About our air conditioning servicing in Marks Gate
Maintenance contracts suit anyone who would rather not have to remember when the next service is due. The visits, the scope and the cost are fixed with your quote, so the system is looked after on a regular schedule. The work covers ducted systems, ceiling cassettes and multi-split systems, and common reasons people get in touch are new noises from the indoor or outdoor unit and an unpleasant odour when the system runs.
For a home in or near Marks Gate, a service once a year suits most systems, ideally in spring before the warm weather.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Marks Gate questions
Is Marks Gate in your area for air conditioning servicing?
Yes, Marks Gate is within the area we cover. To start, call 07833 053749 or fill in the contact form with a few pictures.
How often should air conditioning in Marks Gate be serviced?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Is an F-gas leak check a legal requirement for my system?
Under GOV.UK guidance, systems of 5 to under 50 tCO2e need a check at least every 12 months, and 50 to under 500 tCO2e every 6 months. With leak detection fitted, the interval can be doubled and we will confirm which band applies.
How long will the engineer be here for the service?
As a guide, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Units that are hard to reach can take longer and we’ll let you know before the visit.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Which accreditations do you hold?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
What does an air con service involve?
The service covers the indoor units and the outdoor unit: the filters, coils, drain and fans, followed by the wiring, controls and refrigerant performance. You get a record of the visit.
Rented and managed buildings
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.

Keeping the system healthy
Once we have finished, these simple steps help:
- Keep doors and windows closed while the system is cooling
- File each service record with the manufacturer’s documents
- Keep the drain outlet clear
If we find a fault, we explain it and give you a price to put it right. Nothing extra is done without your say-so and the decision is always yours.
An annual service is the simplest routine to keep to, and more often if the system works hard or the rules require it.
The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Rural lanes and tight entrances are worth mentioning before a visit to Marks Gate.
- First we take the details: brand, model if you have it, how many indoor units and anything that’s been bothering you.
- We run the system first and see how it’s performing.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Next come the terminals, the controller and the refrigerant side, with a leak check if the system’s size makes one a legal duty.
- You get a service record, with anything that needs attention explained.
Getting ready for the visit
- Move furniture away from the wall where we’ll be working
- Mention any roof access, ladders or high-level work
- Mention any parking restrictions near the property

Advice
Keeping systems in Marks Gate running
The Valuation Office Agency’s council tax figures date about 62% of homes in and around Marks Gate to the post-war years, 1945 to 1972. If the outdoor unit is high up or behind a locked gate, mention it when you book. On the National Heritage List, around 7 entries fall within 0.5 miles of the middle of Marks Gate; The White House (grade II) is one. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Booking before the first hot spell means the system is ready when you need it. For a school like Crownfield Infant School, maintenance visits can be booked out of term.
