- A room that is unbearable on warm days
- A business premises that overheats in summer
- Rooms under the roof that stay hot into the night
When to call us in Hammer
Rooms in the roof are often the hardest to keep cool. Heat comes in through the roof and rises from the rest of the building, which is why a loft bedroom can still be warm at bedtime.
Reasons to give us a call include:
- A home office that warms up with screens and equipment
- An office, shop or restaurant that’s uncomfortable for staff and customers
- Uncertainty over the right type and size of system
Around St. Stephen's Church, a quick check of the listing and conservation maps is part of planning any install.

Air conditioning for homes and businesses in Hammer
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. If you want air conditioning in Hammer, you get one team and one number from survey to sign-off.
Many installs in Hammer can go ahead as permitted development, but listed buildings, conservation areas and flats often need consent first: we tell you at the survey if it applies.
Space outside is rarely the problem in a place like Hammer. 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, ready for the next service or a warranty query.

Common questions in Hammer
Do you cover Hammer for air conditioning?
We do: Hammer falls inside our working area. Tell us a little about the job and we’ll take it from there.
Is air conditioning in Hammer permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The River Wey Conservation Area is close to the centre of Hammer. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with Waverley council, which is usually the planning authority for Hammer.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Should I choose wall-mounted, ducted or cassette?
It depends on the rooms and the building. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes anything from a day for one room to several days for a multi-room or ducted system, and we tidy up before we leave. Seeing the property in pictures first means the trip to Hammer can be planned properly.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Clear the space around the indoor unit, or where it will go
- Dig out any previous service or F-Gas records

VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, phone 07833 053749 or email us.

What the work involves, system by system
Multi-split systems
With a multi-split, one outdoor unit serves two or more rooms. It saves wall space outside and suits homes where several rooms need cooling and each indoor unit has its own controls.
Offices, shops and commercial rooms
Offices and shops normally need several units and sensible central controls. We size for the people, equipment and glazing in the space, and plan the work so the business keeps running.
What affects the quote in Hammer
We quote each job individually. These are the things that affect it:
- The electrical supply and whether a new circuit is needed
- The distance and route between the indoor and outdoor units
- How easy the units are to reach
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote and give you a fixed price before we start.
Asking for a quote
When you call or email, these details help:
- The outdoor side of the property, including any roof or flat area
- A photo of the consumer unit with the cover closed
- The address and the type of property
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.
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.”
