RightAir Solutions is a company that specialises in commercial air conditioning services.
An air conditioning unit in the UK typically lasts between 12 and 20 years depending on the type of system, how it is installed, and how well it is looked after. Central air conditioning systems often run reliably for 15 to 20 years when serviced regularly, while portable or window units may need replacing after 8 to 10 years. Signs such as higher electricity bills, repeated breakdowns, or using banned refrigerants like R22 refrigerant usually mean it’s time to start thinking about a new unit.
These systems usually provide reliable service for 12 to 17 years and can last up to 20 years with ongoing care.
These are efficient systems that tend to work well for 15 to 20 years, especially when filters and coils are cleaned regularly.
These smaller systems last about 8 to 10 years. Changing the filter regularly can help stretch their lifespan.
Due to lighter build quality and frequent movement, portable units last between 5 and 10 years.
Pro Tip: Changing your filters regularly is the simplest way to extend the life of your system and reduce energy bills.
Units that are not installed properly often develop problems early on. Proper airflow and refrigerant charge at the start make a noticeable difference.
An oversized unit will switch on and off more than needed, which causes wear. An undersized unit may constantly run without effectively cooling the room. Either situation shortens the system’s useful life.
In areas with damp or coastal air, equipment may corrode faster. In dusty or high pollen zones, clogged filters can strain internal parts.
Checking refrigerant levels, cleaning coils, inspecting electrical components, and replacing filters regularly all help to keep things running smoothly and efficiently.
Pro Tip: Always ask your installer to run a load calculation for your home. A unit that is too big or small can shorten its lifespan and waste energy.
If repair costs are more than half the price of a new system, replacing the unit is usually a better option. New systems often come with better warranties and use much less electricity, which saves money over time. If your current system runs on R22 refrigerant or is frequently breaking down, it’s worth looking into a newer and more efficient model.
Keep your system running smoothly year-round with our affordable servicing plans, available across the UK.
The use of R22 refrigerant is now banned for servicing in the UK, meaning systems that rely on it can be difficult and expensive to maintain. Newer systems use refrigerants such as R32 or R410A, which are better for the environment and easier to top up or repair. Making the switch ensures your home stays compliant and avoids rising repair costs in future.
Salt in the air can corrode metal coils quickly. If you live near the sea, choose a corrosion-resistant system and clean the external unit regularly.
Pollution and dirt from traffic settle on coils and filters, making it important to clean components more frequently.
Pollen, dust, and organic debris clog filters quickly. You may need to change filters more often, particularly in spring and summer.
Dirty filters reduce airflow and make the unit work harder. Over time, this strain shortens its lifespan. Air purifiers, regular filter replacements, and good ventilation can help keep both your air cleaner and your system running longer.
Start by checking the plug, circuit breaker, thermostat settings, and filter condition. If these are all in order, contact a professional. Issues like a blocked condensate line or capacitor failure are common and can often be fixed quickly. However, if the compressor or motor is damaged, a replacement might be more cost-effective.
Make sure the unit suits your home’s layout and size. Good insulation and air circulation mean your system does not have to work harder than it should.

New systems cool more evenly, use less electricity, and produce less noise. They also have better filters that improve indoor air and are built with environmentally safer refrigerants. Many units now include smart sensors and apps, letting you adjust temperatures remotely or monitor efficiency in real time.
Upgrading is not just about replacing an old unit. It can mean better air quality, consistent comfort, and lower energy costs every month.
Your air conditioning unit plays a big part in keeping your indoor space comfortable. How long it lasts depends on care, usage habits, and how well it suits your home. If you have had your system for more than 15 years or are facing frequent repairs, it may be time to consider an upgrade. A new system can improve comfort and lower running costs.

Can an air conditioner last 30 years? Most systems do not last that long. Even with perfect maintenance, efficiency drops and repair costs increase after about 20 years.
What causes an air conditioner to wear out faster? Lack of maintenance, incorrect installation, poor ventilation, and exposure to harsh environmental conditions will reduce lifespan.
How much will a new air conditioner cost in the UK? Prices usually range from £2,500 to £6,500 depending on the type of system and the size of the home.
Is it bad to run the air conditioner all the time? It is fine if the system is sized correctly and well maintained. Smart thermostats can help reduce unnecessary use.
What is the best way to winterise the outdoor unit? Use a cover that allows airflow. Avoid wrapping it with airtight material, which can trap moisture.
Can indoor air pollution affect how well my air conditioner works? Yes. Dust and airborne particles can clog the system and reduce performance. Regular filter changes help prevent this.
What is the best summer temperature setting? Between 22 and 24 degrees Celsius helps maintain comfort without putting strain on the system.
Are ductless systems more durable? They can be, especially in smaller homes or rooms with specific cooling needs. They also have fewer moving parts.
Should I upgrade if my system uses R22? Yes. R22 is banned and systems that rely on it are expensive to repair and service.
What happens during a maintenance visit? The engineer checks refrigerant levels, inspects the coil and fan, tests electrical parts, and ensures the system is working safely and efficiently.
