5 Common Heating Problems You Need to Know

When the temperatures start to drop in the Bay Area, the last thing you want is a heating system that refuses to cooperate. Whether you rely on a furnace, heat pump, or another system, even minor issues can disrupt your comfort and cause your energy bills to spike. At Comfort Energy, Inc., we help homeowners identify and address common heating problems early—before they turn into costly repairs.

Here are some of the most common heating problems and how to troubleshoot them:

1. Heater Won’t Turn On

If your heater isn’t powering up, check your thermostat first. Make sure it's set to “heat” mode and that the temperature is set higher than the current room temperature. If that looks good, check the circuit breaker—sometimes a tripped switch is the culprit. If all settings are correct and it still won’t turn on, it’s time to call a pro.

2. Insufficient Heat

If your system is running but your home still feels cold, several issues could be to blame. A dirty air filter can restrict airflow, reducing the system’s ability to heat your space. Try replacing the filter and see if performance improves. If not, your unit may have a malfunctioning thermostat, pilot light issue, or leaky ductwork that needs professional attention.

3. Uneven Heating

Are some rooms freezing while others are toasty? Uneven heating is often caused by blocked vents, poor insulation, or issues with your ductwork. Walk through your home and make sure all vents are open and unobstructed. Still uneven? Have Comfort Energy, Inc. inspect your system to pinpoint and resolve the issue.

4. Unusual Noises

Pops, bangs, rattles, and screeches—none of these should be coming from your heater. Loud or strange noises often indicate loose components, worn-out parts, or airflow problems. Don’t ignore the sounds—early intervention can prevent bigger damage.

5. Short Cycling

If your heater keeps turning on and off frequently (a behavior called “short cycling”), it could be due to an oversized system, a clogged air filter, or a malfunctioning thermostat. Short cycling reduces efficiency and puts unnecessary strain on your equipment. A technician can quickly diagnose and fix the issue to restore proper function.
