Why Is My AC Blowing Hot Air on One Side?

Your AC is blowing hot air on one side, it probably means that there’s a problem with the ductwork or vents.

You can fix this by checking the filters in your home and making sure they are clean.

If they’re clogged, you’ll need to replace them with new ones.

If they’re not clogged but still dirty, you can use a vacuum cleaner to clean them out.

If the filters are fine and you still have a problem with your AC blowing hot air on one side, then it’s likely that there’s an issue with the ductwork that is, some part of it has been damaged or punctured by something sharp.

You’ll want to call an HVAC technician who can come out and take a look at your system.

Where is the car AC unit located?

The car air conditioning unit is located in the engine compartment, at the rear of the vehicle.

The carAC unit is typically mounted on top of or behind the radiator, or it may be mounted low in the engine compartment beside or beneath the engine.

Such as pickup trucks and vans, there may be two separate units: one for heating and one for cooling.

What is the problem?

The way that an AC unit works is that there are two fans inside of it one to blow air out, and one to draw it in.

When the air blows out, it’s cool when it draws in, it warms up.

The way that these fans work together is controlled by a microchip, which tells them when to turn on and off.

Check Your Refrigerant Levels

If your air conditioner is blowing hot air on one side, the first thing to check is your refrigerant levels.

Refrigerant is what keeps your AC working, and if it’s low or empty, you will not be able to get cool air from your unit.

If you suspect that your AC has low refrigerant levels, you should call an HVAC technician immediately.

The technician will be able to check the levels of your refrigerant and possibly recharge them if necessary.

Is the Air Filter Dirty?

If your air conditioner is blowing hot air on one side, it could be because the air filter is dirty.

If this is the case, you should replace your filter as soon as possible.

Cleaning and drying the filter will not solve this problem and will cause it to happen again in a short period of time.

You can find replacement filters at most hardware stores for about $10-$20 depending on size and brand.

Check Your Thermostat Settings

The most common cause of hot air blowing on one side is that your thermostat has been set to heat instead of cool.

This can happen if you switch seasons without resetting your thermostat, or if the settings are just wrong.

You’ll need to access your HVAC system’s controls and flip the switch that says cool or heat.

Is Your Electric Compressor Running?

Check whether or not your electric compressor is running, turn off your breaker and unplug any extension cords that may be connected to the unit.

You should hear a humming noise coming from inside the unit when you do this.

If you do not hear any noise at all, then there is a problem with your electrical system.

You should contact an electrician right away so they can come out and fix your AC unit as soon as possible.

Check the fan motor

The most likely cause of your AC blowing hot air on one side is a faulty fan motor.

To check this, turn off the power to the unit and remove the cover.

If you see a problem with the fan motor or any other part, you’ll need to replace it.

What to do if your AC is blowing hot air on one side?

Turn off the power to your air conditioner. Open up the cover of your air conditioner.

You’ll find this in the same place as where you found your fuse box usually near your fuse box or electrical panel. You’ll need a screwdriver for this part!

Check for any obvious problems with your thermostat.

If you don’t see any damage, check that all wires are intact and hooked up correctly.

Make sure that none of them have been pulled out of their slots or broken off at any point during installation or repair work done before yours started blowing hot air again!

Conclusion

Your AC is blowing hot air on one side because the thermostat is set incorrectly, or because the thermostat is broken.

If you can feel a difference in temperature between sides of your AC, then it’s most likely that the thermostat isn’t set correctly, and that you need to adjust it.
