When is it time to replace your HVAC system?

It’s always a tough decision to replace your HVAC system. After all, it’s an enormous investment, and you don’t want to do it too soon. But if you wait too long, the consequences can be costly. In this blog post, we’ll discuss 10 warning signs that show it might be time for a HVAC system replacement. So don’t wait – read on to learn more!

  • Your HVAC system is over 10 years old.


    Depending on numerous conditions, the typical lifespan of an HVAC unit is between 10 and 20 years. Systems begin to deteriorate as they age. The more often an HVAC system is used, the faster it ages. After a certain point, replacement becomes the more cost-effective choice due to significant savings on repairs, maintenance, and energy expenses.

  • If you’ve had to repair your HVAC system multiple times in the past few years.

    If you’re frequently spending money on high-priced heater or air conditioner maintenance (or your AC isn’t performing as effectively as it should), it’s in your best interest—and the best interest of your bank account—to invest those dollars in a replacement instead.

  • You can’t keep your home at a comfortable temperature.

    This includes having difficulty cooling and heating your house in the summer and winter. It may not be able to eliminate humidity as efficiently as it usually did, making your home atmosphere less pleasant.

    When an HVAC system becomes old or in disrepair, it no longer functions as effectively as it once did. When a unit is inefficient, it cannot perform the function for which it was built. When your home’s temperature can no longer be maintained, you should consider replacing your HVAC equipment.

  • Your HVAC system is costing more to operate than it did before.

    Regular maintenance, particularly changing air filters on a monthly basis, will extend the life of your HVAC system and keep it functioning as effectively as possible… However, you will need to switch to a newer system at some time. The good news is that replacing your air conditioner can reduce your total energy expenses by up to 20%. Many customers discover that their new air conditioner has paid for itself in a surprisingly short amount of time!

  • If you notice unusual smells and odd sounds.

    If you detect a strange odor coming from your HVAC system, it might be dust burning off, but it could also be something far more dangerous, such as melting wiring or mold in the ducts. If the odor is more serious, switch off your system immediately and get it examined.

    A well functioning HVAC system should be relatively quiet. If you hear grinding or screeching noises, this is also a warning that your system needs to be inspected right away.

  • If you have poor Indoor Air Quality.

    If you discover mold, mildew, dust, or odd humidity levels, your air conditioning equipment may be damaged and should be replaced. Remember that an NIOSH (National Institute for Occupational Safety and Health) research study indicated that poor ventilation was responsible for nearly fifty percent (52%) of Sick Building Syndrome instances!

  •  Your HVAC system has an air conditioner that uses Freon (R-22).

    While you may continue to use your air conditioner, R-22 is being phased out in the United States due to environmental concerns. So, if adding more R-22 coolant is the solution your air conditioning unit requires, you may need to make the decision to replace your old unit. So, while you might be able to get R-22 on occasion if that’s the patch your AC requires, it’s going to become increasingly expensive and difficult to come by. The growing expense of the refrigerant will quickly justify the purchase of a new system.
