About our commercial air conditioning in Hitchin
Commercial air conditioning comes with F-gas duties for the operator. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We handle the checks and records and remind you when the next is due. The work covers multi-split systems, ducted systems and ceiling cassettes, and people most often call us about new tenancies needing cooling and heating and R410A systems getting dearer to top up.
Restaurant and café kitchens in a town like Hitchin gain heat fast from cooking, which means sizing for the heat and positioning units away from grease.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Let and managed properties
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
We also work for facilities teams in offices, schools and public buildings in Hitchin and across Hertfordshire. Work can be phased by floor, zone or building around the people who use them.
Aftercare tips
Looking after it is simple, and it makes the next visit easier:
- Keep a log for each system
- Tell us early about fit-outs or changes of use
- Review older R410A systems before they need major repairs
Make a note of when a TM44 inspection will be due if the system is over 12 kW. We can prepare the system and act on the report.
Replace ageing systems on your own timetable especially where top-up refrigerant is getting harder to buy.
What commercial work looks like in Hitchin
Food Standards Agency records list about 92 cafés, restaurants and staff canteens, about 4 hotels and guest houses and about 18 schools and colleges within 1.5 miles or so of the middle of Hitchin. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule. Hitchin’s centre falls inside the Hitchin Conservation Area. 4 conservation areas lie within a mile of central Hitchin. Listed buildings are part of the picture here: about 176 within half a mile of the centre, such as Church of Saint Mary (grade I). None of this rules air conditioning out. It just means the planning position is checked before anyone suggests a spot for the outdoor unit.
Churches and halls such as Church of the Holy Saviour are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
Hitchin is about 5 miles north-west of Stevenage, in Hertfordshire. We cover Hitchin for commercial air conditioning, along with the rest of Hertfordshire. In Hertfordshire alone we list 381 places, and Hitchin is one. London is in our area too, about 32 miles from Hitchin.

The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. The work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. For a visit in Hitchin, tell us how to reach the outside wall or the outdoor unit.
- 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 needed.
- The system is commissioned and maintenance can be arranged.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Keep pets out of the rooms we are working in
- Tell us about access, such as roof hatches, high walls or locked plant areas
Ask for a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
Also in Hitchin
Hitchin: your questions answered
Can I get a fixed-price quote for commercial air conditioning in Hitchin?
Send us pictures of the room or the system and a few details about the property. Where pictures aren’t enough, a survey comes first and the fixed-price quote follows.
Is Hitchin in your area for commercial air conditioning?
We do: Hitchin falls inside our working area. Tell us a little about the job and we will take it from there.
Can you work around our opening hours?
Yes. Work can be scheduled around your hours and phase it where necessary.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
When to call us in Hitchin
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine and windows alone cannot always shift it. Air conditioning sized to the actual heat gain keeps the space comfortable.
Most people get in touch after spotting one of these:
- Server rooms running too warm
- Systems over 12 kW due a TM44 inspection
- Ageing air conditioning that keeps breaking down
If you look after a school such as Hitchin Girls' School, classroom, office and IT room cooling is typically installed in the holidays.
What your quote should include
- What’s in the price and what is not
- Proof of F-Gas company certification
- Who does the electrical work, and whether they can certify it
