Air conditioning in Great Thorness, done properly
The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote. A lot of the calls we get from Great Thorness are about one room that’s too hot to sleep or work in. That is usually a single wall-mounted split, from £1,200 + VAT.
In a village like Great Thorness, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules don’t apply to it, and the outdoor unit position is chosen to suit the building.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Fixed-price quotes for air conditioning in Great Thorness
Typical ranges are on our prices page, and your quote is built on your job. The quote depends on:
- A single visit or a regular plan
- Which make and model is being fitted or worked on
- The number of rooms, units or zones
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Before you get in touch
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any previous service or F-Gas records
- Where the outdoor unit is, or where you’d like it
- A close-up of the unit’s label showing the model number
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.
Air conditioning around Great Thorness
Great Thorness is within about 1 mile of the coast. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we will tell you if the model you choose has that option. The 2021 Census found about 86% of households in detached or semi-detached houses. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
A loft bedroom or a glazed extension is often the room that prompts the first call. With historic houses such as Swainston Manor about 3 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Great Thorness is about 3 miles south-west of Cowes, in the Isle of Wight. Across the PO31 area, we can help with air conditioning. Great Thorness is one of 125 towns, villages and districts in the Isle of Wight we cover. Worthing, roughly 42 miles off, has its own page on this site.

What else we do in Great Thorness
How it works
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes about a day for a single-room system, longer for multi-room and ducted systems. Work in Great Thorness is booked in advance at a time that suits you.
- First comes a site survey, or photos and measurements for a straightforward job.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Preparing for the visit
- Keep pets out of the rooms we are working in
- Move furniture away from the wall where we will be working
- Tell us about any building rules, permits or sign-in

Before you call an engineer
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring 07833 053749, or email if that’s easier.
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Let filters dry fully before you put them back
- Close windows and doors while the system is cooling
- Leave space around the outdoor unit
Questions after the installation go to the same number. Let us know what’s happening and any error code and we’ll help you sort it out.
Set it and leave it. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.
Great Thorness: your questions answered
Do I need planning permission for air conditioning in Great Thorness?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Great Thorness. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, 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 Great Thorness, usually Isle of Wight council).
Is Great Thorness within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Does air conditioning work as heating?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
