Heating and Furnace FAQs
Why does my furnace smell like it is burning when I first turn it on?
A burning dust smell is common the first time you turn on your heater for the winter, as accumulated dust burns off the heat exchanger. However, if the smell persists for more than a few hours, or if it smells like electrical burning or gas, turn the system off immediately and call for professional service.
What is the difference between a furnace and a heat pump?
A furnace generates heat by burning fuel (like natural gas) or using electric resistance. A heat pump, on the other hand, does not generate heat; it extracts ambient heat from the outside air and moves it inside. Heat pumps are highly efficient and can also reverse operation to act as an air conditioner in the summer.
How often should I change my furnace filter?
For most homes in Southern California, we recommend changing your standard 1-inch furnace filter every 30 to 90 days. If you have pets, suffer from allergies, or have experienced a lot of dust from local wildfires, you should check and replace it more frequently.
Why is my gas furnace blowing cold air?
This can happen for several reasons, including a dirty air filter restricting airflow, an unlit pilot light, a faulty thermocouple, or an issue with the gas supply. Our technicians can quickly diagnose the exact cause.
Is a yellow pilot light dangerous?
Yes. A healthy gas furnace pilot light should be a crisp blue color. A yellow or orange flame indicates that the gas is not burning cleanly and completely, which can produce dangerous carbon monoxide. Call a professional immediately if you notice this.
How long does a typical furnace last?
With annual preventative maintenance, a standard gas furnace can last 15 to 20 years. Electric furnaces and heat pumps typically have a similar lifespan when properly cared for.
