Air conditioning repair in North Wembley

After we have gone

Every system needs looking after, and most of it is easy. Our tips:

  • Book an annual service after the repair
  • Let any ice thaw before the engineer arrives
  • Only let an F-Gas qualified engineer work on the refrigerant

You get a note of the fault and what we did: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.

Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs and the system does not have to work as hard.

Air conditioning repair in North Wembley, done properly

For breakdowns that can’t wait, there’s a 24/7 emergency line, from an overheating comms room to water leaking from a unit. Ring 07833 053749 with the make, what’s happening and any code and we will talk you through what happens next. If you are dealing with water leaking from the unit or through the ceiling and a unit that barely blows any air, we can sort it out.

London systems in North Wembley often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.

Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

When it’s something else

Not every problem is solved by air conditioning repair, and we’ll tell you before we start. It doesn’t solve:

  • A discontinued model with no parts available
  • A supply fault outside the property
  • A system that was undersized for the room in the first place (that needs a bigger system, not a repair)

If in doubt, phone us on 07833 053749 or send an email and we’ll say what we think before booking.

What the work covers

  • VRF systems
  • Wall-mounted split systems
  • Heat pumps
  • Ducted systems
  • Ceiling cassettes
  • Multi-split systems

Different systems, different jobs

Condensate drains and pumps

Most water leaks from indoor units come back to the condensate system. Blockages, kinks and failed pumps are the usual causes, and a unit that has dropped out of level can leak.

Refrigerant leaks

Topping up without finding the leak only delays the next breakdown and the gas simply leaks out again. That is why we repair the leak first.

When air con fails in North Wembley

About 39% of homes in and around North Wembley were built between the wars, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 47% of households live in flats. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. London repairs often depend on reaching the outdoor unit, so access details help us plan. Central North Wembley is inside a conservation area. There are 2 conservation areas within a mile of the centre of North Wembley. Historic England lists about 5 buildings and structures within half a mile of the centre of North Wembley, including Church of St John (grade II). Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.

Near Wembley Central station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair. Schools such as Park Lane Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

Common questions in North Wembley

Can you do air conditioning repair in North Wembley?

Yes. North Wembley is one of the places we cover. Get in touch with the details and we reply the same working day.

Do you cover North Wembley for emergency air conditioning repairs?

The emergency line is open around the clock, and North Wembley is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.

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

Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.

Why is my air conditioning leaking water?

Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and give us a ring on 07833 053749 or send an email.

Is it legal to repair an R410A system?

Yes. Repairing and recharging existing R410A systems is still legal. R410A is getting scarcer and dearer to buy as the GB phase-down tightens, so for older systems we compare the cost of a repair with a replacement.

Are you F-Gas certified?

As the law requires for refrigerant work, we’re an F-Gas certified company. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.

Whose job is it to check the system for leaks?

The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

The process

On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. In a London area like North Wembley, parking and access are worth sorting out before the day.

  1. You tell us the symptoms, the make and any error code.
  2. A diagnosis visit finds the cause with proper tests.
  3. We explain the cause in plain English and give you a fixed price.
  4. With your go-ahead, we carry out the repair, recording any refrigerant work.
  5. We test the system in operation and leave you a note of the fault and the fix.

How to prepare

  • Have the make and model of any existing unit to hand
  • Let us know where the consumer unit is
  • Arrange for someone to be there to let us in
