How we handle air conditioning servicing in Crabtree
For an annual service, the price is £95–£150 + VAT, and we confirm the figure before we book you in. Larger systems with several indoor units, ducted units or commercial plant are priced on their details. Either way, you know the cost before the engineer arrives. The work covers VRF systems, ducted systems and multi-split systems, and the jobs we see most are a unit showing a fault code and an unpleasant odour when the system runs.
We plan the trip to Crabtree and can service more than one unit in one visit, which keeps it simple.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Why deal with it now?
Smells from an indoor unit tend to come back each time it runs. The cure is cleaning where the dirt has built up instead of covering it up. Planning ahead for a job in Crabtree means we can bring everything needed.
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 explain each part.

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.
Keeping systems in Crabtree running
Census 2021 figures found about 78% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. The Crabtree Conservation Area is within about a third of a mile of the centre of Crabtree. Historic England lists about 6 buildings and structures within half a mile of the centre of Crabtree, including The Crabtree Inn (grade II). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
For a school like Newells Preparatory School, maintenance visits can be booked out of term.

Your questions about air conditioning servicing in Crabtree
Do you cover Crabtree for air conditioning servicing?
Yes, Crabtree is within the area we cover. Just give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
How often do you service systems in Crabtree?
Once a year suits most home systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Is a regas part of an air conditioning service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Adding gas without a repair just lets it leak away again, so we do not recommend it.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
What do you check on an air conditioning service?
Both the indoor and outdoor units are checked and cleaned: filters, coils, drains and fans, then the electrics, the controls and how the refrigerant circuit is performing. You get a record of the visit.
When to call us in Crabtree
Condensate has to drain away from every indoor unit. Sludge and debris can block the tray, the pipe or the pump and the result is drips from the indoor unit.
These are the situations we see most often:
- A musty or damp smell when the unit starts
- Leak check records that need bringing up to date
- Frost or ice on the refrigerant pipes
A service once a year suits most home systems, and some business systems need more.
Before booking anyone
- If the quote is based on a survey, photos or a diagnosis
- Whether the price is fixed or an estimate
- Proof of F-Gas company certification
What we do, step by step
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes anything from an hour for a simple split system to most of a day for a larger installation. We agree a date with you and plan the visit to Crabtree so we arrive with what’s needed.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- Anything we find is explained, with a fixed price if it needs a repair.
Getting ready for the visit
- Keep pets and children away from the work area
- Mention any managing agent or landlord rules we need to follow
- Arrange for someone to be there to let us in
