The Most Common HVAC Mistakes Homeowners Make:

Homeowners often make simple mistakes when it comes to their HVAC systems that can lead to costly repairs and decreased efficiency.

Read on to discover the most common HVAC mistakes and how to avoid them.


Keeping your home comfortable during the summer and winter months requires a properly functioning HVAC system.

However, many homeowners make mistakes that can lead to increased energy bills, decreased efficiency, and costly repairs.

Understanding the most common HVAC mistakes can help you avoid them and ensure that your system is functioning at its best.

The Most Common HVAC Mistakes Homeowners Make

 Ignoring Regular Maintenance

One of the most common mistakes homeowners make is ignoring regular maintenance on their HVAC system. Just like a car, your HVAC system requires regular check-ups to keep it functioning properly. A certified technician can spot potential problems before they become bigger, more costly issues and ensure that your system is running as efficiently as possible.

 Improper Thermostat Settings

Another common HVAC mistake is setting the thermostat improperly. For example, turning the thermostat too low in the winter or too high in the summer will not make your home warm up or cool down faster. It will only waste energy and increase your energy bills. Additionally, programming your thermostat improperly can also lead to increased wear and tear on your HVAC system.

 Blocking Vents and Registers

Blocking vents and registers is another common mistake that homeowners make. Furniture, curtains, and even toys can block the flow of air, making it difficult for your HVAC system to effectively heat or cool your home. To avoid this, make sure that all vents and registers are clear and free of any obstructions.

 Improperly Sized HVAC System

Finally, installing an improperly sized HVAC system is a common mistake that can lead to decreased efficiency and increased energy bills.

A certified HVAC technician can help you determine the correct size for your home, taking into account factors such as square footage, insulation, and window placement.


By avoiding these common HVAC mistakes, homeowners can ensure that their HVAC system is functioning at its best, resulting in increased comfort and lower energy bills. Regular maintenance, proper thermostat settings, clear vents and registers, and properly sized HVAC systems are all important factors to keep in mind.
