About our commercial air conditioning in High Wych
Heating, cooling and fresh air often go together. Air conditioning systems can heat as well as cool, and we also install ventilation and MVHR, so the building works as a whole. The work covers VRF systems, ceiling cassettes and server and comms room cooling, and the jobs we see most are workspaces that overheat on warm days and older systems on refrigerants that are getting scarcer.
For a business near High Wych, outdoor units typically have room at the back of the building.
Nothing is signed off by word of mouth: 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.

What air conditioning won’t do
A few issues sit outside what this work can do:
- Major builder’s work such as new openings in structural walls
- Carrying out the TM44 inspection itself, which needs an accredited energy assessor
- Formal planning decisions, which rest with the council
Not sure which it is? You can ring us on 07833 053749 and we will tell you honestly before you book.

What owners can safely do
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Managing agents and facilities teams in High Wych
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 can arrange it, prepare the system for it and fix what it finds.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes a few days for a small shop or office, longer for VRF across several floors. A note on how to find the property and where to park makes a visit to High Wych easier.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Dig out any previous service or F-Gas records
- Unlock any gate, garage or side passage we need

Advice
High Wych questions
Do I need planning permission for air conditioning in High Wych?
There’s no single answer: the building and the outdoor unit position decide it. The High Wych Conservation Area is close to the centre of High Wych. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for High Wych, typically East Hertfordshire council) when it matters.
Do you cover smaller places like High Wych?
Yes. High Wych is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
When is a TM44 inspection required?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. The rules are set out on GOV.UK, and we can help you prepare.
Can you come out in an emergency?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will advise on what to do next.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Is there a survey before the work?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
How long will it take to install air conditioning in our building?
As a guide, it takes from a couple of days for a few cassettes to a planned programme for a whole building. Out-of-hours and phased work can spread the programme but keeps the business running.
