What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
On air conditioning, the filters in the indoor unit are normally 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.
How we handle air source heat pumps in Calvert
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. If you’re dealing with finding a place for the outdoor unit and moving away from fossil-fuel heating, we can sort it out.
Homes around Calvert normally have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Why deal with it now?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions. We explain which makes sense for you. A dirty or faulty system works harder and costs more to run.
What you pay depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before we start, so there are no surprises.

What the work involves, system by system
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.
The Boiler Upgrade Scheme
Not every home qualifies, so we check before you commit.

What else we do in Calvert
How it works
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 we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that 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. Somewhere like Calvert, it helps to know about lanes, gates and where to park.
- It begins with your house and the heating it relies on now.

Some jobs can be priced from photos, while others need a survey. 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.

Your questions about air source heat pumps in Calvert
Can you do air source heat pumps in Calvert?
Yes, Calvert is within the area we cover. Just give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Will you come out to Calvert?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. We install both types.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Which manufacturers do you install and repair?
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 explain why.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.
What a heat pump looks like in Calvert
At about 48 miles from central London, Calvert sits inside the area we cover across London and the South East. About 32% of homes in the Calvert area have been built since 2000, according to Valuation Office Agency council tax records, and about 79% of households live in detached or semi-detached houses, according to the 2021 Census. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Claydon House, roughly 2.1 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. If your home is one of the older properties near Church of St Michael, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
