What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Seeing the property in photos first helps us plan the trip to St Stephens.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Plan for pets to be kept clear during the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas

Related advice
Commercial air conditioning in St Stephens
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we’re not assessors, but we prepare systems for inspection and act on what the report finds. Common call-outs are for commercial systems near the end of their life and server rooms running too warm, on multi-split systems, VRF systems and wall-mounted split systems.
In a place like St Stephens, commercial air conditioning is often for a shop, a surgery, a pub, an office unit or a farm business. Most need one to four indoor units, sized from a site survey.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Before you call an engineer
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Before you call us about a fault, a few checks can save a visit: 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 call 07833 053749.
What commercial air conditioning cannot fix
Some problems need a different service or another trade:
- Getting landlord or building owner approval
- Building work beyond the installation itself
- Acting as the energy assessor
If you are not sure, just phone 07833 053749 or fill in the contact form and we will give you a straight answer.

Questions from St Stephens
Is air conditioning in St Stephens permitted development?
It depends on the property. Central St Stephens sits inside the St Albans Conservation Area. 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 necessary, we check with St Albans City council, which is normally the planning authority for St Stephens.
Do you cover smaller places like St Stephens?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Do you provide F-Gas records?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
How are commercial air conditioning installs priced?
A survey comes first, then a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
