With summer coming, air conditioning in New Albany and Gahanna is an important element of a relaxing and enjoyable season. But one question that might be on the minds on homeowners as summer approaches is, “Why is my air conditioner not blowing cold air?” The following are two common problems.
No Cold Air
If air is coming out of the vents, but is not cold, a homeowner might do the following:
1. Check the setting of the thermostat fan. If it is running cold air at times and hot air at other times, it might be because the setting is not on “auto”; it might just be set on “on”, which will cause air being blown that is not cooled.
2. Check the air filter. Air might be coming out of the supply vents that is not very cool and somewhat weak; the air filter may be dirty and might need to be changed. Dirty air filters are known to block the flow of air to the handler.
If neither of these are the cause of the problem, the unit might be low on refrigerant; there might be a leak that has been undetected. A professional should be called in to help with this problem.
No Air Being Blown
If the unit is not working, and no air is coming through the vents, the following steps might be taken:
1. The thermostat temperature needs to be checked. It should be below the room temperature by at least 5 degrees.
2. The thermostat must be set to “Cool”. Sometimes pets or family members might inadvertently switch the setting to “Off” or “Heat”, which could result in the problem.
3. The air filter should be checked. If it is too dirty, airflow will be blocked completely. It needs to be changed with a new air filter that is the correct size.
4. The electricity going into the air conditioner should be checked. Common places to check include:
● At the outside AC unit, by the compressor
● At the air handler in the inside AC unit (This is typically near the furnace)
● At circuit breakers or fuses in the electrical panel
If any of these switches are set to the “off” position, the air conditioner may have a problem. An example of this is that if a water sensor switch is clogged, it will shut down to prevent water damage to a home.
The air conditioner might also be overheating and making the air conditioner pull in more electricity that the circuit breaker is made to handle. If the circuit breaker turns off, it is a sign that something is wrong and should not be ignored.
