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.

Home air con service cost

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, it's best to find a trusted air con specialist to get a bespoke quote to suit your needs.

How much do air conditioning unit spare parts cost?

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, costing around £100+

• A new evaporator costs £200+

• A new condenser costs £300+

• A new expansion valve costs £130 - £180

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.
