As 2015 gets underway, you may find yourself scanning your home for things that need to be repaired or replaced entirely. Should you add your HVAC system on that list? Maybe. It’s easy to tell when an upgrade is due when there is a major problem, but your HVAC system may have been dropping subtle hints that went undetected for a while.
Your HVAC system should heat and cool your home consistently. Inconsistent temperatures and excessive dust and humidity should raise some concern. These are typically signs that your ductwork needs to be sealed or has failed. Excessive noise is also indicative of a problem. Properly working systems are fairly quiet, so a noisy system could be a sign that there’s a problem with the indoor coil. Your system may also be undersized for your home.
Unless you took steps to lower your energy costs, your utility bills shouldn’t vary too much from year to year. Large increases on your statement could be a painful indicator that your system isn’t working as efficiently as it used to.
Older models are also less efficient than new ones. Your system’s lifespan is likely about 10 to 15 years, depending on how well it was maintained. New Energy Star systems can help save up to 20 percent on heating and cooling costs, compared to older models.
