This Breaker Controls HVAC! (Must Know It)

Considering the function of a circuit breaker, you must know that the breaker controls the HVAC.

But it gets tricky when you don’t know which breaker it is, particularly that one in charge of the HVAC. Today I’m going to show you which is which.

The breaker that controls your HVAC is located in the A/C electrical switch. There are two breakers or wires associated with the forced air system. One is for the heater or indoor unit. Except if the indoor unit is electric, it will have a solitary breaker. It might very well be a checked heater, assuming you are fortunate. 

How Do I Know Which Breaker Controls My HVAC AC Unit?

Which Breaker Controls HVAC

Locate the A/C electrical switch on your electrical switchboard; it’s the primary power dissemination board that can be situated inside or outside your home.

It’s typically set apart as “A/C,” “Air conditioning,” or “forced air system.” When you find this breaker, switch it off, and afterward, stand by for a couple of moments before turning it on again.

Remember that circuit breakers can seem as though they’re ON in any event when they are stumbled – so try to switch it off and afterward back on once more. 

Likewise, possibly reset an electrical switch once – on the off chance that it continues to trip off, you risk lighting an electrical fire assuming that you continue to walk out on it.

If it continues to trip, it implies an issue, and your smartest choice is to call an HVAC professional. Breakers are circuit assurance that is resettable. 

They appear as though switches yet will break the circuit on the off chance that the amperage through the circuit is higher than the number imprinted on the handle. 

You should track down the legitimate breaker. It could be a heater, assuming you are fortunate.

It will move to the middle when it has stumbled from over amperage in many breakers. To reset, it should be switched as far as possible off and then turned on. 

A few breakers have a window that shows red if it is stumbled. When resetting, if the breaker promptly pops to the middle once more, the circuit has a huge overdraw, and the short should be found. 

Assuming that it stays on, verify whether the unit comes on. If the unit comes on, you are not wrapped up. The breaker might trip following a couple of moments.

The open-air unit will have a twofold breaker since there are 2 shafts for 240 volts.

Which Breaker Controls My HVAC Furnace?

A furnace will have an assigned circuit breaker inside your house’s panel box.

Usually, a furnace has a two-pole breaker due to its massive loads of electricity, which generally fall within 60 amps to 80 amps.

Thus, if you own a furnace but detect a two-pole breaker in your house’s panel, that may be the reason. To verify this, you must check the device to observe if it does service the furnace.

Therefore, there are two means to achieve this:

  • Utilize a finder for your circuit breaker.
  • Turn off the circuit breaker and check if it reduces the power supply to the furnace.

The circuit breaker finder lets you track the exact breaker attached to your furnace.

However, if the furnace does not arrive with a sole outlet enabling you to attach your circuit breaker finder, do well to attach the device’s alligator clips on naked wires to track it.

Randomly turning your breakers off to check which one takes power off to the furnace can help, too.

Nonetheless, I don’t advise that because it can harm the fuse box attached to the furnace because of the abrupt loss of electricity.

How to Reset an AC Circuit Breaker?

For you to go about this process, you need to have;

  • Gloves and 
  • Replacement Circuit Breaker

After which, you can further with these steps below mentioned.

#1. Step 1: Find the Service Panel

Before inquiring about the location of your  AC breaker, you’ll, for the most part, find the basic help board on the opposite end of the device’s electrical meter.

The electrical help board is situated in the storm cellar or carport. Be that as it may, you could have to inquire as to whether you’re living in a condo.

Then, keep in mind that the area of the AC breaker frequently changes per foundation. You might have to counsel your property’s electrical chart if you can’t find it.

#2. Step 2: Put Off the AC Thermostat

Close the AC indoor regulator and the actual AC. The inability to carry these out before fiddling with the AC breaker switch might bring about issues like damaging the CB. 

Assuming that the indoor regulator is as of now on, the forced air system will begin taking off and disrupt the reboot when the breaker is reset.

#3. Step 3: Find and Restart the AC Breaker Switch

Investigate your property’s wiring outline to understand which circuit breakers on the board are connected to the Air Conditioner.

There could likewise be names on the actual board for every machine. When found, switch off the AC electrical switch.

Sit tight for a couple moments before exchanging the HVAC electrical switch to the on position. Then, you should hear a perceptible ‘click’ if the breaker’s switch is securely placed.

Then, at that point, check, assuming the issues continue with your forced air system. Stand by to some extent, 30 minutes before beginning the AC.

Assuming you experience problems with the machine, you might have to supplant it. For example, finish this choice if the Air Conditioner won’t come on after turning on the breaker.

Observe that you will not be forced to reset the AC’s electrical switch to reestablish the machine’s legitimate usefulness.

For example, you could have to locate and press the reset key on the AC’s cooling unit.

Can an HVAC AC and Furnace be on The Same Circuit Breaker?

If you have a constrained air unit and focal air, the climate control system and the heater will be essential for your home’s HVAC framework.

Be that as it may, the AC framework works free from the heater. Regardless, the heater and AC unit utilize similar dispersion frameworks, like the vents and air pipes.

The wiring for an AC and heater is often taken care of by one focal unit known as a terminal box.

This terminal box will be introduced close to the heater and climate control system. Each wire will head out from the terminal box to the two apparatuses.

Those with a heater and an AC unit are doubtlessly wired by wire integrating them. In any case, that doesn’t imply that they fundamentally share any standard parts or parts.

While the heater is liable for directing your home’s temperature throughout cold weather, it likewise has indoor air quality. 

The blower removes the whole quantity of dampness and moisture inside your home. This adds to keeping you solid.

However, it can decrease the possibilities of buildup and form development. The blower engine gets into place when it isn’t showing a damp delicate part called a draft inducer.

The motivation behind this little device is to give a water/airproof seal that keeps hot or cool air from getting away from around the heater’s entryway or through the ventilation work before it goes into the room.

To the extent that a heater’s blower goes, it isn’t intended to act as a forced air system. Nonetheless, it will work during warm climate months if your unit has a convertible plan.

When your home gets hotter, the temperature sensors on the blower engine will advise it to change from warming to cooling.

Ultimately, the capacitor in your heater is intended to work with the blower engine. Its motivation is to give power when the indoor regulator calls for cooling or warming.

It likewise attempts to keep a consistent voltage in your framework. How your heater and AC are set up on your breaker will rely upon your home’s warming and cooling units.

For instance, if you have a heater with an AC unit, your breaker can be set up to the two units on a similar circuit.

Nonetheless, a few homes have different frameworks for each warming and cooling framework.

This implies that their forced air system can be fueled off without influencing the heater’s exhibition. Their association depends on your framework and whether an expert sets it up.

So, here are the disparities between an HVAC and an AC:

Refers to the entire system,Just one unit
Heating, Ventilation, and Air Conditioning AC only


In conclusion, if you have two separate units, it’s essential that the wiring is set up correctly between them.

In addition, the two units should be on their devoted circuit to try not to over-burden your home’s electrical framework and harm the gear.
