If things go wrong with your cooling system, how much air conditioner troubleshooting should you attempt? Where’s the tipping point when it comes to when to call in a qualified professional, instead?

The fact is, technology incorporated in today’s central air conditioners is complex and beyond the expertise of the average homeowner. For this reason, as well as safety concerns and warranty restrictions, the list of DIY air conditioner troubleshooting is necessarily short.

Nevertheless, a few basic steps eliminate obvious issues and narrow down causes. Let’s review some common AC issues and air conditioner troubleshooting steps.

Common AC Problems for Cincinnati Homes

AC doesn’t start at all

First, check the thermostat and make sure the system’s in “Cooling” mode. Little buttons and levers easily shift. Also verify the desired temperature setting is at least five degrees below the displayed room temperature.

If everything appears correct, look inside the main electrical panel for any tripped circuit breakers. If you notice one, don’t reset it.

Call a qualified HVAC contractor for assistance. HVAC systems are a common source for internal power surges. If there’s an electrical problem, let a professional handle it.

AC runs but low airflow

Inspect the system air filter. Does it appear dusty and dirty? Remove the filter and install a new one. Check the airflow. Also, make sure nothing’s obstructing vents on the outdoor half of the A/C system.

Fallen leaves or objects someone placed on top of the fan grille obstruct air flow, as well as weeds or other vegetation.

Resist the temptation to plant things around your AC compressor. It may not be pretty, but trying to camouflage it with plants, shrubs or fencing creates new problems. If the airflow problem persists, call a pro.

AC stops and starts without cooling the whole house or AC starts and stops a lot

When HVAC equipment frequently starts and stops without fully cooling or heating the house, it’s short cycling. This occurs for many reasons.

Sometimes it’s a thermostat or electrical control problem. The thermostat might need to be moved, replaced or recalibrated.

Sometimes, the filter is so dirty, the blower motor overheats and shuts off. It overheats because it’s trying so hard to push air through the clogged filter.

In some cases, the air conditioner, heat pump or furnace is the wrong size for the house. Bigger is not always better when it comes to heating and air conditioning units.

Schedule a tune up with a trusted HVAC contractor like Apollo Home. Every tune up begins with a top to bottom inspection, which should identify the source of the short cycling.

Water around or leaking from air conditioner

If you notice water around the indoor air handler, check the condensate drain pan situated underneath. The air handler is the inside housing of your air conditioner. It contains all the indoor AC components. The AC compressor is the major outside piece.

Is standing water inside the pan? If so, you could have overflow from a clogged condensate drain line. A qualified HVAC technician must clear the clog.

Another possible cause of leakage around your AC is ice on the evaporator coil inside the air handler. This is a common result of a very dirty coil or low refrigerant level. Both situations require professional service to diagnose and fix.
