Commercial air conditioning in Hertford
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we’re not assessors, but we prepare systems for inspection and act on what the report finds. The work covers ceiling cassettes, ducted systems and VRF systems, and people most often call us about buildings that can’t close for the work and comms rooms without enough cooling.
Kitchens and dining rooms in Hertford heat up quickly, so they need units sized for the load and placed away from grease and steam.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Common questions in Hertford
Is Hertford in your area for commercial air conditioning?
We do: Hertford falls inside our working area. Get in touch with the details and we reply the same working day.
How do I get a quote for commercial air conditioning in Hertford?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Can you install out of hours?
Yes, we plan out-of-hours, weekend and phased installs to keep disruption down. We set out the timing before work starts.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
How long does the visit take?
We will confirm the time with your quote. As a guide, the work takes as long as the site and the system need, from a short install to a phased project planned around opening hours.
Why deal with it now?
TM44 inspections are required at least every 5 years for systems over 12 kW. Acting on the findings can improve how the system runs, and we can carry out the work. In a town like Hertford, the first hot week of the year is when most people call, so booking early helps.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

Before you call an engineer
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Business air conditioning in Hertford
Food Standards Agency records list about 62 cafés, restaurants and staff canteens, about 3 hotels and guest houses and about 22 schools and colleges within 1.5 miles or so of the middle of Hertford. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. Central Hertford is inside the Hertford Conservation Area. About 261 listed entries lie within half a mile of central Hertford, Shire Hall (grade I) among them. Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the local planning authority (typically East Hertfordshire council) has the final say on what’s allowed.
For premises near Hertford East station, we plan plant positions and working hours with the landlord or managing agent first, where there is one. For a surgery or clinic in the Hertford County Hospital area, a planned maintenance contract keeps the system clean and its records up to date.

The process
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, carry out the job, check the system and talk you through it. The visit itself takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Access to the outdoor unit position is the main thing to tell us about in Hertford.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- 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.
Before we arrive
- Mention any roof access, ladders or high-level work
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Arrange for someone to be there to let us in
Getting a quote
Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, phone 07833 053749 or email us.
