About our air conditioning servicing in Colgate
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. Each brand sets its own terms and we are happy to go through them with you. Our service record shows the work was done. We’re often asked to deal with warning lights on the indoor unit and smells coming from the indoor unit, on wall-mounted split systems, multi-split systems and air-to-air heat pumps.
Most systems around Colgate need servicing once a year, best done before summer.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. 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.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Managing agents and facilities teams in Colgate
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Common questions in Colgate
How often do you service systems in Colgate?
A yearly visit is right for most households. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you cover Colgate for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Colgate is part of that. Just call us on 07833 053749 or drop us a line with a few details.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
Is an F-gas leak check a legal requirement for my system?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Are you F-Gas certified?
We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Looking after it afterwards
Every system needs looking after, and most of it is easy. Our tips:
- Check the condensate pipe outside isn’t blocked or crushed
- Read the warranty conditions for your brand
- Rinse the indoor unit filters every few weeks when the system is in heavy use
Any fault we find is explained, with a fixed price for the repair. We do not carry out extra work until you’ve agreed it and the decision is always yours.
The single most useful thing you can do is keep the filters clean. Most indoor units have filters you can slide out and rinse and the user manual explains how often.
Keeping systems in Colgate running
VOA council tax data show about 42% of homes across Colgate and its surrounding area were built in 2000 or later. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. Colgate is about 30 miles from central London, well within the area we cover from our base in East Grinstead.
If you look after a school such as Colgate Primary School, servicing is easiest in the holidays. Booking before the first hot spell means the system is ready when you need it.

What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a short visit for one split system, longer for multi-split, ducted or commercial plant. A few pictures help us make the most of a visit to Colgate.
- First, we agree a time and confirm the cost of the service.
- Before any cleaning, the system is run so we can see how it behaves.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- It’s run once more to confirm all is well, and the record is left with you.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Keep pets and children away from the work area
- Dig out any previous service or F-Gas records

Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
