Your HVAC technician may perform a complete system check. This can include looking over all parts of a system, cleaning it, and performing the routine maintenance specific to your system. Depending on the equipment being evaluated, a routine HVAC maintenance service call may include the following:
Inspecting main HVAC components
Checking for adequate air flow
Inspection of refrigerant lines
Clearing drain lines and pans
Inspecting exterior fan
Tightening electrical connections
Inspecting system controls
Inspecting and lubricating moving parts
Replacing parts that are showing wear and tear
Replacing air filters
Checking electrical connections
If the technician discovers that your ductwork is leaking, they may recommend duct sealing. The U.S. Department of Energy (DOE) estimates that a typical U.S. home loses 20%-30% of duct system air due to leaks, holes, and poorly connected ducts.” A license professional technician can seal your ductwork. According to the DOE, sealing HVAC air ducts can drastically reduce duct leakage and improve both IAQ and overall system efficiency.
Making sure your HVAC equipment is routinely serviced by a professional HVAC technician is as important as taking your car to a mechanic for its required oil changes and maintenance. If an extended service contract or agreement is not already in place, technicians may often offer to set up a maintenance agreement wherein the customer agrees to pay a set fee for standardized scheduled system maintenance. Routine maintenance may extend the life of your HVAC equipment and possibly prevent minor issues from turning into expensive major problems over time.
