a Smart Time to Install Most homeowners only think about air conditioning when the heat hits — but by then, installers across London are booked solid. Right now (autumn and winter), things are calmer. That means: Faster installation dates without long waiting lists More time to plan and ask questions Competitive pricing — some companies offer off-season deals  If you know you’ll want cooling next summer, it’s smart to install before demand spikes.
