Welcome to the newest section of the Home Comfort Pages - our Do It Yourself Section. Pages are still being added, so keep checking back. Your home's heating and air conditioning system is a finely tuned assembly of computer chips, timing circuits, motors, starters, temperature- and pressure-sensing circuitry, safety switches and thermal transfer components. Most of these components require specialized test equipment and tools to make adjustments on them.
In spite of the seemingly overwhelming complexity of the system, there are some things that the average homeowner can become familiar with, to maintain some items in the home's heating and air conditioning equipment. Some diagnostic procedures can be performed without the need for special tools and diagnostic equipment. Some of these procedures could even save the homeowner the cost of a service call by a factory-trained technician.
