Once the hot Pennsylvania weather hits, you need a reliable air conditioning system to keep you cool and comfortable. If your AC system is blowing out air, but it’s not cold, your unit is most likely in the market for a repair service. What are some of the reasons that your AC is blowing warm or room-temperature air?
Issue With the Refrigerant
Refrigerant is a necessary part of an air conditioner, as it sets the whole chemical process in action. The refrigerant is what makes the air in an AC unit cold, so if it’s not, it may be running low. It may simply need to be refilled, or it could be due to a leak, which would need to get fixed as soon as possible.
Filters are another essential part of an AC unit that need to be working properly for the whole system to be working. Filters collect anything circulating in the air, including pollen, dust, hair, lint, and any other dirt particles. If the filter isn’t changed, then these particles remain in the filter, and the air can’t flow freely through the filter into your home.
In addition, a dirty filter can negatively impact the evaporator coil and condenser, making an even more complex issue. Filters should be changed at least every three months to keep this from happening.
Problem With Evaporator Coil
Just like with the rest of the parts of your AC unit, condenser coils can become dirty or break down over time. The filters play a role in keeping the coils clean, but if they wear down, your AC won’t work at optimal efficiency. Constant moisture in the unit can cause issues with the evaporator coil such as mold and mildew.
Low refrigerant levels can also cause the coils to freeze up. Therefore, when the air coming out isn’t cold, the coils are a common culprit.
Issue With Thermostat
The thermostat is what controls the air conditioner, so if there’s a problem with it, then there will be a problem with the unit’s performance as a whole. The correct thermostat setting has to be on in order for there to be cold air blowing. It may be a fix as simple as turning the setting to “cool” or “auto” and ensuring that the AC is on.
It might be set correctly but still blowing warm air, which means that the thermostat may be faulty. If resetting it and changing the batteries don’t work, an AC professional will have to take a closer look to diagnose the problem.
