What we are called out for in Farnham
Water dripping from an indoor unit is normally about the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, while ice that forms on the coil and then melts can also cause drips.
Look out for any of the following:
- A system that keeps cutting out
- A noisy indoor or outdoor unit
- A fault code on the display
A photo of the error code and the unit’s rating label helps us plan the repair.

How we handle air conditioning repair in Farnham
We treat a faulty system the way a doctor treats a patient: diagnose the cause, treat it properly and sign it off when it’s working. Guesswork costs money, and topping up refrigerant on a system with a blocked filter fixes nothing. If you’re dealing with a noisy indoor or outdoor unit and a suspected refrigerant leak, we can sort it out.
Outdoor units in a place like Farnham can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Your questions about air conditioning repair in Farnham
Do you cover Farnham for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Farnham. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you cover Farnham for air conditioning repair?
Yes. Farnham is one of the places we cover. Just ring 07833 053749 or email us with a few details.
Why is my air conditioning blowing warm air?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which and you get a fixed price before the repair.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Why is my air conditioning leaking water?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and ring us on 07833 053749 or fill in the contact form.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.
What a repair looks like in Farnham
Historic England lists about 18 buildings and structures within half a mile of the centre of Farnham, including Globe Farmhouse (grade II). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed. About 30% of homes across Farnham and its surrounding area have been built since 2000, according to Valuation Office Agency council tax records. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
When cooling fails at a school like Farnham Church of England Primary School, we can time non-urgent repair work around lessons.

What owners can safely do
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
How the visit works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a single visit for many faults, while some repairs need a second visit once parts arrive, and we clear up before we go. Work in Farnham is booked in advance at a time that suits you.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- If the repair isn’t worth doing, we say so and explain the options.
- Then the fix, with leaks repaired before any refrigerant is added.
- Finally, a check that it’s working and a record of what we did.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Keep pets out of the rooms we are working in
- Arrange for someone to be there to let us in
Getting a price
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

What happens if it’s left?
A struggling system costs more to run. Poor airflow or low refrigerant means more running time for less effect and the extra work wears the parts faster. Small faults tend to grow, so it’s worth dealing with them early.
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
