Compressor failures are one of the most costly repairs to an air conditioning system. It is rare for the compressor to fail simply due to the compressor itself. Usually a compressor failure is symptomatic of another problem with the AC system (more on this in a later Service Matters).
A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the motor. VFDs have been in use since the 1980s, and today, the combination of energy awareness, energy regulations, and new VFD technologies are driving an increasing demand for these energy-saving […]
Some things just naturally go together. Consider: • Peanut butter and jelly • The 4th of July and fireworks • Fred & Ginger • A cold beer at the ballpark Good indoor air quality (IAQ) and effective mechanical system maintenance are two more. Good indoor air quality is complex, and your mechanical system plays a […]
Sometimes it seems that many energy conservation measures related to HVAC systems are incompatible with providing good indoor air quality (IAQ). However, with a little forethought and proper maintenance, significant energy savings from HVAC-system use can be achieved while still providing good IAQ. Follow these simple guidelines and see how you can improve air quality […]
A boiler is a complex piece of equipment. While some diagnostics can be done by observation, a detailed understanding of a boiler’s operation can be diagnosed through a combustion analysis, similar to your family doctor ordering “a complete blood-workup” with your annual physical.
