How it works

What is an air to air heat pump?

An air to air heat pump, often shortened to A2A, moves heat between the outside air and the rooms in your home. In winter it draws warmth from outside and delivers it indoors through wall-mounted or ducted units. In summer the cycle reverses, and the same units cool the room.

It is the same technology as air conditioning. The difference is that a modern air to air heat pump is designed and rated for heating as well as cooling, so it works as a year-round system rather than a summer luxury.

Unlike an air to water heat pump, an air to air system does not heat water or run radiators. It heats and cools the air directly, room by room, which makes it fast to respond and efficient to run.

Winter heating

A well-specified air to air system delivers three to four units of heat for every unit of electricity, at outdoor temperatures well below freezing. Rooms warm within minutes rather than hours.

Summer cooling

The same units cool and dehumidify. For homes in Cambridgeshire, where summers have become noticeably hotter, this is often the reason people call us first.

Room by room control

Each indoor unit is controlled independently. Heat the rooms you use, leave the rest, and stop paying to warm empty space.

The installation is very neat looking, and all achieved with a minimum of fuss or inconvenience. My biggest praise for the company would be their communications. If they said it was going to happen - it happened, and at the timescale provided.

My parents heat pump system gave up just as the weather turned cold. Big eye watering job, but needed replacing ASAP. Turnaround time couldn't have been quicker, the engineers who did the install were all sound and did a tidy professional job. I'm still blown away by the lagging.. (there wasn't any before) it is artwork😁👌 cheers Eco installer and service ltd.

An exceptional all round experience with Eco Installer starting with my initial service enquiry efficiently handled by Annette. On the day of the service visit Chris went out of his way to educate me about heat pumps which as a life long oil boiler user was definitely needed and appreciated!

Frequently Asked Questions

Does air to air qualify for the Boiler Upgrade Scheme?

Yes. Since April 2026 the scheme has included a £2,500 grant for air to air heat pumps in residential properties. Your existing fossil fuel boiler has to be fully removed or permanently decommissioned, you will need a separate hot water solution, and it is one grant per property. We handle the application.

Yes. Modern air to air heat pumps are rated for heating at outdoor temperatures well below freezing, and are typically three to four times more efficient than electric panel heaters. Cooling is the same cycle in reverse.

It depends on the number of rooms and the type of indoor unit. A single-room wall-mounted system can be done for a reasonably small amount while a multi-room or ducted system for a whole house is of course more. We give you a fixed quote after survey, with the £2,500 grant applied where you qualify.

Indoor units run at around 20 to 30 dB on low settings, quieter than a fridge. The outdoor unit is comparable to an air source heat pump and is sited away from bedrooms and neighbours.

Usually not. Most domestic air conditioning and air to air installations fall under permitted development. There are exceptions for listed buildings and conservation areas, which we check at survey.

Yes. Air to air is often the most practical option where there is no wet heating system to connect to, such as flats, annexes, garden offices and loft conversions.

Yes. Our engineers are F-Gas certified and service air to air and air conditioning systems from all major manufacturers across Cambridgeshire.

A single-room system is usually a day. Multi-room and ducted systems typically take two to three days.
