Air Conditioning Service and Repair London

Air conditioning service and repair in London

Climate Flow Limited carries out air conditioning service and air conditioning repair in London and surrounding areas, for homes and for commercial sites such as shops, offices, restaurants and gyms. Our engineers are F-Gas certified and work on split, multi-split, ducted, cassette and VRF/VRV systems. An air conditioning service is a planned visit where an engineer cleans, checks and tests a system so it keeps running as designed. A repair finds and fixes a fault once something has gone wrong.

What does an air conditioning service include?

A typical air conditioning service checks:

• The refrigerant circuit: joints and pipework checked for signs of a leak

Manufacturers describe the same kind of health check. Mitsubishi Electric's own maintenance programme includes auditing refrigerant levels with diagnostic software, and the manufacturer says regular servicing can help avoid larger repairs.

How a service visit runs

1. Ask about the system. What it serves, any faults the site has noticed and any error codes on the controller.
2. Inspect and clean. The indoor and outdoor units.
3. Check the refrigerant circuit. Look for signs of a leak on joints and pipework.
4. Run and test. Turn the system on and check that it runs.
5. Record and report. Write up what was found, what was done and anything that needs a repair.

Common air conditioning faults we repair

Each of these faults has more than one possible cause, which is why an engineer tests the system before replacing parts.

• Not cooling or not heating.
• Water leaking from the indoor unit.
• Ice on the pipework or indoor coil.
• Error codes or the unit shutting down. The controller is reporting a fault that the engineer reads and traces.
• New noises or smells.

What are the F gas rules for air conditioning?

Under UK rules, the person who operates equipment containing F gas (fluorinated gas) above the threshold is responsible for getting it checked for leaks. How often depends on how much refrigerant the system holds, measured in tonnes of CO2 equivalent:

• 5 to less than 50 tonnes of CO2 equivalent: at least once every 12 months.
• 50 to less than 500 tonnes of CO2 equivalent: at least once every 6 months. Automatic leak detection can extend the interval.

Which band a system falls into depends on its refrigerant type and charge; an engineer works it out from the nameplate. If a check finds a leak, it must be repaired as soon as possible and the system re-tested within a month to confirm the repair worked. Records of the charge, gas added, leak checks and recovery must be kept for 5 years for equipment containing F gas equivalent to 5 tonnes or more of CO2.

The law also says who may do the work. Engineers need their own F gas qualifications to install, service and maintain air conditioning and check it for leaks, and working with F gas without them is against the law. A company servicing equipment that others operate must also be certified for that work. Climate Flow is F-Gas certified.

Is a TM44 inspection the same as an air conditioning service?

No. In England and Wales, air conditioning systems with an effective rated output of more than 12kW must be inspected regularly by an energy assessor, with inspections no more than five years apart. It is called a TM44 inspection because the government guidance draws on the CIBSE TM44 methodology. The assessor must be a current member of an accreditation scheme. The inspection is separate from the routine service and leak checks an engineer carries out, and both may apply to the same system.

Which systems and sites we service

A split system is one indoor unit connected to one outdoor unit; a multi-split runs several indoor units from one outdoor unit. A cassette unit is an indoor unit set into the ceiling. A ducted system hides the indoor unit above the ceiling and sends air through ducts to grilles. VRF (variable refrigerant flow), also called VRV, runs many indoor units from one or more outdoor units. We install and service Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Toshiba, Panasonic and Samsung systems.

We service air conditioning in homes, retail units, offices, restaurants and gyms. At Energie Fitness Gym, Climate Flow carried out maintenance on a Mitsubishi Electric VRF system.

Where a site needs new equipment rather than a repair, see the cassette air conditioning installation for a restaurant on Orsman Road. Our full list of services covers commercial refrigeration and domestic heating as well as air conditioning.
