If your HVAC system is on its last legs, constantly breaks down, and isn’t keeping your home pleasant, it may be time to replace it. The average life expectancy of ducted heating and air conditioning system is roughly fifteen years, according to a report published by the National Association of Home Builders and Bank of America.


Here are some things you should consider when buying a new HVAC system.


1. Get the Correct HVAC System Size


Older houses may not have the proper sizing scheme. We discovered furnaces installed that were more than double the size required for the property. Oversized equipment cycles too frequently, reducing its life and providing less comfort and indoor air quality than a properly sized system. Your contractor should inform you what size system you need for your home and should be willing to perform a “Manual J” load calculation on your home to establish the proper system size.


2. Purchase a High-Efficiency HVAC System


Purchase the most energy-efficient HVAC equipment you can afford that will operate with your home. The labor component of HVAC installation is approximately the same for a standard-efficiency system vs. a high-efficiency system, but the greater efficiency system usually more than pays for itself throughout its lifespan. High-efficiency systems can frequently reduce heating and cooling costs by 30% or more! Remember that you simply need to justify the cost difference between the regular system and the premium, high-efficiency system. Purchasing a high-efficiency system is almost always the best option.


3. Purchase IAQ at the same time you purchase your new system.


Indoor Air Quality components, such as humidifiers and high-efficiency air filtration systems, are frequent HVAC system add-ons. When installing a new system, most contractors will discount these extras. When you’re sitting at the kitchen table with the contractor, inquire about add-ons. During the installation of your new system, you may be able to earn a discount on your IAQ products.
