Aftercare tips

Looking after the system is mostly common sense. Our tips:

  • Know your manufacturer’s servicing conditions
  • Rinse the indoor unit filters every few weeks when the system is in heavy use
  • Leave space around the outdoor unit for air to flow

The best time to book the next service is now, while you remember. Many people book in spring, before the cooling season, or in autumn if they use the system for heating although we service all year round.

Cleaning the filters between services helps a great deal. Most indoor units have filters you can slide out and rinse, and the manual shows how.

Air conditioning servicing for homes and businesses in Keymer

Maintenance contracts suit anyone who would rather not have to remember when the next service is due. We agree the visits, what each one covers and the price with your quote, so the system is looked after on a regular schedule. We’re often asked to deal with systems that haven’t been serviced for a while and condensate leaking into the room, across ducted systems, wall-mounted split systems and VRF systems.

We book services in Keymer at a time that suits you, and most single systems take an hour or two.

Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

How the job changes from property to property

Filters

A clogged filter cuts the airflow through the unit. The room takes longer to get comfortable so cleaning them is one of the first jobs.

Indoor and outdoor coils

The indoor coil is where the air is cooled or warmed. Cleaning removes the dust that coats the fins and any damage is noted.

How it works

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Photos of the existing unit and its label help with repairs and servicing near Keymer.

  1. A date is fixed and the service price confirmed in advance.
  2. The engineer runs the system and checks how it’s performing.
  3. Filters, coils, fans and drains are cleaned and cleared.
  4. The electrics, controls and refrigerant performance are checked, with a leak check where required.
  5. We run the system again and leave you a service record.

Before we arrive

  • Make sure someone can let us in at the agreed time

Keymer questions

How often do you service systems in Keymer?

Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.

Do you cover smaller places like Keymer?

Yes. Keymer is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.

Can I have a maintenance contract for my air conditioning?

Yes, with visits planned to suit how hard the system works. The price is fixed with your quote, and each visit is recorded.

Is there a survey before the work?

Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.

What do you check on an air conditioning service?

Both the indoor and outdoor units are checked and cleaned: the filters, coils, drain and fans, followed by the wiring, controls and refrigerant performance. You get a record of the visit.

When is an F-gas leak check required?

The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems holding less than 10 tCO2e don’t need them.

Do you have a 24/7 line?

Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.

  • A refrigerant leak, which needs finding and repairing, not topping up
