As homeowners, few things are as frustrating as an HVAC system that simply won't cool your home. When your comfort is compromised, it's natural to wonder what's going wrong. At Atlantis Comfort Systems, we understand the importance of a properly functioning residential HVAC system. We've seen it all, and often, the culprits behind a lack of cooling are common issues that can be addressed. Let’s explore four frequent reasons your residential HVAC system might not be performing as it should.
4 Reasons Why Your Residential HVAC System Isn’t Cooling Properly
Dirty Air Filters
One of the most common and easily preventable reasons your residential HVAC system isn't cooling effectively is a dirty air filter. A clogged filter restricts airflow, forcing your system to work harder and reducing its efficiency. This can lead to decreased cooling capacity and increased energy bills. We always advise our clients to check their filters regularly.
Frozen Evaporator Coils
If you notice ice on your outdoor unit or your vents are blowing warm air, you might have frozen evaporator coils. This often happens due to restricted airflow (again, a dirty filter can be a cause!) or low refrigerant levels. When coils freeze, they can't absorb heat from your home, leading to a lack of cooling. Our residential HVAC services team can diagnose the underlying cause of frozen coils and thaw your system safely, ensuring proper operation and preventing further damage to your residential HVAC system.
Thermostat Malfunctions or Incorrect Settings
Sometimes, the issue isn't with your residential HVAC system itself, but with its control center: the thermostat. An incorrectly set thermostat or a malfunctioning unit can send the wrong signals to your system, preventing it from cooling properly. Ensure your thermostat is set to "cool" and the temperature is lower than your current indoor temperature.
Low Refrigerant Levels
Refrigerant is the lifeblood of your residential HVAC system, responsible for absorbing heat from your home and releasing it outside. If your system is low on refrigerant, it likely indicates a leak, which can significantly impair cooling performance. Low refrigerant can cause your system to work harder, leading to higher energy consumption and potential compressor damage.
When your residential HVAC system isn't cooling as it should, it's often due to one of these common issues.
