Commercial air conditioning in Nether Street
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 one failure does not take everything down. The work covers multi-split systems, server and comms room cooling and VRF systems, and the jobs we see most are new tenancies needing cooling and heating and IT rooms that need resilient cooling.
For a hall or similar building near Nether Street, an air-to-air system that responds quickly suits intermittent use.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Why act early in Nether Street
A system that can’t cope on the hottest days affects everyone in the building. Planning a replacement or upgrade before the summer is easier than reacting in a heatwave. Small faults tend to grow, so it’s worth dealing with them early.

Other services in Nether Street
System by system
Ceiling cassettes
A cassette needs space above the ceiling and a route for the condensate. Many include a pump to move the water away and that’s checked when it’s serviced.
Ducted systems
The unit needs room in the void and an access hatch so filters and drains can be reached.
How the visit works
Each visit runs to the same pattern: check the plan with you, protect the area, do the work, check the system and explain it all to you. On site, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Photos of the existing unit help with repairs and servicing in Nether Street.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the outdoor unit, or where it will go

What commercial work looks like in Nether Street
There are about 3 cafés, restaurants and staff canteens within about 1.5 miles of central Nether Street, according to the Food Standards Agency’s register. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
Healthcare premises near Princess Alexandra Hospital need air conditioning that is easy to clean and maintained on a schedule. If you look after a church or hall such as Parish Church of St John the Baptist, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

Nether Street questions
Can I fit air conditioning in Nether Street without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The Widford Conservation Area takes in the middle of Nether Street. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the planning department at East Hertfordshire council, typically the authority for Nether Street.
Do you cover Nether Street for commercial air conditioning?
We do: Nether Street falls inside our working area. Get in touch with the details and we reply the same working day.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Can I do the refrigerant work myself?
No, not the refrigerant side. 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.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
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.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
