About our commercial air conditioning in South Harrow
Where equipment generates heat around the clock, the cooling has to keep pace. The design accounts for the equipment’s heat and can include a second unit as backup, so a single fault doesn’t leave the room without cooling. If you are dealing with IT rooms that need resilient cooling and fit-outs and refurbishments that need new air conditioning, we can help.
London buildings in South Harrow can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems can serve many indoor units from a small number of outdoor units, which helps in dense areas.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

How we price commercial air conditioning
A fixed price needs a few facts first. We look at:
- What we find on the survey or diagnosis
- The type of system, from a single split to a larger system
- How many units are involved
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll go through it with you.
Helping us quote
Before you ask for a quote, gather:
- A few photos of the room and the wall the unit is on, or will go on
- Any error code or flashing light on the display
- Where the outdoor unit is, or where you’d like it
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price before any work starts.
South Harrow questions
Is South Harrow in your area for commercial air conditioning?
We do: South Harrow falls inside our working area. To start, call 07833 053749 or write to us at info@aircondoctor.co.uk with a few photos.
Can you fit air conditioning in a London flat in South Harrow?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Do you carry out TM44 inspections?
We are not accredited energy assessors, so we do not inspect. We help before and after, preparing the system and acting on the report.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we will gladly show you ours.
Cooling for South Harrow businesses
Food Standards Agency data counts about 270 restaurants, cafés and canteens, about 4 hotels and guest houses and about 21 schools and colleges within 1.5 miles or so of the middle of South Harrow. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
If you look after a school such as The Welldon Park Academy, classroom, office and IT room cooling is normally installed in the holidays. If you look after a church or hall such as Parish Church of St Paul, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

The process

- We visit the site to look at the building, how it’s used and what the system needs to do.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- Installation is scheduled to fit the business, with out-of-hours and phased work where necessary.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.

- Let us know where the consumer unit is
- Mention any parking restrictions near the property
