5 common AC mistakes you should be aware of that can lead to higher utility bills. As temperatures rise, so does the reliance on air conditioning systems to keep homes and workplaces cool and comfortable. However, running an AC system inefficiently can lead to skyrocketing utility bills, causing unnecessary strain on your finances. Many homeowners unknowingly make mistakes that compromise the efficiency of their AC units, resulting in higher energy consumption and costs. In this blog post, we’ll delve into some of the most common AC mistakes that can lead to inflated utility bills and provide practical solutions to rectify them.

Common AC Mistakes

Being able to identify common AC mistakes is the first step to saving money in the warmer months. While some of these things might seem like common sense, they can be easy to overlook.

Neglecting Regular Maintenance:

One of the most common and costly mistakes homeowners make is neglecting regular maintenance of their air conditioning systems. Over time, dust, dirt, and debris accumulate within the unit, obstructing airflow and reducing efficiency. Additionally, worn-out components such as filters, coils, and fans can further hamper performance, causing the system to work harder and consume more energy.

Setting the Thermostat Too Low:

Setting the thermostat to an excessively low temperature in an attempt to cool the space faster is one common misconception that many make. In reality, the AC system operates at a consistent rate regardless of the temperature setting. Therefore, cranking down the thermostat will only lead to unnecessary energy consumption without achieving the desired cooling effect.

Ignoring Air Leaks:

Over time, gaps and cracks can develop in windows, doors, and ductwork, allowing cool air to escape and warm air to infiltrate the living space. This forces the AC system to work overtime to maintain the set temperature, resulting in higher energy bills. Ignoring these air leaks will not only compromise comfort but it also can put a strain on the HVAC system.

Blocking Air Vents:

Blocking or obstructing air vents with furniture, curtains, or other objects inhibits proper airflow and distribution of cool air throughout the room. As a result, the AC system must work harder to compensate for the restricted airflow, leading to increased energy consumption and reduced efficiency.

Neglecting Ceiling Fans:

Ceiling fans can complement the cooling effect of an air conditioning system by circulating air and creating a breeze that helps occupants feel cooler at higher temperatures. However, many homeowners overlook the importance of using their ceiling fans in addition to their AC units, leading to higher energy bills due to overreliance on air conditioning alone.

How to Fix Common AC Mistakes

If you’re reading through the common mistakes and realize that you’re making one or a few, don’t worry! Most of the common AC mistakes that are made can be easily fixed.

Schedule Regular Maintenance:

A key way to ensure optimal performance and efficiency of your AC unit is to schedule annual maintenance appointments with a qualified HVAC technician. During these visits, the technician will inspect, clean, and tune up your AC system, identifying and addressing the potential issues before they escalate.

Set the Thermostat Wisely:

Set your thermostat to a moderate temperature that is comfortable for occupants without overburdening the AC system. Consider investing in a programmable thermostat that allows you to adjust temperature settings based on occupancy patterns, saving energy when the space is unoccupied.

Seal Air Leaks:

Conduct a thorough inspection of your home to identify and seal any air leaks around windows, doors, and ductwork. Use weather stripping, caulking, or foam sealant to seal gaps and cracks, preventing cool air from escaping and warm air from entering.

Ensure Proper Air Ventilation:

Keep air vents unobstructed by rearranging furniture and removing barriers that restrict or obstruct the airflow. This allows for efficient distribution of cool air throughout the room, maximizing the effectiveness of your AC system.

Utilize Ceiling Fans:

Make use of ceiling fans to enhance the cooling effect of your air conditioning system. Set the fans to rotate counterclockwise in the summer to create a downdraft that circulates cool air and creates a wind-chill effect, allowing you to raise the thermostat temperature without sacrificing comfort.
