If you are buying or building a new house right now, STOP. If you are replacing your old heating system right now, STOP. Donít make another move until you hear what I have to say.

I want to tell you about one of the best kept secrets of all times - a way you can heat your home with about 30% of what you are currently spending. You can heat your water for little or no extra cost. You can melt snow, ice, and heat your pool water.

All you need to do is collect the free energy from the sun. Thatís all!

Iím not talking about big bulky solar panels attached to your roof. The answer to the secret is right under your feet. The ground has always collected the energy from the sun.  This free energy source will heat or cool your home without burning any fossil fuel. That means NO gas bill and lower power bills.

I am talking about a Geothermal Heat Pump (GHP). Now you need to hear the rest of the story.

Depending on factors such as climate, soil conditions, the system features you choose, and available financing and incentives, you may recoup your initial investment in two to ten years through lower utility bills. And -- when included in a mortgage -- your investment in a GHP will produce a positive cash flow from the beginning. For example, if the extra $3,500 cost of the GHP will add $20 to $30 per month to each mortgage payment, the energy cost savings alone will easily exceed that added mortgage amount over the course of each year. It may also be possible to include the purchase of a GHP system in an "energy-efficient mortgage" that would cover this and other energy-saving improvements to the home.

There are also other incentives available such as tax credits for geothermal heat pumps and geothermal equipment that uses geothermal energy for water heating or active space heating or cooling used for a non-business purpose:

Federal Tax Credit of 30% of cost with no upper limit.

North Carolina Tax Credit of 35% of cost up to $8,400.

                                                                Energy Waste


The new 2012 energy conservation code has finally addressed the real problem with energy loss in a heating and cooling system. Itís not enough to raise the seer rating on heat pumps and air conditioning units. Replacing your old unit with a new efficient unit WILL NOT SAVE ENERGY OR MONEY with a leaking or poorly insulated duct system.

 Recent research funded by DOE and CIEE through LBNL has therefore concentrated on forced air distribution systems and found that typically a quarter of the energy (and therefore money) used for heating and cooling is wasted through duct system energy losses.

 Problem #1

 Most HVAC Duct Systems are installed in attics, crawlspaces, garages, basements and other locations outside the conditioned space and in contact with the outside air. If the ducts are not insulated properly they will loose and gain heat from the outside by heat conduction. (= lost energy and money)

 Problem #2

 Air Leaks are a common problem with most duct systems. Conditioned air to heat or cool your home is now leaking to the outside. Even worse your system could be pulling outside air into your home from the attic or crawlspace. Now you have more air to condition that your system was not designed for. (= lost energy and money)

 Problem #3

 Load calculation and duct design are the most important parts of a system. If a system is not designed properly, the units could be over or under-sized, wasting energy and money.

A poor system design will cause uneven temperatures and reduce the comfort of your home. Each room of your home has special needs depending on size, windows and doors, outside walls, and the direction the outside wall faces (north, south, east, and west). If the supply and return ducts are not sized correctly, your system could actually cause a negative or positive pressure in a room forcing air in or out of air leaks around doors and windows. (= lost energy and money)


Todayís code changes have solved these problems.



 In most areas R-8 Insulation is required on all ductwork.

 All duct joints, seams, terminations and connections have to be sealed with approved tape or mastic.

 All new construction and existing homes have to have a load calculation to determine the proper size of equipment.

 All new construction duct systems have to be tested for leakage by a certified technician.


Davie Heating & Air Conditioning Inc. welcomes the new codes and we are proud to say that we have performed a load calculation on every house we install a new system in.

 We always insulate ALL ductwork we install.

 We always seal all duct systems, even around floor registers before it was code.

 We test duct systems for leaks to make sure you get all the conditioned air you pay for.


Always use a licensed contractor with certified technicians and always obtain permits. If you donít, the codes mean nothing because there is no one to be held accountable.
