According to the Centers for Disease Control and Prevention, hypothermia deaths in the U.S. have increased by around 35 percent since 2014. More than 2,500 people died from the cold last year, mostly in severe winter storms.
Having reliable HVAC is not only a matter of comfort and convenience but one of safety as well. Installing HVAC systems is complex and requires specific electrical supports.
This article covers the basic electrical considerations for HVAC system design and configuration. Keep reading to find out how to ensure safe and effective power is delivered to your system.
Circuit Breaker Capacity
A circuit breaker is one of the central electrical components of your HVAC system. Property sizing is a crucial factor. The electrical panel must have adequate capacity, or amperage, to handle the startup surge that the HVAC system requires.
This depends on their size, but most central air conditioners and heat pumps will need between 15 and 50 amps for startup. The system will require a much lower running wattage but a consistent power source to operate.
Your HVAC system should also have a dedicated circuit, which will prevent overloading the other circuits. An electrician also might recommend upgrading the electrical panel with larger breakers or new circuits, depending on their current condition.
Voltage Requirements
Amperage is the amount of electricity flowing through a circuit. Voltage is the amount of force necessary to send electricity through the system. A home’s HVAC electrical system must be able to provide the right amount of voltage so that it can start up and operate properly.
Otherwise, it will “trip” the circuit and cut power. It also is important to HVAC efficiency.
Most residential ones require 240 volts. Proper grounding also is essential, as it gives electricity a place to flow in the event of a short circuit, which helps avoid shock hazards.
Wiring Requirements
When installing HVAC systems, a stable network of wires is needed to ensure power is delivered to different parts of your system. This includes the main AC or heat pump units, as well as the thermostat.
You need the correct gauge (thickness) of wiring to handle the amperage required to run the system. The installer also must secure any exposed wiring before finishing the project.
There are other wiring considerations. One is that larger HVAC units, such as central air conditioners and heat pumps, require special plugs.
A mismatched plug can cause electrical problems, including tripped or blown fuses. Getting the right one to handle the amperage and voltage the unit requires is vital.
