“We was a bit unsure about getting a heat pump at first cos heard mixed things but NorthStar actually explained it all decent and didnt just try sell us one straight away. They checked house properly first and went through what would work best for us. Install took a bit of organising but lads kept us updated and got on with it. Been using it a few weeks now and house stays warm no problem and its quieter than I expected aswell.”Hollie Grogan Google review
Heat pump servicing and repairs in Sheffield
Annual servicing to keep your heat pump efficient and your warranty valid, plus fault finding and repairs on existing systems, including ones we didn't fit.
What's in a heat pump service
- Check the outdoor unit, fan and coil, and clear leaves and debris
- Check refrigerant circuit operation and pressures
- Clean the system filter and check water pressure and the expansion vessel
- Check electrical connections and the outdoor isolator
- Test the hot water cylinder, safety valves and immersion
- Review flow temperatures and controls settings, and adjust them if your bills are higher than they should be
- Fill in your service record for the manufacturer warranty
Why annual servicing matters
Most manufacturers need a heat pump serviced every year to keep the warranty valid. A service also catches small problems early, like a blocked filter or a setting that's quietly costing you money.

Inherited a badly set up heat pump?
A lot of the heat pumps we're called out to aren't faulty. They're just set up wrong, with flow temperatures too high or controls fighting each other. Often a visit to correct the settings makes a real difference to comfort and running costs.
What customers say
5-star reviews from our Google Business Profile.
“Had no idea what size heat pump we needed or whether the house would even suit one, so was half expecting a load of confusing sales talk. Didn’t get any of that. Everything was explained simply, we knew what we were paying for and the install went smoother than expected. House is heating up nicely and it’s been easy enough to get used to. Very happy we went ahead with it.”Mateusz Google review
Servicing questions
Do heat pumps need servicing?
Yes. An annual service keeps the system running efficiently, and most manufacturers need it done every year to keep the warranty valid. We service most major brands, including heat pumps we didn't fit.
How long does an air source heat pump last?
Typically 15 to 20 years with an annual service, which is longer than most gas boilers.
Does a heat pump work when it's freezing outside?
Yes. Air source heat pumps keep producing heat well below zero. We size the system to keep your home warm on the coldest days typical for Sheffield, not just an average winter day.
Are heat pumps cheaper to run than a gas boiler?
A well-designed heat pump turns each unit of electricity into several units of heat, so running costs depend mainly on how well the system is designed and which electricity tariff you use. We set the controls up for efficient running and can talk you through heat pump tariffs at handover.
