Air conditioning for homes and businesses in Farnham
The best installations are planned before a single hole is drilled. Each room is assessed for its size, windows, direction and how it’s used, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run, all before the price is fixed. If you want air conditioning in Farnham, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork.
Space outside is rarely the problem in a place like Farnham. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Why it’s worth doing now in Farnham
Fans and portables move warm air around rather than removing it. A properly installed split moves heat outside, keeps the noisy parts out of the room and most of the time heats too, so it works for you in winter as well. Planning ahead for a job in Farnham means we can bring everything needed.
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
Why book with us
- A 24/7 emergency line
- MCS certified heat pump installers
- Fixed-price quotes after a survey or photos
- Clear warranty information from the manufacturer

Farnham questions
Is Farnham in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Farnham is part of that. Just phone 07833 053749 or use the quote form with a few details.
Do you cover smaller places like Farnham?
Yes. Farnham is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Can the outdoor unit go on a roof or at ground level?
We agree it with you on the survey. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We will tell you what to check before we fit it.
Is planning permission needed for the outdoor unit?
It depends on the system and the property. In England, an air source heat pump on a house can be permitted development if it meets set conditions, including the MCS 020(a) noise check, but a cooling-only unit isn’t covered, so check with the council. Flats, listed buildings and conservation areas have tighter rules. This is general information, not legal advice.
How long does it take to fit air conditioning?
Allow a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We confirm the time when we quote, so you can plan around it.
Homes in Farnham and air conditioning
About 18 listed entries lie within half a mile of central Farnham, Globe Farmhouse (grade II) among them. That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with the local planning authority (normally Uttlesford council) where needed. VOA council tax data show about 30% of homes in and around Farnham were built in 2000 or later. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking.
Much Hadham Palace, about 4.2 miles south-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Around Church of St Mary the Virgin, a quick check of the listing and conservation maps is part of planning any install.

How the job changes from property to property
Pipework and condensate drains
After the pipework is fitted, the refrigerant circuit is pressure tested and evacuated, so the system starts life clean, dry and leak-tight. It’s recorded in the commissioning details.
Ducted systems
A ducted system needs a ceiling void or loft deep enough for the unit and ducts plus an access hatch for maintenance. We check that on the survey before recommending one.
How the visit works
Each visit runs to the same pattern: agree the plan on site, protect the area, do the work, check the system and talk you through it. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a place like Farnham, the timing is set with you and the travel is our side of the planning.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- 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
- Unlock any gate, garage or side passage we need
- Mention any parking restrictions near the property
- Tell us about access, such as roof hatches, high walls or locked plant areas
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 many jobs can be priced from that.
Advice
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
