Looking after your system
After the visit, a few habits help:
- Use the settings explained at handover
- Check eligibility for the Boiler Upgrade Scheme early
- Leave space around the outdoor unit
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
About our air source heat pumps in Hearnden Green
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. The work covers hot water cylinders, underfloor heating and air-to-air heat pumps, and the jobs we see most are no space for a hot water cylinder and checking whether planning permission is needed.
In a place like Hearnden Green, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. We agree a date with you and plan the visit to Hearnden Green so we arrive with what’s needed.
- We talk through your home, your current heating and what you want from a heat pump.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Have the make and model of any existing unit to hand
- Tell us about parking and loading
Getting a quote
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.

Homes in Hearnden Green and heat pumps
About 32% of homes in Hearnden Green and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and Census 2021 figures found about 74% of households in detached or semi-detached houses. Newer homes usually lose less heat, which tends to suit a heat pump well. Houses usually have space for an outdoor unit and a hot water cylinder.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. If your home is listed, like Leeds Castle about 4.1 miles north, listed building consent comes before any heat pump work.

What affects the cost of air source heat pumps
Typical ranges are on our prices page, but every job is priced on its own. The quote depends on:
- What state the existing equipment is in
- The equipment or parts the job needs
- How many units are involved
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
What to send for a quote
When you call or email, it’s useful to have:
- A close-up of the unit’s label showing the model number
- The outside wall, roof or yard where the outdoor unit sits or would go
- A photo of the consumer unit with the cover closed
Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.
Hearnden Green: your questions answered
Do I need planning permission for a heat pump in Hearnden Green?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 12 buildings and structures within half a mile of the centre of Hearnden Green. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Maidstone council, normally the authority for Hearnden Green.
Can I get the Boiler Upgrade Scheme grant in Hearnden Green?
Yes, the scheme covers homes in England, including Hearnden Green, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we’re MCS certified.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Are my radiators big enough for a heat pump?
That depends on the room’s heat loss and the radiator’s size. We check them all during the survey, so the quote covers any changes.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
