On average, an HVAC unit lasts between 10 and 20 years. Considering this great variance in lifespans, owner’s should note replacement warning signs. These may become more apparent after 10 years of use. Symptoms of an HVAC in need of replacement include higher energy bills, unusual smells and sounds, and slightly too hot or cold temperatures. Since some symptoms may be vague, it’s a good idea to look to the professionals for an accurate diagnosis.
