Why is your electricity bill so high?

If your electricity bill keeps rising, your air conditioner is one place to look. Dirty filters, coils, and fan components can reduce cooling performance and make the system run longer. Weather, thermostat settings, usage, and electricity rates also affect the total.

How Dirt Affects Cooling

Wall-mounted split systems, window units, cassette units, and ducted systems all move heat out of the indoor space. Air passes through a filter and across the indoor coil, where it is cooled before returning to the room.

Filters do not catch every particle. Over time, dust can collect on the coil and blower. Moisture on the cooling coil can also support buildup when the system is not kept clean.

As dirt restricts airflow and heat transfer, the system may struggle to maintain the desired temperature. Cleaning the filters alone may not resolve buildup deeper inside the unit.

Planning Regular Maintenance

An appropriate maintenance schedule depends on how much the system runs and the conditions around it. In Guam, year-round use, humidity, dust, and salt air can make regular inspections especially useful.

AEL&L can inspect and clean your system and help identify the reasons for poor performance. See our current cleaning prices.
