Air source heat pumps for homes and businesses in Green Tye
We install air source heat pumps in Green Tye and across Hertfordshire, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We’ll explain which type fits your home and why. Typical jobs include checking eligibility for a heat pump grant and choosing between air-to-water and air-to-air, across radiator systems, hot water cylinders and underfloor heating.
If your home in or near Green Tye is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Homes in Green Tye and heat pumps
Central Green Tye is inside the Green Tye Conservation Area. Historic England lists about 13 buildings and structures within half a mile of the centre of Green Tye, including Bulls Cottage (grade II). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at East Hertfordshire council, which normally handles Green Tye. About 74% of households live in detached or semi-detached houses, according to the 2021 Census. Houses usually have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St Thomas, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Your questions about air source heat pumps in Green Tye
Is the heat pump grant available in Green Tye?
Green Tye is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Is Green Tye within the area you cover?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
How long does a heat pump installation take?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, and you can phone 07833 053749 or write to us at info@aircondoctor.co.uk to book it.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.

What else we do in Green Tye
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. If a lane or gateway near Green Tye is tight for a van, let us know and we will plan for it.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Mention any managing agent or landlord rules we need to follow
- Find the manual or the paperwork for the system, if you have it
- Clear the space around the indoor unit, or where it will go
Getting a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
How the job changes from property to property
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. Hot water needs a separate source, so that has to come from elsewhere.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
