Businesses and facility managers often encounter inefficiencies in their heating, ventilation, and air conditioning (HVAC) systems despite their complexity. The COVID-19 pandemic has highlighted the need for better indoor air quality (IAQ), but many HVAC systems lack adequate ventilation and high-quality air filtration.

Upgrading HVAC systems is critical for various reasons, but the most crucial one is the safety and well-being of building occupants. Therefore, TC'S team of indoor air quality experts has developed a guide for facility managers on upgrading their HVAC systems to improve IAQ.

If your current system is 10 to 15 years or older it may be good to evaluate your system. Technology has changed in the last 15 to 20 years and the new HVAC systems are more efficient. The savings of upgrading to a newer, more efficient HVAC system could be a good investment, especially if your system is starting to show signs of problems. Another time to consider an HVAC upgrade is if you have done major remodeling in your home. Major changes diminish the efficiency of your system and will lead to higher bills and more wear on your HVAC.
While there are a few ways to calculate the correct size of an HVAC system for your home, the most reliable is something called a Manual J calculation. Developed by engineers, Manual J takes into consideration a whole list of factors that include dimensions, insulation, windows, home shape, orientation, and load calculation. Just replacing your HVAC system with the same size isn’t the best option. Changes in your home through remodeling can make a significant difference in how your HVAC system performs. Having an HVAC professional ensures that you have a “just right” system that will save you money and system issues while providing optimal comfort.

The long-term benefits of replacing an aging or poorly performing HVAC system can be significant. Studies have found that high-efficiency systems can lower energy costs by 20% or more. Over the lifetime of the HVAC system that savings add up.

Newer HVAC systems have precision variable speed motors that ensure optimal airflow throughout your home year-round. They are also quieter, minimizing noise throughout your home. Smart thermostats give you the ability to control your entire HVAC system both at home and on your smartphone when you are away.

If you have an older HVAC system that is constantly needing repairs, the cost of replacement will be worth it long-term.
