Air conditioning servicing across Slough

Aftercare tips

Simple habits make a real difference. Our advice:

  • Make sure the condensate outlet can drain
  • Shut doors to the room so the system is not cooling the whole house
  • Keep the service records with the warranty paperwork

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, though any time of year works.

Book a service at least once a year with extra visits where the system runs constantly or needs more frequent leak checks.

Air conditioning servicing for homes and businesses in Slough

For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Multi-split, ducted and commercial systems are priced once we know what’s there. There’s no guessing at the bill afterwards. Common call-outs are for air conditioning that isn’t cooling as well as it did and warning lights on the indoor unit, across air-to-air heat pumps, wall-mounted split systems and VRF systems.

In a place the size of Slough, we service home systems, offices, shops and restaurants. A service cleans the filters and coils, clears the drain, checks the refrigerant circuit and electrics, and tests the system.

Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Slough: your questions answered

Do you cover Slough for air conditioning servicing?

We do: Slough falls inside our working area. To start, phone 07833 053749 with a few pictures.

How often should air conditioning in Slough be serviced?

A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.

How long does an air conditioning service take?

Expect it to take an hour or so for a single wall-mounted unit, longer for a multi-split system. The number of indoor units and how easy they are to reach make the biggest difference so we’ll confirm the time when we book.

Do you offer maintenance contracts?

Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.

Can you look at a system you didn’t fit?

Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

What does F-Gas certified mean?

Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and we hold it.

Will I get records for the system?

Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.

What a service looks like in Slough

Listed buildings are part of the picture here: about 12 within half a mile of the centre, such as Church of St Peter (grade II*). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. The Valuation Office Agency’s council tax figures show about 34% of homes across Slough and its surrounding area were built in 2000 or later. Access to the outdoor unit is the one detail that most changes how a visit is planned.

If you look after a school such as Herschel Grammar School, servicing is easiest in the holidays.

For landlords and property managers

We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.

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.

The process

The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. For a visit in Slough, let us know where we can park and how to reach the outdoor unit.

  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. We clean the filters, coils and fans and clear the condensate drain.
  4. Electrical and refrigerant checks follow, including a leak check if the rules require one.
  5. It’s run once more to confirm all is well, and the record is left with you.

Before we arrive

  • Plan for pets to be kept clear during the visit
  • Make sure we can reach the consumer unit or fuse board
  • Have the make and model of any existing unit to hand

When to call us in Slough

Small refrigerant leaks don’t announce themselves. The system just cools or heats a little less well each year, until it cannot keep up on the hottest or coldest days.

The things we are asked about most are:

  • Ice forming on the pipework or outdoor unit
  • Drips or damp patches below an indoor unit
  • A system that struggles to cool on warm days

Businesses close to Slough station can book an early or late slot so the service doesn’t get in the way of trade.

What your quote should include

  • Whether they looked at the job before pricing it
  • How VAT is shown, and which rate applies
  • Whether the electrical work is done by a registered contractor, such as NICEIC approved
