When your HVAC system is old and no longer works properly, it can mean a much less comfortable home, higher electric bills, and poor indoor air quality. While many HVAC issues can successfully be repaired, eventually your HVAC system will simply exceed its lifespan and need to be replaced. Here are five signs it's time to replace your HVAC system:
Lots of Dust
Your furnace or air conditioner filters should be changed monthly during the time of year they're in use. This keeps your air clean and fresh. If you have been consistently changing your filters and notice an excessive amount of dust showing up on your floors and furniture, this can be a sign that your HVAC system is no longer able to properly circulate air and ventilate your home.
Did your home used to be consistently warm or cool but you now have pockets or entire rooms that never warm up or cool down? This is a common problem with failing HVAC systems. A new HVAC system will keep your home evenly cooled and heated, without any one room being less comfortable than the rest of your home.
If your HVAC system has issues once in awhile but generally works great, it can make sense to get it repaired instead of replacing the entire system. If those repairs become a frequent occurrence, however, it's a sign that your system is breaking down and failing. Your new HVAC system will work efficiently with only very rare issues.
Sometimes homeowners gradually get used to loud clanging sounds when they turn on their HVAC system, but unusual or loud noises are a pretty bad sign. A new, efficient HVAC system will be so quiet you barely notice it running in the background.
Higher Electricity Bills
Perhaps the most important sign that your HVAC system should be replaced soon is that your electricity bills get higher each month, even though you're not keeping your home any warmer or cooler than usual. As your HVAC system wears down, it has to work harder and harder to maintain even a basic level of comfort in your home, and that means higher energy bills.
If you notice any of these signs, it's a good idea to have your system inspected by a professional HVAC company such as Metro Air. They will help you determine for certain if it's time to replace your system, and help choose the best system for your heating and cooling needs.
