About our air conditioning servicing in Markyate
People in Markyate book a service for all sorts of reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. Whatever the reason, the visit follows the same thorough checks. The work covers wall-mounted split systems, ducted systems and air-to-air heat pumps, and common reasons people get in touch are air conditioning that isn’t cooling as well as it did and warning lights on the indoor unit.
For most homes near Markyate, a service once a year keeps the system efficient and the filters clean, and regular servicing can be a condition of some manufacturers’ warranties.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Air conditioning servicing around Markyate
About 28 miles out from central London, Markyate is part of the South East area we work across. The centre of Markyate lies within the Markyate Conservation Area. Historic England lists about 42 buildings and structures within half a mile of the centre of Markyate, including Church of St. John the Baptist (grade II*). If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
Spring is a good time for a service, before the system is needed for cooling. For a school like Markyate Village School and Nursery, maintenance visits can be booked out of term.

How it works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. A few photos let us plan a visit to a place like Markyate.
- First we take the details: brand, model if you have it, how many indoor units and anything that is been bothering you.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Filters, coils and the condensate drain are cleaned and cleared.
- The wiring, controls and refrigerant performance are checked, plus a leak check on systems large enough to need one.
- We leave you a record of the service and explain anything we found.
How to prepare
- Unlock any gate, garage or side passage we need
- Let us know where we can park and unload
- Find the manual or the paperwork for the system, if you have it

Advice

Controls and remote handsets are tested in each mode so you know it does what you ask.
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.
FAQs for Markyate
Do you cover smaller places like Markyate?
Yes. Markyate is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
How often should air conditioning in Markyate be serviced?
Usually once a year for homes, more often for busy business systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Will you work on another installer’s system?
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.
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. Tell us the make and model and we’ll take it from there.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
How much time does an air con service need?
It takes a short visit for one split system, longer for multi-split, ducted or commercial plant. The number of indoor units and how easy they are to reach make the biggest difference, and we’ll give you an idea when we book.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
