Dunn Street air source heat pumps
Air source heat pumps in Dunn Street from an F-Gas certified company, with the manufacturer’s warranty terms explained on your quote. We reply to enquiries the same working day.
- Ageing boilers that will need replacing
- Moving away from fossil-fuel heating
- Radiators that may be too small for a heat pump
Let and managed properties
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
How we handle air source heat pumps in Dunn Street
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. The work covers homes heated by oil, LPG or gas, hot water cylinders and underfloor heating, and people most often call us about questions about the Boiler Upgrade Scheme and finding a place for the outdoor unit.
Older and listed homes in villages like Dunn Street need extra care, and permitted development doesn’t cover listed buildings, so consent comes first.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

The process
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A few pictures help us make the most of a visit to Dunn Street.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Arrange for someone to be there to let us in
- Clear access to the fuse board
- Mention any roof access, ladders or high-level work
How to get a quote
Quotes don’t take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
Advice
Keeping the system healthy
Systems last better with the right care. Here’s what we suggest:
- Don’t block radiators or indoor units with furniture
- Keep to regular servicing
- Ask about the grant before you commit
Equipment warranties come from the manufacturer. We go through the conditions with you, including any servicing they ask for.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.

What affects the quote in Dunn Street
The diagnosis comes before the price. We look at:
- What electrical work the job needs
- The size of the job
- The equipment or parts the job needs
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we will explain each part.
Helping us quote
Good pictures often save a visit. Try to include:
- Wide pictures of the room or the existing unit
- The rating plate or label on any existing unit
- The outside wall, roof or yard where the outdoor unit sits or would go
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To start, call 07833 053749 or send an email.
