Common Heating Problems in the Winter


As the temperature has dropped at this time of year, people are starting to use the heater to keep their houses warm and comfortable.  Unfortunately, many people find that they have problems when using their heater for the first time in the winter season. Fortunately, many issues are predictable and easy to solve.


Here is our list of the top five common heating problems you may face this winter:

  1. Flame Sensor Problems

A flame sensor ensures the system has ignited and makes sure the gas keeps flowing properly. Having this sensor malfunction is a major safety hazard. Signs of a bad flame sensor are if your furnace short cycles, the porcelain is cracked, or the sensor is corroded.

  1. Carbon Monoxide

Carbon monoxide is colorless, odorless, and tasteless, but it is a potentially deadly gas. In rare cases, a problem with your heating system could cause carbon monoxide to build up to dangerous levels in your home. Every home should have a carbon monoxide detector installed to combat this problem. Also, you should have your heating system inspected by a professional at least once a year.

  1. The Heater is Blowing Cold Air

Sometimes, your heater may blow out cold air. If this happens to you, check your thermostat first to make sure it’s set at the correct temperature and operating mode.

  1. Turning on and Off

Does your heater turn on and off too often? This phenomenon is known as heat cycling. Heat cycling reduces the efficiency of your system and increases your utility bill. Oftentimes, heat cycling is caused by minor issues like a malfunctioning thermostat or a clogged filter. A heating professional can diagnose and repair this problem quickly.

  1. Inconsistent Temperatures

Ideally, your heater will maintain a comfortable temperature throughout your house. However, this doesn’t always happen. One room might be too warm while walking into another might feel like stepping into the freezer. There are many potential causes for inconsistent temperatures, including poor insulation, clogged ductwork, or even a heater register that someone accidentally closed. If you have erratic temperatures throughout your home and don’t know why call a heating professional.


As the temperature drops, we ask our heater to do the job of keeping our house warm and comfortable. However, if you’ve neglected regular maintenance on your system, it may not be there for you when you need it. Don’t let this happen to you. Be sure to perform all your regular maintenance, such as changing your filters, and schedule a routine inspection by a heating professional.
