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…)

Trane Air Handler Making Dust | HVAC Troubleshooting - I would appreciate someone in the Trane organization that would please tell me why since installment and still 5 years later my house is nothing but a dust pit. I am not exaggerating. You can wipe dust blankets DAILY off my walls, floors, furniture. I have been, since the installation, asking someone to help me.
My original installer put a filtering system “like used in coal mines” - did not help. I have had independent HVAC inspectors who cannot understand nor have any reasoning for the dust. One thing was that the original TRANE installer did not put sufficient air return duct in my house.
CAN SOMEONE HELP OR AT LEAST GIVE ME AN ADDRESS/TELEPHONE NUMBER WHERE I CAN CONTACT THE MAKER/OWNER OF TRANE?
The air handler coils should be checked for dirt and debris which may have been sucked into the air handler inadvertently. Some air handlers have filters inside them before the coils. It is a good time to change the filters when making this check.
Any dirt or debris on the coil(s) should be removed immediately as these things will impede airflow through the air handler and throughout the entire system as a whole. Dirty evaporator coils can cause AC problems. Some air handler coils are installed in the air handler cabinet while other coils are installed in the ductwork. (more…)
Air Handler Return Dampers | HVAC Components - These return air dampers serve a large air handler on a rooftop. This return air damper ends up in a mixing box inside the air handler where the return air from the building mixes with the outside air from the economizer. (more…)
These evaporators serve a large complex where natural gas is unavailable. The complex needed fuel for boilers for heating and domestic hot water so these evaporators were installed too along with two very large LP tanks to handle the heating needs of the complex. As liquid propane (LP) has a specific weight of .504 (where water is 1) and propane vapor has a specific gravity of 1.5 (where the air is 1) making propane vapor 1.5 times heavier than air. (more…)
