5 Common Reasons Why Your AC Is Blowing Hot Air
The heat can be deadly. In fact, the United States Environmental Protection Agency estimates that around 1,300 deaths per year may be attributed to heat-related illnesses. In these cases, an air conditioner is literally lifesaving.
Sitting or working in a hot environment for too long puts people at risk for fatal heat-related illnesses. An air conditioner is almost necessary in the hotter parts of the world. Who knows how people survived thousands of years before they were invented.
If your AC is blowing hot air, you don’t have to go without, just check it for these common issues.
1. Loss of Electricity
If the indoor unit is able to blow air, that means the electricity to that unit is functioning. If that air is hot, however, it may signal an issue with the corresponding outdoor unit. These two units need to work together to cool down a home.
Check the circuit breaker in the home for a tripped or blown fuse. These electric issues need to be remedied by a professional. Electrical issues account for over 300,000 home fires each year.
2. Dirt and Debris
Maintaining the outside air conditioning unit is part of good AC maintenance. It’s easy to do, and avoiding the issues that follow a clogged condenser may save a lot of money.
Outside units need to pull in air to run it through the refrigerant and deposit cold air inside the home. If the outside unit is clogged, it won’t be able to pull air in. Keep the area around the unit free and clear. While you’re at it, check the air filters.
3. Airflow Problems
Airflow problems are best diagnosed and treated by an HVAC professional. If the culprit is not easily visible like debris on the outside unit or a dirty air filter, an expert needs to get inside the system to check the ducts, coils, and vents.
Over time, these parts commonly accumulate dirt and debris and need to be cleaned.
4. Refrigerant Volume
Refrigerant is what makes warm air cold. It’s the same stuff used to keep a refrigerator cool, thus its name.
Low refrigerant volume or a refrigerant leak will prevent air from cooling enough. It is difficult to identify the source of a refrigerant leak without the help of a professional.
5. Incorrect Settings
It may sound unlikely, but there have been cases of homeowners setting their thermostat incorrectly. This is more common for those with a brand new HVAC system. Consult a manual or HVAC professional to make sure the best settings are selected.
