Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the condensate drained away safely.
For a home in or near Tonwell, 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.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Aftercare tips
Every system needs looking after, and most of it is easy. A few tips:
- Tell us if the unit starts to leak, rattle or show a code
- Don’t cover or box in the outdoor unit
- Refit filters properly after cleaning
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings, so you are confident using it.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.
Questions from Tonwell
Do you cover smaller places like Tonwell?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
What’s the best way to get a price for air conditioning in Tonwell?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
Do I need a new electrical circuit?
Most systems need their own 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 install and certify it as part of the job.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
Pricing air conditioning in Tonwell
You will get a fixed price before any work starts. It’s based on:
- What state the existing equipment is in
- What electrical work the job needs
- What kind of system it is
What you pay reflects the actual work. That is why every job is looked at first, and the price is agreed before we start.
What we need to know
To help us quote quickly, send us:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A photo of the consumer unit with the cover closed
- A close-up of the unit’s label showing the model number
If you need air conditioning in Tonwell, call 07833 053749. Tell us what kind of property it is and what you’d like done, plus some photos if they’re to hand. Enquiries get a reply the same working day.
How the visit works
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer, and we clear up before we go. If a lane or gateway near Tonwell is tight for a van, let us know and we will plan for it.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Mention any parking restrictions near the property
- Clear a path to the units and the space around them
- Name a contact who can meet us at the agreed time
How to get a quote
