Smallford: your questions answered
Is Smallford within the area you cover?
Yes. Smallford is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Smallford for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Smallford is part of that. To start, ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few pictures.
Can you come out in an emergency?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
What do you check on an air conditioning service?
A clean of the parts that collect dirt and a check of the parts that do the work. Filters, coils and drains are cleaned, and the electrics, controls and refrigerant circuit checked, and F-gas leak checks where they apply.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking and we will gladly show you ours.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
About our air conditioning servicing in Smallford
People in Smallford book a service for all sorts of reasons: a musty smell, weak cooling, water dripping indoors or simply because it’s been a while. Whatever the reason, the visit follows the same thorough checks. We are often asked to deal with iced-up coils or pipework and water dripping from the indoor unit, on VRF systems, ceiling cassettes and multi-split systems.
We plan the trip to Smallford and can service more than one unit in one visit.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What happens if it’s left?
Drainage problems tend to grow. What starts as a damp patch under the indoor unit can become water running down the wall, which is easily avoided by clearing the drain on a service. Dealing with it now is typically simpler than a breakdown later.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll go through it with you.

What we do, step by step
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes an hour or so for a single wall-mounted unit, longer for a multi-split system, and we tidy up before we leave. A few pictures help us make the most of a visit to Smallford.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- We run the system again and leave you a service record.
How to prepare
- Keep pets out of the rooms we are working in
- Let us know where the consumer unit is
- Mention any parking restrictions near the property

Different systems, different jobs
Fans and electrics
Controls and remote handsets are tested in each mode to make sure the system responds properly.
Refrigerant performance and leak checks
To find tCO2e, multiply the kg of refrigerant by its GWP and divide by 1,000. So 3 kg of R32 is roughly 2.0 tCO2e, and the same amount of R410A is roughly 6.3 tCO2e. We read the charge from the unit’s label and work it out for you.

Common problems we fix in Smallford
Electrical terminals can work loose as the system heats, cools and vibrates. That can lead to intermittent faults, so the engineer checks them as part of the service.
Reasons to give us a call include:
- Frost or ice on the refrigerant pipes
- A unit showing a fault code
- Weaker cooling than last year
If you look after a school such as Nicholas Breakspear Catholic School, servicing is easiest in the holidays.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether testing, commissioning and paperwork are included
- How extra work would be agreed if they find something unexpected
