For landlords and property managers
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.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.
About our commercial air conditioning in Roxbourne
Commercial systems are commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, then send a fixed-price quote. That way the system fits the site and the price is clear before work starts. Common call-outs are for older systems that can’t keep up and R410A systems getting dearer to top up, on VRF systems, server and comms room cooling and ducted systems.
In Roxbourne, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the records and tell you what’s due.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Roxbourne: your questions answered
Will air conditioning in Roxbourne need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Roxbourne sits inside a conservation area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Hillingdon council, usually the authority for Roxbourne when it matters.
Can I have air conditioning in a flat in Roxbourne?
Usually, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
What F-gas duties does a business have?
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 can handle both.
How long does a commercial installation take?
Expect it to take anything from a day or two for a small office to several weeks of phased work on a large building. The size of the building, the system and any phasing make the biggest difference and the programme comes with your quote.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Whose job is it to check the system for leaks?
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 yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What owners can safely do
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Commercial air conditioning around Roxbourne
Food Standards Agency data counts about 184 cafés, restaurants and staff canteens, about 3 hotels and guest houses and about 21 schools and colleges within about 1.5 miles of central Roxbourne. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
For a school like The Moriah Jewish Day School, air conditioning work is best done out of term. For a surgery or clinic in the Clementine Churchill Hospital area, a planned maintenance contract keeps the system clean and its records up to date.

Looking after your system
Every system needs looking after, and most of it is easy. Our tips:
- Keep outdoor units clear of rubbish and stored goods
- Review older R410A systems before they need major repairs
- Agree sensible control settings for each area
If the system needs F-gas leak checks, we diary the first one and can include it in a maintenance contract.
Planned maintenance is the best way to keep a commercial system healthy. We agree the visits and the price with your quote.
