Air conditioning servicing in Radlett
People in Radlett book a service for all sorts of reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that’s overdue. The same full set of checks applies whatever prompted the call. If you’re dealing with error codes or flashing lights on the indoor unit and F-gas leak checks falling due, we can sort it out.
Outdoor units around Radlett tend to be close to gardens and hedges, which can clog the outdoor coil. Every service includes cleaning it.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

After we have gone
Looking after the system is mostly common sense. A few tips:
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Diary the next service before this one is forgotten
- Clear leaves and debris from around the outdoor unit
Any fault we find is explained, with a fixed price for the repair. Nothing extra is done without your say-so, so you stay in control of the cost.
Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than once the system has stopped.
Radlett: your questions answered
Will you come out to Radlett?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
How often should air conditioning in Radlett be serviced?
Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
What do you check on an air conditioning service?
We clean the filters and coils, clear the condensate drain and check the fans. The electrics, controls and refrigerant circuit are tested too plus a leak check on systems that need one.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Is a regas part of an air conditioning service?
A regas is a separate job, done once a leak has been found and fixed. Adding gas without a repair just lets it leak away again, so we don’t recommend it.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
What happens on the day
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes an hour or so for a single wall-mounted unit, longer for a multi-split system, and we clear up before we go. Because we plan from pictures or a survey, a job in Radlett can usually be finished in one visit.
- We start with the details of the system and anything you’ve noticed.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- Anything we find is explained, with a fixed price if it needs a repair.
Before we arrive
- Clear a path to the units and the space around them
- Make sure we can reach the consumer unit or fuse board
- Mention any roof access, ladders or high-level work

Different systems, different jobs
Condensate drains and pumps
Some indoor units rely on a small pump to move the water. The pump is tested to make sure it works, because a failed pump is a common reason for drips.
Indoor and outdoor coils
Coil fins are thin and easily flattened. We will point out damaged fins and whether they matter.

Fixed-price quotes for air conditioning servicing in Radlett
You’ll get a fixed price before work begins. It takes into account:
- The distance and route between the indoor and outdoor units
- Whether the existing supply is suitable
- The size of the job
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are unsure, phone 07833 053749, or email if that’s easier for straight advice and a fixed price.
