After we’ve gone
After the visit, a few habits help:
- Budget for replacing ageing plant
- Agree sensible control settings for each area
- Call about warning signs right away
For systems that require leak checks, the first date goes in the diary and we can cover it under a contract.
Keep filters clean and plant areas clear. Blocked filters and obstructed outdoor units make the system work harder.
How we handle commercial air conditioning in Northolt
Every commercial job is commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, and a fixed-price quote follows. So you know exactly what you are getting and what it costs. If you’re dealing with installs that must fit around trading hours and server rooms running too warm, we can help.
Commercial systems in Northolt are often in shared buildings: offices above shops, restaurants below flats. So landlord consent, plant positions and noise all need agreeing first, and the work is typically planned around trading hours.
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.

What happens on the day
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we tidy up before we leave. Let us know who controls access to the building in Northolt, as that saves time on the day.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Let us know where the consumer unit is

Getting a price
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, call 07833 053749 or fill in the contact form.

Northolt questions
Is Northolt in your area for commercial air conditioning?
We do: Northolt falls inside our working area. Just ring 07833 053749 or email us with a few details.
Do I need permission to put air conditioning in my flat in Northolt?
Often, yes, but the lease and the freeholder typically have a say. 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.
Do you offer commercial maintenance contracts?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. The visits and price are fixed with your quote.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Do you carry out TM44 inspections?
We are not accredited energy assessors, so we do not inspect. We can prepare for the inspection and put right what it finds.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
How we price commercial air conditioning
The price is fixed before any work begins. It’s based on:
- Access, including height, roofs and ladders
- Whether it’s a simple split or a larger system
- What electrical work the job needs
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, ring us on 07833 053749 or send an email, and we’ll explain what it covers.
Before you get in touch
To speed up the quote, please include:
- The fuse board and where it is in the property
- Where the property is and what kind of building it is
- The remote or wall controller showing any error
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
Different systems, different jobs
Ducted systems
A single ducted unit can feed several grilles, depending on the layout.
Offices
Offices gain heat from occupants, equipment and the sun. The system is sized for what the space really needs and choose units that suit the ceiling and layout.
