Questions from St Albans

Is St Albans in your area for air conditioning servicing?

Yes. St Albans is one of the places we cover. Tell us a little about the job and we will take it from there.

Does my air con in St Albans need a yearly service?

For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.

Do you have a 24/7 line?

Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.

Do I get paperwork after the visit?

Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.

Does my air conditioning need an F-gas leak check?

Only if the system is at or above the threshold of 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.

What do you check on an air conditioning service?

The service covers the indoor units and the outdoor unit: the filters, coils, drain and fans, followed by the wiring, controls and refrigerant performance. You get a record of the visit.

Do you work on systems someone else installed?

Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.

About our air conditioning servicing in St Albans

An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We carry out air conditioning servicing for homes and businesses in St Albans and the rest of Hertfordshire, for most leading brands. The work covers ceiling cassettes, VRF systems and air-to-air heat pumps, and common reasons people get in touch are iced-up coils or pipework and systems that haven’t been serviced for a while.

Business systems in St Albans often need F-gas leak checks, with checks at least every 12 months from 5 tonnes CO2 equivalent, and we can combine that with the service.

Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Common problems we fix in St Albans

The outdoor unit lives outside. Leaves, dirt and debris collect on the coil and around the casing, which makes it harder for the unit to shed or pick up heat.

Customers usually contact us after spotting something like this:

  • Frost or ice on the refrigerant pipes
  • Condensate leaking into the room
  • Humming, rattling or squealing from the system

Schools such as Loreto College can book servicing for half term or the summer break, when rooms are empty.

How to choose an air conditioning engineer

How the visit works

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Work at a business in St Albans can be split over a few visits so you keep trading.

  1. First, we agree a time and confirm the cost of the service.
  2. The engineer runs the system and checks how it’s performing.
  3. Then the cleaning: filters, coils, fan and the drain line.
  4. Electrical and refrigerant checks follow, including a leak check if the rules require one.
  5. It’s run once more to confirm all is well, and the record is left with you.

Before we arrive

  • Name a contact who can meet us at the agreed time
  • Let us know if the building has a permit or sign-in process
  • Have the make and model of any existing unit to hand

Honest limits

Not every problem is solved by air conditioning servicing, and we’d rather say so up front. It does not solve:

  • A system short of gas because of a leak
  • Poor original installation, such as drains without a proper fall
  • Rooms that gain heat faster than any unit could cope with

If in doubt, call us on 07833 053749, or email if that’s easier and we’ll say what we think.

System by system

Fans and electrics

We test the controls, the modes and the timers so you know it does what you ask.

Condensate drains and pumps

When the system cools, every indoor unit makes water. The tray is cleaned and the pipe flushed through so the water has a clear path out.
