INDIANAPOLIS — In my last Home Zone, I showed you how to change out a capacitor in your air conditioner. That $15 part and 15 minutes of work saved me about $300 off an estimated repair bill ...

Key Takeaways Replacing a condenser fan motor for an AC unit costs $450 on average, but could be much lower if it’s under warranty. Other costs to consider include HVAC labor costs and total AC ...

An AC unit has two capacitors: a run capacitor and a start capacitor. A start capacitor provides the first push to spin the condenser fan.

Capacitor replacement is probably the number one service call for HVAC technicians. When your thermostat calls for AC or heat, the capacitor provides the initial 240 volts to start the compressor ...

Capacitors are another weak link. These store and release electricity to get the motors running. When a capacitor fails, the fan or compressor won't start at all, or may shut off mid-cycle.

A popular style of fan motor used on older refrigeration equipment is the permanent split capacitor (PSC) motor. It is an electric motor made up of essentially two magnets: one is stationary (the ...

But if the fan still makes lots of noise at higher speeds and only a small, slow volume of cold air is coming through the vents, there’s a good chance that the fan’s motor is fine, and it may ...
