Commercial air conditioning in Windsor
Heating, cooling and fresh air often go together. Air conditioning systems can heat as well as cool, and we also install ventilation and MVHR for a joined-up system. Typical jobs include TM44 recommendations that need acting on and IT rooms that need resilient cooling, on ceiling cassettes, VRF systems and server and comms room cooling.
For a business in Windsor, we fit around opening hours, often over a weekend or a few evenings, and we leave the space clean and working.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. A visit in Windsor is booked for a time that suits you.
- 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.
- We install around your hours, phased where needed.
- The system is commissioned and maintenance can be arranged.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- Unlock any gate, garage or side passage we need
- Keep pets and children away from the work area

Offices
Offices gain heat from occupants, equipment and the sun. The system is sized for what the space really needs with units that fit the layout.
Ceiling cassettes
Only the face of the cassette is visible, which keeps the look of the ceiling tidy.
Owner checks or an engineer?
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Owners can handle the everyday basics: 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.
FAQs for Windsor
Can I get a fixed-price quote for commercial air conditioning in Windsor?
Start with a short message: the address, what you need and a picture or two. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Do you cover Windsor for commercial air conditioning?
We do: Windsor falls inside our working area. Get in touch with the details and we reply the same working day.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
What F-gas duties does a business have?
Operators of systems from 5 tCO2e upwards need leak checks and records. Checks are at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e, and we can handle both.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
When will I hear back?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Commercial air conditioning in Windsor: local notes
There are about 164 cafés, restaurants and staff canteens, about 12 hotels and guest houses and about 52 schools and colleges within about 1.5 miles of central Windsor, according to the Food Standards Agency’s register. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. The centre of Windsor lies within a conservation area. On the National Heritage List, around 7 entries fall within 0.5 miles of the middle of Windsor; St Annes House Convent of St John the Baptist (grade II) is one. None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit.
For a school like St Edward's Catholic First School, air conditioning work is best done out of term. If you look after a church or hall such as All Saints Church, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Note the 5-yearly TM44 date for systems over 12 kW
- Review older R410A systems before they need major repairs
- Report noises, leaks and faults early
For systems that require leak checks, the first date goes in the diary and can include it in a maintenance contract.
Keep records of every service, leak check and repair. For systems at or over 5 tCO2e, they’re required.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
