If you keep noticing an increase in your cooling costs although your AC usage remains the same, you need to schedule an inspection as soon as possible. There’s likely something wrong with your cooling system that needs professional attention. Not all cooling problems cause increases in energy bills. Knowing which ones do can help you determine what’s happening with your system and whether you need to call an HVAC technician.
Clogged Air Filters
The first thing to check is the air filter. It’s most likely located at the return air grille or somewhere near the indoor air handler. If it’s dirty, replace it so that it won’t restrict airflow. When this happens, it makes the AC work harder to keep the home comfortable, consuming more energy and driving up your cooling costs. While you can change the filter on your own, you can ask a technician for help if you feel the need.
Dirty Coils
Most air conditioner setups have two coils: an evaporator coil and a condenser coil. The former is on the indoor part of the system, and the other is on the outdoor unit. Over time, these coils can accumulate buildup from dust, dirt, and other contaminants that impacts their heat transfer process. The AC may run longer cycles in an attempt to keep the home at the temperature set on the thermostat, resulting in higher energy bills. Have the coils cleaned at least once a year as part of preventive maintenance to keep this from happening.
Poorly Insulated Ductwork
As conditioned air flows through your ductwork, some of it will naturally escape through small gaps and poorly sealed connections. The farther away a room is from the indoor air handler, the more air loss is likely to affect it. This is why it’s so important to give the ductwork adequate insulation. The AC won’t have to run as long to make up for the loss of cooling because more of the conditioned air will reach the intended rooms.
Low Refrigerant
Refrigerant plays a key role in the cooling system’s ability to efficiently absorb heat and lower the indoor temperature. When the refrigerant is low, the system will use more energy and run longer than normal to keep the home comfortable. Unlike fuel for a vehicle, refrigerant doesn’t get used up over time. It can only run low if the cooling equipment develops a leak. You need to have the leak repaired so that the problem doesn’t keep happening.
These are just a few of the many air conditioner problems that can make your cooling costs more expensive. If you replace the air filter and keep the air vents open and unobstructed, but your cooling costs are still too high, call a licensed technician for an inspection.
