Knaphill questions
Do you cover smaller places like Knaphill?
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 Knaphill for air conditioning servicing?
Yes, Knaphill is within the area we cover. To start, phone 07833 053749 or drop us a line with a few photos.
Will you regas my air conditioning on a service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Topping up without finding the leak means the gas escapes again and that is money wasted.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
How it works
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Getting to the outside of the property matters more than parking in a place like Knaphill.
- You tell us the brand, the number of indoor units and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays 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 out of the rooms we’re working in
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
Getting a quote
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, call us on 07833 053749.

When it’s something else
Some problems need a different service or another trade:
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
- A failed compressor, fan motor or circuit board, which needs a repair
- Poor original installation, such as drains without a proper fall
If in doubt, phone 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll say what we think.

- Frost or ice on the refrigerant pipes
- Condensate leaking into the room
