Why Choosing Fujitsu Heat Pumps Is Energy-Efficient

The ductless mini split Fujitsu Heat Pumps are similar to regular heating systems and have been in use for years. There is one very significant difference between this system and standard systems however. While the standard system has duct work and registers, the heat pump sets the air handler directly in the room. Each room that is to be heated has a small wall unit installed. Continue reading

HVAC Economizers

HVAC economizers are called DDC systems in industry parlance. DDC stands for Direct Digital Control, basically computerized controls of HVAC air handlers instead of using mechanical systems to control the use of the air handler and other components. Computer technology has been able to provide dramatic energy savings for years, but the real advance recently is the ease of use for air conditioning services Denver technicians. Instead of being pre-installed at the factory, now your HVAC technician can modify the DDC settings on site. Continue reading

Fan and Heat Relays in the Air Handler

The relay between the air handler control unit and the blower motor is called a fan or heat relay. If the thermostat fan setting is “on” then the relays do nothing but keep the fan running. Otherwise, when the air handler controller asks for heating or cooling the relay switches the fan on. Continue reading

Heating Air Handlers

Usually the air handler is the unit that provides heat, but some more advanced commercial and residential heating systems use zoning with remote heating. In this case the handler just provides air while the heaters provide zoned heat. Even inside air handlers there are multiple forms of heat energy. Continue reading

The Energy Efficiency of a Hydronic Heat Exchanger

The hydronic heat exchanger is popular in water to air or forced air heating systems. As water is sent to the heat exchanger, it is moved throughout the duct system by an air handler that pushes heated air at the right volume into each room to ensure proper heating within the home. Booster coils can also be utilized to super heat air in large duct systems where a single air handler is used. Continue reading
