In DFW, you likely have one of the following central HVAC Systems:

  • Gas Furnace & Central Air Conditioner.
  • Electric Furnace & Central Air Conditioner.
  • Electric Heat Pump with Back-Up Electric heat.  The Heat Pump also provides Air Conditioning.

If Your Home Is All Electric, A Heat Pump Benefits You

With Notably Reduced Heating Costs

  • Note: Gas furnaces are less expensive to operate than a heat pump.
  • Note: Electric furnaces are far more expensive to operate than a heat pump.  If your home is all electric, your Heat Pump Benefits are mostly lower heating costs.
  • Note: The more time a home is kept at the same temperature (70-72) — the more Heat Pump Benefits (savings)  you will realize (verus electric furnace).
  • Note: For homes where the heat is turned low and warmed up later, the electric back-up heat will turn on speed up the heating.  In this case Heat Pump Benefits (savings) are reduced
  • When the thermostat is +1 degree warmer than the indoor temperature, the heat pump provides the heating.  Heat Pump benefits are realized with this setting.
  • When the thermostat is +2 degrees warmer, the back-up electric heat turns on.   Heat Pump benefits (savings) are realized with this setting.
  • When your back-up / supplemental heat is electric, a heat pump is up to 3 times more efficient to operate.

Replacing Your All-Electric HVAC System?  You Will Get Notable Heat Pump Benefits In The Form Of Lower Heating Costs.

A Heat Pump is a more expensive to purchase up front (because they both heat & cool).  But with a Heat Pump, heating costs are reduced by up to 2/3 versus heating with an electric furnace. **

A Heat Pump provides efficient heating & cooling for your home.  This is because a heat pump moves heat rather than creating heat. A Heat Pump is an Air Conditioner that runs in reverse while heating.  In cooling-mode, it moves heat from inside your home to outdoors.  In heating-mode, it moves heat from outdoors into your home.

** Actual heat delivered for electricity used is determined by the Heat Pump’s Energy-Efficiency, expressed as HSPF (Heating Season Performance Factor).

  • A standard efficiency heat pump installed in DFW has an HSPF= 8.7 + a Cooling SEER Efficiency = 14.
  • American Standard’s most efficient Heat Pump (AccuComfort Platinum 20) provides a (heating) HSPF = 10.0 and (cooling) SEER-20.

How A Heat Pump HVAC System Works When Heating

A Heat Pump is an air conditioner that runs in reverse while heating.  In winter cold air comes out of the top of the outside unit (in summer, hot air comes out the top).  During winter, the air coming out the top is cold because the heat pump extracted the heat within the air as it passed through the outside unit.  This heats the refrigerant.  the the refrigerant is pumped into the home where a component inside the furnace (evaporator coil) moves indoor house air over the heated refrigerant,  and distributing the heat into the home.

As outside temps lower, there is less available heat within the outside air for the Heat Pump to extract.  As this occurs, back-up heat makes up the difference when the home’s heating-demand exceeds the amount of heat the Heat Pump alone can provide.

In DFW, Back-Up heat is almost always electric.  There is an electric “heat-strip” inside the furnace for heating.  As outside temperatures continue to lower, the heat strip will provide additional heat as needed.  At very cold outdoor temperatures, the Heat Pump may temporarily shut off completely (varies by Heat Pump).  If that occurs, all heat is provided by the electric heat-strip until temperatures rise again.

 Your Home’s Fuel & Power Options Are The Deciding Factor When Selecting An HVAC System

In DFW, Natural Gas Heat Is Less Expensive Than Using A Heat Pump

In DFW, nearly all homes have furnaces that are either (natural) gas or electric.  Most homes connected to natural gas have a gas furnace.  If your home is all electric, and gas lines pass are near your home, you may be able to connect your home and convert to natural gas heat.  This can be a detailed and expensive upgrade however.   Based on the annual heating costs shown below, adding natural gas to your home is likely cost-prohibitive given in light of being able to reduce your (electric heat) heating costs by 1/3 or more with a Heat Pump.

Heat Pumps require the same electrical power as central a/c.  No new electrical line is not required (if you currently have central a/c & electric furnace).  If your home is all electric, a Heat Pump Benefits come in the form of tremendous savings over electric heat.  If your DFW home has natural gas,  the cost of heating your home with gas (80% standard-efficiency furnace) is lower (about 2/3 the cost of operating an electric Heat Pump with electric back-up heat).  For homes with natural gas, purchase a traditional gas furnace and central air conditioner.

The #1 Heat Pump Problem Is Caused By Setting The Thermostat Wrong

Resulting In Much Higher Heating Bills

  • With a Heat Pump HVAC System, the Heat setting activates supplemental / back-up heat only if the Heat Pump can’t keep up (due to low outdoor temps).  
  • “Emergency Heat” Setting is used only if the Heat Pump quits working. 
  • The “Emergency Heat” setting turns the heat pump off.  Then all heat is created by the electric heat-strip (inside the furnace) and no Heat Pump benefits exist.
  • Heat strips are 2-3 times more expensive to operate than Heat Pumps.

NOTE: With your thermostat correctly set to “HEAT” — check to be sure the outside unit is running when the furnace blower is running.  If the outside unit is not operating, the back-up electric heat will automatically come on, and you won’t know the outside unit is not running because the house is warm.  When the outside unit is not running, the cost to heat your home is the same as an electric furnace (because the electric back-up heat is provide all heat).

 

American Standard & Trane Climatuff® Heat Pump & A/C Compressors

  • Since the 1930’s Trane / American Standard Has Made Their Own Residential A/C  Compressors.
  • Trane manufactured their first Heat Pump Compressor in 1964.
  • Today they continue make both Reciprocating (piston) and Scroll (rotating) compressors.

During Defrosting, American Standard & Trane Heat Pumps operate notably more quietly than nearly all other brands because of the compressor.  American Standard & Trane Heat Pumps and Air Conditioners have their proprietary design Climatuff® compressor.  Nearly all other residential heat pump brands have a Copeland (brand) compressor. Copeland Heat Pump compressors operate at a higher noise-level during a Defrost-Cycle.

American Standard & Trane Climatuff® Compressors Have A

History Of Long Lifespans

Here is an interesting & entertaining story (taken from their website) about “SnowBall I” & “Snowball II” Climatuff® Compressors located at Trane’s Tyler, TX testing facility.

The original Snowball I Climatuff® compressor lasted from late 1972 until 2000, running nearly 28 years!  It ran at an estimated 3,500 rpm, equaling an automobile running 60-70 miles per hour and covering 14.8 million miles!  Five presidents later, and seeing the rise and fall of: disco, glam rock and grunge music, Snowball I finally ran out of steam.  It left a legacy in the name of the patented Climatuff® compressor

Snowball II has lived at the Compressor Test Lab in Tyler, Texas since 2000. This is the test lab where this durable Climatuff® compressor is constantly running, enduring extreme heat and cold, working tirelessly at high pressure levels.
