A “perfect ten” isn’t so perfect when you’re talking about your home HVAC (Heating, Ventilation, and Air Conditioning) system. If your system is 10 years old or more, it’s time to start considering a plan to replace it.

Why? There are several reasons. Older systems are outdated in terms of their energy efficiency. They rely on environmentally detrimental refrigerant. When (not if) your system is in need of repairs, you also run the real risk of no longer being able to find affordable replacement parts.

Let’s take a closer look.


Noise coming from the outdoor or indoor unit is more than unpleasant. It’s not a good sign. It likely means that one of your system’s major components has failed. If your system is making unfamiliar noises, it’s time to contact your HVAC professional for consultation.

Increase in Energy Bills

Your heating and air conditioning system is responsible for a large portion of your energy bill. If the amount due on your most recent energy bill is much higher than you expected, your HVAC unit could be to blame.

Home is Uncomfortable

Your HVAC system’s primary job is to keep your home as comfortable as possible. When it’s working properly, your system should be delivering crisp, comfortable air to all areas in your home. If you notice your home is too hot, too cold, or too humid, this is a sign your HVAC system is inefficient or beginning to fail.

Odd Smells

Your air conditioner should never emit any questionable odors. If your the output of your A/C or heater smells moldy, musty, or like it’s burning, call your HVAC professional immediately to investigate the problem. While there are a wide range of issues that might cause your system to emit bad odors, many times this is a sign that your system will need to be replaced soon.

Indoor Air Quality

Air inside your home should be well filtered. If you begin to see more accumulation of dust or debris in and around the ducts, on surfaces, and in the air, this is likely a sign your system is older and unable to keep up with demands.

SEER Rating

Currently, the minimum required SEER (Seasonal Energy Efficiency Ratio) rating for new equipment is 14. Particularly if your HVAC unit has less than a 13 SEER rating. you’re losing out on the many benefits of newer, more efficient equipment.

Major Component Failure

With older systems, major component failure can be extremely expensive to repair. If your older HVAC equipment is broken and facing thousands of dollars in repair costs, consider upgrading a new system rather than repairing it.
