Common Heater Repair Issues
When San Jose temperatures drop, your heater should be ready to kick into gear. But even a minor hiccup can throw off your home’s comfort.
Here’s a quick look at the issues that most often lead to repair calls in the Bay Area.
Inconsistent Heat Distribution
San Jose’s climate can leave some rooms toasty while others stay cold. This usually points to deeper issues like poor duct design or zoning misfires. We go beyond the basics to make sure heat is distributed evenly throughout your home.
Strange Noises
Loud thuds or strange mechanical noises coming from your heater? That’s often a sign that something’s off inside. Our licensed technicians zero in on the problem using industry-leading tools and get your system running quietly again.
Thermostat Malfunctions
In the birthplace of Silicon Valley, we often see homes equipped with outdated or miscalibrated thermostats. Whether it’s an older analog unit or a new smart thermostat acting up, we get it reconnected and working seamlessly.
Cold Air Coming from Vents
If your vents are pushing out chilly air instead of heat, something’s up. Whether it’s a filter, pilot light, or heat exchanger, we look at the full system to fix the real problem, not just the surface issue.
Lack of Airflow
Reduced airflow can lead to uneven heating and system strain. This is often caused by clogged filters, duct blockages, or a failing blower motor, all things our team is trained to handle during a routine service call.
Pilot Light or Ignition Problems
If there’s no heat at all, pilot or ignition problems may be the cause. Whether it’s a sensor that needs cleaning or a component that needs replacing, we handle the fix safely and by the book.

Warning Signs You Need Immediate Heater Repair
Your furnace might not stop working all at once. It usually sends a few warning signs first, so noticing them early can save you from a cold night and a costly fix.
Here are some signs it’s time to give Sandium a call:
