How we handle air conditioning repair in Portchester
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. The work covers multi-split systems, wall-mounted split systems and ducted systems, and people most often call us about new noises from the system and a unit blowing warm air.
Outdoor units around Portchester often sit near hedges, trees and lawns, and leaves or grass cuttings on the coil are a common reason for poor cooling. We check the coil early on.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Keeping the system healthy
So the system stays in good health:
- Stop the unit if water is coming through a ceiling
- Ask for the leak to be found, not just a top-up
- Turn it off and let ice clear before the visit
Where a repair isn’t worth doing, we say so, and explain why. If replacement is the better option, we can quote for it on the same visit.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.
What air conditioning will not do
In fairness, some problems need a different answer:
- An R22 system that has lost its refrigerant
- Heat gains the system was never designed for
- A supply fault outside the property
If in doubt, phone us on 07833 053749 or fill in the contact form and we will say what we think before booking.

What a repair looks like in Portchester
The coast is only about 1 mile from Portchester. Coastal outdoor units can suffer from corroded coils and terminals, which can lead to poor cooling or trips. About 34% of homes across Portchester and its surrounding area were built between the wars, according to VOA council tax data. If the outdoor unit is high up or behind a locked gate, mention it when you book. The middle of Portchester is part of the Portchester (Castle Street) Conservation Area. Church of St Mary, listed at grade I, is one of roughly 54 protected buildings and structures in the half-mile around Portchester’s centre. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.

Your questions about air conditioning repair in Portchester
Will you come out to Portchester?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is there an emergency air con repair line for Portchester?
Yes. Our 24/7 emergency line covers Portchester. Have the make, model and error code ready, and we will talk you through what happens next.
Why is my air conditioning icing up?
It normally points to poor airflow or a refrigerant leak. Blocked filters, a failing fan or a leak are the common causes. Switch the system off, let it thaw and give us a ring on 07833 053749 or email us.
Which brands do you work with?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Can you repair an R22 air conditioning system?
Servicing with new R22 is not allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a leak usually makes replacement the sensible route. We’ll set out the options and quote for a replacement where it makes sense.
Why is my air conditioning showing a fault code?
The code is the system’s own clue to the fault, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and phone 07833 053749 or use the quote form.
How it works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Visits to a place like Portchester are planned ahead, so we arrive with what the job needs.
- Describe the problem and the brand, and mention any code on the display.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- The system is run and checked, and you get a written note of the repair.
Preparing for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any parking restrictions near the property
- Keep pets and children away from the work area
