For a school like Sandon Junior Mixed and Infant School, air conditioning work is best done out of term. Before any plant goes outside a building like Church of All Saints, its trustees may need planning or heritage advice, and we work with whoever gives it.

About our commercial air conditioning in Sandon
Businesses can’t always stop for an installation. We plan out-of-hours, weekend and phased installs, so the building keeps running. The timing is set out with your quote. The work covers multi-split systems, ducted systems and VRF systems, and people most often call us about staff complaining about the temperature and missing F-gas records for commercial systems.
Around Sandon, commercial jobs tend to be pubs, shops, halls, surgeries and farm or rural businesses. Older buildings may be listed or in a conservation area, so we check the planning side first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Owner checks or an engineer?
There are a few things you can safely do yourself: 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.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
What happens if it’s left?
F-gas leak checks and records are legal duties for most systems at or above 5 tCO2e. Falling behind leaves the operator without the evidence the rules expect and a maintenance contract keeps them on track. A dirty or faulty system works harder and costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Sandon: your questions answered
Will air conditioning in Sandon need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Sandon Conservation Area, close to central Sandon. 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 is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the local planning authority (for Sandon, typically North Hertfordshire council).
Do you cover smaller places like Sandon?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you install in the evenings or at weekends?
We can. Work can be scheduled around your hours and phase it where necessary.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
What are the F-gas responsibilities for commercial air conditioning?
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 carry out the checks and keep the records.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
What we do, step by step
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. The visit takes a few days for a small shop or office, longer for VRF across several floors. A note on how to find the property and where to park makes a visit to Sandon easier.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Let us know if the units are on a roof, a high wall or in a locked area
- Plan for pets to be kept clear during the visit

From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
