Over our many years of experience, we’ve received countless questions about heating and cooling systems and services. We’ll answer some of the most common questions to help you stay informed on the subject.


The replacement timeline for your HVAC system depends on the type of equipment you have. Furnaces last between 15 and 30 years with proper care and maintenance, depending on the type. Central air conditioning systems can last up to 20 years. Heat pumps typically last 10 to 15 years, and ductless mini-split systems usually last 15 to 20 years.

Anytime your heating system behaves abnormally, it requires a professional evaluation by qualified technicians. Signs can include unusual noises, strange smells, short cycling, inconsistent heating, or an appliance that won’t turn on. You may also notice decreased heating performance or higher energy bills than normal.
