Dealing With AC Suddenly Ceasing To Blow Cold Air: Steps To Take

When the heat of summer is at its worst, a functioning air conditioning system becomes necessary to keep your home cool and comfortable. However, there may be instances when your AC suddenly stops blowing cold air, leaving you uncomfortable and frustrated. However, you can follow various steps to troubleshoot and fix the problem.

Here are several tips on what to do when your AC suddenly stops blowing cold air:

Check The Thermostat Settings

The first and simplest step is to ensure the desired temperature is set on your thermostat. It’s not uncommon for settings to be accidentally changed, causing the AC to blow warm air. Verify that the thermostat is in the “cool” and adjust the temperature lower than the current room temperature to trigger the cooling cycle.

Inspect The Air Filters

Clogged or dirty air filters can hinder proper airflow, reducing cooling performance. Check your air filters, and if necessary, clean or replace them. A clean filter promotes optimal air circulation, allowing your AC to blow cold air effectively.

Examine The Condenser Unit

The condenser unit outside your home plays a vital role in the cooling process. Ensure the unit is free from debris, such as leaves, grass, or dirt, as they obstruct airflow and impede cooling efficiency. Additionally, check if the condenser fan is running smoothly. If you notice any issues or suspect a malfunction, it’s advisable to seek professional help from Unique Heating & Cooling Inc. for a comprehensive inspection and necessary repairs.

Verify Circuit Breakers And Power Supply

A tripped circuit breaker can disrupt the power supply to your AC unit, resulting in no cool air. Check your electrical panel and reset any tripped breakers related to the AC system. Additionally, ensure that the AC unit is receiving power by verifying the switch near the outdoor unit is in the “on” position.

Consider Refrigerant Levels

Insufficient refrigerant levels can significantly impact your AC’s cooling performance. If you suspect a refrigerant leak, it’s crucial to contact Unique Heating & Cooling Inc. for professional assistance. Handling refrigerant requires specialized knowledge and equipment, so our trained technicians can accurately diagnose any leaks, repair them, and recharge the refrigerant to restore optimal cooling capacity.

Assess Ductwork And Airflow

Leaky or poorly insulated ductwork can result in cooled air escaping before it reaches the desired areas in your home. Look for any obvious indicators of deterioration in the ducting, such as loose connections or gaps. Also, check if obstructions are blocking the air vents or return registers.
