About our air conditioning servicing in Letty Green
For homes with one or two units and businesses with many, we can set up a maintenance contract. The visits, the scope and the cost are fixed with your quote, so the system is looked after on a regular schedule. If the problem is smells coming from the indoor unit and iced-up coils or pipework, we can sort it out.
Most systems around Letty Green 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. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Air conditioning servicing around Letty Green
Letty Green is about 20 miles from central London, well within the area we cover from our base in East Grinstead. Historic England lists about 7 buildings and structures within half a mile of the centre of Letty Green, including Munn's Farm House (grade II). That only matters for replacements, where a new outdoor unit on a protected building can need consent.
If you cannot remember the last service, it’s probably due. If you look after a school such as Hertingfordbury Cowper Primary School, servicing is easiest in the holidays.

Different systems, different jobs
Fans and electrics
We test the controls, the modes and the timers so you know it does what you ask.
Filters
A clogged filter cuts the airflow through the unit. That makes it harder for the system to reach the temperature you’ve set so cleaning them is one of the first jobs.

Letty Green: your questions answered
How often should air conditioning in Letty Green be serviced?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Do you cover Letty Green for air conditioning servicing?
Yes, Letty Green is within the area we cover. To start, give us a ring on 07833 053749 or fill in the contact form with a few photos.
Can I have a maintenance contract for my air conditioning?
We do, for one unit at home or many across a site. We fix the schedule, the scope and the cost with your quote and the servicing happens on time.
Do you work on all makes?
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’ll take it from there.
How long will the engineer be here for the service?
A typical service takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Ducted units in ceiling voids and outdoor units in awkward places can add time, and we will tell you in advance.
Does my air conditioning need an F-gas leak check?
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.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Keeping the system healthy
Simple habits make a real difference. We recommend:
- Keep plants, bins and stored items away from the outdoor unit
- Keep the filters clean between visits
- Close windows when the air conditioning is running
Any fault we find is explained, with a fixed price for the repair. Nothing extra is done without your say-so, so you stay in control of the cost.
Don’t ignore small changes. Odd noises, smells and drips are cheaper to sort out before they grow than after a breakdown.
What happens on the day
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Somewhere like Letty Green, it helps to know about lanes, gates and where to park.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- We run the system first and see how it’s performing.
- 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.
- A service record follows, with any faults and the options for fixing them.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the units are on a roof, a high wall or in a locked area
- Keep pets and children away from the work area
