AC Troubleshooting in the Spring

Posted on

In a tough economy, the last thing you need is a surprise AC repair. Well, maybe the last thing you need is having your air conditioner break down just as the 90-degree heat hits Gaithersburg, Germantown, Potomac, Clarksburg, and the entire Montgomery County, MD area. In any case, the expert AC technicians at Michael Bonsby Heating & Air Conditioning have identified the most common AC problems homeowners in the area deal with every spring.
Troubleshooting AC Problems in the Spring

In no particular order, here the most common springtime AC problems and what you can do to address them:

Tripped Breaker

If your AC unit isn’t cooling your home, the problem could very well be due to a tripped breaker. Try resetting it before calling us. If this doesn’t solve the no-cool problem, it’s possible your unit has a faulty breaker, loose wire, or a bad capacitor. This is a pretty easy fix for a top AC technician. If you do not address the problem, however, simple problems could lead to far more expensive AC repairs down the road.

Clogged Drain Line

AC units pull moisture out of humid air while lowering the temperature. The moisture is typically drained out of your home through your plumbing system. A drain pan should be present as a backup with a secondary condensate drain. Algae can grow in these lines, clogging them up—which can lead to serious water damage in your home. As part of our spring AC tune-up service, we clear the unit’s drain lines.

Dirty Condenser Coil

The condenser coil is located outside your home, and it pulls hot refrigerant gas from the evaporator and pumps it through the outdoor coil where it condenses into a liquid as the condensing unit fan pulls air across the coil. A dirty condenser coil is inefficient, increasing electricity usage and reducing system cooling capacity. As part of our tune-up service, we wash, clean, and if necessary, comb the condenser coil.

Dirty Evaporator Coil

The evaporator coil is an essential piece of your air conditioning system. It absorbs heat from air that passes over it, and that air then travels into your home to cool it. So if your coil is dirty or isn’t functioning properly, the cooling power of your system is diminished. One of the most obvious signs of a dirty evaporator coil is an overall drop in system pressure. Dirty coils increase operating costs while reducing home comfort. The hardest part about cleaning an evaporator coil is reaching it. Unlike the condenser coil, which is located in your outdoor condenser unit, the evaporator coil is found inside near the air handler furnace. If you have the owner’s manual, there should be detailed instructions explaining where the coil is and how to safely access it.

You can also contact us for evaporator coil cleaning—it’s an easy job for a professional AC technician.
