Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.

Outdoor units around Denvilles often sit on the ground or a low wall bracket at the back of the house, where it’s out of sight from the road and easy to service.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

After we’ve gone
Once we have finished, these simple steps help:
- Keep the room closed while it runs
- Keep the outdoor unit clear of leaves, plants and clutter
- Keep the handover documents somewhere safe
Questions after the installation go to the same number. Let us know what’s happening and any error code, and we’ll talk it through with you.
Keep the outdoor unit clear. Leaves, plants, bins and stored items around it restrict the airflow, and the system has to work harder as a result.
Common problems we fix in Denvilles
Computers, screens, lighting and people all give off heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even when it is not especially hot outside.
Customers usually contact us after spotting one of these:
- A system on old refrigerant that’s due for replacement
- An office, shop or restaurant that is uncomfortable for staff and customers
- Rooms heated by plug-in heaters
Older streets near St Thomas à Becket Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.

Your questions about air conditioning in Denvilles
Does being near the sea make a difference to air conditioning in Denvilles?
It can, as Denvilles is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Is Denvilles within the area you cover?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Do you provide F-Gas records?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
How it works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. Send pictures of the space and the outside wall, and we can plan the work near Denvilles.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Mention any roof access, ladders or high-level work
- Tell us about parking and loading
- Mention any managing agent or landlord rules we need to follow

Air conditioning around Denvilles
The coast is only about 1 mile from Denvilles. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we will tell you if the model you choose has that option. There are 3 conservation areas within a mile of the centre of Denvilles. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Warblington Secondary School (grade II). Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, Havant council, typically the planning authority here has the final say on what’s allowed. Census 2021 figures found about 61% 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.
If you commute from Warblington station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed.
