Commercial air conditioning for homes and businesses in North Harrow
Commercial air conditioning is a big part of what we do, for businesses in North Harrow and the rest of Greater London. Offices, shops, restaurants, hotels, schools and server rooms all come with different demands, and each one gets a system chosen for how the space is used. The work covers VRF systems, ceiling cassettes and multi-split systems, and people most often call us about leak check schedules that have slipped and commercial systems near the end of their life.
Commercial systems in North Harrow are often in shared buildings: offices above shops, restaurants below flats. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and installs are often done out of hours.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What affects the cost of commercial air conditioning
Typical ranges are on our prices page, and your quote is built on your job. The quote depends on:
- Whether it’s a simple split or a larger system
- A single visit or a regular plan
- The brand, model and parts involved
What you pay reflects the actual work. That’s why every job is looked at first, and why the quote is fixed before we start.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- The postcode and whether it’s a home, flat or business
- A photo of the consumer unit with the cover closed
- The outside wall, roof or yard where the outdoor unit sits or would go
Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes from a couple of days for a few cassettes to a planned programme for a whole building. For a job in North Harrow, tell us about parking, permits and access to the building when you get in touch.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Getting ready for the visit
- Let us know where the consumer unit is
- Arrange for someone to be there to let us in
- Mention any roof access, ladders or high-level work
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. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To get going, call 07833 053749 or email us.

Keeping the system healthy
How well a system lasts depends on use and care. Here’s what we suggest:
- Budget for replacing ageing plant
- File every leak check and service record in one place
- Note the 5-yearly TM44 date for systems over 12 kW
Equipment warranties come from the manufacturer. We go through the manufacturer’s conditions with you and you’ll know what they ask for.
Simple control settings help. Units heating and cooling the same space at once is a common problem and correct settings avoid it.
Business air conditioning in North Harrow
Food Standards Agency data counts about 272 cafés, restaurants and staff canteens, about 4 hotels, B&Bs and guest houses and about 15 schools and colleges within 1.5 miles or so of the middle of North Harrow. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. For London businesses, plant position, noise and access are planned with the building first.
A bursar or site manager at a school like Longfield Primary School will want the install planned around the school calendar, and we work to that. Before any plant goes outside a building like Church of St Alban, its trustees may need planning or heritage advice, and we work with whoever gives it.

North Harrow: your questions answered
Can I have air conditioning in a flat in North Harrow?
Normally, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is air conditioning in North Harrow permitted development?
The answer turns on the property and where the outdoor unit would sit. The centre of North Harrow is in a 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 needed, we check with the planning department at Harrow council, normally the authority for North Harrow.
Is there a survey before the work?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Can you do our TM44 air conditioning inspection?
The inspection itself must be done by an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Managing agents and facilities teams in North Harrow
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 are happy to deal with either side and send the records to whoever needs them.
Keeping records across a portfolio is half the battle. Every visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
