Cooling and heating systems require routine maintenance to maximize performance, maintain efficiency and to insure safety. In the past, systems were simple by design and had less moving parts but they have become more complex due to safety and efficiency standards.
Take the example of automobiles. Cars made in the 60’s were relatively easy to work on, and didn’t take a lot of complex tools and knowledge to fix. In the 70’s due to the gasoline crisis, vehicles were mandated to become more efficient, and they also increased safety standards. Try working on a car today with the complexity of computerized controls and systems.
The same thing has happened to heating and air conditioning systems. The government has mandated that they be more efficient and safer than the units of the past. As of January 2006, air conditioners must be at least 13 SEER rating (seasonal energy efficiency ratio) – which is a lot like miles per gallon. The higher the SEER, the more efficient the system.
Cooling and heating systems are one of the biggest expenses in a home. Maintain your system to assure a long reliable life.
