You may have heard that replacing your home’s HVAC system may help to lower energy costs, enhance comfort, and reduce repair costs.

While heating and air conditioning systems range in quality and longevity, a typical HVAC system will last up to 15 years. However, this estimate involves making several assumptions about the quality of care your HVAC system receives, how much use it gets, and how efficient your HVAC system was to begin with. For example, an HVAC system that is meticulously cared for, receives regular professional maintenance, and has its furnace filter and other components replaced regularly may last much longer. Homeowners who don’t even know what a furnace filter is have to consider replacement much sooner.

When deciding whether to replace an HVAC system, you should always consult an HVAC repair professional . Here are some of the factors he or she will consider when evaluating your heating and cooling system:

1.      Energy Efficiency: Given your HVAC system’s SEER rating and AFUE ratio, a professional will be able to determine whether your HVAC system is costing you more than it should.

  2.      Age: If your HVAC system is approaching the end of its projected lifespan, replacement may be the most economical option. If it will continually break down and require repairs, it may actually be less expensive to replace the entire system.

  3.      Overall Performance: Some HVAC systems will become noisy, unresponsive, or simply unusable as time goes on. If you aren’t happy with it, then replacement may be a better option.
