Your questions about commercial air conditioning in Portfield
Do you cover Portfield for commercial air conditioning?
We do: Portfield falls inside our working area. Tell us a little about the job and we will take it from there.
Can I fit air conditioning in Portfield without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 53 buildings and structures within half a mile of the centre of Portfield. 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 Portfield, normally Chichester council).
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: a look first, a fixed-price quote and written records.
Can you work around our opening hours?
We can. We fit the installation around when the building is in use, including phased work floor by floor.
Can you do our TM44 air conditioning inspection?
We do not carry out the inspection itself, as it needs an accredited energy assessor. Our part is getting the system ready and doing the follow-up work.
Commercial air conditioning in Portfield, done properly
The right system depends on the building. Wall-mounted splits suit small offices and single rooms, cassettes suit open ceilings, ducted units hide away in ceiling voids, and VRF or VRV serves many rooms from shared outdoor units. We explain the options and why we’d choose one over another. If you are dealing with buildings that can’t close for the work and planning ahead for the HFC phase-down, we can help.
In a place like Portfield, commercial air conditioning is often for a shop, a surgery, a pub, an office unit or a farm business. Many need just one to four indoor units, sized from a site survey.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What the work involves, system by system
Shops and restaurants
In retail and hospitality, comfort is part of the business. We plan installs outside trading hours where possible to keep trading.
VRF and VRV systems
Larger systems carry more refrigerant so leak checks and records often apply. We work out the tCO2e and set the check schedule.
When to call us in Portfield
Older systems running on R410A face rising costs for top-ups as the GB HFC phase-down tightens supply. Repairs on existing R410A systems remain legal though it’s worth bearing in mind when planning ahead.
If any of these sounds familiar, it’s worth a diagnosis:
- TM44 recommendations that need acting on
- R410A systems getting dearer to top up
- Systems that need out-of-hours or phased installation
Churches and halls such as St George's 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.
Questions to ask before you book
- Exactly what the price includes, from supply and fitting to commissioning
- Whether a new circuit is included and who certifies it
- Proof of F-Gas company certification
