Air con installers in Michelmersh
Air conditioning installation, in Michelmersh and nearby. Call for a fixed-price quote, and we will reply the same working day.
- Not knowing which system, size or brand to choose
- Expensive direct electric heating
- An office, shop or restaurant that is uncomfortable for staff and customers
What happens on the day
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes a day or more, depending on the number of rooms, the pipe routes and the access. We plan the trip to Michelmersh around you.
- First comes a site survey, or pictures and measurements for a straightforward job.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board
- Keep pets and children away from the work area

Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Space outside is rarely the problem in a place like Michelmersh. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and call 07833 053749 or email us.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Leave it or put it right?
New systems now use lower-impact refrigerants. Since 2025, new single split systems with less than 3 kg of refrigerant can’t use F gases with a GWP above 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Small faults tend to grow, so it’s worth dealing with them early.
The price reflects the work, not guesswork. That is why we look at the job first, from pictures or on a survey, and the price is agreed before any work starts.

What an install looks like in Michelmersh
About 45% of homes in Michelmersh and the neighbourhoods around it have been built since 2000, according to Valuation Office Agency council tax records, and the 2021 Census found about 73% of households in detached or semi-detached houses. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. 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.
With historic houses such as Mottisfont Abbey about 1.2 miles north-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Homes near Church of St Mary are a good example of where we look up the heritage status of the building before fixing anything to it.
Michelmersh is about 3 miles north-west of Romsey, in Hampshire. From the centre of Michelmersh to the outskirts, we cover air conditioning, from small jobs to large ones. In Hampshire alone we list 683 places, and Michelmersh is one. Guildford, roughly 43 miles off, has its own page on this site.

Aftercare tips
Simple habits make a real difference. We recommend:
- Keep the F-Gas records, commissioning details and warranty information together
- Let filters dry fully before you put them back
- Keep to the service interval the manufacturer recommends
An annual service keeps the system running efficiently, and some manufacturers make regular servicing a condition of their warranty. We’ll remind you when it’s due if you’d like.
Keep the outdoor unit clear. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.
Questions from Michelmersh
Is planning permission needed for air conditioning in Michelmersh?
It depends on the property. There’s a conservation area, the Michelmersh Conservation Area, close to central Michelmersh. 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 Michelmersh, normally Test Valley council).
Can you do air conditioning in Michelmersh?
Yes. We work across London and the South East from our base in East Grinstead, and Michelmersh is part of that. Get in touch with the details and we reply the same working day.
How much is air conditioning for one room?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork, and we fix it after a survey or from your photos.
Are you F-Gas certified?
We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
How quickly will you reply?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
How long does air conditioning installation take?
Allow a day or more, depending on the number of rooms, the pipe routes and the access. The survey tells us how long your installation will need, so you can plan around it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
