Owner checks or an engineer?
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
About our commercial air conditioning in Whempstead
Most businesses need to keep trading while the work is done. We plan out-of-hours, weekend and phased installs so disruption is kept down. The timing is set out with your quote. If you are dealing with comms rooms without enough cooling and workspaces that overheat on warm days, we can help.
If you run a village hall or similar building near Whempstead, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Whempstead: your questions answered
Can I fit air conditioning in Whempstead without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 5 buildings and structures within half a mile of the centre of Whempstead. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with East Hertfordshire council, which is usually the planning authority for Whempstead.
Do you cover smaller places like Whempstead?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. At the end, we clear up and show you what we have done.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
What does the operator have to do under the F-gas rules?
For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. The intervals are at least yearly from 5 to under 50 tCO2e, and 6-monthly from 50 to under 500 tCO2e, and we can handle both.
Does my building need a TM44 inspection?
Over 12 kW, a TM44 inspection is needed at least every 5 years. GOV.UK has guidance on how it works, and we can help you prepare.
Can you work around our opening hours?
We do: evening, weekend and phased installation are all possible to keep disruption down. We set out the timing before work starts.
How it works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any 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. If a lane or gateway near Whempstead is tight for a van, let us know and we’ll plan for it.
- We survey the site and talk through how each area is used.
- 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.
- We commission the system and hand over the F-gas records and controls.
Getting ready for the visit
- Let us know where we can park and unload
- Plan for pets to be kept clear during the visit
- Let us know if the building has a permit or sign-in process
Getting a price
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price before any work starts.
Advice
What the work involves, system by system
Server and comms rooms
A backup unit can keep the room cool if one fails and we can explain how they would work together.
VRF and VRV systems
VRF (variable refrigerant flow), also called VRV, connects many indoor units to shared outdoor units. Each zone can be controlled separately making it a common choice for larger buildings.
Why act early in Whempstead
In a comms room, losing the cooling can soon become serious. Reviewing the cooling and adding resilience is best done in advance. Dealing with it now is typically simpler than a breakdown later.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and the parts and time the job needs. You get a fixed price before we start, so there are no surprises.

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.”
