Air conditioning in RM3: how it works
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. Common call-outs are for a loft conversion that’s too warm to use and not knowing which system, size or brand to choose, on ducted systems, VRF systems and multi-split systems.
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 the rest is down to us. At the end, we tidy up and run through the work with you.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- 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.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.

Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, call 07833 053749 or fill in the contact form.

Air conditioning around RM3
Across RM3, from Harold Wood, Gallows Corner and Harold Park to the villages, homes range from older terraces and cottages to new estates and flats. Each install starts with a survey of the rooms, the walls and where the outdoor unit can go, then a fixed-price quote.
London and the South East cover everything from city flats to rural cottages. Our work is F-Gas certified, NICEIC approved for the electrics and MCS certified for heat pumps.
Harold Wood: Plenty of people near Harold Wood station split the week between the train and a spare room, and that spare room is often the first to get a unit. With historic houses such as Hare Hall about 1 mile south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
When something else is needed
In fairness, some problems need a different answer:
- Draughts and missing insulation
- Gas boiler or central heating faults (we do not work on gas boilers)
- Damp from leaks or a lack of ventilation
Fixed-price quotes for air conditioning in RM3
Your quote is based on your property. We consider:
- The equipment or parts the job needs
- The type of system, from a single split to a larger system
- The pipe route between the units
- A single visit or a regular plan
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before any work starts, and the quote sets out the VAT.
What to send for a quote
Simple jobs can often be priced from photos and some basics. Useful things to send:
- The outdoor side of the property, including any roof or flat area
- The postcode and whether it’s a home, flat or business
- A short video of any fault, such as a noise or a flashing light
- Photos showing the indoor unit and the space around it
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Signs you need air conditioning
Some people come to us for heating rather than cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. That is how most modern split systems work.
Common reasons people call us include:
- Rooms under the roof that stay hot into the night
- Working from home in a room that gets too warm
- An ageing air conditioning system near the end of its life
- Old electric heaters you’d like to replace with something more efficient
Let and managed properties
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed-price quote.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.
Common questions in RM3
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Will I need planning permission?
Not always. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas and the survey picks it up. This is general information, not legal advice.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Where does the outdoor unit go?
We agree it with you on the survey. It needs space around it to breathe and room for an engineer to service it, and a position facing a road can bring extra planning considerations. We will tell you what to check before we fit it.
How long does it take to fit air conditioning?
A single-room system is typically fitted in a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
How much is air conditioning for one room?
For one room, a split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. The price is fixed before we start.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
