How we handle air conditioning repair in Washington
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. The work covers wall-mounted split systems, VRF systems and ducted systems, and common reasons people get in touch are drips from the indoor unit and ice forming on the indoor unit or pipes.
We plan the trip to Washington so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

When to call us in Washington
Error codes are the system telling you it has found a fault. Each manufacturer uses its own codes, and the same code can have more than one cause, so we read the code and then test to confirm. Common causes include sensors, wiring between the units and the circuit boards.
If any of these sounds familiar, it’s worth a diagnosis:
- A unit that barely blows any air
- An error code or flashing light on the unit
- Frost on the pipework
If a system fails at a school such as St Mary's CofE Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
What to look for in a quote
- Whether anyone has checked the property or the system first
- Whether a new circuit is included and who certifies it
- Whether the quote is a fixed price

Air conditioning repairs in Washington: local notes
Central Washington is inside the Washington Conservation Area. The Parish Church of St Mary, listed at grade II*, is one of roughly 25 protected buildings and structures in the half-mile around Washington’s centre. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 84% of households live in detached or semi-detached houses, according to Census 2021 figures. If the outdoor unit is high up or behind a locked gate, mention it when you book.
The make, model and error code are the most useful things to tell us.

Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
The process
Every visit follows the same order: agree the plan on site, protect the area, do the work, test what we have done and talk you through it. The visit itself takes an hour or two to diagnose most faults, with the repair time depending on what we find. We plan the trip to Washington around you.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Prescribe: tell you the cause and the fixed cost of the cure.
- If the repair is not worth doing, we say so and explain the options.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Finally, a check that it’s working and a record of what we did.
Before we arrive
- Keep pets out of the rooms we are working in
- Let us know if the building has a permit or sign-in process
- Move furniture away from the wall where we will be working

Landlords, agents and facilities managers
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.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
