Common HVAC Misdiagnoses
As an HVAC and controls service specialist, much of MSC’s business comes from clients who are frustrated with other contractors’ costly misdiagnoses. Most are due to technicians who lack proper training and rely heavily on guesswork, or HVAC contractors who make their living replacing expensive parts and equipment rather than diagnosing and fixing the actual issues at hand.
The most commonly misdiagnosed HVAC problem, and one of the most costly, is compressor failure. It is extremely important to identify why a compressor failed and correct the underlying problem so the new compressor doesn’t fall victim to the same issues. The same goes with premature motor failure. Dirt, improper ventilation, motor overload, voltage irregularities, etc., can cause a host of issues. If cause for failure isn’t addressed, the new motor will almost certainly fail as well.
Many HVAC service techs are perplexed by electrical and control issues and CPU faults, and often apply the wrong fix. “It could be the board” is a vague and insufficient diagnosis. Problems with airflow and water circulation can also go unrecognized. Improper flow or velocity can cause heat exchange problems, and many HVAC technicians don’t have the proper knowledge to identify these issues. Finally, recharging low refrigerant is a temporary patch, not a fix. If there is a leak, the source should be identified and remedied to prevent serious damage.
