Why act early in Dorchester
Leaving a fault seldom makes it go away. A drip can turn into a damaged ceiling, and a slow leak can leave the compressor straining and early diagnosis normally keeps the repair simpler. Waiting rarely makes an air conditioning problem smaller.
Our prices page shows typical ranges, but each job is priced on what it involves. Call for a fixed-price quote, and we will talk you through it.

Air conditioning repair in Dorchester, done properly
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. If you are dealing with weak airflow from the indoor unit and drips from the indoor unit, we can sort it out.
Around Dorchester, 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.
Warranty periods vary by brand and by product. For instance, 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.

What owners can safely do
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Dorchester questions
Who do I call if my air conditioning fails in Dorchester out of hours?
Yes: ring the emergency line, day or night, from anywhere in Dorchester. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Is Dorchester in your area for air conditioning repair?
Yes, Dorchester is within the area we cover. To start, phone 07833 053749 with a few pictures.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
Is it legal to repair an R410A system?
Yes. Repairing and recharging existing R410A systems is still legal. As the GB phase-down continues, R410A is getting harder and dearer to buy and we talk through repair against replacement for older systems.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Can you repair an R22 air conditioning system?
R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. A fault that does not involve the refrigerant may still be repairable, depending on parts, but a leak usually makes replacement the sensible route. We explain the options and quote for a new system if that’s the answer.
System by system
Condensate drains and pumps
We clear the drain, test the pump and check the fall until the condensate runs away properly. If a pump has failed, we replace it and test it before we leave.
Wall-mounted split systems
The indoor and outdoor units of a split communicate through a cable. Communication faults show up as error codes, and we test the cable, the boards and the connections to find the cause.
Air conditioning repair around Dorchester

Historic England lists about 111 buildings and structures within half a mile of the centre of Dorchester, including Abbey Church of St Peter and St Paul (grade I). That only matters for replacements, where a new outdoor unit on a protected building can need consent. About 64% of households live in detached or semi-detached houses, according to the last census (2021). Tell us where your outdoor unit is and how to reach it, so we can plan the visit.
Schools such as Dorchester St Birinus Church of England School can report a fault on the 24/7 line and have non-urgent work done out of term. A photo of the error code and the unit’s rating label helps us plan the repair.

How it works
Each visit follows the same order: check the plan with you, put the dust sheets down, carry out the job, check the system and talk you through it. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. We agree a date with you and plan the visit to Dorchester so we arrive with what’s needed.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- If the repair is not worth doing, we say so and explain the options.
- Then the fix, with leaks repaired before any refrigerant is added.
- Finally, a check that it’s working and a record of what we did.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Unlock any gate, garage or side passage we need
- Clear a path to the units and the space around them

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.”
