Your HVAC system works hard year-round to keep your Sacramento home comfortable, especially during hot summers and cool evenings. But like any major system, it can run into problems. Knowing the most common issues—and a few simple troubleshooting steps—can help you stay comfortable and avoid unnecessary stress. At Three Rivers Heating & Air, we’ve been serving Sacramento families since 1981, and we’ve seen it all. Here are some of the most frequent HVAC problems and what you can do about them.
Problem 1: HVAC Won’t Turn On
Nothing is more frustrating than your system refusing to start. Before calling for service, check your thermostat settings to make sure it’s on the right mode (heat or cool). Then, inspect the circuit breaker to ensure the unit has power. If these basics don’t solve it, it’s time to call Three Rivers Heating & Air for professional help.
Problem 2: Weak Airflow
Poor airflow often points to a clogged air filter or blocked vents. Start by replacing or cleaning the filter—most should be changed every 1–3 months, especially in Sacramento where air quality can fluctuate. Also, make sure your vents are open and unobstructed. If airflow is still weak, there may be a problem with your ductwork or blower motor.
Problem 3: Strange Noises
Rattling, banging, or screeching sounds can signal loose components, motor issues, or debris caught in the system. Turn off your unit right away to prevent damage. While you can check for loose screws or visible obstructions, most unusual noises require a licensed technician’s attention.
Problem 4: Uneven Temperatures
If some rooms are too hot while others are too cold, it could be a thermostat calibration issue, leaky ductwork, or even an improperly sized system. Try adjusting vents to balance airflow, but if the problem persists, Three Rivers Heating & Air can perform a full evaluation to identify the root cause.
Problem 5: High Energy Bills
If your bills are creeping up without an obvious cause, your system may be running inefficiently. Start with basic maintenance: replace the air filter, clean the outdoor unit, and check for debris around the condenser. If the problem continues, it may be time for a tune-up or even to consider upgrading to a more energy-efficient model.
