Heat Pump Servicing FAQs

It depends on the size of heat pump your home needs, whether any radiators need upgrading and whether you need a new hot water cylinder. We give you a written quote after surveying your home. For most homes in England and Wales, the Boiler Upgrade Scheme grant, currently £7,500, comes off that price.

Usually, if your home is in England or Wales and you are replacing a fossil fuel heating system such as oil, LPG or gas, or electric heating. The heat pump must be fitted by an MCS certified installer, which we are. We confirm your eligibility at the survey.

Most homes take a few days on site. It takes longer when several radiators or the hot water cylinder need replacing. We confirm the timescale in your quote, and you are only without heating for part of that time.

Not always. A heat pump runs at a lower water temperature than a boiler, so some rooms may need a larger radiator to stay warm. The heat loss survey shows which rooms need one, so you only replace the radiators that need it.

Yes. We repair air source heat pumps whoever installed them. Our engineers are F-Gas registered, so they can also work on the refrigerant side of the system, which many heating engineers cannot.

Yes. We install, maintain and repair heat pumps for businesses, including planned maintenance and F-Gas leak checks. We also look after commercial air conditioning and refrigeration, so one team can cover all your systems. Commercial maintenance is quoted for each site.

Yes. Air source heat pumps take heat from the outside air even when it is well below freezing, and models sold in the UK are designed for our winters. Correct sizing matters most: a system designed for your home's heat loss keeps it warm on the coldest days.

Once a year. Most manufacturers need a yearly service to keep the warranty valid, and it keeps the system running efficiently. Our heat pump servicing plans include the annual service and a PDF report for your records.

Yes, for emergencies. If your system has failed, we aim to get an engineer to you the same day. If a part needs ordering, we tell you when it will arrive and book the return visit with you.

The most common causes are a blocked filter, a dirty outdoor unit, low refrigerant from a leak, or a fault with the fan or compressor. Check the filter and that nothing is blocking the outdoor unit. If it still isn't cooling, it needs an F-Gas registered engineer.

Usually because the condensate drain is blocked, so water that should drain away overflows from the indoor unit. It can also be a sign the coil is freezing up. Clearing the drain is part of every service.

At least once a year, ideally before summer. Systems that run all year, such as server room cooling, may need servicing more often. Many manufacturers also expect regular servicing to keep the warranty valid.

Yes. We repair, service and install air conditioning in homes as well as businesses, from a single bedroom unit to systems covering a whole building.

Yes. We repair and service all major makes of air conditioning, whoever installed them.

Yes. We fit wall-mounted, ceiling cassette and ceiling-suspended systems. We survey the rooms first, then send a written quote that sets out what's included.

Larger systems, which are common in businesses, must have regular leak checks by an F-Gas registered engineer, and the results must be recorded. How often depends on the type and amount of refrigerant. We can tell you what your system needs and carry out the checks.

Yes. We answer emergency calls 24 hours a day, 7 days a week, because a failed cold room or freezer puts stock at risk within hours.

Keep the doors closed, write down the temperature readings and when you noticed the problem, and move high-risk food or medicines to working storage if you can. Then call us.

Common causes are a dirty or blocked condenser, ice on the evaporator, worn door seals, a faulty fan, or low refrigerant from a leak. Check the doors are closing properly and nothing is blocking the condensing unit, then call an engineer.

Usually a defrost fault, a door left open or a poor door seal letting in warm, damp air. Low refrigerant can also cause it. Ice blocks the airflow, so the unit struggles to hold temperature until it is fixed.

At least once a year. Equipment in busy kitchens, or units that run hard in warm spaces, often benefits from visits every three to six months. We recommend a schedule based on your equipment and how it is used.

Yes. Contracts are quoted for each site, with visits planned around your opening hours, F-Gas leak checks where they are needed and records of the work done.

Yes. We install cold rooms, condensing units and refrigerated display cabinets. We survey the space first, then send a written quote that sets out what's included.

Often, yes. But if the system is over 10 years old and needs a major repair, such as a new compressor, replacing it can work out cheaper over time. We'll explain the options so you can decide.
