Common questions in Hardham
Will you come out to Hardham?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning in Hardham without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Hardham Conservation Area, close to central Hardham. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at Horsham council, usually the authority for Hardham.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
How long does air conditioning installation take?
A single-room system is usually fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
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 is not optional: it’s required by law, and AirCon Doctor is certified.
What accreditations do you have?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.

How the visit works
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 the rest is down to us. Before we leave, the area is tidied and we explain what we’ve done. A few pictures help us make the most of a visit to Hardham.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Dig out any previous service or F-Gas records
- Clear access to the fuse board
How to get a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Why it’s worth doing now in Hardham
Refrigerant rules have changed what new systems use. Since 2025, new single split systems with less than 3 kg of refrigerant can’t use F gases with a GWP above 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Dealing with it now is normally simpler than a breakdown later.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, call 07833 053749 or email us for straight advice and a fixed price.
Why book with us
- MCS certification for heat pump work
- 24/7 emergency line for breakdowns
- A fixed price before any work starts
- A reply the same working day
Keeping the system healthy
Looking after the system is mostly common sense. Our tips:
- Keep the F-Gas records, commissioning details and warranty information together
- Keep the room closed while it runs
- Flag any change in how the system sounds or performs
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings, so you are confident using it.
Set it and leave it. A moderate set temperature cools the room just as well as the lowest one, without the waste, and close windows and doors while it’s cooling.
Landlords, agents and facilities managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
