Air con installers in Hammerwood
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across West Sussex.
For a home in or near Hammerwood, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating does not reach well, such as a garden room or loft.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

What happens if it’s left?
For homeowners, timing can matter for VAT: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. Whether a particular system qualifies depends on the facts, so we confirm the VAT on your quote. This is general information, not tax advice. Dealing with it now is normally simpler than a breakdown later.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, give us a ring on 07833 053749 or fill in the contact form for straight advice and a fixed price.

Air conditioning in Hammerwood: the local picture
The last census (2021) found about 64% 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 your home is in one of the older streets near Church of St Stephen, it’s worth checking whether it’s listed or in a conservation area before an install. With historic houses such as Hammerwood Park about 0.8 miles south-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Pricing air conditioning in Hammerwood
Every job gets its own quote. These are the things that affect it:
- What state the existing equipment is in
- The equipment or parts the job needs
- The electrical supply and whether a new circuit is needed
The cost depends on the system and the number of rooms or units, the access and the parts and time the job needs. You get a fixed price before we start, so you know where you stand.
Helping us quote
When you contact us, these details help:
- Your consumer unit or fuse board
- The postcode and whether it’s a home, flat or business
- A close-up of the unit’s label showing the model number
Need a price for air conditioning? Please ring us on 07833 053749 or fill in the contact form with a few details about the property. We’ll talk you through the options and give you a fixed-price quote before anything is booked.
After we have gone
Simple habits make a real difference. Our advice:
- Tell us if the unit starts to leak, rattle or show a code
- Keep the indoor unit’s filters clean
- Do not cover or box in the outdoor unit
Questions after the installation go to the same number. Tell us what the system is doing, and any code on the display, and we will talk it through with you.
Regular filter cleaning is the simplest thing you can do. Blocked filters cut airflow and make the system work harder, so it uses less electricity for the same comfort.

How the visit works
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. A note on how to find the property and where to park makes a visit to Hammerwood easier.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Let us know where we can park and unload
- Keep pets and children away from the work area

Advice
Hammerwood questions
Do you cover Hammerwood for air conditioning?
Yes, Hammerwood is within the area we cover. Just ring us on 07833 053749 or drop us a line with a few details.
Will air conditioning in Hammerwood need planning permission?
It depends on the property. Historic England lists about 6 buildings and structures within half a mile of the centre of Hammerwood. 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 local planning authority (for Hammerwood, normally Mid Sussex council).
Does air conditioning work as heating?
Typically, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
