The heat in Livermore, CA, makes it especially important to have a properly functioning air conditioner. When summertime temperatures soar, people want to escape to their cool homes. When your AC isn’t blowing cold air, is making strange noises, or the humidity level is high, you might begin to suspect your air conditioner is no longer functioning properly. Before you call our team, check your thermostat settings and air filter. These are common quick fixes, but if they’re not the problem, it’s time to reach out to Eagle Air Conditioning for assistance.
Check the Airflow from Your Vents
Have you ever asked yourself, “How does a heat pump work?” Heat pumps offer year-round comfort just like a traditional HVAC unit. Whichever type of AC you have, your first step is to ensure that cool air is coming out of your supply vents.
If you don’t feel consistent airflow or temperatures throughout your home, the blame may lie with your ductwork and/or your insulation. Other problems that can cause weak or nonexistent airflow include a frozen evaporator coil, low refrigerant levels or a faulty blower motor.
Monitor the Temperature Difference
Energy-efficient heating and cooling rely on noticeable temperature differences. To determine whether your AC is working properly, turn it on and let it run for 15-20 minutes. Next, take a digital or infrared thermometer and measure the temperature at your closet supply vent and return vent. Subtract your supply vent temperature from the return vent, and you’ll get your answer.
A properly running AC will have a difference of between 15-20°F. However, if you register only a small or no real temperature difference, the issue might be with your heat pump heating and cooling system. Possible causes include a blower motor issue, low refrigerant, a dirty evaporator coil or even improperly sized ductwork.
Inspect the Thermostat Settings and Functionality
Take the time to verify your thermostat is set to cooling mode at the right temperature. It’s also necessary to check that your thermostat display is working properly. Thermostat issues can affect proper AC operation, which means the air source from your heat pump won’t match your needs. Reasons for this include:
- Low batteries
- Defective thermostat
- Wiring issues
- Placement problems
- Miscalibration
- Dirty/old thermostat
- Tripped circuit breaker
Listen for Unusual Noises
The normal sounds that come from an AC unit include clicking when it turns on and off, a gentle whooshing of air and a low hum. What if you hear grinding, rattling or buzzing noises, though?
A buzzing sound indicates an electrical issue, such as motor problems or a failing capacitor. A hissing sound typically indicates a refrigerant leak. Rattling or banging noises can range from loose parts to a broken compressor component. Finally, a grinding noise could indicate a worn-out fan motor bearing or a damaged fan blade.
Examine the Outdoor Unit
Taking a look at your outdoor unit can help you determine what’s wrong with your AC. Be sure to check if the condenser fan is running. Also, don’t forget to look for any blockages or debris around the unit. Signs of overheating or unusual behavior may include:
- Warm air from your vents
- Frequent cycling
- Burning smell
- Strange noises
Check for Water Leaks or Excess Moisture
Condensation, drainage or potential clogs often lead to noticeable water leaks. If your indoor unit is leaking, it could mean you’ve got a malfunctioning condensate pump. Other possible reasons include a rusted drain pan or a dirty air filter. Make sure you schedule regular heat pump maintenance to help prevent these issues.
Review Your Energy Bills
If you’ve noticed an unexpected spike in your electricity usage, it could be a sign of inefficiency. According to the Department of Energy, having a simple clogged or dirty filter can raise your energy consumption by 15%. Furthermore, you could face increased maintenance costs.
When to Call a Professional HVAC Technician
Signs that you need an expert diagnosis and repair include musty or foul odors, weak airflow, warm air, humidity issues or your system not turning on at all. Again, this helps highlight the importance of regular preventative maintenance to prevent issues.
