About our air conditioning servicing in Lower Sheering
Maintenance contracts suit anyone who would rather not have to remember when the next service is due. We agree the visits, what each one covers and the price with your quote, so the system is looked after on a regular schedule. If the problem is no service record for the last year or more and drips or damp patches below an indoor unit, we can help.
Around Lower Sheering, outdoor units sit close to gardens and greenery, so leaves, seeds and cobwebs collect on the coil. A yearly clean keeps the system working well.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. 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 a short visit for one split system, longer for multi-split, ducted or commercial plant. Work in Lower Sheering is booked in advance at a time that suits you.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- If a repair is needed, you hear why and what it costs before anything is done.
Getting ready for the visit
- Plan for pets to be kept clear during the visit
- Have the make and model of any existing unit to hand
- Move furniture away from the wall where we’ll be working
Getting a price
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

How the job changes from property to property
Wall-mounted, ducted and cassette units
Cassette units are set into the ceiling and blow air in several directions. We drop the grille to clean the filters and check the condensate pump.
Refrigerant performance and leak checks
We check how the refrigerant circuit is performing, checking temperatures and pressures against what the system should achieve. If the readings suggest gas has been lost, we explain what that means.

Is Lower Sheering in your area for air conditioning servicing?
We do: Lower Sheering falls inside our working area. Tell us a little about the job and we’ll take it from there.
Will I get records for the system?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Which brands do you work with?
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.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
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. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

Why deal with it now?
A dirty filter or coil makes the system work harder for the same result. A service puts that right with a clean and lets the system run as it was designed to. Dealing with it now is typically simpler than a breakdown later.
