Our coverage in St Albans
St Albans supports a mix of high-street retail, professional offices, hospitality and light industry. Watford is about 11 km away.
That includes premises in AL1 and AL3 and the surrounding districts. We also work in nearby Harpenden, Hatfield and Hemel Hempstead.
Buildings across Hertfordshire range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
Before a visit in St Albans we ask for the make, model and number of units so the engineer arrives with the right filters, parts and access equipment.

Things to check in St Albans
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Working hours
Most St Albans businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Leased premises
If your St Albans premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
FAQs for St Albans
How much does commercial air conditioning cost in St Albans?
A single wall-mounted split typically costs £1,550–£2,650 plus VAT installed in St Albans, and a ceiling cassette £2,295–£5,350 per unit. A small shop or office with two to four indoor units usually comes to £5,350–£17,795 plus VAT.
Do you also cover Harpenden, Hatfield and Hemel Hempstead?
Yes. Alongside St Albans, we also cover Harpenden, Hatfield and Hemel Hempstead. Each has its own page with local guide prices.
Is the survey free?
Yes, for new installations and replacements on the UK mainland. Service, repair and inspection visits are priced before we book them.
Which refrigerant do new systems use?
Most new small split systems use R32, because new single splits under 3 kg in Great Britain cannot use refrigerants with a GWP of 750 or more. Larger systems vary by equipment.
Can you work outside our opening hours?
Yes. Early starts, evenings and weekends can be arranged, and any extra cost is shown in the quote.
