As residents of the sunny state of California, we’re no strangers to the occasional cold snap. When the temperature drops, a well-functioning furnace isn’t just a luxury—it’s a necessity. But what do you do when your trusty furnace decides to take a break? Worry not! At California A/C & Heating, we’ve got your back. Let’s explore some common furnace issues and how to address them.

1. Is Your Furnace Playing Hide and Seek with Power?

First things first, check if your furnace is actually turned on. It sounds simple, but the power switch, often overlooked during the warm months, might be off. A quick flip could be the easy fix you need!

2. Circuit Breaker Conundrums

Just like us, furnaces can get overwhelmed. A tripped circuit breaker is often a culprit behind a non-responsive furnace. However, if your furnace is a regular at the circuit breaker, it’s time to call in the pros from California A/C & Heating for a deeper look.

3. Overheating: A Hot Issue

Furnaces, like any machine, can overheat. Safety mechanisms are there to shut it down if things get too heated. Continuously running an overheating furnace isn’t just bad for the system—it’s unsafe.

4. Safety Mechanisms: Too Safe for Comfort?

Speaking of safety, furnaces are equipped with various mechanisms like limit switches and flame sensors. While these are vital for safety, they can malfunction, leaving you in the cold. Regular maintenance can keep these guardians in check.

5. Electric Furnace Follies: The Sequencer Saga

For those with electric furnaces, a failed sequencer can be the troublemaker. This component manages the heating elements, and when it fails, it’s like a conductor losing their baton—the orchestra just doesn’t play.

6. Gas Line Grief

Gas furnaces rely on a steady supply of fuel. Issues like a stuck valve or buildup in the line can halt your furnace’s performance. Remember, gas line problems are not DIY friendly—safety first!

7. Thermostat Troubles

Sometimes, the issue isn’t with the furnace but the thermostat. Loose wires, miscalibration, or complete failure can all prevent your furnace from kicking in. Regular checks can save you from these sneaky issues.

8. The Final Curtain: Full Breakdown

All things have a lifespan, and your furnace is no exception. If your furnace is over 15 years old and starts failing, it might be time to bid farewell and welcome a newer, more efficient model.
