HOW DO I PICK THE CORRECT VOLTAGE CONTACTOR FOR MY HVAC CONDENSER?
HVAC systems require different types of contactors and choosing the right one could be a crucial task. A contactor’s job is to control the flow of electrical power to HVAC equipment, and the correct contactor must be properly selected to avoid malfunctioning of the HVAC system.
There are two primary specifications to focus on when selecting the right contactor – voltage and amperage. Voltage represents electrical potential and is measured in volts, and amperage represents electrical current and is measured in amps.
Before selecting the correct voltage contactor for your HVAC condenser, it’s essential to check the old contactor to find out its specifications. If you are replacing your old contactor with a new one, it’s best to look for a replacement with the same specifications as the old one. The voltage and the number of poles required for the contactor are some of the critical factors to look for when selecting the correct one.
Next, you can determine the voltage and amperage ratings from the electrical panel on your AC unit. The panel has labels that contain information on the minimum and maximum voltage and amperage ratings that your contactor should possess. You should select the contactor with the same specifications as per the electrical panel.
It’s also essential to consult the manufacturer’s manual, which contains detailed information about the appropriate contactor type suitable for your specific HVAC unit. This information includes the voltage specification, current rating, and the recommended manufacturers to purchase from.
In summary, selecting the wrong voltage contactor for your HVAC equipment will impact the overall performance of the equipment and may cause it to malfunction. It’s crucial to consider all the specifications mentioned above to ensure you choose the correct contactor that meets your system’s needs.

HOW TO PICK THE RIGHT CAPACITOR FOR YOUR MOTOR?
- LOOK AT THE MOTOR TAG/NOMENCLATURE
This can be found on the motor itself or the motor box.
- READ THE CAP SIZE
Each motor and motor box lists the proper cap size the motor needs to run.
- DETERMINE IF YOU WILL USE A DUAL OR SINGLE RUN CAP
Depending on the motor function (blower VS. condenser), and the wiring of your condenser, you can select a single motor run capacitor or a dual motor run capacitor.
