FAQs
Here we’ll explore several of the most common questions about residential furnaces in Golden Valley.
Is My Furnace Cycling Correctly?
It’s important to note that furnace cycles can vary based on many factors, including how cold it is outside. A typical furnace cycle lasts between 10 and 15 minutes and should occur two or three times an hour. A furnace that turns on more frequently is short cycling, which can cause significant wear on your equipment. Furnaces that run for extended periods or long cycle typically have a thermostat-related issue.
How Often Should I Service My Furnace?
We recommend scheduling a heating tune-up at least once a year. The ideal time to schedule is in the early fall before the coldest weather arrives. Even with routine service, you should monitor for comfort and performance issues and schedule diagnostics at the earliest signs of problems. Some issues to watch for include uneven heating, irregular cycling, and low humidity levels.
Why Is My Furnace Making Loud or Unusual Noises?
Modern furnaces should be relatively silent, although you may hear some light sounds when it cycles on. If you hear a whistling sound coming through your return vents, it likely means you have a clogged filter. Squealing or grinding noises often suggest a problem with the blower, such as a worn belt or ball bearing. Popping or banging may indicate high heat rise, which can eventually lead to a cracked heat exchanger.
