Looking after it is simple, and it helps at the next service:
- Keep plant areas tidy
- Avoid units heating and cooling the same space
- Diary TM44 inspections in advance
For systems that require leak checks, the first date goes in the diary and can include it in a maintenance contract.

About our commercial air conditioning in Underriver
Most businesses need to keep trading while the work is done. Work can be done in the evening, at weekends or in phases so disruption is kept down. The timing is set out with your quote. If you are dealing with staff complaining about the temperature and systems that need out-of-hours or phased installation, we can sort it out.
Around Underriver, there’s usually space for outdoor plant away from the road.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Underriver: your questions answered
Can you do commercial air conditioning in Underriver?
Yes. We work across London and the South East from our base in East Grinstead, and Underriver is part of that. To start, phone 07833 053749 or email us with a few photos.
Is Underriver within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
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.
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.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What happens on the day
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes as long as the site and the system need, from a short install to a phased project planned around opening hours. For a village like Underriver, tell us about narrow lanes, gates and parking when you book.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Move furniture away from the wall where we’ll be working
- Unlock any gate, garage or side passage we need
Getting a quote
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, call 07833 053749, or email if that’s easier.

Cooling for Underriver businesses

It just means the planning position is checked before anyone suggests a spot for the outdoor unit.
