How we handle air conditioning servicing in Cassiobury
We’re asked to service systems for many different reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. The same full set of checks applies whatever prompted the call. If you’re dealing with condensate leaking into the room and systems that need a 6 or 12-monthly leak check, we can sort it out.
In a place like Cassiobury, the outdoor unit often sits near a garden, hedge or trees, so the outdoor coil can clog with leaves and seeds. Every service includes cleaning it.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Your questions about air conditioning servicing in Cassiobury
Can you do air conditioning servicing in Cassiobury?
Yes, Cassiobury is within the area we cover. Get in touch with the details and we reply the same working day.
Does my air con in Cassiobury need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Is there a survey before the work?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
Is a regas part of an air conditioning service?
The service checks how the refrigerant circuit is performing, but does not include adding gas. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Does the manufacturer’s warranty require regular servicing?
Each manufacturer sets its own terms. Some warranties may include conditions about regular servicing so it’s worth reading yours. We’re happy to go through them with you, and our service record shows the work was done.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.

After we have gone
Looking after it is simple, and it makes the next visit easier:
- Keep to an annual service, or more often if needed
- Clear leaves and debris from around the outdoor unit
- Report drips, smells or noises early
Where the system needs F-gas leak checks, the result is recorded, and the next check is due within the period the rules set. We can diary it for you.
The single most useful thing you can do is keep the filters clean. On many wall-mounted units, the filters lift out easily and the user manual explains how often.
The process
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can typically work room by room or zone by zone. The work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Everything the job in Cassiobury needs is worked out beforehand.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- On arrival, a quick performance check shows how well it’s working before the clean.
- We clean the filters and coils and make sure the condensate drains away.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- A service record follows, with any faults and the options for fixing them.
Getting ready for the visit
- Have the make and model of any existing unit to hand
- Make sure we can reach the outdoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board

How we price air conditioning servicing
Typical ranges are on our prices page, but every job is priced on its own. The quote depends on:
- How easy the units are to reach
- One-off work versus a regular service cycle
- Whether it’s a simple split or a larger system
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- The outdoor side of the property, including any roof or flat area
- Your consumer unit or fuse board
- A few photos of the room and the wall the unit is on, or will go on
For a fixed-price quote, call 07833 053749 or fill in the contact form and tell us about the property and what you need. A few photos make it quicker. You’ll hear back from us the same working day.
