About our commercial air conditioning in Allen's Green
Many sites need more than cooling. Air conditioning systems can heat as well as cool, and we also install ventilation and MVHR, so the building works as a whole. Typical jobs include buildings that can’t close for the work and commercial systems near the end of their life, across VRF systems, multi-split systems and wall-mounted split systems.
For a hall or similar building near Allen's Green, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

How it works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes anything from a day or two for a small office to several weeks of phased work on a large building. We agree a date with you and plan the visit to Allen's Green so we arrive with what’s needed.
- 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.
- 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.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Let us know where we can park and unload
- Find the manual or the paperwork for the system, if you have it
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Common questions in Allen's Green
Can I fit air conditioning in Allen's Green without planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 12 listed entries sit within 0.5 miles of central Allen's Green. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Allen's Green, normally East Hertfordshire council).
Will you come out to Allen's Green?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Allen's Green and across Hertfordshire. Let us know who the records should go to.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Do you need commercial air conditioning in Allen's Green?
A fit-out, refurbishment or change of use often means rethinking the air conditioning. New partitions, more staff or different equipment change the heat load and the system needs to match the new layout.
Reasons to give us a call include:
- Offices that get too hot in summer
- Systems that need out-of-hours or phased installation
- TM44 recommendations that need acting on
If you run a surgery, clinic or pharmacy in the area around Herts and Essex Hospital, about 3.4 miles north-east, cleanable, quiet units and regular maintenance matter.

Let and managed properties
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
