Commercial air conditioning for homes and businesses in Harpenden
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, then send a fixed-price quote.

Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads.

Keeping the system healthy
So the system stays in good health:
- Review older R410A systems before they need major repairs
- Plan the air conditioning alongside the fit-out
- Agree sensible control settings for each area
Make a note of when a TM44 inspection will be due if the system is over 12 kW. We can prepare the system and act on the report.
Replace ageing systems on your own timetable, particularly where they use R410A.
Harpenden questions
What’s the best way to get a price for commercial air conditioning in Harpenden?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Do I need planning permission for air conditioning in Harpenden?
It depends on the property. The centre of Harpenden is in the Harpenden Conservation Area. 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 local planning authority (for Harpenden, typically St Albans City council).
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Who has to arrange F-Gas 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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you carry out TM44 inspections?
An accredited energy assessor has to carry out the inspection, and we’re not assessors. We prepare systems for inspection and carry out the work the report recommends.
When is a TM44 inspection required?
Where the air conditioning is over 12 kW, an inspection is needed at least every 5 years. An accredited energy assessor carries it out, and we can prepare the system and act on the report.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
