Commercial air conditioning in Five Oaks

Commercial air conditioning in Five Oaks, done properly

Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside for a joined-up system. Typical jobs include buildings that can’t close for the work and ageing air conditioning that keeps breaking down, on server and comms room cooling, ceiling cassettes and wall-mounted split systems.

Around Five Oaks, there’s usually space for outdoor plant away from the road.

If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

The process

Each visit runs to the same pattern: check the plan with you, protect the area, carry out the job, check the system and explain it all to you. The visit itself takes anything from a day or two for a small office to several weeks of phased work on a large building. Work in Five Oaks is booked in advance at a time that suits you.

  1. It starts with a survey on site, looking at the space, the people in it and the equipment.
  2. A fixed-price quote follows, covering the system type, the layout and the timing.
  3. The work is planned around your opening hours, with out-of-hours or phased work where it helps.
  4. The system goes in, from units and pipework to drainage, wiring and controls.
  5. We commission the system, record the refrigerant details and hand over the controls and documents.

How to prepare

  • Dig out any previous service or F-Gas records
  • Mention any parking restrictions near the property
  • Mention any managing agent or landlord rules we need to follow

Related advice

Why deal with it now?

Where the system is over 12 kW, a TM44 inspection is due at least every 5 years. The recommendations often point to simple improvements and we can do the work they recommend. A dirty or faulty system works harder and costs more to run.

Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll go through it with you.

Looking after your system

Looking after the system is mostly common sense. Our tips:

  • Show staff how to use the controls properly
  • Report noises, leaks and faults early
  • Plan replacements before old systems fail

Once the system is commissioned, we hand over the records, the controls and the manufacturer documents. They’ll be needed for servicing, leak checks and TM44 inspections.

A maintenance contract keeps servicing and F-gas checks on schedule. We agree the visits and the price with your quote.

FAQs for Five Oaks

Is Five Oaks within the area you cover?

Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.

Can you do commercial air conditioning in Five Oaks?

Yes, Five Oaks is within the area we cover. To start, call us on 07833 053749 or use the quote form with a few photos.

Do I get paperwork after the visit?

Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.

Who is responsible for leak checks?

The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

Will I need planning permission?

It can do. Heat pumps and cooling-only units are treated differently, and so are flats, listed buildings and conservation areas. We flag anything that may need permission when we survey, and the council has the final say. This is general information, not legal advice.

Do you carry out TM44 inspections?

We do not carry out the inspection itself, as it needs an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.

Which brands do you work with?

Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.

Before you call an engineer

Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.

What a customer said

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
