Tyttenhanger air source heat pumps
We cover Tyttenhanger for air source heat pumps. A look at the job first, a fixed-price quote and written records at the end.
- Not knowing whether a grant applies
- No space for a hot water cylinder
- Plans to switch to electric heating with a heat pump
Safe owner checks
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. 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 Tyttenhanger
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Guesswork leads to systems that are too big or too small. If the problem is wanting to stop using oil, LPG or gas for heating and an oil, LPG or gas boiler near the end of its life, we can sort it out.
Space for an outdoor unit is rarely an issue near Tyttenhanger, so the design focuses on heat loss and radiators.
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.

Do you need air source heat pumps in Tyttenhanger?
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
If any of these sounds familiar, it’s worth a diagnosis:
- Finding a place for the outdoor unit
- Planning and permitted development questions
- Not knowing whether a grant applies
Batchwood Hall, roughly 3.3 miles north-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

How it works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a village like Tyttenhanger, tell us about narrow lanes, gates and parking when you book.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
How to prepare
- Keep pets out of the rooms we’re working in
- Tell us about any building rules, permits or sign-in
- Make sure we can reach the consumer unit or fuse board
Getting a quote
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Then ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Questions from Tyttenhanger
Can you do air source heat pumps in Tyttenhanger?
Yes. Tyttenhanger is one of the places we cover. Just phone us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Is Tyttenhanger within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. The final price depends on the heat loss survey, the radiators and the cylinder and the quote is fixed.
Can you come out in an emergency?
Yes, any time. 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.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
When something else is needed
To be straight with you, there are a few things this work won’t fix:
- Tax advice on your own circumstances
- A grant for a home that does not meet the scheme rules
- Any gas work on the existing boiler
If you are not sure, just phone us on 07833 053749 or drop us a line and we will give you a straight answer.

A customer’s words
“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.”
