- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Once the cause is found, we explain it and fix the price for the repair.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- The system is run and checked in every mode, and we tell you about anything else we noticed.

How to get a quote

Advice
Air conditioning repair in Northaw Valley
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If you’re dealing with a unit that barely blows any air and a unit that won’t start, we can help.
A visit to Northaw Valley is planned so we can typically finish in one go, though some parts have to be ordered from the manufacturer.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

For landlords and property managers
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements, and we’ll send a fixed-price quote.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.

What you can do yourself, and what needs us
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 the breaker trips a second time, leave it off and phone 07833 053749 or write to us at info@aircondoctor.co.uk.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Northaw Valley: your questions answered
Who do I call if my air conditioning fails in Northaw Valley out of hours?
Yes. Our 24/7 emergency line covers Northaw Valley. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Northaw Valley in your area for air conditioning repair?
Yes. Northaw Valley is one of the places we cover. Just phone us on 07833 053749 or fill in the contact form with a few details.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
What can I do with an old R22 system?
Servicing with new R22 is not allowed, because it depletes the ozone layer. A fault that does not involve the refrigerant may still be repairable, depending on parts, but a leak normally makes replacement the sensible route. We will set out the options and quote for a replacement where it makes sense.
How long will you be on site?
We will confirm the time with your quote. As a guide, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
