Many customers ask, each time a repair is need for their heating and air conditioning system comes up, the following question: "Should I replace my central air system or repair it?" For the homeowner, that is a tough question to answer. The picture above shows you a rule-of-thumb way to determine when it makes sense to repair or replace.
The rule-of-thumb for determining whether to replace a home heating & cooling system is simple: older systems with higher and more frequent repair costs need to be replaced. A newer system, including those just out of factory warranty or about to come out of an extended warranty, should be repaired. 15 years is the normal "wear" life of a home HVAC system. If your furnace and air conditioning system is 20 years old or older, then you should replace it. In the long run you will save money through lower operating costs.
