What affects the quote in Lower Slackstead
Our prices page gives typical ranges, and your quote is built on your job. What we look at:
- The equipment or parts the job needs
- One-off work versus a regular service cycle
- Whether we need access equipment for high-level work
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are not sure what’s needed, give us a ring on 07833 053749 or drop us a line and we’ll give you an honest view and a fixed price.
Before you get in touch
Good photos often save a visit. The most useful are:
- A close-up of the unit’s label showing the model number
- Wide pictures of the room or the existing unit
- The postcode and whether it’s a home, flat or business
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To get going, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
How we handle air source heat pumps in Lower Slackstead
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Common call-outs are for a boiler that’s getting old and not knowing whether a grant applies, on radiator systems, air-to-water heat pumps and homes heated by oil, LPG or gas.
Space for an outdoor unit is rarely an issue near Lower Slackstead, so the design focuses on heat loss and radiators.
Each manufacturer sets its own warranty period. 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. Whatever the brand, the manufacturer’s terms are explained on your quote.

Heat pumps in Lower Slackstead: local notes
About 45% of homes in and around Lower Slackstead date from 1945 to 1972, according to Valuation Office Agency council tax records, and Census 2021 figures found about 61% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Live in one of the older houses around Church of All Saints? Expect the survey to look closely at heat loss and at the building’s planning status. Mottisfont Abbey, roughly 4.3 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Common questions in Lower Slackstead
Is the heat pump grant available in Lower Slackstead?
Yes, if the home and the heat pump meet the scheme’s rules: Lower Slackstead is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Will a heat pump in Lower Slackstead need planning permission?
That depends on the building and where the outdoor unit goes. Around 4 listed entries sit within 0.5 miles of central Lower Slackstead. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Lower Slackstead, usually Test Valley council).
Can you come out in an emergency?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
How much time does a heat pump install need?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
What we do, step by step
Each visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Work in Lower Slackstead is booked in advance at a time that suits you.

Advice
Looking after it afterwards
Aftercare is straightforward, and it helps at the next service:
- Check eligibility for the Boiler Upgrade Scheme early
- Book a yearly service
- File the MCS certificate safely
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
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 the breaker trips a second time, leave it off and ring 07833 053749 or drop us a line.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
