Air con installers in Gilston
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, along with the manufacturer’s warranty terms on your quote. Every installation in Gilston begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
For a home in or near Gilston, an air-to-air system can cool in summer and heat in the cooler months, which suits garden rooms, lofts and extensions that the main heating struggles with.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Do you need air conditioning in Gilston?
Not everyone is after cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, so it gives out more heat than the electricity it uses. That is how most modern split systems work.
These are the situations we see most often:
- Rooms heated by plug-in heaters
- An ageing air conditioning system near the end of its life
- Fans and portables that don’t keep up
About 4.8 miles north stands Much Hadham Palace. Listed homes in any area need consent first, so tell us if yours is one.

Questions from Gilston
Do you cover Gilston for air conditioning?
Yes, Gilston is within the area we cover. Get in touch with the details and we reply the same working day.
Will air conditioning in Gilston need planning permission?
It depends on the property. The half-mile around the middle of Gilston holds about 16 listed buildings and structures. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the planning department at Harlow council, usually the authority for Gilston.
What size air conditioning unit do I need?
It depends on the room, not only its floor area. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
When will I hear back?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do you protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Air conditioning in Gilston: local notes
Valuation Office Agency council tax records date about 65% of homes in Gilston and the neighbourhoods around it to the post-war years, 1945 to 1972, and about 46% of households live in terraced houses, according to Census 2021 figures. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit usually goes on the rear wall or a flat roof, with the pipe run kept short.
Homes near Parish Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it.

Why it’s worth doing now in Gilston
Refrigerant rules have changed what new systems use. Since 2025, new single split systems with less than 3 kg of refrigerant cannot 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. An early booking makes the visit to Gilston easier to arrange.
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.

The process
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Seeing the property in photos first means the trip to Gilston can be planned properly.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
How to prepare
- Tell us about parking and loading
- Name a contact who can meet us at the agreed time
- Dig out any previous service or F-Gas records
