How we handle air conditioning repair in Dial Post
Age alone does not decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. Typical jobs include a system that keeps cutting out and a system that runs but doesn’t cool the room, on heat pumps, multi-split systems and wall-mounted split systems.
Around Dial Post, repairs tend to be home systems, garden rooms and a few businesses. A photo of the unit’s label and a description of the fault help us plan.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What happens on the day
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. If something is different, we talk it through with you before carrying on. After that, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Somewhere like Dial Post, it helps to know about lanes, gates and where to park.
- You tell us the symptoms, the make and any error code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- We explain the cause in plain English and give you a fixed price.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- We test the system in operation and leave you a note of the fault and the fix.
How to prepare
- Keep pets and children away from the work area
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process
Getting a price
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.
Related advice
Signs you need air conditioning repair in Dial Post
Most indoor unit leaks come back to the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, and ice on the coil that melts can drip too.
These are the situations we see most often:
- A system that needs topping up again
- New noises from the system
- A system that runs but doesn’t cool the room
Weak cooling, water dripping from the indoor unit and error codes are the faults we’re called about most.

Your questions about air conditioning repair in Dial Post
Do you cover Dial Post for emergency air conditioning repairs?
The emergency line is open around the clock, and Dial Post is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.
Can you do air conditioning repair in Dial Post?
Yes. We work across London and the South East from our base in East Grinstead, and Dial Post is part of that. Get in touch with the details and we reply the same working day.
Do you protect the property while you 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.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How much is an air conditioning call-out?
Diagnosis call-outs start from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead. The cost depends on the fault, the parts and access to the units.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Dial Post and across West Sussex. Tell us who should receive the paperwork.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What affects the quote in Dial Post
The survey or diagnosis tells us what the work involves. The main factors are:
- The distance and route between the indoor and outdoor units
- What electrical work the job needs
- Which make and model is being fitted or worked on
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, call 07833 053749 or send an email, and we will talk you through it.
Before you get in touch
To speed up the quote, please include:
- A few photos of the room and the wall the unit is on, or will go on
- The rating plate or label on any existing unit
- Where the property is and what kind of building it is
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, call 07833 053749 or fill in the contact form.
Looking after your system
How well a system lasts depends on use and care. Here’s what we suggest:
- Keep the outdoor unit clear of leaves and clutter
- Never add refrigerant yourself or let anyone top up without finding the leak
- Note any error code, or take a photo of the display
After the repair, the system is run and checked in every mode it has. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind and point out anything else we spotted.
Book an annual service. A service cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small faults early and that is normally simpler than a breakdown repair.
