When the Bay Area nights turn cold, a reliable heating system isn’t a luxury—it’s a necessity. But like any hard-working appliance, furnaces and heaters can develop issues that interrupt your comfort. At A-1 Heating and Cooling, we’ve been helping San Jose homeowners resolve heating problems since 1983, and we know that a little troubleshooting can go a long way in restoring warmth to your home.
Uneven Heating in Different Rooms
One of the most common complaints from homeowners is uneven heating. Some rooms may feel warm and cozy, while others remain chilly. This can often be caused by blocked vents, leaky ductwork, or an improperly sized system. Checking vents and ensuring they’re not obstructed by furniture is a good first step. If the issue persists, a professional inspection may be needed to identify ductwork or sizing concerns.
Strange Noises from the Furnace
Popping, rattling, or squealing noises aren’t just annoying—they can be warning signs. Loose parts, worn-out belts, or issues with the blower motor can all cause unusual sounds. While tightening visible components may help, most of these problems require a trained technician to properly diagnose and fix them before they lead to larger breakdowns.
Furnace Won’t Turn On
If your furnace doesn’t turn on at all, it could be something simple like a tripped circuit breaker or a faulty thermostat setting. Double-check your thermostat to make sure it’s set to “heat” and replace the batteries if needed. If that doesn’t solve the problem, it may be due to more complex electrical or ignition system issues that require professional attention.
Weak or No Airflow
Poor airflow is another frequent issue and often points to dirty filters or clogged ductwork. Replacing your furnace filter every 1–3 months is essential to maintain good air circulation. If the filter is clean and the problem continues, there may be a problem with the blower fan or motor, which should be inspected by an HVAC expert.
Short Cycling
Short cycling occurs when your furnace turns on and off too frequently, preventing it from completing a full heating cycle. This not only reduces efficiency but also places unnecessary stress on the system. Causes can range from dirty filters and improper sizing to more complex issues with the thermostat or heat exchanger.
