Homes in Green Street and heat pumps
About 57% of homes in Green Street and the neighbourhoods around it date from 1945 to 1972, according to Valuation Office Agency council tax records. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Green Street is about 14 miles from central London, well within the area we cover from our base in East Grinstead.
Historic houses such as Wyllyotts Manor, about 3.7 miles north-east, are a reminder that listed homes need consent before a heat pump goes in. Live in one of the older houses around St Michael and All Angels Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Air source heat pumps in Green Street
We install air source heat pumps in Green Street and across Hertfordshire, and we are 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 will explain which type fits your home and why. The work covers homes heated by oil, LPG or gas, radiator systems and air-to-air heat pumps, and the jobs we see most are not knowing whether a grant applies and choosing between air-to-water and air-to-air.
Space for an outdoor unit is rarely an issue near Green Street, so the design focuses on heat loss and radiators.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

What affects the cost of air source heat pumps
A fixed price needs a few facts first. We check:
- Whether it’s a one-off job or part of a maintenance contract
- How many units are involved
- The brand, model and parts involved
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before any work starts, so you know where you stand.
What we need to know
You don’t need the technical terms. It helps if you can send:
- The address and the type of property
- The outdoor side of the property, including any roof or flat area
- The remote or wall controller showing any error
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price so you know the cost before we begin.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Rural lanes and tight entrances are worth mentioning before a visit to Green Street.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Let us know where we can park and unload
- Mention any roof access, ladders or high-level work
- Make sure someone can let us in at the agreed time

What you can do yourself, and what needs us
Some faults have simple causes you can check first: 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 write to us at info@aircondoctor.co.uk.
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. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Green Street questions
Does the Boiler Upgrade Scheme cover homes in Green Street?
Green Street is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Is Green Street in your area for air source heat pumps?
We do: Green Street falls inside our working area. To start, give us a ring on 07833 053749 or email us with a few photos.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for example, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. Both are part of what we install.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
Why it’s worth doing now in Green Street
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for while the old heating still works. Getting the date in early helps for a place like Green Street.
Our prices page shows typical ranges, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll explain what it covers.
