Puron Refrigerant

Puron® Refrigerant is an environmentally sound refrigerant designed not to harm the earth's ozone layer. Federal law requires all manufacturers phase out ozone depleting refrigerants in the next few years. Puron Refrigerant is approved by the US Environmental Protection Agency as a replacement from R-22.

SEER (Seasonal Energy Efficiency Ratio)

SEER is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER number, the greater the efficiency–and therefore greater energy savings. Today, U.S. regulatory agencies require all new products to have a 13.0 SEER rating or better. Denmark's full line of air conditioners offers SEER ratings of up to 20.

AFUE (Annual Fuel Utilization Efficiency) information

AFUE is the standard measurement of efficiency for gas and oil-fired furnaces. Given in percentages, this number tells you how much of your fuel is used to heat your home and how much fuel is wasted. The higher the AFUE rating, the greater the efficiency. Denmark offers a full line of furnaces with AFUE ratings ranging from the minimum industry requirement of 78% to more than 96%.

Cost Savings: If you have an older furnace (with an AFUE of approximately 60%), you could save up to 40% on your heating bills by replacing it with a new high efficiency furnace! The cost to replace your old, inefficient furnace is paid back through lower utility bills.

Evolution System

A Denmark Heating And Cooling dependable Evolution® System by Bryant is the heating and cooling system of the future. Evolution is the only system you can buy from Denmark that allows you to precisely control temperature, humidity, air quality, fan speed, and ventilation—and it can even detect when your air filter needs to be replaced. Evolution is so comprehensive that it automatically adjusts to your needs for peak efficiency and performance. More on Evolution systems


  (Heating Seasonal Performance Factor)is the efficiency measurement used to gauge the efficiency of the heating mode of heat pumps. The higher the number, the greater the efficiency and cost-savings. Today's models are required to have a 6.8 HSPF. Denmark offers heat pumps with HSPF ratings ranging from 6.8 to 9.5.

Cost Savings. : Higher efficiency in heat pumps and air conditioners usually means higher equipment cost but lower utility bills. If you live in a warm and/or humid climate, you will probably see the higher cost of a high efficiency air conditioner or heat pump paid back (through lower utility bills) in a few short years. Ask Denmark to help you determine about how long it would take you to recover the additional cost in energy savings. Of course, long after the payback, you continue to save on your energy bills.

Matching Your System for Optimum Efficiency

One additional factor that affects the efficiency of your air conditioning or heat pump system is your indoor coil (also called an evaporator coil). If your condensing unit is not matched with the proper indoor coil, it may not give you the stated SEER and/or HSPF ratings and could even develop performance problems. When you replace an existing system, make sure you replace both units so your new condensing unit will give you optimal performance, efficiency and comfort.

Heat Exchanger

The part of a furnace that transfers heat to nearby air. This the main component of a gas furnace.

Perfect Light

 PERFECT LIGHT is a  silicon carbide igniter which is energized on a call for heat to light the main burner. This eliminates a constant pilot light, it is very dependable plus it saves gas thereby  saving money


The Minimum Efficiency Reporting Value is the standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter's ability remove particles from 3 to 10 microns in size.


Poor environments in houses and commercial buildings impact the health of the occupants. Most houses and buildings have dirty furnaces, ductwork, cooling coils, that have been fouled by the growth of microorganisms including viruses, bacteria, yeasts and mold. manually cleaning these is a laborious process that only temporarily removes the contaminants. Placing ultra-violet- C  (UVC) lamps designed for this purpose in the right location, will provide continuous cost effective system disinfection. This ultra violet light works by radiating to the DNA molecules of the microorganism, producing mutation, and eventually, destruction of the microbe. Thinner wall viruses are most readily destroyed followed by bacteria and then fungi.

REFRIGERANT 22  ( R- 22 )

The HCFC (hydrochloroflurocarbon) known as R-22 refrigerant will be phased out by the year 2020 in order to reduce damage to the ozone layer. The Montreal Protocol in 1987 implemented the necessary methods to ensure that HVAC manufacturers switch from using R-22 in their products to alternative, non-ozone-depleting refrigerants such as R-410A ( PURON ) or other approved refrigerants. Here are the important steps that have been initiated and are currently in progress:

2004: The Montreal Protocol required the U.S. to reduce its consumption by 35 percent below the baseline cap by the end of 2003.

