Is Your AC Blowing Hot Air? Here Are Some Common Reasons

You installed your air conditioner to do just one thing; cool your home, so that you could live in comfort and convenience even during sweltering, muggy summer nights that would otherwise make it difficult even to sleep.

That’s why when things go wrong, especially in the summer, you need to fix them quickly.

If you turn on your air conditioner and you find that you’re getting warm air pumped through your home instead of the cool air you were expecting, that’s a sign that something is very wrong. Try answering these three questions to get to the bottom of the problem.

Are Your Fuses Working?

If you have centralized AC, some models will work with a separate fuse system to help control power surges or other disruptions that could seriously damage your hardware.

If you’ve had a power surge or any other electrical incident, this may have blown the fuses located near your AC’s condenser unit outside.

This means that even though the fan in your furnace is doing its job and pumping air throughout the house, the condenser outside your home and the fan in that condenser aren’t doing their jobs.

Check the fuses to see if they’re still working. If not, it’s time to replace them.

Is Your Condenser Icing Up?

This seems like an unbelievable occurrence, but it’s possible that your AC is cooling down air in the wrong place, and it’s causing your condenser to freeze.frozen

Sometimes, when things go wrong with the AC, the first place to look is your condenser.

If you see that ice and icicles are forming on it, that means none of that cooling power is going into your home, it’s being all wasted outside.

The condenser freezing has a variety of different causes.

An array of mechanical defects could be behind it, or it could be a blockage in the air flow that is preventing the cooled air from traveling back into your house.

Whatever the cause, get a professional to look into it.

Are You Leaking Refrigerant?

The “blood” of your AC unit that needs to be pumped in order to ensure smooth operation is called refrigerant. It works through an ingenious exploitation of certain physical phenomena.

Some substances, when changing states from liquid to gas, produce, as a side-effect, a characteristic ability to absorb heat, leaving only cold air in the aftermath. AC units exploit this principle, constantly changing a refrigerant from liquid to gas and back again, in a never-ending cycle that creates cool air.

That air is then pumped into your furnace, where the furnace fan blows it throughout the home. If you’re leaking refrigerant, this process can no longer continue so that you may need more.
