How we handle air conditioning servicing in Highfield

People in Highfield book a service for all sorts of reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. Whatever the reason, the visit follows the same thorough checks. The work covers air-to-air heat pumps, wall-mounted split systems and ceiling cassettes, and the jobs we see most are new noises from the indoor or outdoor unit and ice forming on the pipework or outdoor unit.

Outdoor units around Highfield tend to be close to gardens and hedges, so the outdoor coil can clog with leaves and seeds. Every service includes cleaning it.

AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Let and managed properties

Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.

We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.

When to call us in Highfield

Dust settles on the filters every time the unit is on. Clogged filters choke the airflow and the unit has to work harder to reach the set temperature.

Customers normally contact us when they notice something like this:

  • Frost or ice on the refrigerant pipes
  • Smells coming from the indoor unit
  • New noises from the indoor or outdoor unit

Booking before the first hot spell means the system is ready when you need it.

What to look for in a quote

  • Whether they hold F-Gas company certification, not just individual qualifications
  • Whose warranty applies, and on what terms
  • Whether anyone has checked the property or the system first

How to choose an air conditioning engineer

The process

Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Seeing the property in pictures first helps us plan the trip to Highfield.

  1. We start with the details of the system and anything you’ve noticed.
  2. Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
  3. The outdoor unit is cleaned and checked, and debris cleared from around it.
  4. We test the electrics, the controls and how the refrigerant circuit is performing.
  5. If a repair is needed, you hear why and what it costs before anything is done.

Before we arrive

  • Mention any parking restrictions near the property
  • Dig out any previous service or F-Gas records
  • Keep pets and children away from the work area

Getting a quote

The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Highfield: your questions answered

Will you come out to Highfield?

Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.

How often should air conditioning in Highfield be serviced?

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

Can we book visits on a schedule?

Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.

When will I hear back?

On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.

Which brands do you work with?

The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.

Can you come out in an emergency?

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

Will I get records for the system?

Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

What a service looks like in Highfield

On the National Heritage List, around 3 entries fall within 0.5 miles of the middle of Highfield; Little Farmhouse (grade II) is one. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. About 51% of homes in and around Highfield date from 1945 to 1972, according to VOA council tax data, and about 40% of households live in terraced houses, according to the 2021 Census. On terraced streets, outdoor units are normally at the back, so tell us how we get to the rear of the property.

Site managers at schools like Yewtree Primary School can have the site’s units serviced during a holiday.
