When Should I Replace My HVAC System?

Replace My HVAC

When you’re living on a budget, you try to get the most out of everything. Maybe you should replace that old car, but you’ll drive it around Birmingham, Alabama, until it breaks down. Maybe it’s time for a new wardrobe, but that shirt that’s fit since the ’80s still works, so why ditch it?

While stretching out the use of expensive items in your life won’t do any harm, the same can’t be said for your HVAC system. If you wait until your system fails, who knows how long you’ll have to deal with reduced comfort and indoor air quality. To avoid the consequences of a dead HVAC system, know ahead of time when you should replace your unit.


Even technology isn’t free from the damage of time. No HVAC system will last forever, and many only last between 10 and 15 years. If you’re coming up on that time, pay attention to other symptoms of potential failure.


As systems age and experience compounding strain, their efficiency will drop. You may notice your utility costs climbing or that your home isn’t as warm as it should be, despite the thermostat being set the same. If you recognize a trend of falling efficiency, schedule a maintenance appointment. Your HVAC technician will be able to further diagnose the issue and determine if you need to replace your system.

Indoor Air Quality

Falling indoor air quality is another indicator that you should consider replacing your HVAC system. If you’re noticing more dust in your home than normal, you’ve been changing air filters regularly, or if you can’t seem to get rid of your sudden onset of allergies, have a technician look at your system. You could have a problem with airflow, filtration, or something else that could point toward the necessity of replacement.

We know that replacing an HVAC system is often intimidating, but by looking ahead to replacement, you can plan rather than be taken by surprise. To upgrade your HVAC system, call Total Comfort Heating and Air at (205) 386-2056.
