Fantastic Service and Follow Up

DiBiase worked with me to upgrade my air handler to heat better. While that was going on they also came to the rescue to help my Mother in Law whose heater had to be replaced all of the sudden. They dropped everything to get her system set up on a Saturday. They also thoroughly documented everything and sent pictures and followed up. What a great business and I am glad to not only use them for my home but also for my family.

Mrs. Latha was concerned about filter reminder appearing too frequently. There are no other alerts on the thermostat. With Mrs. Lathas approval we removed filter replacement reminder from tstat installer options. Verified TD of heat pump 22F, refrigerant pressures 115 PSI Lo; 305 PSI Hi. and compressor amp draw 4.83. Mrs. Latha described supply air as being cool. We explained that typical supply air temperatures of heat pump systems are lower than those of gas/fossil fuel systems. System has been satisfying desired tstat temp. System is operating well at time of this service call.

Found climate master geothermal system running when I arrived. Shorted outtest pins on cxm2 control board to recall fault history. Found it had a fault code 4 in the system. This can happen when the water loop temp becomes too low and sensor in coax coil shuts down system until loop temp rises. Found air filter was slightly dirty, ( replacement with one homeowner provided) recommended to homeowner that if this code would happen again we may need to increase water pressure in the geo loop with special needle fill system. Geo is working fine now with a 23 degree temperature rise. Geo water loop split is 6 degrees which is adequate.

We removed the oil furnace and ac coil from basement, removed oil line from tank and shut the valve off. Removed all plenum work that was there before coming off of the supply duct. Removed old line set and outdoor unit including the outdoor disconnect box. Then installed new line set and thermostat wire from furnace to the outdoor unit. Installed new gas furnace and raised it up with feet, installed a return drop kit and sealed it to a 413 April air media filter and then to the furnace. Extended the original return by thermopaning over to the new return duct and sealed it in. Made new plenum for the supply and sealed it to the furnace going into original supply trunk. Cut new 12x12 floor return grilled and thermopanned the bay it was going into and then added a 12 inch sticky collars to it and the ran 12 inch flex to furnace return duct and sealed it in place. Added another return on the return duct itself to pull air from basement, and put a 12x12 return grill over top of the hole i
