Commercial air conditioning for homes and businesses in Middle Assendon
Most businesses need to keep trading while the work is done. We plan out-of-hours, weekend and phased installs, so the building keeps running. The programme is agreed before work begins. We’re often asked to deal with TM44 recommendations that need acting on and buildings that can’t close for the work, across ceiling cassettes, server and comms room cooling and multi-split systems.
For a hall or similar building near Middle Assendon, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What else we do in Middle Assendon
After we’ve gone
Every system needs looking after, and most of it is easy. Our tips:
- Show staff how to use the controls properly
- File every leak check and service record in one place
- Call about warning signs right away
If the system needs F-gas leak checks, we diary the first one and we can cover it under a contract.
Simple control settings help. Units heating and cooling the same space at once is a common problem and correct settings avoid it.
The process
Each visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. On site, the work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. We plan the trip to Middle Assendon around you.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Let us know where the consumer unit is
- Tell us about access, such as roof hatches, high walls or locked plant areas
Get a fixed-price quote
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
