HVAC Mistakes That Will Cost a Homeowner in Summer

Check out some helpful tips on avoiding costly HVAC mistakes during the hot months.

Utility bills always go up in the summer due to the increased use of the HVAC unit. However, most homeowners might not be aware that there are steps they can take to lower these costs. Learning to curb a few bad habits could significantly affect the monthly energy bills.

Check out some helpful tips on avoiding costly HVAC mistakes during the hot months.

Neglecting regular maintenance of the unit

A typical mistake contributing to cooling costs is not maintaining the HVAC unit. This can cause appliances to run longer and work harder, making them more inefficient. Most air conditioning manufacturers recommend that customers have their units professionally checked and maintained before the summer season begins. But they should also carry out a second inspection in the fall. This will ensure that their system is still running smoothly after grueling summer use.

It's essential to schedule these routine maintenance checks with an experienced technician. This will prevent homeowners from forgetting about the HVAC unit until it develops a problem.

Not changing air filters

The air conditioner's internal coils need continuous airflow to function correctly. If they are blocked with dust and grime, they will no longer be able to provide adequate cooling to the home. Therefore, changing them at the start of the season is recommended. This routine task will help keep the appliance running efficiently and reduce cooling costs. Note that it's important to source high-quality filters that will last through the season.

Using an oversized HVAC unit

Contrary to popular belief, a bigger HVAC doesn't necessarily mean improved cooling performance. Replacing an existing unit with one the same size can be a big problem. Many homeowners might not realize that a 20-year-old unit isn't nearly as powerful as a modern one of the same size. Talk to a skilled HVAC technician when purchasing a new unit to ensure it's the right size for the home.

When an oversized unit is used, it tends to cool the home's interior too quickly, which can lead to higher humidity levels. This is an issue that affects the comfort levels of the house. A suitably sized air conditioning system can help keep occupants comfortable as it will run long enough to remove moisture from the air. In addition, an efficiently running unit will require less energy and result in lower energy bills.

Ask a technician to perform a residential load calculation to determine the optimal size of an air conditioning system. This process involves analyzing the various factors that affect the home's temperature needs, such as the square footage, the number of windows, and the construction method.

Set the stage for a cool summer!

The HVAC unit is an essential home appliance, especially in the summer. However, to ensure that it's functioning optimally, it's crucial to consult a skilled technician to perform routine maintenance on the unit.
