Fixed-price quotes for commercial air conditioning in Trowley Bottom
We quote each job individually. These are the things that affect it:
- The number of rooms, units or zones
- How far the pipework has to run, and where
- What electrical work the job needs
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, phone us on 07833 053749, or email if that’s easier for straight advice and a fixed price.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- A close-up of the unit’s label showing the model number
- The address and the type of property
- Wide photos of the room or the existing unit
For a fixed-price quote, phone us on 07833 053749 or send an email with the address and a few details about the rooms or units involved. Photos help a lot. We reply to enquiries the same working day.
About our commercial air conditioning in Trowley Bottom
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we’re not assessors, but we prepare systems for inspection and act on what the report finds. We’re often asked to deal with fit-outs and refurbishments that need new air conditioning and leak check schedules that have slipped, on ceiling cassettes, multi-split systems and ducted systems.
In a village like Trowley Bottom, commercial air conditioning is normally for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed, so planning comes first.
Whatever the visit, you get a written record: 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, because it helps with any later warranty question.

For landlords and property managers

Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Questions from Trowley Bottom
Is Trowley Bottom within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you do commercial air conditioning in Trowley Bottom?
Yes, Trowley Bottom is within the area we cover. Just call us on 07833 053749 or email us with a few details.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will skipping a service affect the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
How long will it take to install air conditioning in our building?
It takes anything from a day or two for a small office to several weeks of phased work on a large building. The size of the building, the system and any phasing make the biggest difference and the programme comes with your quote.
Does my building need a TM44 inspection?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Which commercial systems do you fit?
We install wall-mounted, cassette, ducted, multi-split and VRF systems. The right one depends on the building and how it’s used.
What happens on the day
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first.

Related advice
After we have gone
A little care keeps the system in better shape. Our advice:
- Show staff how to use the controls properly
- Call about warning signs right away
- Leave space around outdoor units
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. We can prepare the system and act on the report.
Good records make inspections and audits easier. They’re part of the operator’s F-gas duties for systems that need checks.
