There are so many parts and components that comprise an HVAC system. Some of these parts and components are not instantly striking in terms of appearance — a few examples include insulation foams, fan guards, and copper components. But at the same time, there are other components that immediately catch your eyes, such as filter driers, condensers, and evaporators. Another perfect example of a conspicuous HVAC component is the capacitor.

What Is A Capacitor?

Simply put, a capacitor is a device that stores electrical energy in an electrical field. It is previously known as a condenser or condensator, and it is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance. Whereas some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component that is designed to add capacitance to a circuit.

Practical capacitors vary widely in terms of physical form and construction. That said, most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces that are separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. Meanwhile, the non-conducting dielectric acts to increase the capacitor’s charge capacity, and materials commonly used as dielectrics include glass, ceramic, plastic film, paper, and oxide layers. Long story short, capacitors are extensively used as parts of electrical circuits in many common electrical devices, such as HVAC systems.

For that reason, it is not surprising that capacitors are required for HVAC systems. And so, as an HVAC professional, it is your responsibility to make sure that the HVAC systems you’re offering to your customers are equipped with high-quality capacitors. In order for you to be able to fulfill this responsibility, you must first need a reliable manufacturer or wholesale supplier of capacitors to work with you.

Luckily, there are a lot of these manufacturers and wholesale suppliers out there. In particular, you can find a number of them in Canada alone. And so, if your HVAC business is based in Canada and you’re looking for a manufacturer or wholesale supplier of capacitors, here are ten companies that you can start looking up.
