What Size Furnace Do I Need?

Before you purchase a new furnace, one of our certified technicians will perform a heating load calculation to determine the correct sizing of your new equipment. This calculation is based on a number of factors, including the size of the home, the number of occupants, insulation levels, and more. A furnace that is too large will short-cycle, continuously turning off and on as it quickly reaches the desired temperature in the home, while one that is too small will struggle to maintain the setpoint on your thermostat. Improper sizing creates unnecessary wear and tear on parts and can lead to a shortened life span for the furnace and unusually high energy bills for you.

Advantages of Replacing an Older Furnace

With an average life span of 12 to 15 years, you may start to notice a decrease in efficiency around the 10-year mark. Replacing your older furnace with a new, energy-efficient unit comes with a number of benefits, including:

  • Reduced energy usage
  • Fewer repairs
  • Warranty coverage
  • Enhanced reliability
  • Greater comfort

Ductless Furnaces

Ductless heating and cooling is the perfect solution in areas or rooms where no ductwork is present. It consists of an outdoor unit and one or more wall- or ceiling-mounted indoor units, connected through a small, three-inch hole in the exterior wall. Each indoor unit is individually and remotely controlled for unsurpassed temperature control, comfort, and energy efficiency. We install ductless furnaces in Fremont, California, and throughout the entire Bay Area.

Frequently Asked Questions

What types of furnaces are there?

Furnaces are divided into categories based on fuel type, including:

How often should I change my furnace filter?

Clean or replace your furnace filter once every four to six weeks during peak heating season.

What is a MERV rating?

MERV stands for Minimum Efficiency Reporting Value, with a rating from 1-16. The higher the MERV rating, the more efficient the filter is at trapping minute particles. Most residential furnaces utilize filters with a rating between 8-13.

How do I know whether to repair or replace my furnace?

If your furnace is greater than 10 years old, you are facing a repair greater than 50% of the cost of replacement, or your home lacks comfort, you should consider replacing your existing furnace with a new, ENERGY STAR rated appliance.
