Many people choose to live in Santa Rosa, California, because of its wonderful weather, which includes more than 250 sunny days per year. High temperatures in the summer typically reach the low 80s, while winter temperatures are relatively mild compared to many areas of the country.

However, that doesn’t mean Santa Rosa homeowners don’t need a reliable furnace to get them through the winter. The average low temperature in December and January is about 40 degrees – meaning a functioning furnace is a necessity.

Sometimes, it’s hard to know whether your furnace requires repairs or not. However, there are some warning signs to watch out for that can indicate a call to a heating and air conditioning company is warranted. Some of those signs include:

Rising Energy Bills

Have you noticed a sudden spike in your monthly energy bill? If so, it could be a tell-tale sign that your furnace needs to be repaired or replaced. Contact a professional HVAC company to inspect the system. If you’re heating unit is older, it may make more sense to upgrade to a new energy-efficient system. Either way, pick up the phone and call us today to request an appointment. Our phone number is 707-307-5093.

Strange Smells

Furnaces can give off a burning smell when they’re turned on for the first time each season. If the smell lingers, however, there may be an issue with the unit, and an HVAC system contractor should be called to check it out. If you smell natural gas, contact a professional immediately.

A rubber or metallic smell could mean a mechanical part, such as the blower motor, is worn out. A burning smell could be caused by an incomplete wiring connection.

Loud Noises

Aside from the sound of your furnace starting or ending a cycle, furnaces are relatively quiet appliances. If you’re hearing jarring noises such as banging, vibrating, rattling, screeching, or rumbling, something is awry, and the unit should be inspected immediately. These noises could indicate a broken or loose part.

Air Isn’t Warm Enough

If your Santa Rosa or Rohnert Park furnace is struggling mightily to keep your home warm enough during the winter, a repair is likely warranted. A furnace that isn’t producing enough warm air could be caused by a leaking duct, an electrical issue, or a faulty pilot light.

Furnace Won’t Turn On

If your furnace won’t start up at all, several issues could be at play. Some of them include a bad thermostat or one that simply needs new batteries, a tripped circuit breaker, an electrical issue within the blower compartment, a clogged drain line, or a closed gas shutoff valve.

Pilot Light Is Yellow

Your gas furnace pilot light’s flame should be a steady blue. If the flame suddenly changes color to yellow, red, or green, it could indicate the air intake valve to the pilot light is clogged with dirt, rust, or excess air. In some cases, it could also mean a carbon monoxide leak, and a professional should be contacted right away.