2010: After 2010, chemical manufacturers may still produce R-22 to service existing equipment, but not for use in new equipment. HVAC system manufacturers will only be able to use pre-existing supplies of R-22 to produce new air conditioners and heat pumps which will be recovered from existing equipment and recycled.

2020: Use of existing refrigerant, including refrigerant that has been recovered and recycled, will be allowed beyond 2020 to service existing systems, but chemical manufacturers will no longer be able to produce R-22 to service existing air conditioners and heat pumps.

Denmark is proud to be part of this initiative to save our ozone layer. By using the ozone-friendly R-410A or other approved refrigerants instead of R-22, Denmark is taking steps to ensure eco-friendly measures and provide the best in home comfort solutions to homeowners and commercial business owners


On February 17, 2009, President Obama signed the American Recovery and Reinvestment Act of 2009 stimulus bill, which made several significant changes to the energy efficiency tax credits. Here are the major changes and how they can affect you:

      Tax credits that were previously effective for 2013 have been extended through 2014

      The tax credit has been raised from 10 to 30 percent

      The tax credits available for a specific dollar amount have been changed to 30 percent of the cost and installation

      The maximum credit has been raised from $500 to $1,500 for the year 2014. Please note that some improvements such as geothermal heat pumps, solar water heaters and solar panels are not subject to the $1,500 maximum.

Denmark continues its dedication to provide homeowners with premier products for complete home comfort. Denmark can assist you with designing a home comfort system suited to your needs.

If you are looking to take advantage of these tax credits and start improvements right away, please contact Denmark today. For a complete list of tax credits and exact requirements please visit .



Denmark Heating And Cooling would like to remind homeowners about the reinstatement of federal tax credits available on home improvements made in 2013 and 20014. Tax credits for residential products, which had expired at the end of 2012, are now available for improvements made during 2014 by way of the Economic Stabilization Act of 2008.

According to Energy Star®, replacing old heating and cooling equipment with Energy Star-rated equipment can reduce the average homeowner’s annual energy costs by $200 or more. When paired with a cumulative tax credit of 30 percent of the installed cost, up to $1,500, this creates an opportunity for homeowners to realize significant savings in 2014 and beyond.

Ultra high-efficiency products such as the new Bryant 18 SEER Condensing unit or the 17 SEER Heat Pump not only provide homeowners a tax credit, but also slash home energy consumption by improving the overall efficiency of your heating and cooling system.

Re-commissioning Building Systems

Commissioning, which simply means making sure building systems are running as designed, is an essential part of building construction, and because these systems degrade over time, they must be periodically retested. Such re-commissioning pays huge dividends, says a recent Department of Energy sponsored study: a 15 percent reduction in energy use at a cost of just 27 cents per square foot, for a payback time of less than nine months.

Commissioning entails an analysis and a tune up, and usually requires the services of an energy auditing mechanical contractor such as Denmark Heating and Cooling. Systems also have to be maintained and re-commissioned every  three to five years. Denmark Heating and Cooling can then make recommendations for improving mechanical systems performances; for example, builders usually install oversize systems even though air conditioning operates most efficiently at full power. The upside: You can probably upgrade to a smaller system that uses less energy. Today's heating and cooling and refrigerating systems are up to 40 percent more efficient than those built 20 years ago. If you cannot replace yours, if its not in the budget, improve it with a solid state variable speed motor drive that controls motors speed according to demand.

The biggest energy draw in an industrial facility is the industrial process, which also adds to the plants cooling load. Processes vary across industries, but electric motors are common to most of them, and they are an easy place in which to find energy savings. New, modern highly efficient motors are up to eight percent more efficient than the oldest motors now deployed. A solid state variable speed drive which can be attached to motors on pumps and fans is an even more powerful tool; it can increase the system's energy efficiency 50 percent, with a payback of as little as six months. These are some of the procedures Denmark Heating and Cooling can provide you with from our re-commissioning services we offer. Many of these products now qualify for government tax credits in commercial as well as industrial applications.
