Different systems, different jobs

F-gas records and TM44
An accredited energy assessor carries out the TM44 inspection. We don’t inspect, but we get systems ready and do the follow-up work.
Commercial air conditioning for homes and businesses in Harlesden
Once a system is in, it needs looking after. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date with the cost agreed up front. Our 24/7 emergency line is there if something goes wrong. If the problem is commercial systems near the end of their life and F-gas leak checks and records that are overdue, we can sort it out.
In a London area like Harlesden, commercial air conditioning goes into offices, shops, restaurants and server rooms, often in shared buildings. So landlord consent, plant positions and noise all need agreeing first, and installs are often done out of hours.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

FAQs for Harlesden
Is Harlesden in your area for commercial air conditioning?
We do: Harlesden falls inside our working area. Just give us a ring on 07833 053749 or send an email with a few details.
Will air conditioning in Harlesden need planning permission?
That depends on the building and where the outdoor unit goes. The centre of Harlesden is in a conservation area. 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 Harlesden, normally Brent council).
Do you offer commercial maintenance contracts?
Yes, and we tailor the schedule to the system and how hard it works. For breakdowns, there’s a 24/7 emergency line.
Do you provide F-Gas records?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
What types of commercial air conditioning do you install?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. We recommend the type that suits your space.
Does servicing affect my warranty?
It depends on 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.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking and we will gladly show you ours.
Commercial air conditioning in Harlesden: local notes
Food Standards Agency data counts about 269 restaurants, cafés and canteens, about 45 schools and colleges and about 45 care, childcare and hospital premises within roughly a mile and a half of the centre of Harlesden. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. About 52% of homes in the Harlesden area were built before 1919, according to Valuation Office Agency council tax records, and about 74% of households live in flats, according to the last census (2021). Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. For London businesses, plant position, noise and access are planned with the building first.

Landlords, agents and facilities managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
After we have gone
So the system stays in good health:
- File every leak check and service record in one place
- Call about warning signs right away
- Do not let servicing slip
For systems that require leak checks, the first date goes in the diary and can include it in a maintenance contract.
Plan replacements before old systems fail especially where top-up refrigerant is getting harder to buy.
How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes as long as the site and the system need, from a short install to a phased project planned around opening hours. In a London area like Harlesden, parking and access are worth sorting out before the day.
- We survey the site and talk through how each area is used.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- The system is installed, wired and connected to its controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
How to prepare
- Dig out any previous service or F-Gas records
- Tell us about any building rules, permits or sign-in
- Unlock any gate, garage or side passage we need
