Heating and A/C Replacement Systems

You may be noticing some strange noises coming from your heating or air conditioner as you crank it on for the first time in the season. For many, this simply means that a tune-up or minor repair is necessary, but for some the groans and grinds coming from your unit mean that it is time for a heating or air conditioner system replacement.

Many older HVAC (heating & air conditioning) systems are only made to last about 10 years before they need to be replaced, and while a full air conditioner replacement can be expensive, most units are designed to wear out and a full system replacement is necessary eventually. Thankfully, in recent years HVAC technology has come a long way. New units last longer than their older counterparts and are more energy efficient, saving you money on your energy bill each month.

Some common signs that it may be time for an heating & air conditioner replacement are:

  • Your HVAC system is more than 10 years old
  • Your energy bills start going up
  • Your system requires frequent repairs
  • Some rooms in your home are too hot or too cold no matter how you set your thermostat
  • Your system becomes noisy
  • A home energy audit shows that your dated system is using excess energy
