HVAC systems are an integral part of any modern home or business. Knowing how they work and the various components is important to ensure that your building is comfortable and efficient all year round. Here are some interesting facts about HVAC systems you may not have known.

1. They Need to Be Maintained Yearly

The most important thing you need to know about your HVAC system is that it needs to be maintained annually. Doing so will ensure maximum efficiency and performance, as well as prevent any repair costs in the future. This means having a professional technician come out to inspect, calibrate, and clean all parts of the system at least once a year. Unfortunately, many homeowners don't bother to check their system until the thermostat isn't working. By having yearly maintenance performed, you can ensure that it continues to work for years.

2. HVAC Systems Have an EER Rating

An energy efficiency rating (EER) is a measure of how efficiently your HVAC system uses electricity. The higher the number, the more efficient it is. Generally, a good EER rating is at least 12 or more. This number can be improved by adding insulation, sealing ducts, and replacing old parts with energy-efficient ones.

3. They Can Help Reduce Allergens

An efficient HVAC system can help reduce the number of allergens in your home. However, the higher the humidity levels, the harder it is to get rid of moisture and allergens. According to the United States Consumer Product Safety Commission, your home should have a relative humidity of 30% to 50% for better air quality. If you notice your HVAC system's humidity levels are above this range, you should call a technician to inspect and repair the system.

4. Most Systems Last 10 to 15 Years

Based on our team's experience, the average lifespan of an HVAC system is 10 to 15 years. Of course, this depends on how frequently it's used and how well it's maintained. If you notice that your system isn't performing as effectively as it used to, or if it's making noises, these may be signs of a worn-out unit. If so, you should contact an HVAC professional right away in order to ensure the best performance.

Knowing these things about HVAC systems can help you make the most of your unit. It's important to remember that regular maintenance is key and a professional should always be consulted for any repairs or replacements.
