Common Heating Problems in San Francisco Homes

Heating systems rarely fail without warning signs. Catching problems early saves money and keeps you ahead of the coldest nights. Here are the most common heating issues we see in San Francisco, CA, homes:

• No heat or insufficient heat: A furnace that runs but produces little warmth often points to a dirty heat exchanger, a failing ignitor, or a gas supply issue that needs prompt attention
• Short-cycling: When your heating system turns on and off too frequently without completing a full cycle, it usually signals an oversized unit, a dirty filter, or a failing thermostat
• Unusual noises: Banging, squealing, rattling, or booming sounds from your furnace or boiler each indicate specific mechanical issues ranging from loose components to heat exchanger cracks
• Pilot light or ignition problems: A furnace that won’t stay lit or fails to ignite reliably is a safety concern as much as a comfort issue
• Uneven heating throughout the home: Certain rooms staying cold while others are warm often points to duct problems, a failing blower motor, or an improperly sized system
• Sudden spike in energy bills: A heating system working harder than it should to maintain your set temperature almost always has an underlying efficiency or mechanical problem
• Boiler leaks or pressure issues: Water around the base of a boiler or erratic pressure readings are early signs of a problem that worsens quickly if left unaddressed

If your home is showing any of these signs, getting a technician to look at it sooner rather than later is the most cost-effective approach.
