What we do, step by step
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes as long as the fault needs, from a quick fix to a return visit for parts. A few pictures of the room, the outside wall and the fuse board help us plan a job in Stevenage.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
Preparing for the visit

- Let us know where the consumer unit is
- Clear a path to the units and the space around them

How we handle air conditioning repair in Stevenage
We treat a faulty system the way a doctor treats a patient: find the cause, put it right and check it’s healthy before we leave. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. The work covers heat pumps, VRF systems and wall-mounted split systems, and the jobs we see most are a fault code on the display and new noises from the system.
For a shop or office in Stevenage, a system that stops in a heatwave is a real problem. The emergency line is open 24/7, with repair call-outs from £75 + VAT.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Different systems, different jobs
Fans and compressors
The compressor is the heart of the system. Before blaming the compressor, we check the electrics and the refrigerant circuit. If it has failed, we compare the cost of repair with replacement.
Ducted and cassette systems
Water through a ceiling below a cassette or ducted unit needs prompt attention. The cause is normally the condensate pump, a blocked drain or a tray that’s overflowing, and we check all three.
What air conditioning repair cannot fix
Air conditioning repair can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
- Heat gains the system was never designed for
- No power to the building at all
If you’re not sure, just call 07833 053749 and we’ll give you a straight answer before you book.
Parts of the system we cover
- VRF systems
- Ceiling cassettes
- Wall-mounted split systems
- Multi-split systems
- Heat pumps
- Ducted systems

Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
