Home Environment Systems.

"HVAC," (the acronym stands for Heating, Ventilation and Air Conditioning) is frequently used to describe home heating and cooling systems. HVAC are the 3 primary functions of a home system. They are the critical aspect of comfortable indoor living are heating and cooling. They are often the two major factors for those looking to purchase homes.

Central Heating and Cooling Systems

A central heating and cooling system produces warm or cool air in one central area and then distributes it throughout the home. There are many types of systems that work as central systems, from traditional split systems to packaged product systems.

Products typically used in central heating and cooling systems include:


Heating systems keep your home warm and comfortable. If you live in a particularly cold climate, the function of your heating system is a high priority.

Most central heating and cooling systems are classified as forced air systems, because they send air through ductwork for distribution. The ductwork can contain products that filter or clean the air.

Radiant systems create heat and deliver it via components such as radiators that radiate the heat into the home.

Typical heating products include:

Model 310 Multi-Poise - For a perfect fit in nearly any home, the Model 310 gas furnace delivers quality comfort from a compact cabinet just 33 1/3” tall. To ensure maximum versatility, it can be installed in all four standard positions with 13 available vent configurations, easily adapting to the most challenging installation.

Model 340AAV - The patented secondary heat exchanger helps to transfer an additional 11 – 15% of the available heat into your home for money savings, energy efficiency and comfort. Model 353BAV Provides the soothing warmth of gas heat and energy savings with up to 92.5% AFUE. As a vital component to your home’s cooling system, it circulates cool air throughout your home and can help your air conditioner achieve added efficiency.
Model 355CAV The combination of technologies that help the Plus 95s deliver such reliably consistent comfort also provides significant relief to your energy bills. By replacing a typical, older furnace with Plus 95s, you can save up to $345 annually in gas and electricity combined. At the same time, this is the quietest gas furnace you can buy. Nearly continuous operation at very low speed means quiet, unobtrusive delivery oh heated air and significantly fewer start-up cycles virtually eliminates one potential source of noise. Model 359AAV  uses a patented primary heat exchanger which transfers an additional 11-15% of available heat into your home. Compared to an older, 60% AFUE furnace you may be replacing, the Model 359AAV could provide savings as high as 33% on your heating fuel costs. Model 359BAV  Combines two stages of heating and variable speed airflow for winter comfort far superior to standard single-stage furnaces. Nearly continuous low-heat operation maximizes economy while providing a steady flow of heated air. At 95% AFUE this furnace can save 33% over an older furnace saving you as much as $345 a year.



Whole-home air conditioning systems are central systems that rely on ducts to deliver cooled air throughout the home. An air-conditioning system provides cooling, ventilation, humidity control and even heating (if using a Heat Pump) for a home. Air conditioning units cool refrigerants in evaporator coils, over which air is then blown to be cooled and ultimately directed through the ducts throughout the home.

Typical air conditioning products include:

  • Heat Pumps
  • Central Air Conditioners
  • Evaporator Coils


Cooling A thermostat may be a control unit for a heating or cooling system or a component part of a heater or air conditioner. Thermostats can be constructed in many ways and may use a variety of sensors to measure the temperature. The output of the sensor then controls the heating or cooling apparatus.
