Vents Blowing Warm Air?

There is nothing worse than coming home to find your air conditioner blowing warm air. When the temperature is 3 digits outside, you need a reliable cooling system to keep you comfortable. In this blog we will answer the common homeowner question of “Why is my AC not blowing cold air?” and provide solutions to help get your air conditioner working properly!

There are many reasons why your air conditioner is distributing the muggy, warm Alabama air into your home. One of our trained technicians can help identify the problem and quickly get your home comfortable once again.

Your thermostat may be having issues.

If you notice your air conditioner blowing warm air, first check the thermostat settings. If your thermostat seems to be powered off, it may need a new set of batteries. If on, the thermostat should be set to cool and read a comfortable temperature. Best case scenario, someone changed your setting or temperature and you can go back to your air conditioner blowing cool air in no time. Unfortunately life doesn’t always work like that, so if everything seems to be working with your thermostat move to our next tip!

Your refrigerant levels may be low.

Refrigerant is critical to producing cool air in your home. It is likely the levels are low due to a leak, which can cause many other problems than just blowing warm air. If this is your issue, your air conditioner will continue to try to keep up with your temperature setting and blow warm air. We recommend contacting your Anchor Air technician to assist with this problem.

Your drain may be clogged.

Along with keeping you cool, your air conditioner is also tasked with dehumidifying your air. The moisture collected from your air goes out a drain pipe typically located near your outdoor unit. To check if your drain line is clogged, start with removing any visible debris. Deeper clogs can be removed by shop or wet vacuums or calling your Anchor Air technician!

Your condenser unit may be blocked.

Your outdoor unit is referred to as a condenser. Debris such as grass clippings, leaves, and branches can harm your air conditioner’s ability to function properly. Dirt and debris can cause your unit to overwork itself or produce a problem like blowing warm air. We recommend clearing any removable debris and carefully washing away the dirt with a hose, but to ensure it is done correctly give us a call.

Your air filter may be dirty.

Your air conditioner relies heavily on a clean air filter. A dirty or clogged air filter could be the source of many problems, not just blowing warm air. A dirty air filter harms airflow and makes it harder for your system to push cool air through. To keep your air cool and avoid a breakdown, change your air filter every 90 days or sooner depending on indoor pets.

Your evaporator coil may be frozen.

Much like the human body, all of the parts to your air conditioning system work together to keep you comfortable. If your evaporator coil is frozen and causing your unit to produce warm air, it could be due to a dirty air filter or clogged drain lines. Accessing your evaporator coil is a difficult process and best handled by an Anchor Air technician.
