Low Air Flow Spells Trouble for Your Air Conditioner

Here in Brea, CA, we’ve already experienced our share of heat, and that’s only going to get worse as spring turns into summer. Now is an excellent time to check your air conditioner for any signs of trouble. One of the biggest is a reduction in air flow, which usually signals a significant problem and if left unattended case eventually result in a full-bore breakdown. Any signs of reduced air flow in your system, and you should turn off the AC and call for professional assistance immediately. The causes of low air flow can illustrate how difficult the issue can be.

Fan Problems

The fan motor runs the fan that blows cool air into your home, and if it suffers damage, the fan won’t turn. The fan belt can also break or become loose, and sometimes the fan itself is the problem: bent out of position or suffering broken blades. Regardless, it can cause much more serious problems until addressed. The cool air just sitting in your system can cause the coils to freeze up, which can result in a much more expensive repair if you don’t get the core problem fixed.


Sometimes, the power blowing the air isn’t the problem. Instead, it’s the presence of a blockage somewhere in the system, a clogged air filter or even a duct breach pulling conditioned air out of the system. Either way, the ultimate result is the same as a lack of fan power: the air conditioner must expend more effort to do its job, and the cool air building up in the system could damage other components. The good news is that the problem is often less dire than it would be with a fan or fan motor problem, and the technician can usually identify and repair without excessive difficulty.
