About our commercial air conditioning in Grendon Underwood
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, and a fixed-price quote follows. That way the system fits the site and the price is clear before work starts. Typical jobs include changes of use that need a new layout and TM44 recommendations that need acting on, on wall-mounted split systems, ducted systems and VRF systems.
Around Grendon Underwood, there’s usually space for outdoor plant away from the road, out of sight and away from neighbours.
If a fault appears while the equipment is under the manufacturer’s warranty, tell 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.

What the work involves, system by system
Shops and restaurants

FAQs for Grendon Underwood
Do you cover Grendon Underwood for commercial air conditioning?
Yes, Grendon Underwood is within the area we cover. Get in touch with the details and we reply the same working day.
Will you come out to Grendon Underwood?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
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 tell you why.
Is planning permission needed for the outdoor unit?
It can do. The rules differ for heat pumps and cooling-only air conditioning, and for houses, flats, listed buildings and conservation areas. We flag anything that may need permission when we survey, and the council has the final say. This is general information, not legal advice.
Do you have a 24/7 line?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
How long does a commercial installation take?
It takes anything from a day or two for a small office to several weeks of phased work on a large building. The scale and programme decide most of it, and we set out the timing with your quote.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.

For landlords and property managers
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes from a couple of days for a few cassettes to a planned programme for a whole building. We agree a date with you and plan the visit to Grendon Underwood so we arrive with what’s needed.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
How to prepare
- Clear a path to the units and the space around them
- Make sure we can reach the outdoor unit, or where it will go
- Plan for pets to be kept clear during the visit
