How much does a home air con service cost?

Wondering how much a home or office air con service costs? Whether you're looking to improve the airflow in your home or office, this guide will help you to budget for the costs involved.

Regular servicing of your home or office air con unit will make sure your air conditioning is fully functional when summer arrives.

It’ll help to make sure the unit is working at its optimum efficiency while reducing electricity bills. This is because clogged air filters, dirty condenser coils, and other impurities force the air con unit to work harder to perform, therefore using more energy.

An office or home air conditioning service cost comes in at around £70 - £120 per unit. The cost largely depends on the size of the units and your location in the UK.

Depending on how much the AC is used, it could be more cost-effective to arrange for a monthly air con service cost with your chosen company. This will cover you in case the unit ever breaks down and you need an emergency repair.

Prices for a monthly air con maintenance agreement usually start around £40+ per month.

Unless you’re qualified and experienced in handling air con repair, we recommend you find a trusted air con specialist to get a bespoke quote to suit your needs.

An air conditioning engineer will normally charge between £30 - £60 per hour to service or regas an air conditioning unit.

You will also be charged for the cost of the refrigerant required, which could be between £35 - £130.

If you’re based in London or the South East you can expect to pay a higher rate.

Air con service cost calculator

When getting your air con unit serviced or regassed, the total cost will be dependent on:

  • The labour charge plus any call-out fee
  • The cost of any new refrigerant
  • Any new parts that may be required to bring your unit back to full working order

You may also need to pay for any additional services including cleaning or antibacterial treatment which can cost in the region of £15 - £30.

Air conditioning spare parts

There are four main parts to an air conditioning unit: the evaporator, the condenser, the compressor, and the expansion valve. The most expensive part to repair or replace is the air compressor. Depending on the age of the air con unit, it might be worth considering replacing the AC unit altogether. Generally, it’s recommended this is done every 10-15 years.

Other parts, such as the air filters, are much cheaper to replace. This should be done at least six times a year to keep the air clean, especially if you have pets.

The benefits of an air con service are that the unit will perform more efficiently, and any problems will be spotted early, which could save you money in the long run.
