How we handle air conditioning servicing in Letchworth
An annual service is £95–£150 + VAT, and we confirm the figure before we book you in. Multi-split, ducted and commercial systems are priced once we know what’s there. Either way, you know the cost before the engineer arrives. The work covers wall-mounted split systems, ceiling cassettes and ducted systems, and common reasons people get in touch are leak check records that need bringing up to date and water dripping from the indoor unit.
Around Letchworth, we service home systems and business ones. Most homes only need a service once a year, more often for busy commercial systems.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Letchworth questions
Can I get a fixed-price quote for air conditioning servicing in Letchworth?
Send us photos of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Is Letchworth in your area for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Letchworth is part of that. Just phone 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
How long will you be on site?
We will confirm the time with your quote. As a guide, the work takes an hour or so for a single wall-mounted unit, longer for a multi-split system.
When is an F-gas leak check required?
The GOV.UK rules set leak checks at least every 12 months for 5 to under 50 tCO2e and every 6 months for 50 to under 500 tCO2e. Fitting leak detection lets you double the interval and we’ll confirm which band applies.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Can I have a maintenance contract for my air conditioning?
Yes, and the schedule is set around your system. We agree the cost up front, and each visit is recorded.
Will servicing keep my manufacturer’s warranty valid?
Warranty terms are set by the manufacturer, not by us. Read the conditions for your brand, as they may include servicing and file every service record.
What the work involves, system by system
Condensate drains and pumps
Some indoor units rely on a small pump to move the water. We check the pump runs and switches as it should since a stuck pump often means water from the unit.
Refrigerant performance and leak checks
We check how the refrigerant circuit is performing, using temperatures and pressures to see whether it’s working as it should. If the readings suggest gas has been lost, we explain what that means.
Looking after it afterwards
How well a system lasts depends on use and care. We suggest:
- Check what your manufacturer’s warranty asks of you
- File each service record with the manufacturer’s documents
- Check the condensate pipe outside isn’t blocked or crushed
After the service, you get a record of what was done, with the checks carried out and anything we’d recommend. Keep it with the manufacturer’s paperwork so the service history is in one place.
Cleaning the filters between services helps a great deal. On many wall-mounted units, the filters lift out easily and the user manual explains how often.

How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, which takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Access to the outdoor unit position is the main thing to tell us about in Letchworth.
- A date is fixed and the service price confirmed in advance.
- Before any cleaning, the system is run so we can see how it behaves.
- Filters, coils, fans and drains are cleaned and cleared.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- It’s run once more to confirm all is well, and the record is left with you.
How to prepare
- Tell us about any building rules, permits or sign-in
- Move furniture away from the wall where we’ll be working
- Let us know if the units are on a roof, a high wall or in a locked area
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.
