Air conditioning repair in Pegsdon
Refrigerant doesn’t get used up, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. If the problem is new noises from the system and ice on the pipework or the coil, we can help.
Around Pegsdon, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Different systems, different jobs
Condensate drains and pumps
We clear the drain, test the pump and check the fall, so the water goes where it should. Failed pumps are replaced and test it before we leave.
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling and access is part of the job. Many have condensate pumps, and pump failures are a common cause of ceiling leaks.
Questions from Pegsdon
Who do I call if my air conditioning fails in Pegsdon out of hours?
The emergency line is open around the clock, and Pegsdon is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you cover smaller places like Pegsdon?
Yes. Pegsdon is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and phone us on 07833 053749 or send an email.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Pegsdon and across Hertfordshire. Tell us who should receive the paperwork.
Why is my air conditioning showing a fault code?
The code is the system’s own clue to the fault, but it is not the whole answer. Note the code and switch the system off if it isn’t working, then ring 07833 053749 or write to us at info@aircondoctor.co.uk.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the room and the outside of the property help us plan a visit to Pegsdon.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Before we arrive
- Mention any managing agent or landlord rules we need to follow
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area

Looking after your system
So the system stays in good health:
- If the breaker trips twice, leave it off
- Never add refrigerant yourself or let anyone top up without finding the leak
- If there’s ice on the pipes, switch off and let it melt
The repair is written up: the cause, the parts fitted and any refrigerant added or recovered. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Filter cleaning is the simplest prevention there is. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips, so keep them clean as the manual describes.
When air con fails in Pegsdon
About 4 listed entries lie within half a mile of central Pegsdon, Bury Farmhouse (grade II) among them. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. About 77% of households live in detached or semi-detached houses, according to Census 2021 figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
The rating label on the unit gives the model number, which helps us bring the right parts.

Common problems we fix in Pegsdon
An error code is the unit’s own diagnosis, in shorthand. Each manufacturer uses its own codes, and the same code can have more than one cause so the code is a starting point, not the answer. Sensors, communication faults between the units and circuit boards are frequent culprits.
If any of these sounds familiar, it’s worth a diagnosis:
- Water leaking from the unit or through the ceiling
- A system that keeps cutting out
- A noisy indoor or outdoor unit
For a school like Hexton Junior Mixed and Infant School, urgent repairs can be booked right away and bigger work in the holidays.
