Great

Hi, My satisfaction with Dibiase continues with Chris's visit today. During his follow-up visit concerning my new HVAC system, he explained some alterations he made, responded to my questions and offered suggestions for best settings on the system. I appreciate how comfortable it is working with your company.

Upon arrival found thermostat off, set thermostat to call for heat and furnace did not come on, system need troubleshooting,,,,after visual inspection and looking at the current condition furnace is is bad shape, super dirty and extra time will be needed, informed customer about situation and also quoted for deep cleaning on furnace and advised customer furnace is in bad shape and will need a lot of repairs, customer will contact her home warranty, can’t tell how old the furnace is but it is old, final recommendation is system replacement

Upon arrival for precision heat tune up I found the fan was constantly running. Upon further investigation I noticed water coming from the inducer assembly. Leaking into the bottom cabinet and control board area, the control board was bad and causing the fan to run continually. These repairs are highly recommended. Furnace is still operational in heating mode however fan will continue to run. Checked gas pressure and flame sensor replaced humidifier pad customer provided and 16x25x1 air filter

Pump Down 410-A refrigerant and reclaim. Remove the old TXV by mechanical connections or sweating the TXV out to remove. Remove the current Filter Drier on the Outdoor Unit. Braze in new Outdoor TXV or reinstall using Mechanical Connections. Braze in a new Bi-Directional Filter Drier. Pressure test system and inspect connections to insure system is holding pressure and there are no leaks. Perform Triple Evacuation on system to below 500 Microns. Add Manufacturer charge to system and put in operation. Test system in Heating Mode and record Refrigerant Temperatures/Pressures. Add additional charge as needed. 10/28/19. Pumped down system to 365 microns, added 7 lbs of r 410 and tested system in both heating and cooling. Ambient air temp is 68 degrees. Pressures in cooling were 241/128 with 9.3 subcooling. Then in heating mode pressures were 355/122. Heat pump is working again.
