Air conditioning servicing for homes and businesses in Heronsgate
For homes with one or two units and businesses with many, we can set up a maintenance contract. The visits, the scope and the cost are fixed with your quote, so the system is looked after on a regular schedule. The work covers ceiling cassettes, air-to-air heat pumps and multi-split systems, and common reasons people get in touch are leak check records that need bringing up to date and an unpleasant odour when the system runs.
Around Heronsgate, outdoor units sit close to gardens and greenery, where seeds and leaves collect on the coil. A yearly clean keeps the system working well.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Owner checks or an engineer?
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 escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.

What affects the cost of air conditioning servicing
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- Whether we need access equipment for high-level work
- A single visit or a regular plan
- What we find on the survey or diagnosis
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Helping us quote
Good photos often save a visit. The most useful are:
- A photo of the consumer unit with the cover closed
- The outdoor side of the property, including any roof or flat area
- Any error code or flashing light on the display
For a fixed-price quote, give us a ring on 07833 053749 or email us and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.
Heronsgate: your questions answered
Do you cover Heronsgate for air conditioning servicing?
Yes. Heronsgate is one of the places we cover. Just ring us on 07833 053749 with a few details.
How often should air conditioning in Heronsgate be serviced?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
How much time does an air con service need?
It takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. The number of indoor units and how easy they are to reach make the biggest difference so we’ll confirm the time when we book.
Do I need a service to keep the manufacturer’s warranty?
Warranty terms are set by the manufacturer, not by us. Read the conditions for your brand, as they may include servicing, and keep each service record with the warranty paperwork.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Is a regas part of an air conditioning service?
A service doesn’t include adding refrigerant. If a system has lost refrigerant, it has leaked from somewhere. Where the checks point to a leak, we explain the options for finding and fixing it.
Keeping systems in Heronsgate running
Central Heronsgate is inside the Heronsgate Conservation Area. Draw a one-mile circle round the middle of Heronsgate and it takes in 3 conservation areas. Historic England lists about 5 buildings and structures within half a mile of the centre of Heronsgate, including Laurel Cottage and Crowthorne (grade II). That only matters for replacements, where a new outdoor unit on a protected building can need consent. About 46% of homes in Heronsgate and the neighbourhoods around it date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 75% of households live in detached or semi-detached houses, according to Census 2021 figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
For a school like Chorleywood Primary School, maintenance visits can be booked out of term. Spring is a good time for a service, before the system is needed for cooling.

The process
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Visits to Heronsgate are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We start with the details of the system and anything you’ve noticed.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- Electrical connections, controls and refrigerant performance are tested.
- We explain what we found and price any repair before it’s done.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Mention any parking restrictions near the property
- Clear access to the fuse board

How the job changes from property to property
Wall-mounted, ducted and cassette units
Wall-mounted units are the most common indoor unit in homes. They open up for the filters, coil and fan to be cleaned and the drain is cleared at the same visit.
Refrigerant performance and leak checks
tCO2e is the refrigerant charge in kg multiplied by its global warming potential, divided by 1,000. So 3 kg of R32 is roughly 2.0 tCO2e, and the same amount of R410A is roughly 6.3 tCO2e. We read the charge from the unit’s label and work it out for you.

“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.”
