How we handle air conditioning in Warnham
Air conditioning isn’t only for summer: most modern splits heat too. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning, so a well-chosen unit can be useful in winter as well as summer. For air conditioning in Warnham, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork, wherever you are in West Sussex.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
Homes around Warnham usually have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
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, as a manufacturer or a future engineer may ask to see them.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- A room that cannot take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
- Problems with a gas boiler or the radiators
- Draughts and missing insulation
If you are not sure, just phone us on 07833 053749 or send an email and we will give you a straight answer before you book.

Managing agents and facilities teams in Warnham
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.

How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right 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 anything from a day for one room to several days for a multi-room or ducted system. Visits to Warnham are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We survey the property, or work from your photos for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any managing agent or landlord rules we need to follow
How to get a quote
Here’s what helps us quote: the address and the type of property, a few pictures, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then give us a ring on 07833 053749.

After we’ve gone
So the system stays in good health:
- Use moderate settings for comfort and economy
- Clean the filters every few weeks when the system is in heavy use
- Never run the system with the filters out
The handover includes the records you need: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together, because the manufacturer or a future engineer may ask to see them.
Have the system serviced once a year. A service cleans what you can’t reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.

FAQs for Warnham
Is planning permission needed for air conditioning in Warnham?
The answer turns on the property and where the outdoor unit would sit. The Warnham Conservation Area takes in the middle of Warnham. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Warnham, typically Horsham council) when it matters.
Do you cover Warnham for air conditioning?
We do: Warnham falls inside our working area. Get in touch with the details and we reply the same working day.
Do you offer emergency call-outs?
Yes. 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.
Which type of system should I choose?
There’s no single best type. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
What size air conditioning unit do I need?
Sizing is done on the survey, room by room. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
From one of our customers
“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.”
