This could be due to a clogged air filter, a failing blower motor, or even issues within your ductwork. Restricted airflow not only affects your comfort\u2014it also forces your system to work harder, increasing wear and tear and driving up energy costs.

This might be due to a refrigerant leak, a malfunctioning compressor, or a problem with the thermostat. Some of these issues can escalate quickly. Running your system under these conditions could cause serious damage, so it\u2019s best to shut it down and call for service right away.
