Most furnace manufacturers are fairly similar in terms of reliability, though some manufacturers have been consistently ranked well below the average, according to Consumer Reports.

When it comes to furnaces, there are typically two types of models, and it can be important to determine which type you have in your home.

Builder Models

These models are used by home builders and contractors to meet minimum code requirements and are typically the most inexpensive.

Retrofit Models

These furnaces provide more efficiency, more comfort, and are generally more dependable with longer warranties. A retrofit model typically lasts up to 20 years or more, when sized, installed, and maintained properly.

Reasons Why Your Furnace Might Not Be Working

Factors that affect the longevity of a gas furnace and why it may not be working include:

Wrong Size

If your furnace is too large for your home and your ductwork is not sized to accommodate the size of furnace, you may experience repeated failures.

These failures will generally include cracked or failed heat exchangers, vent motor problems, leaks, and a variety of other problems. This will typically lead to higher utility bills, decreased life, and possibly other necessary repairs.

Wrong Filters

Failure to change your filter regularly or using the improper filter can restrict the airflow to the furnace.

This will result in the furnace being clogged, and will require it to work harder to produce the same amount of heat. A furnace that has to run more often to produce the same amount of heat will result in more energy usage and higher utility bills.

Irregular Maintenance

Maintenance on your gas furnace will allow for the inspection of the unit to help determine if small adjustments need to be made.

An inspection will include:

  • Gas pressure in and out
  • Vent pressures
  • Safeties
  • Blower speeds
  • Duct pressure testing
  • Temperature rises
  • And more

This maintenance service typically takes about an hour to complete.
