Air conditioning servicing in South Mimms and nearby

Why deal with it now?

A service can find a worn part or a loose connection while the system is still running. Left alone, the same fault tends to show itself when you most need the system. Getting the date in early helps for a place like South Mimms.

No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.

Air conditioning servicing in South Mimms, done properly

For homes with one or two units and businesses with many, we can set up a maintenance contract. We agree the visits, what each one covers and the price with your quote, and the servicing happens on schedule. Common call-outs are for condensate leaking into the room and iced-up coils or pipework, on ducted systems, air-to-air heat pumps and multi-split systems.

Several units at a home near South Mimms can be serviced in one visit.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Servicing in South Mimms: local notes

Tell us where your outdoor unit is and how to reach it, so we can plan the visit. Central South Mimms is inside the South Mimms Conservation Area. There are 2 conservation areas within a mile of the centre of South Mimms. On the National Heritage List, around 13 entries fall within 0.5 miles of the middle of South Mimms; Church of St Giles (grade I) is one.

Questions from South Mimms

Do you cover South Mimms for air conditioning servicing?

We do: South Mimms falls inside our working area. Tell us a little about the job and we’ll take it from there.

How often do you service systems in South Mimms?

For most homes, once a year. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.

Do you offer air conditioning maintenance contracts?

Yes, and the schedule is set around your system. We agree the cost up front and you get a record after each visit.

Will servicing keep my manufacturer’s warranty valid?

Warranty terms are set by the manufacturer, not by us. Read the conditions for your brand, as they may include servicing and file every service record.

Can you set up regular servicing?

Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.

Who is responsible for leak checks?

The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.

What accreditations do you have?

AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.

Rented and managed buildings

If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.

Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.

When to call us in South Mimms

Vibration and temperature changes can loosen electrical connections over time. That can lead to intermittent faults which is why they’re checked on every service.

Common reasons people call us are:

  • Smells coming from the indoor unit
  • Leak check records that need bringing up to date
  • A unit showing a fault code

Site managers at schools like St Giles' CofE Primary School can have the site’s units serviced during a holiday.

What your quote should include

  • Whether a new circuit is included and who certifies it
  • Whose warranty applies, and on what terms
  • If the quote is based on a survey, pictures or a diagnosis

How to choose an air conditioning engineer

What happens on the day

Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. On site, it takes anything from an hour for a simple split system to most of a day for a larger installation. We plan the trip to South Mimms around you.

  1. When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
  2. The engineer switches the system on and checks how it behaves before taking anything apart.
  3. Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
  4. Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
  5. You get a service record, with anything that needs attention explained.

Before we arrive

  • Make sure someone can let us in at the agreed time
  • Tell us about any building rules, permits or sign-in
  • Clear the space around the indoor unit, or where it will go

Getting a price

Here’s what helps us quote: where the property is and what kind of building it is, photos of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, phone 07833 053749 or send an email.
