Different systems, different jobs
Shops and restaurants
Dining areas fill and empty over the course of service and the controls need to handle that.
VRF and VRV systems
VRF (variable refrigerant flow), also called VRV, connects many indoor units to shared outdoor units. Each zone can be controlled separately, which suits offices, hotels and multi-room buildings.
Commercial air conditioning in Garston
Installation is only the start. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date, at a price fixed with your quote. There’s a 24/7 emergency line for breakdowns. If you are dealing with changes of use that need a new layout and planning ahead for the HFC phase-down, we can sort it out.
Around Garston, many businesses choose systems that heat as well as cool, which can replace old heaters in shops and offices.
Warranty periods vary by brand and by product. 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.

What we’re called out for in Garston
For hospitality, comfort is part of the experience. Each area has its own hours and heat load and that shapes the system and the controls.
Most people get in touch after spotting something like this:
- Comms rooms without enough cooling
- New tenancies needing cooling and heating
- Ageing air conditioning that keeps breaking down
For a school like The Grove Academy, air conditioning work is best done out of term.
Questions to ask before you book
- What paperwork you will receive afterwards
- The make and model of any parts or equipment being quoted
- Whether extra work needs your approval first
Garston questions
Do you cover Garston for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Garston is part of that. Tell us a little about the job and we will take it from there.
Do I need planning permission for air conditioning in Garston?
It depends on the property. The half-mile around the middle of Garston holds about 3 listed buildings and structures. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Garston, usually Watford council).
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
How much does commercial air conditioning cost?
Every commercial job is priced after a site survey. The cost depends on the size of the space, the system and how the work is phased, and you get a fixed-price quote before work starts.
What air conditioning won’t do
To be straight with you, some problems need a different answer:
- Major builder’s work such as new openings in structural walls
- Formal planning decisions, which rest with the council
- Fire risk assessments
If you are not sure, just phone 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you a straight answer.
Parts of the system we cover
- Multi-split systems

The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Send pictures of the space and the outside wall, and we can plan the work near Garston.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- We commission it, hand it over and can set up a maintenance contract.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Let us know where we can park and unload
- Give us access to the outside wall, roof or yard where the outdoor unit sits
