Air conditioning servicing for homes and businesses in Northaw Valley
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that is short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. We are often asked to deal with F-gas leak checks falling due and an unpleasant odour when the system runs, on multi-split systems, ceiling cassettes and VRF systems.
Several units at a home near Northaw Valley can be serviced in one visit.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Why act early in Northaw Valley
For most systems at or over 5 tCO2e, leak checks are a legal requirement, not a choice. Skipping a year leaves a gap in the records the rules expect you to keep, and it’s simpler to keep to the schedule. A system that’s left with a fault, or without a service, typically costs more to run.
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.

What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. 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.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749 or drop us a line.
Keeping the system healthy
After the visit, a few habits help:
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Report drips, smells or noises early
- Keep plants, bins and stored items away from the outdoor unit
For systems that need them, the leak check and its result go on record and the next one falls due within 6 or 12 months, depending on the system. We can diary it for you.
Cleaning the filters between services helps a great deal. Most indoor units have filters you can slide out and rinse and the user manual explains how often.
