4 Signs Your HVAC Unit Needs to be Replaced

4 Signs Your HVAC Unit Needs to be Replaced

A traditional HVAC system usually lasts up to 20 years. When you have had a heating and cooling system in your home for that period of time, it begins to show signs of needing to be replaced. Consumer Reports surveyed nearly 30,000 homeowners in 2013, and found that homeowners who did not know what warning signs to look for when an HVAC system needed replacement spent more money repairing them than buying a more cost efficient system. Here are some of the most common signs that tell you that your HVAC system may need replacement:

Irregular Air Temperature

HVAC systems that are experiencing problems with improper air temperature each time they switch on tend to need to be replaced. This means that you are getting tepid air instead of the ice cold conditioning of your home you are expecting in the summer. You could also be experiencing air that is too warm in the winter and is constantly having to adjust your thermostat.

Air Flow Blockage

This is an obvious warning sign when you are in one room that is cold and then you go into another room that is too hot. There may be multiple components in your HVAC system that are malfunctioning. There may be cracks in the ductwork that are allowing air to escape. It could also mean that mice or birds have built nests within the ducts and blocked the air flow and caused irreparable damage to the unit. It will more than likely also show in a much higher utility bill each month.

Unusual Sounds

Most people expect a steady noise from the HVAC system that may sound like a quiet humming along with the sound an HVAC unit makes as it turns on and off. Any other sounds are a sign that something is not working properly. This could be consistent squealing or scraping noises caused by old belts that are not staying in place. A grinding noise is more severe and may mean that some components have loosened and caused damage over a period of time.

Vent Odors

There is always a slight smell of dust that emits from an HVAC system when it is turned on in the winter. Beyond this, any type of odor is a sign of something that needs to be replaced. This could mean a burning smell which is a sign of wire damage. A mustier smell could mean that mold has infiltrated your ducts and they need to be replaced.

According to Consolidated Edison, one of the largest utility companies in the U.S., with an abundance of more cost-efficient systems available today, it makes sense to heed the warning signs of HVAC system issues and consider an HVAC replacement and qualify for an HVAC tax rebate as well.
