When you get an air conditioner, you expect it to run exactly as it’s designed. That means it needs to provide cool air efficiently. If your AC system is no longer cooling the house as it should, then it’s time to take a look at it. You can see what you can fix on your own, and determine if you need a professional to help you.
There can be many reasons your AC is not blowing cold air. We’ve narrowed it down to four major possibilities.
One reason that your home AC is not blowing cold air is because the air filter is dirty or clogged. The air filter does more than just keep out particulates (though those can clog it, too). It also keeps out bigger debris like leaves, grass, dirt, and hair. So, while you may think that it’s just catching pollen, it does considerably more than that. And if it’s clogged, then your air conditioner is not cooling the way it should.
And you need to make sure that the problem doesn’t get worse than just a clogged filter. When the filter is clogged, your air conditioner works overtime to try to cool down the house, and the fans, evaporator coils, and condensers can all wear out. And that repair will be more costly than simply changing the filter.
Fortunately, in almost all cases, changing the home AC unit’s air filter is something you can do without having to call a repair professional.
The thermostat can be set to cool your home, but if the thermostat isn’t working, then the central AC is not blowing cold air–and your house gets hot.
The problem can be something as small as checking to make sure that it hasn’t been set to heat by accident, or the problem can be that the thermostat has broken and needs to be replaced, or the batteries need to be checked (if it takes batteries). If you’ve checked the settings and the batteries and it’s still not working, then call a professional to get a new thermostat installed.
If you’re wondering why your AC isn’t cooling, and everything seems to be in working order, check all the vents. It might be that some of the vents have been closed. In that case, it’s simple to open them or move any furniture or boxes that have been placed in front of them.
Because the vents run throughout the house, the blockage could be anywhere, and even one blocked vent could slow down the operation and make the air conditioner run less efficiently.
A frozen evaporator coil can completely shut down your AC. This happens if there’s a refrigerant leak, or if the refrigerant levels are off. This is generally not a problem that you can fix on your own unless you have a lot of experience, and you’ll need an HVAC professional to come work on the evaporator coil.
While you’re at it, check the condenser, which will wear out over time.
