Air conditioning faults rarely improve on their own. A unit that has stopped cooling might have a refrigerant leak, a failed compressor, a blocked filter, or a faulty PCB - and each of those needs a different fix. We work on all common domestic and commercial makes, including Daikin, Mitsubishi Electric, LG, Samsung, Panasonic, and Fujitsu, as well as many older or less common systems.

When we arrive we carry out a systematic diagnostic check: inspecting the filters, checking the refrigerant pressure, testing electrical components, and reading any fault codes the system has stored. This tells us exactly what the problem is rather than replacing parts by guesswork. If a refrigerant top-up is needed, our engineers are F-Gas certified to handle refrigerant legally and safely. We carry common replacement parts on the van, which means many repairs are completed on the same visit.

Attempting DIY repairs on an air conditioning system is not advisable and, where refrigerant is involved, is illegal without F-Gas certification. Incorrect handling of refrigerant can also turn a minor fault into a compressor failure, which is a much more expensive repair. Getting a professional diagnosis early nearly always saves money in the long run.

We aim to attend repair calls in Cambridge within 24 to 48 hours on standard bookings, and we offer priority attendance for commercial customers or situations where a fault is causing significant disruption. We quote for any parts before fitting them, so there are no surprises on the invoice. For older systems where the repair cost would approach the price of a new unit, we give you an honest assessment and a quote for replacement as well so you can compare.

The most common air conditioning fault in Cambridge homes and offices is refrigerant loss due to a small leak at a pipe joint, which typically costs between £150 and £400 to locate, repair, and recharge.

Questions

Air Conditioning Repairs - common questions

What should I budget for home air conditioning in Cambridge?
Most Cambridge homeowners pay between £1,200 and £2,500 per room for a supply-and-install split-system unit. The price depends on the output size needed, the length of the pipework run, and whether any difficult wall materials such as solid brick or stone are involved. A multi-room system with a single outdoor unit costs more upfront but tends to be better value than fitting separate systems later.
How much does commercial air conditioning cost per unit in Cambridge?
Installed costs for a commercial unit in Cambridge typically run from around £1,500 for a straightforward wall-mounted split to £4,000 or more for a ceiling cassette in a busy commercial environment with complex pipework. Larger multi-zone VRF systems are priced per project following a full heat load survey. We provide a detailed written quote before any work starts.
What am I likely to pay to have my air conditioning repaired in Cambridge?
A diagnostic call-out in Cambridge typically costs between £80 and £120, which is usually applied against the repair cost. The most common fault - a refrigerant leak, regas, and joint repair - usually comes to between £150 and £400 depending on how much refrigerant is needed and how accessible the leak is. Electrical component failures such as a capacitor or PCB board vary widely in parts cost. We quote before we proceed with any repair.
Is cellar cooling expensive to install in a Cambridge pub?
A dedicated cellar cooling system for a Cambridge pub or bar typically costs between £1,500 and £3,500 installed. The main variables are the volume of the cellar, how well insulated it is, the heat load from equipment, and whether the installation involves difficult wall materials or restricted access. We provide a fixed written quote after surveying the cellar so you know exactly what to expect.
What should I budget for air conditioning installation in Cambridge?
A single split system for one room typically costs between 1,500 and 2,500 pounds installed, including all pipework and electrical connections. A multi-split system covering three or four rooms usually falls in the 3,500 to 6,500 pound range, depending on pipework complexity and the brand of unit chosen. We provide a fixed quote after a free site survey so there are no surprises.
How often should my air conditioning system be serviced?
For most domestic systems, once a year is sufficient to keep the unit running efficiently and catch any developing faults. Commercial systems - particularly those covered by F-Gas regulations - may require checks every three or six months depending on the refrigerant charge. We will advise the correct interval for your specific installation when we carry out the first visit.
Is an air source heat pump expensive to run in Cambridge?
Running costs depend on your tariff, the efficiency of your installation, and how well-insulated your home is. A heat pump in a reasonably well-insulated Cambridge property typically costs less to run than an electric boiler and, for many households, is comparable to a gas boiler on current tariffs when you account for the higher efficiency. We can model estimated running costs as part of the free survey.
How is an air curtain priced - is it the unit cost or the installation that adds up?
Both elements count, but the unit itself is usually the larger part of the total cost. A commercial air curtain for a standard doorway typically costs between 250 and 700 pounds for the unit, with installation labour adding 150 to 250 pounds in most cases. Heated models and wider or taller doorways cost more. We quote both parts separately so you can see exactly where the money is going.
