Professional and friendly service!

The main office called and asked if the Service Tech could come earlier than scheduled. The tech arrived promptly, confirmed the information I shared with the main office, and began working. While performing tasks the tech explained his findings and what tasks were being performed to correct the issue(s). Tasks were completed in a timely manner and arrangements where made for follow-up service due to weather restraints. The tech was professional, friendly, and respectful.

Always satisfied

Black Haak has been helping us with our furnace checks and repairs for almost 30 years! They are always prompt, polite, professional, and reasonable priced. Today Hunter changed the filter on my Aprilaire unit. I expressed interest in knowing how and he graciously taught me. Thank you!

Quick Response, Fantastic Help

I called on a Saturday afternoon and had their technician, Brad, at my house in about an hour. He was friendly and professional throughout our A/C being serviced. He explained everything thoroughly and made sure we understood what needed to be taken care of. We appreciate the quick response!

Performed package clean and tune; inspected the exhaust and intake PVC ensuring all connections were secured, removed and cleaned the burners along with the flame sensor, cycled the system on and checked gas pressures, performed a combustion test verifying no CO in the airstream, blew off and wiped down air cleaner (due to current condition I am including a quote for the upgraded air cleaner). Inspected condenser electrical compartment, sprayed condenser coil with cleaner, cycled the system on and checked pressures and temps, this system is currently operating normal and cooling at 19 degrees job complete

Performed Package clean and tune; inspected the condenser electrical compartment and tested components, sprayed the condenser with coil cleaner, cycled the system on and checked pressures and temps subcooling sitting at 8 degrees with an 18 degree temp split. System is currently operating normal at this time. Inspected the exhaust and intake PVC ensuring all connections were secured, removed and cleaned the burners along with the flame sensor, cycled the furnace on and checked gas pressures, performed a combustion test verifying no CO in the airstream system is heating at 46 degrees at this time. Recommend replacing #10 water panel in the humidifier before Fall. Also did want to mention the 20x25x4 filter is not the correct filter for the box I recommend using the correct aprilaire 213 filter this is to prevent any issues with possible warranty claims.

Ac clean and tune. Checked indoor coil with refrigerant sniffer, found several indications of a leak on coil. Current price for R-22 refrigerant is $350.00 a lb. Checked filter and cleared drain line. Cycled system. Checked and cleaned electrical compartment. Found capacitor worn and leaking. Tested compressor and fan motor, both tested low. Used coil cleaner on condenser coil. Hooked up gauges and checked pressures and temps. Indoor coil temp was 37. Subcooling was high at 17. Checked indoor split. Found a 15 degree split. System refrigerant is lower than desired. Average life of this unit is 14 years. Due to age, condition, and cost to repair, second opinion is recommended. System is cooling, but future failure is expected. Furnace clean and tune. Cycled system. Removed and cleaned burners and flame sensor. Both ok. Found igniter showing signs of getting worn. Checked heat exchanger, all chambers are worn and rusted. Checked and adjusted gas pressures to maximize efficiency. Checked

Came out to recheck the refrigerant pressures and check for a possible leak. I found the filter was clogged and threw the gauges off a little bit. After replacing the filter, my pressures stabilized. I put a heat blanket over the unit for safe measures and everything checked out fine. I didn’t find any indications of a leak at the coil or linesets.

Performed AC clean and tune; inspected the evaporator coil for possible leaks did find an indication on the metering device, i then inspected the condenser electrical compartment and tested components new capacitor and contactor compressor tested out ok electrical system is currently working fine, next i sprayed the condenser coil with coil cleaner, cycled the system on and checked pressures and temps superheat 31 degrees 3 degrees of sub cooling with a 13 degree temp split. This system is low on charge i would recommend looking into options. Possible frozen coil in the future. Job complete
