AC Blowing Hot Air: 6 Causes and Solutions

Thermostat Settings

Check your thermostat settings to start with the most straightforward approach. Ensure that “Cool” mode is selected rather than “Heat” or “Fan.” Make sure the setting is lower than the ambient temperature as well. Try changing the batteries if the thermostat isn’t functioning properly, or hire an expert to address any underlying problems.

Unclean Air Filters

Clogged air filters might severely hamper the effectiveness of your AC’s cooling system. Dust, grime, and debris build up over time, blocking airflow and lowering effectiveness.

Ideally, you should change your air filters every one to three months, depending on usage. In addition to enhancing cooling, clean filters improve indoor air quality by lowering allergens and pollutants.

Low Refrigerant Levels

Your air conditioner depends on refrigerant to function. So, it might blast heated air if it is low on refrigerant. For an HVAC specialist to discover and resolve the problem, low refrigerant levels typically signal a leak. Without the correct training, handling refrigerant may be dangerous and further harm your air conditioner.

Defective Compressor

The compressor is in charge of maintaining the proper temperature and moving refrigerant. Instead of producing cold air, a broken compressor may produce heated air.

Visiting an HVAC specialist for diagnostic and repair is essential if you suspect a broken compressor. The compressor can be challenging to repair or replace on your own and may need professional equipment and knowledge.

Condenser Unit Problems

The condenser unit, which is normally outdoors, is essential for cooling your property. Warm air can be coming from your vents if it’s not working properly. Clean the condenser unit carefully after checking it for any debris, such as leaves or grass clippings.

Additionally, ensure the unit has enough room for optimal airflow and look for bent or broken fins. Contact a qualified HVAC technician for repairs if you see any serious problems.

Air Duct Blockages

Cool air may not be able to reach your living rooms due to blocked or obstructions in the air ducts. Check your air vents to make sure no furniture, carpets, or other items are blocking them. Additionally, look for any damage or obstructions in the ducting. To fix any problems, remove the impediments or hire a professional duct cleaning service to reestablish adequate airflow.

Don’t allow a hot air-blowing air conditioner to destroy your summer sanctuary with annoyance. With the help of this thorough troubleshooting guide, you are now equipped to address typical problems that could be keeping your AC from chilling properly.
