Commercial air conditioning in Longford
We design, install and look after air conditioning for businesses in Longford and across Slough. That includes offices, shops, restaurants, hotels, schools and server rooms and we choose the system to suit the space and the way it’s used. If the problem is ageing air conditioning that keeps breaking down and workspaces that overheat on warm days, we can sort it out.
For a hall or similar building near Longford, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Questions from Longford
Is Longford within the area you cover?
Yes. Longford is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is planning permission needed for air conditioning in Longford?
The answer turns on the property and where the outdoor unit would sit. Central Longford is a short walk from the Longford Village 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 Hillingdon council, normally the authority for Longford.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Longford and across Slough. Let us know who the records should go to.
Can you work around our opening hours?
Yes, timing is agreed to suit you. Shops, offices, restaurants and schools all have different needs and the plan reflects it.
Can you do our TM44 air conditioning inspection?
No, the inspection needs an accredited energy assessor. We can prepare for the inspection and put right what it finds.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you offer commercial maintenance contracts?
Yes, with visits planned around the site. There’s also a 24/7 emergency line for breakdowns.
What air conditioning won’t do
A few issues sit outside what this work can do:
- Issuing TM44 reports
- Plumbing beyond the condensate drainage
- Formal planning decisions, which rest with the council
Not sure which it is? You can phone 07833 053749 or email us and we will tell you honestly.
What the work covers

Before you call an engineer
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
What we’re called out for in Longford
A TM44 report, an F-gas audit or an insurer’s question can prompt the call. We carry out the work and make sure the paperwork is in order and you have the evidence to hand.
Look out for any of the following:
- R410A systems getting dearer to top up
- Commercial systems near the end of their life
- Workspaces that overheat on warm days
A bursar or site manager at a school like Pippins School will want the install planned around the school calendar, and we work to that.
Questions to ask before booking
- The make and model of any parts or equipment being quoted
- How VAT is shown, and which rate applies
- Whether the manufacturer’s warranty depends on regular servicing
The process
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. Photos of the existing unit help with repairs and servicing in Longford.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Mention any roof access, ladders or high-level work
- Clear access to the fuse board
