Before you book: air-to-air heat pumps in Johnstone
Most homes can run on a heat pump if the system is designed properly, and Johnstone is no different. The key is matching the heat pump and radiators to the home's heat loss.
Installers in Johnstone plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Flats in Johnstone on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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.
- Homes where fitting radiators and pipework would be very disruptive
- Rooms that get too hot in summer as well as cold in winter
- Extensions, conservatories and garden rooms
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
- Condensate drains and neat external pipe covers
A survey in Johnstone covers indoor unit positions, pipe routes and hot water for homes across Renfrewshire and Inverclyde.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Johnstone home, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Johnstone property at survey.
Air-to-air heat pumps costs around Johnstone
These are guide prices for Renfrewshire and Inverclyde, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| 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.
Designing for Johnstone's winters
On the shortest day Johnstone gets only about 6 hours 59 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.
The steps for air-to-air heat pumps in Johnstone
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Johnstone home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air-to-air heat pumps in Johnstone: questions
Where would the outdoor unit go on a Johnstone house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Johnstone home.
How long does a heat pump survey take in Johnstone?
A home survey in Johnstone usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
What size heat pump does a Johnstone 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 Johnstone home.
Are air-to-air heat pumps suitable for flats?
Often, yes. They need no radiators, pipework or cylinder, so they suit flats heated by storage or panel heaters. You need a position for the outdoor unit, such as a balcony, wall bracket or ground-floor yard, and leaseholders normally need the freeholder's or management company's consent. Planning rules for flats differ by nation, so we check what applies 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.
