Ensuring Your AC System Is Working How It Should Be

Posted on July 20, 2017

So far, the weather this summer has been up and down; the rain may have put a damper on things, but the heat has still found a way to make it through. Effectively keeping the home cool is important and an air conditioning system is a great way to do it, however sometimes there could be issues in your home or with the device which conspire to keep it from working at an optimal level.

Here are some common reasons why your air conditioning system may not be working at a top level, and what you can do to improve it:

Dirty Filter

If it’s been more than a couple of months since you’ve replaced the return-air filters in your AC system, they may be clogged and dirty, which can affect air flow. When filters get clogged with animal fur and dust, the AC system can’t draw in sufficient air, and as a result, only a wimpy flow of air comes out. So remove a return-air filter and, if you can’t see what’s on the other side, replace it.

Clogged Condensation Drain

Air conditioners work in part by removing humidity from the air (through condensation), and that moisture must go somewhere. That’s the job of a condensation drain hose—it directs water to a floor drain or to the outside of your home, depending on your system. Condensation drains are subject to blockage by mold and algae growth. When this happens, some AC units will stop cooling while others will shut down completely. Locate the end of the condensation drain line (often in a utility room) and visually check it for clogs.

Duct Malfunction

In a central AC system, the main blower forces cold air through the ducting and from there into individual rooms. If a duct somewhere between the blower and a room register (the metal grill that covers the opening of an HVAC duct) has broken, the cold air could be blowing out before it reaches the room’s register. If cool air is blowing from some registers but not from others, there’s a good chance the ducting that feeds the registers is at fault. If you have a basement, you can examine the ductwork to see if a joint has come loose. If so, refit the ends of the joint and tape the new joint securely with duct tape. If a ducting joint has come loose within a wall, however, you won’t be able to locate it and will need to call an HVAC professional. (Glenda Taylor, bobvila.com)
