A: Once a year, ideally in the fall before you need heat. Even in Southern California, dust builds up during the off-season, and annual service catches issues like dirty flame sensors or weak ignition parts early. Check your filter monthly during heating season.
Why Advanced? We make sure your furnace is clean, safe, and ready before the cold nights arrive.

A: Around 68°F while you’re home and awake is a good starting point, a few degrees lower while sleeping or away. With a heat pump, avoid big temperature swings, which can trigger less efficient backup heat.
Why Advanced? We can help set up a thermostat schedule that fits your system and your household.

A: First, check that the thermostat is set to HEAT, the fan is on AUTO, and the filter isn’t clogged. If those look fine, the cause may be ignition, the flame sensor, gas supply, or a safety switch, which needs a technician.
Why Advanced? We find the actual cause before recommending a repair.

A: Banging at startup often means delayed ignition from dirty burners, or ducts expanding as they heat. Whistling usually points to restricted airflow, such as a dirty filter or blocked vents. New or loud noises should be inspected.
Why Advanced? We check the furnace, airflow, and ductwork together to pinpoint the source.

A: It can be. A crack can let combustion gases, including carbon monoxide, into your home’s air, so the furnace often needs to be shut down until it’s repaired or replaced. Keep working CO detectors in your home, and if one sounds, get everyone outside and call 911.
Why Advanced? We inspect heat exchangers during furnace service and explain your options clearly.

A: Mostly blue and steady, sometimes with a small yellow tip. A yellow or orange, flickering flame can mean incomplete combustion and should be checked promptly. Don’t remove furnace panels to look; a technician can inspect it safely.
Why Advanced? We check flame and burner operation as part of every furnace tune-up.
