How Many Volts Typically Run Through an Air Handler?

AC units need annual maintenance checks in order to properly function. This includes making sure the air handler volts are at the right levels. A technician from Portage, MI will assess the voltage and address problems that are hindering the AC unit’s performance. Here are some factors that determine how many volts run through an air handler.

Capacitor voltage

The capacitor is an essential component for every central AC unit. It generates and stores voltage, powering other components such as the compressor, contactor and air handler. The maximum electrical load of your AC unit’s capacitor determines how many volts run through an air handler.

The average capacitor generates between 220 and 245 volts. However, the air handler voltage will be much smaller. Each terminal on the contactor should only receive between 24 and 28 volts. With that said, just because a capacitor can generate up to 245 volts doesn’t mean it should be sending out that much to the rest of the AC unit. A technician in Portage, MI should run a test to make sure the air handler is receiving proper voltage.

Keep in mind that capacitors have slight differences, and installing the wrong one will compromise your AC unit. Some can generate up to 440 volts, while others have a smaller capacity of 370 volts. If you need to replace the capacitor, check the manufacturer’s guidelines and consult a technician for assistance.

Size of the home

The air handler voltage might be smaller or bigger depending on the size of your house. Generally, larger houses need larger AC units in order to properly cool down all the rooms. Some homeowners in Portage, MI make the mistake of purchasing the biggest AC unit available because they believe bigger is better. However, an AC unit that is disproportionately larger in relation to the dimensions of their house will hike up energy costs and quickly burn out.

When it’s time to replace your AC unit, an HVAC contractor can suggest proper models based on the size of rooms that receive air conditioning. Picking out the right AC unit is less about how many volts run through an air handler and more about making sure it’s appropriate for the size of your home.

Insulation quality

Your AC unit might send higher levels of voltage through the air handler if your home in Portage, MI is constructed with many floor-to-ceiling windows. Outdoor heat gains easy access to your home through windows, especially if they’re poorly insulated. Walls with very little insulation could also be making your air conditioner work overtime. Hire a technician to install a larger AC unit if the current one struggles to maintain cool temperatures.

Air handlers must receive the proper amount of voltage in order to effectively cool down houses during the hot months. Measuring electrical currents is very dangerous and requires the expertise of a trained professional. The technicians at All Brands Heating & Cooling will run a maintenance check and provide AC unit repairs in case we detect a problem. Reach out to us today to schedule an appointment.
