what is normal life cycle for hvac system?
Most vendors who supply HVAC OEMâs with components, both electronic and mechanical, will tell you they are tasked with providing products with an expected life span under normal usage of 15 years. This is not to say all components and by extension the systems they are installed in will last 15 years, then fail. Many will last longer while some will fail sooner, depending in large part on the list of factors discussed earlier. So the quick answer would be a prudent life cycle planning time is 15 years. Budgeting and planning for replacements after that many years is well worth the effort when compared to the downtime and unhappy occupants in a home or building with no cooling in summer or no heat in winter.
