4 Obvious Signs It’s Time to Replace Your HVAC System

We know that shopping for a new HVAC system can be quite a chore. However, there will come a time where this will be inevitable. And while you may want to put this off, it’s best to do it as soon as possible to avoid any issues down the line. Now, it can be rather tricky to determine when an HVAC system needs to be replaced. This is why we thought it would be useful to put together a brief article about obvious indicators that you may need a new HVAC system. Here are some tell-tale signs that it might be time to start shopping for a new HVAC system.

Your AC System Is Old

Homeowners should replace their HVAC system every 10 to 15 years, according to the Department of Energy, in order to reduce their carbon footprint and monthly energy bills. AC units that are more than 10 years old use a refrigerant called R-22, which is outdated and harmful to the environment.

Your Energy Bills Are Unusually High

Your energy costs may vary seasonally, but if you notice a sharp increase from one month to the next, it could be a sign that your HVAC system needs to be replaced or serviced. As systems age, their efficiency declines, so regular maintenance is important to extend the life of your AC unit and keep it running efficiently. However, eventually, you will need to upgrade to a more efficient model, which could save you up to 20% on your energy bills.

You Can’t Keep Your Home at a Comfortable Temperature

If your HVAC system is having trouble maintaining a consistent temperature in your home, it could be due to a number of factors, such as a damaged or inaccurate thermostat, low fluid levels, clogged filters, cracked ducts, or serious damage to the motors. Continuing to use your AC system without addressing the issue will result in an uncomfortable home environment and increased energy bills. It is important to note that all homes are different and will therefore have different heating and cooling needs. When choosing a new AC system for your home, be sure to take these factors into consideration.

Your Home Has Gotten Dustier

Your HVAC system is responsible for providing both cooled and heated air throughout your home, as well as maintaining proper ventilation. If your system is working efficiently, it will improve the quality of the air inside your home by removing dust and debris and keeping humidity under control. If you have noticed more dust than usual, it could be a sign that your system is no longer efficient and needs to be replaced.


We hope this article helps you figure out when you need to buy a new HVAC system. While it may seem tricky at first, it can be rather easy as long as you know what to look for. Be sure to keep everything we’ve discussed here in mind so that you can make the most informed decisions regarding your HVAC systems.
