About our commercial air conditioning in Dorchester
Many sites need more than cooling. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside, so the building works as a whole. The work covers wall-mounted split systems, VRF systems and multi-split systems, and common reasons people get in touch are installs that must fit around trading hours and server rooms running too warm.
If you run a village hall or similar building near Dorchester, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

After we’ve gone
To keep the system working properly:
- Call about warning signs straight away
- File every leak check and service record in one place
- Agree sensible control settings for each area
After commissioning, you get the F-gas records, handover notes and the manufacturer’s paperwork. Keep them together for future servicing and inspections.
Train staff to use the controls sensibly. Systems fighting each other, or set to extremes, waste effort and correct settings avoid it.
Dorchester questions
Can I fit air conditioning in Dorchester without planning permission?
The answer turns on the property and where the outdoor unit would sit. The Dorchester Conservation Area takes in the middle of Dorchester. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at South Oxfordshire council, typically the authority for Dorchester.
Do you cover Dorchester for commercial air conditioning?
Yes. Dorchester is one of the places we cover. Get in touch with the details and we reply the same working day.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Do you have a 24/7 line?
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’ll tell you what to do first.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s 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.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Can you do our TM44 air conditioning inspection?
We are not accredited energy assessors, so we do not inspect. We help before and after, preparing the system and acting on the report.
What affects the cost of commercial air conditioning
The quote reflects the job in front of us. We consider:
- The equipment or parts the job needs
- Whether it’s a one-off job or part of a maintenance contract
- What state the existing equipment is in
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed price.
Asking for a quote
Before you ask for a quote, gather:
- A short video of any fault, such as a noise or a flashing light
- The postcode and whether it’s a home, flat or business
- Your consumer unit or fuse board
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Signs you need commercial air conditioning in Dorchester
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine, and opening windows doesn’t always help. A system sized for the real heat load deals with it.
What we’re most often called about:
- Systems that need out-of-hours or phased installation
- Comms rooms without enough cooling
- Workspaces that overheat on warm days
Schools such as Dorchester St Birinus Church of England School typically have the work done in the holidays, when classrooms are empty.
What your quote should include
- If the quote is based on a survey, pictures or a diagnosis
- What happens if the job turns out to be different on the day
- Whether the electrical work is done by a registered contractor, such as NICEIC approved

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. On the day, both are in the same hands. On site, it takes from a couple of days for a few cassettes to a planned programme for a whole building. Seeing the property in photos first means the trip to Dorchester can be planned properly.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
Before we arrive
- Arrange for someone to be there to let us in
- Keep pets out of the rooms we are working in
- Find the manual or the paperwork for the system, if you have it
