Air conditioning installation in Harefield
A new system normally needs a dedicated circuit from the fuse board. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Southampton.
New circuits are done by our NICEIC approved electricians, so there’s no separate electrician or building control visit to arrange.
Homes around Harefield are mostly houses, many with gardens, so there’s normally space for the outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.
Refrigerant work is written up in the F-Gas records: 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.

Rented and managed buildings
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.
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 arrange the inspection, get the system ready and put right anything it picks up.
The process
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Getting to the outside of the property matters more than parking in a place like Harefield.
- You send pictures, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Keep pets out of the rooms we’re working in
- Have the make and model of any existing unit to hand
- Move furniture away from the wall where we will be working
Getting a price
Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749 or write to us at info@aircondoctor.co.uk.

After we’ve gone
So the system stays in good health:
- Have the system serviced once a year
- Do not cover or box in the outdoor unit
- Clean the filters every few weeks when the system is in heavy use
You get the paperwork that matters: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together as they’re needed for servicing and any warranty question.
Book an annual service. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.
Homes in Harefield and air conditioning
At about 3 miles from the coast, Harefield is close enough for sea air to matter. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we’ll tell you if the model you choose has that option. Valuation Office Agency council tax records date about 51% of homes across Harefield and its surrounding area to the post-war years, 1945 to 1972. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route.
About 1.9 miles north-west stands South Stoneham House. Listed homes in any area need consent first, so tell us if yours is one. Homes near Church of St James are a good example of where we look up the heritage status of the building before fixing anything to it.

Common questions in Harefield
Do you cover Harefield for air conditioning?
We do: Harefield falls inside our working area. Just call us on 07833 053749 or use the quote form with a few details.
Does sea air affect air conditioning in Harefield?
It can, as Harefield is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
How long does air conditioning installation take?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote so there are no surprises.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is planning permission needed for the outdoor unit?
That depends on what’s being fitted and where. Heat pumps on houses in England can be permitted development when they meet set conditions, including the MCS 020(a) noise check, but a cooling-only unit is not covered, so check with the council. Flats, listed buildings and conservation areas have tighter rules. This is general information, not legal advice.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Leave it or put it right?
If you are thinking about air conditioning for a property in Harefield, there’s no need to wait for a heatwave. Installation takes anything from a day for one room to several days for a multi-room or ducted system, and the date is agreed with you once you are happy with the quote. Waiting rarely makes an air conditioning problem smaller.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, give us a ring on 07833 053749 or fill in the contact form and we’ll give you an honest view and a fixed price.
