Haslar: your questions answered
Do you cover smaller places like Haslar?
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.
Can I fit air conditioning in Haslar without planning permission?
It depends on the property. The Stokes Bay Conservation Area is close to the centre of Haslar. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the planning department at Gosport council, typically the authority for Haslar.
Will you need to do electrical work?
Most of the time. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
Which manufacturers do you install and repair?
We install and work on the leading makes, 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 provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Can the outdoor unit go on a roof or at ground level?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We’ll tell you what to check before we fit it.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
Air conditioning installation in Haslar
Air conditioning is not only for summer: most modern splits heat too. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, and a well-chosen system can earn its keep all year round. Every installation in Haslar begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
For a home in or near Haslar, an air-to-air system can cool in summer and heat in the cooler months, which suits garden rooms, lofts and extensions that the main heating struggles with.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

When to call us in Haslar
Most overheating comes from heat gained through the day. Sunshine through glazing, especially on south and west-facing rooms, adds a lot of heat, and the heat lingers long after the sun has moved round.
It’s time to call us if you are dealing with:
- A study or office that overheats during the day
- Rooms heated by plug-in heaters
- Fans and portables that do not keep up
Bedrooms under the roof and rooms with big sunny windows are usually the first to overheat, so they’re the usual place to start.
Comparing quotes
- Whether the manufacturer’s warranty depends on regular servicing
- Who does the electrical work, and whether they can certify it
- If the quote is based on a survey, photos or a diagnosis
Managing agents and facilities teams in Haslar
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.
Facilities teams in offices, schools and public buildings book us too across Hampshire. Larger buildings can be done in stages around the people who use them.
Looking after it afterwards
To keep the system working properly:
- Keep the F-Gas records, commissioning details and warranty information together
- Tell us if the unit starts to leak, rattle or show a code
- Close windows and doors while the system is cooling
We clear up before we go: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Keep the outdoor unit clear. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.

What an install looks like in Haslar
The coast is only about 1 mile from Haslar. Salt air is hard on outdoor units, so we site them out of the worst of the sea wind where we can, and can suggest models with corrosion-protected coils where the manufacturer offers them. Valuation Office Agency council tax records put about 39% of homes in Haslar and the neighbourhoods around it before 1919, and the 2021 Census found about 43% of households in terraced houses. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. With a terrace, the back wall or an extension roof is usually the best place for the outdoor unit.
If your home is in one of the older streets near St Francis, it’s worth checking whether it’s listed or in a conservation area before an install.

What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Somewhere like Haslar, it helps to know about lanes, gates and where to park.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Name a contact who can meet us at the agreed time
- Let us know if the building has a permit or sign-in process
- Tell us about parking and loading
