Commercial air conditioning for homes and businesses in Chiswell Green
The right system depends on the building. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We explain the options and why we’d choose one over another. If the problem is work raised by a TM44 inspection and new tenancies needing cooling and heating, we can sort it out.
Around Chiswell Green, commercial jobs are usually a shop, surgery, pub, office or workshop. Many need just one to four indoor units, and we size them from a survey.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Common questions in Chiswell Green
Is planning permission needed for air conditioning in Chiswell Green?
It depends on the property. The half-mile around the middle of Chiswell Green holds about 5 listed buildings and structures. 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 isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Chiswell Green, typically St Albans City council).
Is Chiswell Green in your area for commercial air conditioning?
We do: Chiswell Green falls inside our working area. Tell us a little about the job and we will take it from there.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Do you offer commercial maintenance contracts?
Yes, and we tailor the schedule to the system and how hard it works. There’s also a 24/7 emergency line for breakdowns.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Can you do our TM44 air conditioning inspection?
The inspection itself must be done by an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Leave it or put it right?
R410A systems are still legal to repair, though supply of the gas is tightening. Planning a replacement on your own timetable beats replacing it after a major failure. An early booking makes the visit to Chiswell Green easier to arrange.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.
