Commercial air conditioning for homes and businesses in Hammerwood
Server rooms and comms rooms need cooling that keeps going. We look at the heat load and how the room is used, and can discuss backup units, so a single fault doesn’t leave the room without cooling. Common call-outs are for buildings that can’t close for the work and older systems that can’t keep up, on ceiling cassettes, ducted systems and VRF systems.
For a business near Hammerwood, outdoor units usually have room at the back of the building, out of sight and away from neighbours.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

FAQs for Hammerwood
Can you do commercial air conditioning in Hammerwood?
We do: Hammerwood falls inside our working area. To start, give us a ring on 07833 053749 or send an email with a few photos.
Do I need planning permission for air conditioning in Hammerwood?
It depends on the property. Historic England lists about 6 buildings and structures within half a mile of the centre of Hammerwood. 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 Mid Sussex council, which is usually the planning authority for Hammerwood.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
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.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
How often is a TM44 inspection needed?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. GOV.UK has guidance on how it works, and we can help you prepare.
What happens on the day
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 a follow-up is pointed out there and then. All told, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Work in Hammerwood is booked in advance at a time that suits you.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- We install around your hours, phased where needed.

Getting a price
Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then call us on 07833 053749 or drop us a line.
Advice
Safe owner checks
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call 07833 053749 or email us.
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.
