When to call us in Letchmore Heath

When the system cools, water condenses on the indoor coil. That moisture traps dust, and a dirty coil and drain tray are a common source of musty smells.

Customers normally contact us after spotting something like this:

  • Condensate leaking into the room
  • Iced-up coils or pipework
  • No service record for the last year or more

If you can’t remember the last service, it’s probably due.

Before booking anyone

  • Proof of F-Gas company certification
  • What paperwork you will receive afterwards
  • Whether the quote is a fixed price

How we handle air conditioning servicing in Letchmore Heath

Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. If the problem is a unit showing a fault code and smells coming from the indoor unit, we can help.

Most systems around Letchmore Heath need servicing once a year, best done before summer.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

When it’s something else

To be straight with you, some problems need a different answer:

  • Rooms that gain heat faster than any unit could cope with
  • Pipework or drainage that was badly installed in the first place
  • A system short of gas because of a leak

If in doubt, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll say what we think before you book.

Parts of the system we cover

  • Air-to-air heat pumps
  • Wall-mounted split systems
  • Multi-split systems
  • VRF systems
  • Ceiling cassettes
  • Ducted systems

Looking after your system

So the system stays in good health:

  • Shut doors to the room so the system isn’t cooling the whole house
  • Read the warranty conditions for your brand
  • Make sure the condensate outlet can drain

If we find a fault, we explain it and give you a price to put it right. Nothing extra is done without your say-so and the decision is always yours.

Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than after a breakdown.

What happens on the day

We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. A note on how to find the property and where to park makes a visit to Letchmore Heath easier.

  1. We start with the details of the system and anything you’ve noticed.
  2. The indoor units are opened up and the filters, coils and drain trays cleaned.
  3. The outdoor unit is cleaned and checked, and debris cleared from around it.
  4. We test the electrics, the controls and how the refrigerant circuit is performing.
  5. Anything we find is explained, with a fixed price if it needs a repair.

Before we arrive

  • Mention any parking restrictions near the property
  • Keep pets out of the rooms we’re working in
  • Clear access to the fuse board

FAQs for Letchmore Heath

How often do you service systems in Letchmore Heath?

A yearly visit is right for most households. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.

Is Letchmore Heath in your area for air conditioning servicing?

Yes. We work across London and the South East from our base in East Grinstead, and Letchmore Heath is part of that. To start, ring 07833 053749 or fill in the contact form with a few photos.

When is an F-gas leak check required?

The requirement starts at 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We read the charge from the label and work it out for you.

What do you check on an air conditioning service?

We clean the filters and coils, clear the condensate drain and check the fans. The electrics, controls and refrigerant circuit are tested too, with an F-gas leak check where the system requires one.

Can I do any of the installation myself?

The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.

When will I hear back?

The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.

Will you make a mess?

We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
