BTUs = Heat

Heat output is rated in BTUs. Heat Pump BTUs are calculated by Tonnage x 12,000, so a 3 ton unit will make about 36,000 BTUs. To compare, the typical furnace installed with a 3 ton A/C systems would be about 100,000 BTUs.  This translates into two to three times faster heating.

Gas Furnace vs Heat Pump

For a Clearwater (Tampa Bay) area home

Heat Pumps

  • Heats without drying the air
  • No Harmful combustion gasses
  • More Energy Efficient then gas
  • A/C system not idle in winter
  • 40s and below has trouble making heat
  • Blowing air can feel cold during defrost cycles
  • Supliments with expensive electric heat

Gas Furnace

  • Makes powerful heat regardless of outdoor temp
  • Can quickly warm cool spaces (see BTUs = Heat)
  • Quiet – no outdoor unit running during heat
  • Heat cycles may keep the cooling coil cleaner
  • Deadly carbon monoxide must be monitored
  • Can make the air and your skin very dry
  • Cost of fuel more expensive per BTU

The Truth

Information about gas furnace efficiency and our area.


Furnaces group into two efficiencies: 90% and 80%.  The 90% are a condensing style furnace which require special combustion air venting. Retrofitting to a 90% can be quite expensive. The base cost of 90% furnaces cost about 25-30% more than an 80%.  An additional cost is involved in retrofitting to accommodate a 90% when an 80% has been removed. If your home does not have natural gas currently, it can be a considerable expense to have that service installed. In a northern area with a long winter, the extra expence will eventually pay for itself in savings, in our area customers be confident in knowing they have a smaller carbon footprint. As a consumer, it is up to you to best decide how to heat and cool your home.
