Residential whole house electronic air cleaners are sold and installed by trained HVAC technicians. Most are put in the return or cold-air section of a heating and air conditioning system; some are installed in a central return grille.

Today’s building owners are more concerned about saving money through energy efficiency than ever before. Fortunately, air-to-air energy recovery ventilators (ERVs) help them save energy and money by recapturing 40-80 percent of the energy of the exhausted building air and using it to pre-condition incoming ventilation air.

Chilled beams have been used in Europe and Australia for approximately two decades and are just now becoming better known in the United States marketplace. While chilled beams offer numerous benefits, their energy efficiency makes them especially attractive for building owners and facility managers.

Direct gas-fired air heaters offer safe, flexible, fuel efficient and cost effective building operation solutions. This heating equipment provides make-up air to regulate ventilation rates and offset building heat loss for millions of commercial and industrial customers.

Direct heating products offer alternative solutions to heating spaces within the home where other types of heating sources may not be practical. Direct heating equipment is often referred to as space heating, spot heating, zone heating, or room heating equipment.

More homeowners than ever before are aware of ductless air conditioning systems. That is because those who already have installed them are getting the word out about how economical and efficient they can be, among their many other benefits.

Electronic gas detection technologies have made it possible to quickly and easily detect even the smallest and insignificant gas concentrations.

Geothermal heat pumps (GHPs) have come a long way since they were first introduced in the U.S. market somewhere around the late 1970s. What used to be viewed as somewhat of an alien concept by many homeowners has grown more mainstream, into a multimillion dollar industry in fact.

Heat pump pool and spa heaters absorb heat from the air and transfer it to the water, making the heating process efficient, ecological, and cost effective.

Did you know that in cold climates, the relative humidity of the outdoor air can be as low as 10 percent — about the same as the Sahara Desert? Dry air isn’t just uncomfortable. It can cause a variety of unwanted conditions, including:

Whether buying a new home or remodeling an existing home, utilizing hydronic heating provides the ultimate in heating comfort, efficiency, and cleanliness.

Chillers provide comfort for people, and a controlled environment for processes and equipment in a variety of facilities and environments. Chiller applications must be able to deliver cooling and heating on demand, consistently, efficiently, and in an environmentally-friendly manner.

Thermal Energy Storage (TES) is a general term describing a technology that stores energy created at a particular time and makes it available to be used at a later time.

Homeowners use each room in a home differently. The size of each room, the level on which it sits, the direction it faces, how much window area there is, how the room is used, when the room is used, and who uses it are factors that affect the temperature and comfort level.
