How we handle air conditioning servicing in Longfield
People in Longfield 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. The work covers air-to-air heat pumps, wall-mounted split systems and ceiling cassettes, and people most often call us about frost or ice on the refrigerant pipes and no service record for the last year or more.
For a home in or near Longfield, a service once a year suits most systems, best done before summer.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

System by system
Refrigerant performance and leak checks
The law requires leak checks once a system reaches 5 tCO2e: at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e doesn’t need them.
Maintenance contracts
We tailor the schedule to how hard the system works so it fits your site.
What air conditioning will not do
It’s worth knowing the limits before booking:
- A system short of gas because of a leak
- Installation faults that need reworking
- A system that is too small for the room it serves
If you are not sure, just call 07833 053749 or fill in the contact form and we will give you a straight answer.

Questions from Longfield
Is Longfield within the area you cover?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Longfield for air conditioning servicing?
We do: Longfield falls inside our working area. Tell us a little about the job and we will take it from there.
Do I need a service to keep the manufacturer’s warranty?
The answer is in your manufacturer’s warranty conditions. If servicing is required, a regular service record is the evidence, and we can explain what your brand asks for.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
What happens on the day
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, test what we have done and explain it all to you. The visit itself takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. If a lane or gateway near Longfield is tight for a van, let us know and we will plan for it.
- We book a time that suits you and confirm the price.
- The engineer runs the system and checks how it’s performing.
- 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.
Getting ready for the visit
- Keep pets out of the rooms we’re working in
- Clear a path to the units and the space around them
- Clear access to the fuse board

Looking after it afterwards
Systems last better with the right care. Here’s what we suggest:
- Diary the next service before this one is forgotten
- Keep the drain outlet clear
- Read the warranty conditions for your brand
Where the system needs F-gas leak checks, the result is recorded and the next one falls due within 6 or 12 months, depending on the system. We can book it in ahead of time.
Make sure condensate pipes outside aren’t crushed, blocked or buried. A pipe that is been knocked or covered can back up into the indoor unit.
