Does your AC blow out cool air sometimes and lukewarm air other times? Then the fan setting may be set to “ON” which just runs the fan 24/7—even when the air isn’t being cooled.

Solution: Set the thermostat to AUTO. A dirty air filter reduces airflow into your AC, causing several problems: Solution: Check the air filter and change it if it looks like the filter on the right Here’s how your AC cools your house: the air conditioner’s inside unit (called an evaporator) absorbs heat from your air and then transfers that heat to the outside unit (called the condenser). But the condenser can’t dissipate heat if it’s dirty or crowded with debris. This causes your air conditioner to struggle to cool your home. This condenser could use some cleaning. Solution: Spray the outside unit with a garden hose on a gentle setting. DON’T blast it on a high setting or you’ll bend the fins that allow airflow to cool the condenser off. Also, remove any weeds growing around the AC unit. Give it some breathing room! Here are just a few problems that a professional air conditioning contractor may need to fix: If the fan motor is bad, then the outdoor unit’s fan can’t help dissipate heat, meaning that the AC can’t cool your house.

Refrigerant is the liquid that absorbs the heat from your air. When you don’t have enough, your AC can’t absorb enough heat to cool the air. A low refrigerant level means one thing: you have a refrigerant leak. Signs you have a refrigerant leak include: If you see these signs, turn off your AC and call a professional ASAP. Running the AC in this state can cause slugging in the compressor and damage it beyond repair. The compressor is the heart of the AC system, circulating refrigerant like blood between the inside and outside unit. If it’s damaged, then the AC can’t cool your air. If there’s an issue with the compressor, then it may need replacing. Unfortunately the compressor is uber expensive.  So unless you have a warranty on it, you’ll probably need to replace an entire outside unit. Did you try solving the problem yourself?

If your home is equipped with a central air conditioning system you may have noticed a drain line on the outside dripping water near the air conditioner. This line drains condensation from the inside air handler to the outside. If this line clogs (usually from algae) it can cause water damage inside the house. You can prevent a clog by simply pouring a cup of household bleach into the line from the inside. To remove a clog once it has occurred, attach a wet/dry vacuum to the drain line outside (removing the paper filter first) and suck the clog out.

Like many household appliances, each of these components does their job both independently, but also in unison with the connecting parts and when one section of the system goes down, the entire performance falters.

While each component in a central air-conditioner is critical, quite simply the unit will not work if the fan is not running. Fans in the central A/C both pull air out of the room to be conditioned and have humidity removed and also push chilled air through the vents throughout the house. When the fan goes down there is no way to cycle the air and thus the system is essentially stalled. It’s important to get the fan up and running ASAP or else the home will get uncomfortable in a hurry and you could end up damaging the compressor. There are a few ways to tell if your A/C fan is temporarily or permanently out of order. The first is an inspection of the outdoor unit to physically see if the fan is turning. The condenser lines should be cold and the air inside the home should be cool. If the fan isn’t running at all or there is warm air blowing it’s time to troubleshoot: If the fan doesn’t start up at all it could be something as simple as a setting on the thermostat.

Make sure that the power is turned on and that the settings are calling for ‘cooling’. If all the settings are correct but the fan doesn’t start it could be an overheated or damaged fan motor. In some cases, you can give the fan a ‘kick start’ by pushing it with a stick and if this occurs there is likely an issue with the capacitor. Similarly, if a fan won’t turn when the power is on but will rotate freely when shut off it could be the sign of a bad motor bearing. Trouble with the bearing will also result in wobbly or lopsided turning if the fan does run. The fan needs to run at an optimal speed for the system to function properly. If the blade turns noticeably slower there may be low voltage running to the unit caused by issues with the control board or problems with the circuits. Also, the fan blade may have come loose from the motor shaft and is simply moving slowly because of a breeze or the turning of the shaft. Once again a capacitor may also be causing issues with the slow moving fan.

If your Central A/C fan is acting unpredictably, starting on and off at random and shutting down in the middle of a cycle it could be a sign there’s an issue with the wiring or some loose components somewhere. It’s normal for a fan to keep running for a short time after an A/C cycle while the compressor motor stops but a fan that keeps winding excessively there are likely problems in the circuit board or with the wiring. As long as the A/C unit is running properly some homeowners may be willing to ignore a ticking, rattling, or buzzing coming from the fan area. In reality, it’s best to diagnose these sounds to make sure they aren’t leading to serious problems down the line. The first thing to check is that an obstruction isn’t hitting the fan blades as they turn or that the blades aren’t bent. Buzzing and humming are somewhat more sinister as they could present a problem with the motor or the bearings turning the blades. The common denominator with all these problems is that, although a visual inspection might locate the problem, the fix should almost always be done by a professional HVAC technician.
