Nothing is more frustrating than feeling a warm breeze from your vents when you are expecting a refreshing blast of cool air. In the intense Arizona heat, a malfunctioning air conditioner is a major disruption to your daily life. At Aristotle Air, we know that understanding the common culprits helps you decide when to call for help.
Check Your Thermostat Settings
Before worrying about a major mechanical failure, we suggest verifying that your thermostat settings are correct. It is surprisingly common for a system to be accidentally switched to the heat position or for the fan to be on the wrong setting. Adjusting these simple controls ensures your system only blows air that has been actively cooled.
Inspect for Clogged Air Filters
We cannot overstate the importance of clean filters for proper airflow. When a filter is heavily clogged with desert dust, it restricts the air moving over your evaporator coils. This restriction can cause the system to overheat or the coils to freeze solid, ultimately resulting in lukewarm air blowing through your home’s ductwork and increasing your energy bills.
Identify Potential Refrigerant Leaks
Refrigerant is the essential fluid that absorbs heat from your indoor air. If your system leaks, the remaining refrigerant cannot effectively remove heat, leading to a noticeable temperature rise at the vents. We recommend watching for hissing sounds or ice buildup on the copper lines, as these are clear indicators that your unit requires professional attention.
Examine the Outdoor Condenser Unit
Your outdoor unit must be able to release heat to the outside environment to keep you cool inside. If the condenser coils are caked in dirt or the fan motor has failed, the heat exchange process breaks down. We often find that clearing away debris and ensuring the unit has adequate breathing room can restore the cooling performance you expect.
