Furnaces, ducts and air conditioners are big investments for any homeowner. How do you know when it’s time for a replacement or upgrade?

Your Energy Bills Are High

This is a telltale sign that your heating and cooling systems are working inefficiently or past their capacity. If you’ve noticed that your electricity bills are consistently rising despite normal use or that they’re abnormally high, it’s time to get your systems checked.

Your Heating and Cooling Units Are Old

If your AC unit is more than 10 years old, or your furnace is more than 15, it might be time to replace it. According to Energy Star, a new furnace can save you up to 15% on your bill and a new air conditioning unit can save you up to 20%.

Hot and Cold Air Are Unevenly Distributed Throughout the House

If you part of your house is toasty warm in the winter and another part is cold, this could be a symptom of bad ductwork or a malfunctioning system. While it's a common HVAC problem, poor insulation can also be the culprit.

Your Home Is Especially Humid or Dusty

Excess humidity or dryness could indicate an equipment malfunction in either your heating or cooling system. Excess dust could be coming in from the attic, which usually signals that your ducts need to be resealed.


Your AC Is Blowing Warm Air

If you turn on the air conditioning, but your HVAC only blows warm air, then you could have several issues. In older units, this issue likely has to do with a lack of coolant or Freon. Freon-based HVACS have been phased out and the coolant is more expensive every year. Eventually, it will become more cost-efficient to replace your old HVAC unit with a modern one.

Your HVAC System Is Noisy

Hearing lots of noise when the air kicks on is an indication that your furnace or AC unit is overworked. If there are lots of clunks, bumps, and shudder noises coming through your vents, it may be time to upgrade to a more powerful and efficient system.

If you’re experiencing any of these issues, it’s time to talk with a certified HVAC contractor about your options. Depending on the weather where you live and how often you use your systems, it may be much more cost effective to do a small repair than to replace your whole system. But, if it’s a larger, more costly repair, it’s possible you could make your money back in energy bill savings if you invest in new heating and cooling units.

Find an HVAC professional near you and ask them about your potential for money and energy savings with a replacement versus a repair!
