Like any major HVAC systems require preventative maintenance. To stay in good working order. Units require different kinds of maintenance. Based on where they are located:
Inside or outside.
With outdoor units, it is important to check certain components. Such as the compressor and its tubing, the control box and wires. Accessories, connections, fan motor and blades. To determine if there is any wear and tear.
It is also important to examine the coil and cabinet. And clean these components when necessary. Being sure to remove any dirt, leaves, or other unwanted debris. It’s essential to verify the unit. That has the proper refrigerant level. And to make any necessary adjustments. Be sure to check the base pan and clear any obstructed drain openings.
Indoor units require additional maintenance. Including checking the ductwork for leaks, cleaning the combustion. Blower housing, replacing or cleaning air filters. And checking the flue system. It is important to turn the system on. And check for any unusual noise or odors. As well as monitor the system’s operation. While the system is running, it is necessary to measure other features.
Including the dry and wet bulb temperatures. The high and low side pressures, and the temperature rise. It is a good idea to have a professional perform this routine. We recommend HVAC maintenance two times per year.
