Where the outdoor unit goes matters to you and to the neighbours. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. We agree it with you on the survey. Booking before summer means the work in Tewin Wood is done before the hot weather.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.

Air conditioning in Tewin Wood, done properly
Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Whether you call it air con, air conditioning or an air-to-air heat pump, in Tewin Wood it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
The electrics are part of the job: a dedicated circuit where the unit needs one, certified under NICEIC, so there’s no separate electrician or building control visit to arrange.
Around Tewin Wood, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can I fit air conditioning or a heat pump 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.
What happens on the day
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes about a day for a single-room system, longer for multi-room and ducted systems. We plan the trip to Tewin Wood around you.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- 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
- Mention any roof access, ladders or high-level work
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where the consumer unit is

Advice
Common problems we fix in Tewin Wood
Not everyone is after cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, so it gives out more heat than the electricity it uses. That is how most modern split systems work.
Keep an eye out for any of the following:
- Working from home in a room that gets too warm
- A portable unit with a hose out of the window
- A loft room or top floor that bakes in summer
A loft bedroom or a glazed extension is often the room that prompts the first call.
Before you book anyone
- Whether testing, commissioning and paperwork are included
- What the manufacturer’s warranty covers and for how long
- If the figure could change on the day
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.”
