Every service follows a thorough checklist, so nothing is missed and your system is left clean, safe and running efficiently.
We remove, clean and refit the filters to restore airflow and air quality.
Indoor and outdoor coils are cleaned so the system can transfer heat efficiently.
We treat the indoor unit to help remove mould, bacteria and unpleasant smells.
We clear the drain line and test any condensate pump to prevent water leaks.
We check operating pressures and look for signs of refrigerant leaks.
We inspect wiring, connections and controls for wear, damage or loose terminals.
We check fans, motors and moving parts for noise, wear and balance.
We measure air temperatures and test heating and cooling modes, then report back.
Dust, dirt and bacteria build up inside every air conditioning system over time. Without regular cleaning, the system has to work harder, uses more energy and is more likely to break down when you need it most.
Many manufacturers, including Mitsubishi Heavy Industries and Daikin, also expect systems to be serviced regularly to keep the warranty valid.
A clean, well-maintained system uses less energy to heat and cool.
We spot worn parts and small faults before they become costly repairs.
Clean filters and coils help reduce dust, allergens and odours.
From a single wall-mounted unit to a full office system, we service and maintain air conditioning of every size.
An annual service keeps your home system quiet, efficient and ready for summer and winter. We work cleanly and explain everything we find.
Keep staff, customers and equipment comfortable with planned maintenance. We offer maintenance contracts for businesses, scheduled around your opening hours.
The right service interval depends on how often your system runs and whether it is in a home or a business.
For most homes, one service a year is enough to keep your system clean, efficient and reliable. Spring is ideal, so your system is ready for summer.
Commercial systems usually work harder and need more frequent maintenance. Under UK F-Gas rules, systems above 5 tonnes CO₂ equivalent of refrigerant must also be leak checked by a qualified engineer:
Our maintenance contracts cover regular servicing and the checks your system needs.
Spotted any of these? It is time to book a service before a small issue becomes a breakdown.
Less air coming from the indoor unit usually means blocked filters or dirty coils.
If rooms take longer to reach temperature, the system may need cleaning or a refrigerant check.
Unpleasant smells point to mould and bacteria building up inside the unit.
A dirty system has to work harder, which can push up your electricity costs.
Rattles, buzzing or dripping water are early signs that something needs attention.

Answers to the questions we are asked most about air conditioning servicing and maintenance.
Most home systems should be serviced at least once a year. Systems that run most days, and commercial systems, usually need servicing every 6 months or as part of a planned maintenance contract.
Our service includes cleaning filters and coils, an antibacterial treatment, drain and condensate checks, refrigerant pressure checks, electrical safety checks, a fan and motor inspection and a full performance test.
A service on a single wall-mounted system usually takes around an hour. Larger multi-split, ducted or commercial systems take longer, and we will give you a time estimate when you book.
For most home systems it is not a legal requirement, but it is strongly recommended. For systems above 5 tonnes CO₂ equivalent of refrigerant, UK F-Gas rules require regular leak checks by a qualified engineer.
Many manufacturers, including Mitsubishi Heavy Industries and Daikin, expect systems to be serviced regularly. Check your warranty terms, and we will keep a record of every service we carry out.
