Frequently Asked Questions

Yes. Modern air conditioning systems are increasingly common in UK homes, especially as summers get hotter and more humid. As well as cooling, most systems double as an efficient heating source in winter, giving you year-round comfort rather than just a few weeks’ relief in summer.
An annual service is recommended to keep your system running efficiently and to protect your warranty. This typically covers cleaning or replacing filters, checking refrigerant levels, and inspecting the unit for wear – similar to servicing a boiler.
Usually not. Most residential air conditioning installations fall under permitted development rights, so no formal planning permission is required. The main exceptions are listed buildings and homes in conservation areas, where extra approval may be needed — we’ll advise on this during your free home survey.
As UK summers get noticeably warmer, a properly installed air conditioning system is becoming a more attractive feature for buyers, in the way double glazing or a modern boiler once was. It’s not a guaranteed value-add on paper, but it can make a home more appealing and comfortable to live in.
No – modern systems are highly efficient, often up to 5x more efficient than electric radiators when used for heating. Running costs depend on how often you use it and your electricity tariff, but pairing it with solar panels can bring costs down further.
Costs vary by home size and number of rooms, but typically start from around £1,500 for a single room system, rising to £3,000+ for whole-home setups. We always provide a fixed-price quote after a free home survey, so there are no surprises.
Yes. Most systems include HEPA or equivalent filters that remove dust, pollen and other particulates, while also helping control humidity – particularly useful for anyone in the household with allergies or respiratory sensitivities.
Yes – anyone installing or handling refrigerant in the UK is legally required to hold F-Gas certification. Roost Heating’s engineers are REFCOM registered, meeting this legal requirement on every air conditioning installation.
