Air conditioning servicing for homes and businesses in Holwellbury
Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Dust, fluff and anything else in the air ends up on those parts. Servicing removes it, letting air pass through the unit properly and the condensate drain away. Common call-outs are for frost or ice on the refrigerant pipes and no service record for the last year or more, on multi-split systems, ceiling cassettes and ducted systems.
We plan the trip to Holwellbury and can service more than one unit in one visit, which keeps it simple.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Do you need air conditioning servicing in Holwellbury?
A slow leak can go unnoticed for a long time. The system just cools or heats a little less well each year and only becomes obvious when the weather is at its extreme.
If any of these sounds familiar, it’s worth a diagnosis:
- Frost or ice on the refrigerant pipes
- Systems that need a 6 or 12-monthly leak check
- Air conditioning that is not cooling as well as it did
If you look after a school such as Derwent Lower School, servicing is easiest in the holidays.

One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. You’ll have a fixed price before any work starts, with VAT shown clearly.

How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Photos of the existing unit help with repairs and servicing in Holwellbury.
- It begins with a few questions about the make, the rooms served and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
Preparing for the visit
- Let us know where the consumer unit is
- Name a contact who can meet us at the agreed time
- Move furniture away from the wall where we will be working

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Refrigerant performance and leak checks
F-gas leak checks are required for systems from 5 tCO2e upwards: 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.
Holwellbury questions
Will you come out to Holwellbury?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
How often do you service systems in Holwellbury?
Normally once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Does my air conditioning need an F-gas leak check?
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. With leak detection fitted, the interval can be doubled and we will confirm which band applies.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Which manufacturers do you install and repair?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
