About our air source heat pumps in Wimbish Green
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. Common call-outs are for wanting to stop using oil, LPG or gas for heating and comparing heat pump types, on radiator systems, underfloor heating and air-to-air heat pumps.
In a place like Wimbish Green, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What we do, step by step
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Visits to Wimbish Green are agreed with you in advance and planned so the job can be finished in one trip where possible.

Air source heat pumps around Wimbish Green
On the National Heritage List, around 13 entries fall within 0.5 miles of the middle of Wimbish Green; Joyce's Cottages (grade II) is one. Where a home is affected, the outdoor unit position is settled with Uttlesford council, usually the planning authority here before the heat pump design is finished. About 80% of households live in detached or semi-detached houses, according to Census 2021 figures. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Live in one of the older houses around St Paul's Mission Room? Expect the survey to look closely at heat loss and at the building’s planning status.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Common problems we fix in Wimbish Green
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity and that is the appeal for many households.
If any of these sounds familiar, it’s worth a diagnosis:
- An oil, LPG or gas boiler near the end of its life
- Questions about the Boiler Upgrade Scheme
- Choosing between air-to-water and air-to-air
Historic houses such as Horham Hall, about 3.8 miles south, are a reminder that listed homes need consent before a heat pump goes in.

Common questions in Wimbish Green
Is the heat pump grant available in Wimbish Green?
Wimbish Green is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Is Wimbish Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll tell you what to do first.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
How much time does a heat pump install need?
Expect it to take from a couple of days to around a week, depending on the system and how much of the heating changes. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and we hold it.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.

Pricing air source heat pumps in Wimbish Green
Every job gets its own quote. These are the things that affect it:
- The equipment or parts the job needs
- How far the pipework has to run, and where
- Whether we need access equipment for high-level work
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- The address and the type of property
- A close-up of the unit’s label showing the model number
- Where the outdoor unit is, or where you’d like it
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
