Your questions about commercial air conditioning in Westmill
Do you cover Westmill for commercial air conditioning?
We do: Westmill falls inside our working area. To start, call us on 07833 053749 or fill in the contact form with a few photos.
Is air conditioning in Westmill permitted development?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 4 buildings and structures within half a mile of the centre of Westmill. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the planning department at North Hertfordshire council, usually the authority for Westmill.
How much does commercial air conditioning cost?
After a site survey, with a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. The rules are set out on GOV.UK and we will help with the system side.
Do you carry out TM44 inspections?
An accredited energy assessor has to carry out the inspection, and we are not assessors. We prepare systems for inspection and carry out the work the report recommends.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.

Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or email us.
Rented and managed buildings
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
We also work for facilities teams in offices, schools and public buildings across Hertfordshire. Larger buildings can be done in stages around the people who use them.
System by system
Ceiling cassettes
A cassette needs space above the ceiling and a route for the condensate. Many include a pump to move the water away, which we check on every service.
Server and comms rooms
Planned maintenance is especially important for continuous cooling and we can cover it under a contract.
