They can be very expensive or very affordable to run. It depends on a variety of factors, a key one being the size and power efficiency of the air conditioning unit in question. A small room air conditioner or a wall-mounted one bought in the last 5 years might cost less than $100 to run all month long, even if you leave it on 24/7. Meanwhile, a central air conditioning unit that hasn’t been upgraded in years can easily rack up bills of $500 or more per month if left on all day long.
Maintenance can also have an impact on overall consumption. It’s important to have an air conditioning Kent company like this one inspect and do maintenance on the unit at least once a year to make sure everything is in order. Especially in older, bulkier units. Electrical issues and clogged filters can reduce the system’s efficiency, increasing how much electricity the unit will use.
Making sure the home is properly insulated is also helpful, as the more cold escapes the house, the harder the AC unit has to work to reach a given target temperature.
