Air conditioning repair for Hatfield

About our air conditioning repair in Hatfield

A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. Common call-outs are for a system that won’t switch on and air conditioning running but not cooling, across ceiling cassettes, wall-mounted split systems and multi-split systems.

Shops, offices and homes in Hatfield 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, which is why we test before we replace parts.

Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

Safe owner checks

Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.

Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.

Aftercare tips

Simple habits make a real difference. We recommend:

  • Keep to the service interval the manufacturer recommends
  • Switch the unit off if water is leaking from it
  • Leave space around the outdoor unit

Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.

Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault and catching it early keeps the repair simpler.

The process

Protection comes first: 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 a single visit for many faults, while some repairs need a second visit once parts arrive, and we tidy up before we leave. A visit in Hatfield is booked for a time that suits you.

  1. First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
  2. Next, a plain explanation and a fixed price.
  3. If the repair is not worth doing, we say so and explain the options.
  4. The treatment: the repair itself, with any leak found and fixed before recharging.
  5. Finally, a check that it’s working and a record of what we did.

Before we arrive

  • Find the manual or the paperwork for the system, if you have it
  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Clear a path to the units and the space around them

Do you offer maintenance contracts?

Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.

How does the warranty work?

It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.

Why isn’t my air con cooling?

There are several possible causes, from simple to serious. Diagnosis confirms the cause, then give you a fixed price to fix it.

What does F-Gas certified mean?

The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
