A very unique attic system replacement.  This house has 3 a/c air handler units located in an attic above the upstairs landing.  Access to the units is from a nearby bedroom, then squeezing thru a maze attic roof-lines.  2 of the attic units needed to be replaced, but there was literally no way to get them down- the tight access was smaller than the units.  Red markings on the 1st 2 photos show where the units are located above the ceiling.  (Not sure where the inspector was when this house was being built!)  We had to cut a large hole in the ceiling and use a crank up "genie lift" to get the new units up into the attic.  Notice the feet hanging down thru the hole.  While we were at it the homeowner elected to put a 3rd unit up in the attic for future use when unit #3 fails.  Fortunatly, the other 21 a/c systems had easier access!

This medical office was flooded by a water heater in the suite above it.  A contractor has already removed the affected sheet rock and and has set in place blowers and a dehumidifier to dry out the space.  Our job was to examine the ductwork (located above the drop ceiling) and replace the affected areas.  We cut out sections of the rectangular ductboard trunkline and examined them for moisture.  The piece you see here was moist.  We also examined sections of the round duct work for moisture both in its spiral lining and outer insulation.

 Vent problems at an old building in Buckhead.  The old, externally mounted, single-wall vent pipe has crumbled, leaving only its mounting bracket and rotting elbow penetrating the building.  If you look closely, you will see in the middle picture that the vent pipe is not there!  You are looking at heat stains from the leaking vent pipe.  Upon closer inspection we found the section of pipe inside the office/warehouse leaking, too.  We replaced both sections with double-wall vent pipe, completing the job with a new strap and vent hood.

Ken and David are replacing two complete systems in an Alpharetta home.  This installation included two furnaces set side by side in an attic.  Note the details you should look for in a good installation:  armor flex insulation the full length of the suction line (to avoid water dripping on the ceiling during normal use), double wall vent pipe, a pvc drain union for repeated drain access, and a secondary drain pan and float switch.  The attic roof has been sprayed with foam insulation previous to our arrival to keep the heat out.

Here we are installing two residential heating and cooling systems in Dunwoody.  The old air conditioners were covered by bushes.  We had to carve a discreet path into the bushes in order to remove the old units and bring in the new ones.  It was especially important to cut away enough brush so that the condensers could "breathe".  Otherwise they would continue to recycle the hot air produced from the heat transferred from inside the house to the outside.  This state of affairs would reduce cooling capacity and efficiency, and could shorten the life of the units.  Note the level condenser pads, insulated thermostatic expansion valve, secondary drain pan under the furnace with an emergency cut-off float switch and the PVC drain union at the evaporator coil to allow repeated access to the drain line.
