Does my air con in Welham Green need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Is Welham Green in your area for air conditioning servicing?

We clean the filters and coils, clear the condensate drain and check the fans. The electrics, controls and refrigerant circuit are tested too plus a leak check on systems that need one.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.

- Air-to-air heat pumps

Keeping the system healthy
Simple habits make a real difference. Our advice:
- Don’t wait for a small drip to become a leak
- Clear leaves and debris from around the outdoor unit
- Keep doors and windows closed while the system is cooling
When we finish, we leave a record of the visit, listing the work, the checks and any recommendations. Keep it with the manufacturer’s paperwork so the service history is in one place.
Book a service at least once a year with extra visits where the system runs constantly or needs more frequent leak checks.
Different systems, different jobs
Wall-mounted, ducted and cassette units
Ceiling cassettes are common in offices, shops and restaurants. The grille drops down for the filters, and the drain and pump are checked inside.
Refrigerant performance and leak checks
The engineer looks at how well the system is moving heat, using temperatures and pressures to see whether it’s working as it should. If something points to a leak, we tell you and set out the options.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
