Air conditioning repair for homes and businesses in Grays

Our emergency line runs 24/7 for urgent breakdowns, such as a server room overheating or water coming through a ceiling. Ring 07833 053749 with the make, what’s happening and any code, and we’ll agree the next steps. If you are dealing with a system that runs but doesn’t cool the room and a system that needs topping up again, we can sort it out.

Shops, offices and homes in Grays all use the same basic kit: an indoor unit, an outdoor unit and the pipes between them. The fault can be at either end, or in between, so testing comes before any new parts.

Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

How the visit works

Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Access to the outdoor unit position is the main thing to tell us about in Grays.

  1. You describe the fault, the make and any error code, ideally with a photo.
  2. At the property, readings and tests narrow the problem down to its cause.
  3. Once the cause is found, we explain it and fix the price for the repair.
  4. We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
  5. The system is run and checked in every mode, and we tell you about anything else we noticed.

Before we arrive

  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Find the manual or the paperwork for the system, if you have it
  • Let us know where the consumer unit is

Your questions about air conditioning repair in Grays

Does sea air affect air conditioning in Grays?

It can. Grays is within about 3 miles of the coast, and salt air speeds up corrosion on outdoor units. We look for corroded coils, fixings and connections on coastal repairs.

Do you cover Grays for air conditioning repair?

Yes, Grays is within the area we cover. Just ring us on 07833 053749, or email if that’s easier with a few details.

Why isn’t my air con cooling?

It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Check the filter and the settings first, and if that doesn’t fix it, phone us on 07833 053749.

Can you repair an R22 air conditioning system?

Most of the time, we recommend replacement. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so we’ll quote for a modern replacement and explain why.

Do you protect the property while you work?

We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.

Can I do the refrigerant work myself?

Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.

What warranty do I get?

The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.

What happens if it’s left?

Faults do not fix themselves. If the system is faulty now, it will be faulty in a heatwave, when you need it most, so it’s worth having it diagnosed while you can plan the repair. Waiting rarely makes an air conditioning problem smaller.

Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.

Before you call an engineer

Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749 or send an email.

Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.

From one of our customers

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
