How do you know when it's time to think about replacing an HVAC unit? Most homeowners don't always know when their heating or cooling system needs attention, but they do know that they don't want to wait until the whole thing breaks down. Here are several of the most important signs that it may be time to replace your HVAC unit.

An Older Unit Starts Showing Trouble

HVAC units tend to last around 10 to 15 years before they start developing issues (and that's with regular maintenance, too). Around this time you may notice loud noises or failed components — broken fan belts, for instance, or furnace ignition issues. These are signs that the unit is reaching the end of its life, and you may want to consider looking at replacement units now rather than waiting for full failure.

You Notice That Heating/Cooling Bills are Growing More Expensive

If you have thought, "My cooling bills seem a lot higher this summer than last year," or something similar to that, it's probably smart to get your HVAC system inspected. Growing expenses mean that your unit has to work harder to perform the same temperature changes in your home. That could be a relatively minor repair, like adding more refrigerant, or it could mean that your system is aging and losing much of its efficiency. Find out the cause and make your plans.

Your Thermostat Changes Don't Do Much Anymore

If you keep adjusting the thermostat but don't feel much of a change, this is a sign that your system may not be able to keep up with your needs any longer. Arrange an inspection to make sure your temperature sensors are working, and see if your system needs to be upgraded (this is more common if you've recently had a significant renovation).

Repairs are More Expensive Than They're Worth

A point comes when the repairs you need to make to HVAC components are no longer worth the cost, compared to the price of buying a new unit. There are several formulas that experts can use to compare repair and replacement costs. Ask our technicians which will be the more cost-effective option in the long term!

You're Still Uncomfortable

Is your HVAC system not meeting your needs? Maybe your home still feels too humid, even if you're controlling the temperature. Maybe you still suffer from allergies even after you replace HVAC filters. These are signs that your system needs an upgrade to match your life. Look into replacements that include the features you need, like extra filtration or dehumidifiers.
