Commercial air conditioning for homes and businesses in Long Sutton
Commercial air conditioning is a big part of what we do, for businesses in Long Sutton and the rest of Hampshire. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands, and each one gets a system chosen for how the space is used. If the problem is older systems on refrigerants that are getting scarcer and installs that must fit around trading hours, we can sort it out.
Around Long Sutton, there’s typically space for outdoor plant away from the road, out of sight and away from neighbours.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.

What happens on the day
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we tidy up before we leave. Work in Long Sutton is booked in advance at a time that suits you.

Long Sutton questions
Do you cover smaller places like Long Sutton?
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.
Will air conditioning in Long Sutton need planning permission?
That depends on the building and where the outdoor unit goes. Central Long Sutton sits inside a 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 is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with Hart council, which is normally the planning authority for Long Sutton.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Do you provide ongoing maintenance for businesses?
We do. A contract keeps the system serviced and any required leak checks on schedule, with records kept for each visit.
How long will it take to install air conditioning in our building?
As a guide, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Phased or out-of-hours work may extend it though it keeps disruption down.
Do you look at the job first?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
How often is a TM44 inspection needed?
Over 12 kW, a TM44 inspection is needed at least every 5 years. The rules are set out on GOV.UK and we will help with the system side.

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.”
