About our commercial air conditioning in Great Offley
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. We are often asked to deal with planning ahead for the HFC phase-down and offices that get too hot in summer, across ceiling cassettes, wall-mounted split systems and server and comms room cooling.
For a business near Great Offley, outdoor units usually have room at the back of the building.
Each manufacturer sets its own warranty period. For instance, 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.

Common questions in Great Offley
Is planning permission needed for air conditioning in Great Offley?
That depends on the building and where the outdoor unit goes. The centre of Great Offley is in the Great Offley Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the planning department at North Hertfordshire council, usually the authority for Great Offley.
Do you cover smaller places like Great Offley?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Can you install out of hours?
Yes, the programme is built around the site. Every type of building has its own pattern and the plan reflects it.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we will talk you through the next steps.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and AirCon Doctor is certified.
What kind of air conditioning can you install in a business?
Splits, multi-splits, cassettes, ducted units and VRF from leading brands. We set out the choices after surveying the site.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
How the visit works
On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building.

What you can do yourself, and what needs us
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Why act early in Great Offley
In a comms room, losing the cooling can soon become serious. Designing in a backup unit or reviewing the existing set-up is worth doing before anything goes wrong. Planning ahead for a job in Great Offley means we can bring everything needed.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. We give you a fixed price before work begins, so you know where you stand.

For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
