Air conditioning installation in Todd's Green
Our engineers work in Todd's Green on air conditioning. A look at the job first, a fixed-price quote and written records at the end.
- A system on old refrigerant that is due for replacement
- An office, shop or restaurant that is uncomfortable for staff and customers
- Rooms that get too hot to sleep or work in
How the visit works
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, test what we have done and explain it all to you. On site, the work takes anything from a day for one room to several days for a multi-room or ducted system. If a lane or gateway near Todd's Green is tight for a van, let us know and we will plan for it.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about parking and loading
- Dig out any previous service or F-Gas records

Air conditioning for homes and businesses in Todd's Green
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and as NICEIC approved contractors we can install and certify it as part of the job. A lot of the calls we get from Todd's Green are about one room that is too hot to sleep or work in. That’s typically a single wall-mounted split, from £1,200 + VAT.
New circuits are done by our NICEIC approved electricians, so the electrical paperwork comes with the installation.
For a home in or near Todd's Green, 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.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Do you need air conditioning in Todd's Green?
Most overheating comes from heat gained through the day. Sunshine through glazing, especially on south and west-facing rooms, adds a lot of heat, and once the room has warmed up, it holds on to it into the evening.
The things we’re asked about most are:
- Old electric heaters you’d like to replace with something more efficient
- A business premises that overheats in summer
- Rooms under the roof that stay hot into the night
Around Church of St Mary the Virgin, a quick check of the listing and conservation maps is part of planning any install.
What your quote should include
- Whether the price is fixed or an estimate
- What records you get at the end
- Whose warranty applies, and on what terms
Rented and managed buildings
Keeping records across a portfolio is half the battle. Every visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Air conditioning around Todd's Green
About 40% of households live in terraced houses, according to the 2021 Census. Terraces have little side access, so the outdoor unit normally goes on the rear wall or a flat roof, with the pipe run kept short.
Knebworth House, about 3.5 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

What else we do in Todd's Green
Todd's Green: your questions answered
Do you cover smaller places like Todd's Green?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Is planning permission needed for air conditioning in Todd's Green?
It comes down to the building and the spot chosen for the outdoor unit. Around 10 listed entries sit within 0.5 miles of central Todd's Green. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the planning department at Stevenage council, usually the authority for Todd's Green.
How long will the installation take?
It takes about a day for a single-room system, longer for multi-room and ducted systems. We confirm the time when we quote so there are no surprises.
How do you size the system?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Keep every service record either way.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
From one of our customers
“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.”
