6 Signs Your HVAC System is Too Big or Too Small for Your Home

Having an improperly sized HVAC system can lead to problems that lower your indoor air quality and comfort. If your system is too big or too small, you’ll end up wasting energy and money when heating or cooling your home. Here are six signs the HVAC system in your Hillsborough, NC, home is too big or too small:

Inconsistent Temperatures

When your HVAC system is too small, it’ll lack the capacity to cool or heat your home. This can lead to inconsistent temperatures and cold and hot spots.

Hot and cold spots can encourage the growth of biological contaminants in your home. They also lead to discomfort as a result of drastic temperature changes. A qualified service tech can help determine the appropriate size of HVAC system to install in your home.

Short-Cycling

An oversized system cools and heats your home within a short period and reaches the set temperature before it completes the full cycle. This will cause the system to keep turning on and off. Short-cycling can increase the wear and tear of your HVAC system and lower its efficiency.

Humidity Issues

Your HVAC system helps to control humidity in your home. If your system is too big, it’ll short-cycle and turn off before properly regulating humidity. If your system fails to run long enough, water vapor in it may evaporate into your indoor air.

On the other hand, if your system is too small, it won’t be able to control humidity in your entire home. Too much humidity in your home can encourage the growth of biological pollutants and lead to increased condensation. A service tech should inspect your home and calculate the square footage and consider other factors like ductwork design to ensure your system is the appropriate size.

High Energy Bills

If your air conditioner is too small, it’ll take longer to cool or heat your home. Your system ends up consuming more energy leading to higher cooling and heating bills. High energy consumption also increases your carbon footprint, which has negative effects on the environment.

An oversized system can also increase your energy bills because it keeps turning on and off. If you notice your energy bills are higher than local averages, you may have an improperly sized system.

Frequent Breakdowns

If your HVAC system is too small, it’ll strain and overwork to cool or heat your home. This increases wear and tear on the components, leading to frequent breakdowns. Your system will end up costing you more money with frequent repairs.

Frequent breakdowns lower the efficiency of your system and shorten its service lifespan. Eventually, you may have to replace your entire system with a new one. If you notice your system keeps breaking down, you may have to call an experienced service tech to check whether it’s properly sized.

Reduced Comfort

An incorrectly sized HVAC system can lead to the growth of biological contaminants that may clog your air filters and reduce airflow in your home. This can lead to the spread of allergens that can trigger asthma and allergy attacks. You may also experience symptoms such as nausea, headaches and irritation of the nose and throat.

If you experience reduced comfort and health issues in your home, your HVAC system may be incorrectly sized. You may also experience odors coming out of your system, especially if it’s too big. If your HVAC system doesn’t meet the sizing requirements, you may have to replace it with a new one to improve comfort in your home.
