Regular maintenance is the single most important aspect in extending the life of your heating and cooling system. Some people believe that an occasional filter change is all that is required, and that they will call a service company when something breaks. This is not at all what is recommended. Heating and air conditioning systems contain hundreds of independent parts, all of which can fail without proper upkeep, and only trained technicians can access these parts. Ignoring your system’s needs not only puts you at a significantly higher risk of having a catastrophic breakdown during a hot summer or bitter cold winter, but also considerably reduce the life of your system.
