Common questions

What is the 3-minute rule for AC?

The '3-minute rule' for AC systems is a guideline recommending a minimum run time for the compressor to prevent short-cycling. This operational pattern can lead to premature wear on crucial components such as the start capacitor and motor. Proper system charge and unobstructed airflow are vital for maintaining this operational parameter.

How much does an average HVAC job cost?

The cost of an average HVAC job in Wisconsin is highly variable, depending on the specific repair required, the complexity of the diagnosis, and the labor rates in the service area. Routine repairs, such as replacing a thermocouple or cleaning burners, are generally less expensive than addressing issues with the heat exchanger or the main gas valve.

What is the most common HVAC repair?

The most frequently encountered HVAC repairs often involve ignition system failures, such as a malfunctioning ignitor or a dirty flame sensor, and issues with gas flow or control valves. These components are critical for the safe and efficient operation of gas furnaces throughout Wisconsin's cold winters.

Can I fix my HVAC myself?
How do Wisconsin's codes affect gas furnace repair?
