Review of Black-Haak Heating

Parts are on order and furnace is working for now, parts to come next week. Dan explained things in terms I could understand and am following his recommendation to the letter. May be pricey, but get only what you pay for today.

Review of Black-Haak Heating

We were happy with the service provided and the explanation of our problem with our AC and then having the manager come out to also take a look to see if he agreed with the issue. Nice to know they have our back.

Completed installation of an HRV. Ducted the HRV unit to the furnace return duct, and to an intake and exhaust hood that penetrate the basement walls to the exterior of the home. Installed the control on the wall under the thermostat and ran wire to the HRV. Also ran a 2 wire to the furnace to interlock the HRV to the furnace fan. Run tested the unit but will schedule a time for Rick to come do a walk through. Thank you for choosing Black-Haak Heating and Electric. Please take a moment to fill out our online survey.

Furnace clean and tune. Removed and cleaned burners and flame sensor. Ohmed igniter. Cleared drain. Inspected electrical,gas piping and venting. Ran and tested unit. Found CO to be a bit on the high side, was unable to test due to a non operating gas valve port. Will have to return with new gas valve and adjust gas pressure and test unit again. All other systems are operating safely at this time. Have a wonderful fall, Brennan

Furnace safety inspection. Cycled system. Checked heat exchanger. Found some rust and corrosion, but no cracks found with powder test and camera check. Found burners very rusted and corroded. Checked and cleaned flame sensor. Ok. Checked igniter. Ohmed and tested ok. Checked and adjusted gas pressures to maximize efficiency. Checked electrical connections and clamps. Found clamp on exhaust venting. Tightened clamp. Checked levels of CO and XS air in exhaust. XS air found to be 162. This is higher than desired. This is caused by a probable secondary partial blockage. This will continue to get worse over the next few years. CO was 13. This is within normal range. No CO found in airstream. This system is in need of a maintenance. Other than normal wear and usage, system is operating normal at this time. Yearly maintenance is recommended. Job complete.

Was here for a furnace no heat. The furnace wasn’t running when I got here. Reset power to the furnace. Cycled the furnace. The burners would light but the blower motor wouldn’t turn on. Found that the circuit board wasn’t allowing power to the blower motor. The furnace is 17 years old. Recommended that they get a second opinnion with my supervisor Dan to go over repair or replace options. Office to schedule Dan for 9am on Monday morning.

Boiler would make a whiny noise. I cycled the boiler. When it had an output of 150000 btu the exhaust blower shroud would vibrate and make a noise. I removed the shroud. We will need to order a new exhaust blower and come back to install it. The boiler is heating at this time.

No heat on oil furnace. The burner was locked out. I checked the cad cell, it was good. Checked clean outs, they were clear. Cycled burner. The burner would try firing but it wasn’t getting constant oil flow. I bled air from the oil line. Cycled the furnace multiple times. It’s heating properly now. No charge since I just cleaned it and forgot to bleed air out of oil line.

No heat on geo unit. I checked unit for fault codes. Found a flow switch fault code. I cleared the code and cycled the geo. It cycled through hydronic heat normally. I checked the flow switch, found it wasn’t aligned correctly on the pipe. I corrected the flow switch alignment. Checked flow center water level. Water is to the top. Level is good. Cycled geo in forced air heat. It’s working properly.
