Christopher Montana,

of Environmental North Carolina Inc.

(EHA-NC), Cary, NC, parlayed green HVACR

certification into a cohesive marketing effort.

Some contractors are going deep into the green market, and it’s serving them well.  It’s not just following a trend; it’s offering real value to customers.  That’s why it works.

For instance, alternative energy retailing, green-oriented HVAC service contracting, and developing and marketing its own solar-assisted heat pump are just a few of the things that helped form Environmental Heating & Air of North Carolina Inc. (EHA-NC) last year.

Vice presidents green HVACR certification tied those building block philosophies into a cohesive marketing effort.  “We already had great ideas, knowledge, and products, but the certification really gave us the credibility and the marketing tools needed to market ourselves as green,” explained company president Christopher Montana.

Profitt earned his “Green HVACR Certification” by downloading an 85-page desktop manual, Green HVACR Technician Certification: A Desktop Reference & Training Guide for Implementing Green Practices in Building Thermal Control in Residential/Commercial/Industrial Refrigeration, from  The manual was written by Robert P. Scaringe, P.E., Ph.D., and president of Mainstream Engineering.  The manual was free, although Profitt paid $24.95 for the subsequent online testing and certification.


Montana, a commercial real estate investor, and Staff, a 10-year commercial-residential HVACR service tech veteran, said they formed EHA-NC because few contractors were advocating and promoting green HVAC system installation, retrofit, and service work within a targeted 100-mile geographical radius of their headquarters.

HVACR contractors offering solar heating-power, wind power, LED lighting, grid-tie inverters, and other alternative energy technologies are still relatively uncommon. Through research, the duo also learned that many of the Raleigh, NC, suburb’s 132,000 residents are receptive to green technology because they’re employed at nearby Research Triangle Park.

“Many HVACR contractor services are already green,” said Profitt, “such as cleaning coils, changing filters, and making efficiency improvements, but contractors don’t realize the potential in promoting these services as green.” Profitt will also be mandating the green training-certification for EHC’s six service techs and installers. “The certification provided us with truck decals, arm patches, and other ideas on promoting green.”

The contractor promotes its green message in weekly 60-second radio advertisements, monthly magazines such as Cary Monthly, weekly newspapers such as the Coffee News, and direct mail. The contractor also takes advantage of other green opportunities such as the local utility, Progress Energy’s “Home Energy Improvement Program” (HEIP), which requires an educational class for participation. “HEIP and our Green HVACR Certification complement each other nicely,” .

RETAIL Sales on High House Road Cary North Carolina

A truck for Environmental Heating & Air of North Carolina Inc. The company offers environmentally conscientious products and services to customers who can’t get them locally.

The contractor also has opened Alt Energy Country, a 1,400-square-foot retail store adjacent to its office and contracting headquarters. This highly visible cornerstone showcases the company’s green mission.

Displays of Carrier and York high-SEER HVAC equipment offer visual demonstrations of potential energy savings. Other equipment demonstrations include solar panels, photovoltaic cells, LED tube lighting retrofit kits for fluorescent fixtures, cyclonic-evacuated tube manifolds for domestic hot water heating, wind generators, voltage regulators, water boost heat systems, controller panels, transfer tanks, heat exchange manifolds, grid-tie inverters, etc.

A majority of the SKUs carried in the store are private labeled under the Alt Energy Country brand. One of the store’s main goals will be promoting the solar-assisted, split system heat pump Profitt and Montana designed to sell to their customer base, as well as to HVAC contractors around the nation. The patent-pending, self-contained, 2-ton model marketed and distributed under the Alt Energy Country brand is unique for the U.S. market; it uses cyclonic evacuated-tube technology to provide an approximate 10 percent energy boost.

The system currently heats and cools the EHA-NC offices for a monthly average of $99 (versus a conventional heat pump in a next-door office with identical square footages and similar heat loads, operating at $150/month). The solar-assisted heat pump costs approximately 40 percent more than a mini-split, but the payback in energy savings is less than two years, according to Montana.

“The solar-assisted heat pump puts out much hotter and cooler temperatures while using considerably less energy,” he said, “and the payback is very short because cyclonic-evacuated tube technology has become very affordable.”

While the solar-assisted heat pump is only available as a 2-ton model, Alt Energy Country also has a retrofit model for heating only and an upcoming heating-cooling retrofit model that will be compatible with most sizes of conventional residential heat pumps, the company said. “People shouldn’t have to change out perfectly fine equipment before its lifecycle ends,” Montana said; “therefore we’re strong believers in retrofit products.”

The success of Alt Energy Country and the firm’s existing and future product developments depends on the public’s continued progression toward energy and environmental consciousness. “The behavior of people here in America is becoming more value oriented and long-term minded,” said Montana. “I think offering people a product that is affordable upfront, that saves a significant amount of energy versus conventional equipment, and that can help make the world a cleaner place for their children, will encourage them to buy into it.”

Originally, the Residential Renewable Energy Tax Credit enacted in 2005, only offered tax credits for solar electric systems, solar water heating, and fuel cells. The Energy Improvement and Extension Act of 2008 expanded the tax credit to include geothermal heat pumps.

Though the act was passed recently, tax credits are retroactive to Jan. 1, 2008, and expire Jan, 31, 2016. Homeowners may claim a 30% credit on qualified expenditures for a system that services a dwelling located in the U.S. and used as a residence by the taxpayer. The maximum incentive is $2,000. The home served by the system does not have to be the taxpayers’ principal residence. Expenditures include labor costs for on-site preparation, assembly or original system installation, and for piping or wiring to connect a system to the home.

The geothermal heat pump unit must meet the requirements of the Energy Star program in effect at the time the installation is completed. The act also eliminates the solar-electric credit cap effective Jan. 1, 2009.





