About our commercial air conditioning in Dagnall
Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside, so the building works as a whole. Common call-outs are for server rooms running too warm and planning ahead for the HFC phase-down, on server and comms room cooling, ducted systems and wall-mounted split systems.
Around Dagnall, there’s typically space for outdoor plant away from the road.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

Common questions in Dagnall
Can you do commercial air conditioning in Dagnall?
Yes, Dagnall is within the area we cover. Tell us a little about the job and we will take it from there.
Do you cover smaller places like Dagnall?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Do you offer commercial maintenance contracts?
We do. With a contract, servicing and F-gas checks happen on time and every visit is recorded.
What does the operator have to do under the F-gas rules?
The operator and the service technicians share responsibility. The operator needs to arrange leak checks and keep records where the system requires them and we handle that for you.
Do you provide F-Gas records?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a few days for a small shop or office, longer for VRF across several floors. Pictures of the space and where the outdoor unit could go let us plan the work in Dagnall.
