New Heat Pump, NRG System or Both?

Powerful, quiet and efficient. If you have found this site you are ready to make a very important decision affecting:

  • Rising APS & SRP bills for years to come
  • Your comfort every month
  • Indoor air quality
  • Duct losses
  • Reliability and Repair Cost
  • Increased Home Value
  • How long your new heat pump will last
  • How long your existing roof will last (cooler roofs last longer)

Our focus is not just selling you a new heat pump, but the reduction of energy and comfort in your home. Since our focus is your comfort, energy bills and indoor air quality, there is much more to consider than just changing out the heat pump.

We have been refining our NRG System® since 1981 and can apply what we have learned to your home.

Rather than give away this knowledge to our competitors, we prefer to meet with you at your home, define your specific needs, identify the existing problems and offer cost effective solutions. Digital photos are taken and archived in our growing library inspections. Below is a photographic representation of the heat pump change. Best to start with an in home energy audit.

Email us with your contact info so we can schedule your appointment and show you how we can help you save energy, double the life of your new heat pump, lower your carbon footprint and improve your indoor air quality.


Split system (ground mounted condensing unit) residential: Your existing HVAC system has R-22 DO NOT want to "upgrade" to the new R-410a refrigerant. Even though the SEER rating may be higher, it will consume more energy during hot summer days than R-22. Further, you DO NOT need to change the entire system, only the condensing unit. We reburbish the air handler so it will last another 15 years. We've fielded numerous calls over the last two years (since the introduction of R410a), and the comments are the same: "My electric bill went up not down". R-22 runs at a lower head pressure and thus is more efficient.

Roof mounted units: Have your new unit installed in a downdraft configuration (see below), for maximum efficiency.

If you have a roof mounted unit this is how your heat pump probably looks right now. Notice the sheet metal elbow on the back? This type of installation is prone to air and water leaks, gets hot from the sun, is not efficient and is lined with fiberglass which puts fibers into the air your family is breathing. While the unit is off, this elbow becomes a solar oven and every time the unit starts up, this superheated air is blown into your home wasting money, causing longer run cycles, increasing your APS or SRP bills and puts dust and fiberglass into the air. Further, once the elbow is installed, the evaporator coil cannot be cleaned without cutting holes in the side of the elbow. This is especially important if you have any pets.

Rooftop mounted heat pumps like this are on many homes in Phoenix with the popular duct elbow attached at the rear. Lined only with 1" of duct insulation it becomes a solar oven as soon as the sun comes up. Every time the thermostat calls for cooling the hot, stagnant, superheated air comes pouring into the house along with the fiberglass that is lining the duct. Since it is upstream of the air filter, these fibers are blown continuously through the duct system from the day it's installed. Fiberglass was identified by the EPA to be a known carcinogen, read the warning label on a Pink Panther bag next time you are in Home Depot. Click here for more information on elbows.


First, we remove the duct elbow. All the air that exits from your grills must pass through this elbow which is not filtered and is then delivered into your home. Further, there is no way to access this area once the elbow is installed to clean it unless the unit is removed or a large access hole is cut into the side (very common). Further, Roof elbows are notorious for being a major source of energy wasting air leaks which reduces the performance of the heat pump. Eliminating this elbow has many benefits but is more work and more costly. Anything done right the first time typically has a higher cost.

Once the elbow is off we can remove the existing supply and return ducting between the roof and the main ducts below. Through experience we have found this ducting to be a source of air leaks and in most cases, uninsulated. The existing ducting you see here is completely removed and replaced with energy efficient, clean flex duct which is sealed at the bottom and at the top of the new adjustable roof stand.

These are the new insulated, efficient supply and return ducts that replaces what you have now. In homes, the original ducts are not of sufficient size to adequately move the air and typically we upsize these to insure you new heat pump will be operating at maximum efficiency (done right the second time). The highly reflective outer duct cover you see here is very resistant to the infrared heat found in Arizona attics. We also wrap these and all exposed ducts with our patented Thermal Control Membrane . This means while the unit is off the air inside the ducting stays cooler in the summer and warmer during cold winter nights thus making the entire system more efficient. Most companies replacing heat pumps do not address these ducts and only change the elbow on the roof and add the new heat pump. Most every a/c company changing a heat pump ignores existing duct leaks and problems in the attic are typically not addressed as it's more work, more parts and less profit.

This shows the new ducting sealed into the adjustable roof stand. Waterproof, no fiberglass to breath, new larger supply and return ducts and no leaks. This design increases overall efficiency, delivers colder, cleaner air. What you see here at the left is a galvanized steel, high quality adjustable roof jack this is less likely to leak water and does not allow room below the unit for pigeons to make nests. One important benefit of this type of installation is the ability for the installer to visually inspect the mating of the unit to the jack when the crane lowers it onto the roof.

ZERO duct leakage is now possible with this type of installation if done correctly.

Other valley HVAC companies that do offer a down draft configuration opt for a less expensive steel stand combined with a duct drop as seen here.

This is not as efficient as our full down draft jack, is a haven for pigeons and more prone to water leaks.

This custom fabricated adjustable down draft roof curb securely mounts the new heat pump to the roof. The ducts are below and insulated from the hot sun. The wide flange and inside drip guards means it will never leak water (never had one leak yet)

Being enclosed prevents unwanted pests from nesting or living under the unit.


Before: inefficient 30 year old unit, leaky elbow, exposed wiring (2.5 ton Gas Pack)

After: Down draft install is efficient, healthy and quiet. Why would you want it installed any other way?


"Why don't other companies install heat pumps like this?"
It costs more and requires additional labor to install which means less profit. Why put an efficient new heat pump or a/c unit on a leaking, fiberglass lined elbow which turns into a solar oven everytime the unit turns off.

"Does it take longer to install than other systems?"
Yes, but doing anything right the first time typically requires more time and expense. Typically the total change out is done with two man crew starting at 6 am and turning on the new unit at noon depending on the condition of the existing ductwork.

"Is all the ductwork changed in the attic?"
If need be yes. If not, the existing ducts if sized and installed correctly are then wrapped in our patented TCM Duct Wrap product for increased efficiency, less duct losses and shorter unit run times. On most every home we find undersized supply and return ducts which are increased in size during our installation procedure. This is important in older homes as the increased velocity from the down draft configuration delivers more air.

"What else is included in the installation?"
All ducts joints are checked for leaks and sealed if needed a new service disconnect is installed with each system return grill is checked for noise (new units move much more air) balancing of air ducts to ensure maximum performance check utility rate and suggest options removal of existing equipment commitment to doing the job right the first time.

"Do I need more attic venting?"
Attic venting in most homes we have inspected in the valley are grossly under vented and are solar ovens. This greatly reduces the overall efficiency of your new heat pump, increases the load and decreases the life of the unit. Our venting web site illustrates what we have found in homes like yours and what we have developed to overcome existing anomalies.

"What does it cost?"
All the pricing for new heat pumps are listed below. Order your change out online and pay no sales commissions! We will send out an installer to inspect your home to obtain pertinent data and insure a smooth and safe installation.

Given the choice, wouldn't you want the most efficient installation? Most people would but are not given the option.
