Why spend money on HVAC maintenance? This is a common question many consumers ask. It is understandable to not want to spend money on preventative maintenance and pay only when there is an actual problem. However, a little money spent to improve the reliability of your HVAC system, may save you from being presented with a large bill due to a problem that could have been avoided with a little care. Having a technician come and inspect your unit at the house, or the office at least once a year will reduce the chance of having a serious issue appear. The goal is to catch problems when they are s mall and not catastrophic. Following a couple of basic tips such as clearing vents, changing filters, moving debris from outside units and cleaning coils and parts can add years to the life of your HVAC system. Ask the technician for some pointers pertaining to your particular unit model and he/she will undoubtedly provide advice that will increase the reliability and longevity of your HVAC system. Ask the technician what it would cost to replace your unit, or some of the big parts that operate within it. The cost may surprise you and motivate you to pay the lesser price of a yearly inspection, instead of a full replacement. It is surprising how much longer HVAC systems would last if owners were pro-active in their care, similar to the way most car owners change their oil, or get tires rotated. The key to reliability and longevity is through proper maintenance. Keeping your system running to the best of its ability can lower your power bills, and allow your system to cool and heat with increased efficiency. It will be able to perform its function successfully and hopefully for a long time.
