HVAC Troubleshooting Guide: Why Is Your HVAC System Blowing Hot Air?

Welcome to All Time Air Conditioning’s comprehensive HVAC troubleshooting guide. Here, we’ll guide you through the steps to understand why your heating, ventilation, and air conditioning (HVAC) system may be blowing hot air instead of cool air, in the simplest terms possible. By following our step-by-step process, you might save a hefty repair bill or at least understand when it’s time to call for professional help.

Step 1: Check Your Thermostat Settings

At times, the solution could be as simple as adjusting your thermostat settings. It might be that your thermostat is set to ‘heat’ instead of ‘cool’. Try resetting it and observe any changes.

Tips:

• Ensure that the switch is set on ‘AUTO’ instead of ‘ON’.
• If using a programmable thermostat, check if it’s programmed correctly.

Step 2: Inspect The Air Filter

Your next point of action should be the air filter. A clogged filter can cause inadequate airflow due to dust and debris build-up, which can ultimately lead to your system blowing hot air.

Suggested Actions:

• Regularly clean or replace your filters (once every 30-60 days).
• If you have pets or live in a dusty area, consider changing them more frequently.

Step 3: Look Out For Refrigerant Leaks

If both the thermostat settings and the air filter are in good shape, then you might have a refrigerant leak. A lack of enough refrigerant will make your system blow hot air instead of cool.

Spotting a Refrigerant Leak:

• You may notice hissing sounds coming from the HVAC system.
• A frozen evaporator coil is another possible sign of a refrigerant leak.

If you suspect a refrigerant leak, it would be best to contact All Time Air Conditioning professionals for repairs because dealing with refrigerants requires special handling and skills.

Step 4: Check For Blocked Condenser Unit

Last but not least, ensure that the outdoor condenser unit is free from any obstructions. Plants, debris, or dirt accumulated around your unit can cause it to overheat and consequently blow hot air.

Preventing A Blocked Condenser Unit:

• Keep plants at least 2 feet away from the condenser unit.
• Clean around and inside your outdoor HVAC equipment regularly.
