When should you replace your HVAC unit?

Understanding when to replace your HVAC unit

As temperatures continue to rise in Tennessee, you may notice your HVAC unit working extra hard to keep up.

While there are many things you can do to make sure everything is working as efficiently as possible the cold truth may be that it’s time to repair or replace your HVAC unit.

If you’ve replaced the air filter, cleaned the unit and cleared away any debris, unclogged the pipe near the unit and made sure the thermostat is working accurately, you’ve done most of what we recommend. The following are signs that it may be time to call a professional.

Getting old

When did you buy your HVAC unit? The average unit can last 15 to 20 years. But depending on how much it’s been used and how well it’s been taken care of, you may need a new one sooner. Getting regular maintenance and frequently changing the filter can extend the life of your unit. But if it’s older than 10 years and isn’t working as well as it once did, it’s time for us to come have a look.

Sounds and smells

Obviously, you can hear your HVAC unit when it kicks on and while it’s pumping air into your home. But that should be a relatively quiet sound. If you’re hearing clangs and bangs, something is wrong. This could mean you need a part – or the entire unit – replaced.

If a musty smell accompanies your HVAC unit turning on, this could be a sign that there is mildew or mold that needs to be addressed. If you smell gas, it could be even more serious. We recommend you leaving the house and calling us immediately.

Low SEER rating

Your unit’s Seasonal Energy Efficiency Ratio rating measures the ratio of cooling output over a season divided by the energy it consumed. Essentially, it lets you know how efficient your unit is going to be, and therefore how much it cost you to operate it.

Most air conditioners these days have a SEER rating between 14 (good) to 25 (great). The higher the number, the more you’re likely to spend on the front in and save in the long run. As standards improve, newer units are most often going to be more efficient than older ones. If your unit has a low SEER rating, it may be time to upgrade.

Too small

When most people buy their homes, they don’t immediately update the HVAC unit. But over time, they can realize that the unit in their home doesn’t suit them. Some people just like to be cooler in the summer and warmer in the winter. If you’re one of these people and your HVAC unit can’t keep up, you should consider getting a bigger one.

Costly repairs
