About our air conditioning servicing in Longford
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We carry out air conditioning servicing for homes and businesses in Longford and the rest of Slough, for most leading brands. If you’re dealing with error codes or flashing lights on the indoor unit and new noises from the indoor or outdoor unit, we can help.
For a home in or near Longford, a service once a year suits most systems, ideally in spring before the warm weather.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What air conditioning servicing cannot fix
Air conditioning servicing can’t fix everything, and we will tell you before any work starts. It doesn’t solve:

- Installation faults that need reworking
- Cooling capacity that doesn’t match the space
If you’re not sure, just phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you a straight answer before you book.

Common questions in Longford
How often do you service systems in Longford?
Normally once a year for homes, more often for busy business systems. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Can you do air conditioning servicing in Longford?
We do: Longford falls inside our working area. Get in touch with the details and we reply the same working day.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Will you regas my air conditioning on a service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
Can you come out in an emergency?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Are you F-Gas certified?
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.

Businesses close to Heathrow Terminal 5 Rail station can book an early or late slot so the service doesn’t get in the way of trade. For a school like Pippins School, maintenance visits can be booked out of term.

What you can do yourself, and what needs us
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What affects the quote in Longford
Typical ranges are on our prices page, and your quote is built on your job. The quote depends on:
- What we find on the survey or diagnosis
- Whether it’s a simple split or a larger system
- The electrical supply and whether a new circuit is needed
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- Any previous service or F-Gas records
- The address and the type of property
- The outdoor side of the property, including any roof or flat area
To get a fixed-price quote, ring 07833 053749 or write to us at info@aircondoctor.co.uk with the address and a few details about the rooms or units involved. A few photos make it quicker. You will hear back from us the same working day.
