Air Conditioner Condensation Water Dripping - It’s the heat of summer or even the beginning of the season. You turn on your air conditioner for the first time. Hopefully, you’ve already had all the preventive maintenance checks done, and there are no problems. Everything is working fine, at least for now. Suddenly you notice water around the air conditioner, and you know you have a problem. You have air conditioner condensation dripping water everywhere. (more…)

Hot Water Boiler Economizer PreHeater | Energy Efficiency - This is a hot water economizer and is a big preheater for domestic hot water use. This hot water boiler plant serves a large community for heating and domestic hot water use. Domestic hot water is used for showers, washing dishes, laundry, etc, etc, etc….
The cold water supply from the city is routed through the economizer to be pre-heated before it goes through a heat exchanger and then the hot water storage tank. (more…)

Gas Furnace with Drain Pipes to Drain the Condensation.
Furnace Water Leak Condensate Problem - Richard, My furnace is leaking water. It is summertime, so I am not using it for heat except for the blower fan which is hooked up to the air conditioner and the heat. I know the pipes from the outside units run into a box on top of the furnace. I think that is a part of the air conditioner. What can I do to fix the problem if you know what the problem is by my explanation here? Dan

This MagicAire Air Handler serves as part of a large club and uses a DX (direct expansion) coil for cooling and a hot water coil in the air handler for heating. Many commercial air handlers are set up in this manner for heating and air conditioning. Hot water for the hot water coil is supplied from an oil boiler which supplies hot water to other air handling units in this building. In the center of the photo is the hot water coil and to the left, the line set which feeds the DX coil can be seen. (more…)

Air Handler Evaporator Condensation Drain Blower Compartment
This air handler has the access panels removed during the installation process so the HVAC installation technician can make the final connections and adjustments. In clear view is the air handler blower compartment with the air handler blower. The air handler blower is comprised of an electric motor, a blower wheel, and a squirrel cage which holds it all together. Attached to the outside of the squirrel cage is a run capacitor which is a functioning part of the electric motor. All these air handler components combined blows air throughout the entire HVAC system including the evaporator coil. (more…)

Air Handler Components. This article will take different types of air handlers and disassemble them part by part. This will give you a good description of each part and hopefully a better understanding of the air handler. Most of the components associated with the air handler are in the air handler. However, there are a few components which are not in the air handler but associated with the air handler.
There are some hot water and cold water coils which are not fixed in the air handler. They are downstream in the ductwork. There are also some gas and electric duct heaters which are mounted in the ductwork. They are completely reliant on the air handler for air flow. These systems will also be covered. Hopefully, this article will offer you a comprehensive look at the air handler, all its parts, and how it functions. (more…)

Water Dripping from Air Conditioner - We have 2 air conditioning units in our house and 2 pipes protrude from the roof. One of the pipes is dripping water. We were told to look for a blockage and to empty the pans. I don’t see where to check for a blockage. Any suggestions?
The air conditioning units we have: Bryant models 373LAV, 376CAV Downflow/Horizontal and 383KAV, 395CAV Upflow Gas Furnace. (more…)

This is an air conditioner condensation drainpipe that drains the condensation from the evaporator coil. The evaporator coil operates below the dew point when the system is in air conditioning mode. As humid air passes over the cold evaporator coil the humidity or moisture in the air condenses. The condensation runs down the coil and into a condensation drain pan. (more…)

This photo shows the air handler blower compartment. This is how the air handler is opened when the blower needs service or repair. The evaporator coil is on top of the blower which makes this an upflow air handling unit. The supply air ductwork will be above the AHU. Since this air handler is installed in a closet then the ductwork is installed in the ceiling and makes this an ideal installation for AC since cool air falls. (more…)
