Air-to-air heat pumps for Caernarfon homes
A heat pump suits most Caernarfon homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For terraced homes in Caernarfon, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room. A survey in Caernarfon covers indoor unit positions, pipe routes and hot water for homes across Gwynedd.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Condensate drains and neat external pipe covers
- Free survey covering rooms to heat, unit positions and hot water options
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
Extensions and garden rooms in Caernarfon that are hard to connect to the main heating can have their own air-to-air unit.
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Caernarfon quote.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.
Air-to-air heat pumps prices in Caernarfon
The ranges below are typical installed prices for homes in Gwynedd, including VAT. A survey sets the exact figure, because two similar-looking houses in Caernarfon can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,400–£5,000 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.
How long is the heating season in Caernarfon?
On the shortest day Caernarfon gets about 7 hours 32 minutes of daylight, with the noon sun around 13° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air-to-air heat pumps in Caernarfon: questions
How long does installation take in Caernarfon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Caernarfon home states the expected time.
Do I need new radiators for a heat pump in Caernarfon?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Caernarfon home gives a room-by-room list.
What size heat pump does a Caernarfon home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Caernarfon home.
How much sound do the indoor units make?
Indoor units are designed to run quietly, with a fan you will hear most when heating or cooling at full output. Lower fan settings and night modes reduce sound in bedrooms. Siting matters for the outdoor unit too: it needs airflow and a position that passes the MCS noise assessment. Ask to see the sound levels of the proposed units at survey.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
