FAQs

Got questions?
We've got answers

Can Relair both heat and cool my room?
Yes! Relair is a reverse-cycle heat pump that provides both cooling in summer and heating in winter from the same unit. In heating mode, it extracts heat from outdoor air (even when cold) and transfers it inside. It's highly efficient - for every 1kW of electricity, it can produce up to 4kW of heat. Many customers use it as their primary heating in mild weather, or to supplement central heating in specific rooms.
How much does air conditioning cost to run?
Running costs depend on the unit size and usage, but Relair's A+++ efficiency makes it very economical. A typical 3.5kW unit costs around 15p per hour to run in cooling mode at current electricity prices. That's about £1.20 for an 8-hour day, or £36/month of regular use. Compare this to portable AC units (£3.60/day) or electric heaters (£7.20/day for 3kW). The inverter technology means it only uses what's needed, reducing costs further.
How noisy is the Relair system?
Relair is designed for exceptionally quiet operation. The indoor unit's silent mode operates at just 19dB - literally quieter than a whisper (20dB) or rustling leaves. Normal operation is around 26-32dB on low speed, similar to a quiet library. Even at high speed, it's only 38-45dB - quieter than normal conversation. The outdoor unit operates at 48-52dB, comparable to a refrigerator, with a night mode reducing this further.
Where do the indoor and outdoor units go?
The indoor unit is typically wall-mounted high on an internal wall, ideally opposite a door or in a position that allows good airflow across the room. Avoid placing it directly above beds or seating areas. The outdoor unit needs adequate ventilation and is usually mounted on an external wall bracket (at least 2m high) or a ground stand. We'll survey your property and advise on optimal positioning during our free site visit.
Do I need planning permission for air conditioning?
For most residential installations, no planning permission is required under permitted development rights, provided: the unit doesn't project more than 1m from the wall, no part is higher than the highest point of the roof, and it's not on a wall facing a highway (if in a conservation area). We'll advise if your property has any restrictions during the survey.
Can I install multiple units in my home?
Absolutely! For larger homes or multiple rooms, we offer multi-split systems where one outdoor unit can connect to 2-5 indoor units, each with independent temperature control. This is more efficient and aesthetically pleasing than multiple separate systems. We can also install several single-split systems if your requirements demand it.
How effcient is Relair compared to portable air con?
Relair is dramatically more efficient than portable units. A portable AC rated at 3.5kW cooling typically consumes 1.3-1.5kW of electricity (EER ~2.5), while Relair achieves the same cooling using only 0.6-0.8kW (EER ~5.0). That's roughly half the running cost. Portable units also exhaust hot air through a window, often creating negative pressure that draws warm air back in through gaps. Split systems like Relair have no such losses.
