Why Winter HVAC Strain Can Be Such a Problem for Your Unit

Winter puts extra strain on all of us, and your HVAC system is no exception. If you’re not careful, seemingly minor problems can overwork your system. The result is high energy bills, frequent breakdowns, and a shortened life span for your furnace. Here are some of the leading causes of winter HVAC strain and how to prevent them.

  • Clogged air filter. When you seal your house against the cold, winter air, all the dust and contaminants in your indoor air tend to linger, cycling through your system over and over and clogging your filter more quickly. A clogged filter means less airflow, which in turn means your system has to work harder to heat your home properly. Check your filter regularly and change 1″ filters every month and specialty filters should be checked every three months to prevent clogging and eventual winter HVAC strain.
  • Motor burnout. As your furnace gets older, a heavy heating load can cause strain on the motor. Eventually, the motor burns out and the blower shuts off. To prevent this, don’t neglect your annual furnace maintenance at the beginning of each heating season. Your HVAC technician will make sure the motor is properly lubricated, clean out any dust or debris from inside the system, replace any parts that are on the verge of failing, and ensure your system runs at peak efficiency.
  • Faulty ignition. Potentially hazardous-gas pilot lights have been replaced by electric ignition systems in most modern furnaces. However, problems with the unit’s electrical system can stop the ignition from working properly and prevent your furnace from turning on. Call your HVAC technician to fix the problem.
  • Thermostat issues. Sometimes winter HVAC strain is caused by your thermostat. If it’s not calibrated properly or has the wrong setting, it can result in short-cycling, where the system repeatedly turns itself on and off. You may also experience uneven heating or no heat at all, as well as abnormally high energy bills. To prevent this, call your HVAC technician to calibrate your thermostat and make sure it’s working properly.
