As always the technicians and service people that have responded from Black Hawk to our residence from 2004 to the present. We are elated with the rapore that they have with us, and explanation of questions. I want in-depth answers. And I can get them from Julian and Dan today and others that have been here before. They’ve been straightforward and honest and sincere. That means so much to me from a company that commands the customer first. I want you to know that everything from the top of the company to the bottom of the company has meant so much to me and my family for service and representation from your company for our appliances. I wanna thank you for that and I will continue being A sincere customer of Blackhawk in the future. Thank you for all

Found the problem when others couldn't

He was quick in finding a leak in my AC unit when another employee was unable to find it. He explained where the leak was and what needed to be fixed in an easy to understand way. He was very conscious of being able to answer all questions that I had.

Good Experience

2018-19 was a rough winter. Very cold. This is the first time in five years of generator ownership that my weekly test ran all winter...and it was the first year that Black Haack serviced the generator. Hopefully, 2019-20 will be a similar experience.

Put the refrigerant cap on the condenser unit.

Performed package clean and tune; inspected the condenser electrical compartment and tested components both the capacitor and contactor showing signs of wear, sprayed down condenser with coil cleaner, cycled the system on and checked pressures and temps. I then cleaned the furnace cycled the system on and I noticed last burner would not ignite cause system to retry, removed and cleaned the burners along with the flame sensor, cycled the system on and checked gas pressures also performed a combustion test verifying no CO in the airstream. Did want to note that the co in the exhaust was 75ppm this is an indication of future failure. These systems are currently operating but future failure is expected. I am including a quote to replace fireplace transformer. Job complete

No cool. Customer stated that the indoor coil was iced up twice. Checked indoor coil with refrigerant sniffer, found several indications of major leaks. Cycled system and hooked up gauges and tested pressures and temps. Found indoor coil temp was 9 degrees. System very low on charge. Average life of this unit is 14 years. This system is 24+ years old and failed. Second opinion is set for today. System not cooling. No charges pending results of second opinion. Job complete.

No cool. Found system off. No call for cooling. Customer stated that the coil was completely iced up yesterday. System is only 2 years old. Cycled system and hooked up gauges and checked pressures and temps. Found system low on charge. Added 1 dye capsule and 1 pound 8 oz of R410-A refrigerant. Indoor coil temp went from 22 degrees to 40 degrees. Subcooling is now 13. Checked indoor temp split. Found split to be 19. Recommend full ac clean and tune. Office will schedule return visit to check for any leaks with UV light. System is cooling at this time. Job complete. No charge for the dye and leak search due to age of unit. Clean and tune

Performed the level 2 package cleaning. Furnace: Burners and flame sensor are clean. Heat exchanger looks good. Combustion readings were normal. No CO detected in the air. Drain is clear. Heat rise was 34°. High limit passed the safety check. AC: No leaks detected. Electrical components tested good. Condenser coil is clean. Refrigerant charge was normal. Superheat was 18° with a 17° temp split. All equipment is operating properly.

No cool. The condenser wouldn’t turn on with a cooling call. I checked the electrical compartment and found a wire burnt off the contactor. I reconnected the wire. The contactor, capacitor and compressor are worn and in poor shape and causing the unit to burn up wiring. The air conditioner is cooling now. The air conditioner is 15 to 20 years old. I recommend replacing the air conditioner because the compressor is drawing more amps which is causing the wires to burn up, it will most likely do this again.

No cool. Tom said the air conditioner would turn on and off randomly. I cycled the air conditioner. Checked the pressures. Found the air conditioner was turning on and off on its pressure switch. I checked the filter, it was plugged. Installed a new filter Tom had. Cleaned the drain line. The air conditioner is cooling now. I recommend having maintenance done to it. Office will call to schedule air conditioner maintenance.

Closed service valves and tried to pull the refrigerant into the condenser. Valves would not fully seat. Refrigerant was going back to the coil. Used reclaimer and reclaimed refrigerant into tank. Cut linset and removed wiring. Capped wires and disconnected disconnect. Moved condenser into garage per customer. Once concrete is done, customer will have condenser reset. Refrigerant will need to be added at that time. Job complete.

Installed new A/C and removed the old one. Ran a new line set for the A/C and hooked everything back up. Pressure tested it to 400 and put it in a vacuum down to 200. Related the charge and did a start up on it.
