The process
You don’t 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. Before we leave, the area is tidied and we explain what we’ve done. Rural lanes and tight entrances are worth mentioning before a visit to Rush Green.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure someone can let us in at the agreed time
- Clear the space around the indoor unit, or where it will go

Before you call an engineer
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749, or email if that’s easier.
Homes in Rush Green and air conditioning
The last census (2021) found about 40% of households in terraced houses. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit. At about 28 miles from central London, Rush Green sits inside the area we cover across London and the South East.
Most people start with the room that gets hottest, then add more rooms on a multi-split if needed. Knebworth House, about 2.1 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

When it’s something else
We’d rather tell you now than sell you work that won’t help, so here are the limits:
- Central heating repairs
- A ventilation problem rather than a temperature problem
- Building damp that has a structural cause
Not sure which it is? You can phone us on 07833 053749 or use the quote form and we will tell you honestly before you book.
Where we work
- Ducted systems
- Ceiling cassettes
- Air-to-air heat pumps
- Multi-split systems
- VRF systems
- Wall-mounted split systems
After we have gone
A little care keeps the system in better shape. We recommend:
- Keep the F-Gas records, commissioning details and warranty information together
- Leave space around the outdoor unit
- Have the system serviced once a year
An annual service keeps the system running efficiently, and some manufacturers make regular servicing a condition of their warranty. We can remind you when it’s due, so it doesn’t get forgotten.
Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.
Your questions about air conditioning in Rush Green
Can you do air conditioning in Rush Green?
We do: Rush Green falls inside our working area. Tell us a little about the job and we will take it from there.
How do I get a quote for air conditioning in Rush Green?
Use the quote form, or email, with a description of the job. We reply the same working day, and the quote is fixed before any work starts.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It needs space around it to breathe and room for an engineer to service it, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Does servicing affect my warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
