4-19-19. Removed old furnace. Installed new daikin furnace. Install metal to connect furnace to duct. Installed and setup t6 WiFi stat. Installed coil. Ran lineset from condenser to coil and braised it. Pressure tested lineset. Pulled vacuum. Did start on ac and furnace. Connected pvc to exhaust and intake on furnace. Pulled 4 wire from condenser to furnace and connected with thermostat wire from thermostat. Reconnected electrical wiring to furnace. Put new 16x25x1 filter in. Ran new disconnect outside for condenser of breaker panel. Ran new drain hose from coil and furnace to floor drain. If floor drain backs up we will need to put in a condensate pump. Everything is running and draining properly. Thank you for choosing Black-Haak heating for your heating needs.

Ac clean and tune. Used coil refrigerant sniffer on indoor coil unable to find any indications of a leak of refrigerant. Cycled system. Checked and cleaned electrical compartment. Found that the contactor was very worn. Tested capacitor, tested lower voltage than recommended. Capacitor failed. Used megometer to test compressor. Tested showed that compressor failed inspection. Tested at 20 ohms. Used coil cleaner on condenser. Hooked up gauges and checked pressures and temps, ok. Tested sub cooling and superheat, both ok. Split was normal. Average life of this unit is 14 years, this system is 23 years old and in poor condition. Failure is expected. Second opinion recommended. System is cooling job complete.

Came out to perform the level 2 furnace cleaning. Burners and flame sensor are clean. Heat exchanger looks okay. Combustion readings were normal. No CO detected in the air. High limit passed the safety check. Temp rise was 46 degrees. Customer upgraded to a package cleaning during my visit and I did the AC right away. No leaks detected. Electrical components tested good. Capacitor tested in zone, however, I noted that it is starting to rust on top. Condenser was cleaned with water and nu brite. Refrigerant charge was good. Temp split was 17 degrees. All HVAC equipment is running properly at this time.

Performed furnace 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 and did make an adjustment, as well as performed a combustion test verifying no CO in the airstream. This system is 10+ years old average life span on these systems is about 14 years. As it sits we just replaced an inducer motor, the transition assembly is cracked and will need to be replaced, the igniter did test weak and I do foresee issues in the future, as well as the heat exchanger has a substantial amount of rust which is an indication of future issues as well. Do the age, condition, and cost to repair I highly recommend looking into our options and comparing the cost of replacement to repair. Job complete

Came out to install a new thermostat back plate and perform an AC check. I removed the original stat plate and placed, leveled, and secured the larger one in its place. With the AC check, I detected no leaks at this indoor coil. Electrical components tested okay. The capacitor is starting to weaken. The fan bearings are good yet. However, I did have to remove a rodent nest. A full cleaning is recommended due to the gap from previous maintenance and condition of the outdoor coil. AC clean and tune

Performed furnace 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, as well as performed a combustion test verifying no CO in the airstream, and lastly replaced 213 aprilaire filter and thermostat batteries. Also took the time to cycle in the AC system just to verify operations I did find a rodents nest in the system. Due to the age, condition, and cost to repair I highly recommend looking into our options for this system. I do foresee issues this summer with the AC system. Job complete

Completed AC replacement. Recovered refrigerant from the old AC and removed it. Set new condenser on a pad. Placed new coil in the plenum above furnace. Flushed the lineset and reconnected to the coil and condenser. Pressurised the lineset with 325 psi nitrogen to test for leaks and evacuated to approximately 300 microns. Released charge but will still need a start up done on it when it warms up. Thank you for choosing Black-Haak. Please take a moment to fill out our online survey.

Performed the level 2 furnace cleaning. The loud noise that the customer complained about is the venter motor. The motor bearings are worn and expected to fail. Upon further inspection, I found water damage in the blower compartment, possibly from the secondary heat exchanger. The primary heat exchanger is rusting and chipping. CO in the exhaust was larger than normal at 88 ppm. Average life of system is 12-15 years. Unit is currently 18 years old. Due to age, condition, and cost to repair, second opinion is recommended. Failure is expected. Even though the furnace is safe to run now, we cannot guarantee how long it will last after we leave today.

Completed Gas Furnace replacement. Disconnected and removed old furnace and then set new one on blocks in its place. Reconnected the gas, electric, PVC vent pipes, and duct-work to new furnace. Installed a new WiFi Thermostat and connected it to the Furnace. Run tested the furnace, but will still need a technician start up. The Office will follow up to schedule a technician to return to do the Furnace efficiency startup, which is required for warranty purposes. Installed A/C leveled it and set it on a new pad. Pressure tested it and ran it in a vacuum. We dumped the charge and needs a start up when it warms up. Thank you for choosing Black-Haak Heating. Please take a moment to fill out our online survey.