When a customer in the greater Raleigh/Durham metro area wants to install a geothermal heating and air unit, we get excited because they have decided to take the next step towards a greener America!  We are fond of this product because of its high energy efficiency rating, 26 - 28, which is a very high rating for today’s energy soaking appliances.


Geothermal heating & air systems are expensive and they address only one portion of your energy needs, which is heat and air.  Enviro NC sees this with a different perspective than most.  Enviro NC often times will wind up recommending, with certainty, the needs of the customer will be better served if they purchase a solar PV panel array with a grid tie inverter, which will address all of the energy needs of one's property.  The cost is very similar to a geothermal, but a PV solar array grid tied with net metering will give you the opportunity to sell back excess power to the power company.  The tax credits for these systems are fantastic right now and will probably continue to be for the foreseeable future.


Being knowledgeable and forward thinking is what makes Enviro NC standout head and shoulders above the competitors.  Give us a call and we can help you decide if this 'green' step is right for you.  We are located in Cary, about 5-10 minutes from Raleigh and about 20 minutes from Durham.  We would be glad to set up an appointment to discuss energy needs and what's right for you.

Heat Pump Systems

For climates with moderate heating and cooling needs, heat pumps offer a more energy-efficient alternative to furnaces and air conditioners.  Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, making the cool space cooler and the warm space warmer.  During the heating season, heat pumps move heat from the cool outdoors into your warm house; during the cooling season, heat pumps move heat from your cool house into the warm outdoors.  Because they move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume.

The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air. If you heat with electricity, a heat pump can trim the amount of electricity you use for heating by as much as 30%–40%.  High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.  However, the efficiency of most air-source heat pumps as a heat source drops dramatically at low temperatures, generally making them unsuitable for cold climates, although there are systems that can overcome that problem.

For homes without ducts, air-source heat pumps are also available in a ductless version called a mini-split heat pump.  In addition, a special type of air-source heat pump called a "reverse cycle chiller" generates hot and cold water rather than air, allowing it to be used with radiant floor heating systems in heating mode.

Higher efficiencies are achieved with geothermal (ground-source or water-source) heat pumps, which transfer heat between your house and the ground or a nearby water source.  Although they cost more to install, geothermal heat pumps have low operating costs because they take advantage of relatively constant ground or water temperatures.  However, the installation depends on the size of your lot, the subsoil and landscape.  Ground-source or water-source heat pumps can be used in more extreme climate conditions than air-source heat pumps, and customer satisfaction with the systems is very high.

A new type of heat pump for residential systems is the absorption heat pump, also called a gas-fired heat pump.  Absorption heat pumps use heat as their energy source, and can be driven with a wide variety of heat sources.

For more information on these specific types of heat pumps, see these sections:



U.S. households rely primarily on three sources of energy: natural gas, electricity, and fuel oil. In the past several decades electricity’s share of household consumption has grown dramatically, and the shares of natural gas and fuel oil have declined. Retail sales of electricity to U.S. households exceeds sales of electricity to the commercial and industrial sectors.

This report is based on data from EIA's Residential Energy Consumption Survey. The report presents a snapshot of national household electricity consumption in 2001. It is the first in a series of reports analyzing data on electricity end uses, including air-conditioning, space heating, water heating, lighting, and appliance operation (Figure US-1). Statistics on annual energy consumption by over two dozen individual appliances are included (Table US-1).


Electricity consumption by 107 million U.S. households in 2001 totaled 1,140 billion kWh. The most significant end uses were central air-conditioning and refrigerators, each of which accounted for about 14 percent of the U.S. total.

HVAC and Water

This industry, and cooling (HVAC) accounted for 356 billion kWh, 31 percent of the electricity consumed by U.S. households in 2001. Central air-conditioning alone accounted for almost half of the HVAC total (Figure US-2). Although there were improvements in the efficiency of the U.S. stock of air-conditioners over time, central air-conditioning continued to be responsible for the greatest share of household electricity use. The predominance of air-conditioning was due to a significant increase in the number of households with central air-conditioning in the two decades preceding 2001. The share of households with central air-conditioning rose from 27 percent of households in 1980 to 55 percent in 2001.

Electric space heating accounted for an additional 116 billion kWh (10 percent of the total), which is considerable given that, nationwide, space heating was predominantly fueled by natural gas. In almost 31 million households, electricity was the source of energy for the main heating system. In an additional 13 million households, it was used in secondary heating equipment, such as portable heaters and built-in electric units.

Electric furnace fans, which are components of natural gas, fuel oil, and liquefied petroleum gas (LPG) furnaces, as well as electric furnaces, were used in 76 million households and consumed 38 billion kWh of electricity (3 percent). Other HVAC-related appliances—ceiling fans, dehumidifiers, humidifiers, and evaporator coolers—all together accounted for less than 2 percent of U.S. electricity consumption in 2001.

Electric water elements accounted for over 100 billion kWh (9 percent) in 2001. Of the total of 107 million households, 41 million used electricity as their water fuel, compared with 58 million households that used natural gas.

Renovations.... Here is a very Easy Option

Call our sales department and ask for a estimate on either a Mini Split which in general will handle a larger single space addition. Good examples for this Attic space bonus rooms and enclosed porches in back of ones house. Very energy efficient product. But can lend itself to being a bit more extensive with layout and install time on job.

The second and one that hotels use all the time is the in wall Ptac. We have some really quiet ones and they are so easy to put in. Much Cheaper than a Mini Split system. They both come in Heat Pump or just air conditioning cooling. Your Choice. Efficiency is not as flexible with the Ptac BUT are you going to use it enough to save the difference in money, you must ask yourself that. Have a look and call us at environmental heating & air plus Plumbing.
