Came out to investigate a no cool. Indoor blower was running but the unit outside wouldn’t kick in. I opened the electrical compartment and found the capacitor blown out. I replaced the capacitor and the unit started right away. Unit is cooling properly. We will come back to perform an AC later.

Fireplace. Customer stated that the remote for the fireplace was not turning the fireplace off and on. She changed batteries in the remote. I cycled the system with remote, no response. Changed batteries in the receiver and system fired with remote, but would not turn off with remote. Cycled several times until it went out. It was not cycling with remote, intermittently. Removed receiver and cycled system with wall switch with no issues. Diagnosis is the the remote system is failed. Recommend getting new remote system and having us wire it up for her. Office to quote and follow up. Furnace. Cycled system. Checked heat exchanger, minimal rust and corrosion and no rust found. Checked and cleaned burners and flame sensor. Checked ignition system, ok. Checked gas pressures. Normal levels of co and XS air in exhaust. No co found in airstream. System operating normal at this time. Filter is dirty, customer will replace filter in the next few months. System operating normal at this time. Cu

Completed gas furnace replacement. Disconnected and removed the old furnace and set new furnace on blocks. Reconnected the gas, electric, pvc venting and ductwork. Installed a new T4 thermostat and connected it to the furnace. The installation is complete but the office will contact you to schedule a time to have one of our service techs come do a complete start up procedure. Thank you for choosing Black-Haak Heating and Electrical. Please take a moment to fill out our online survey.
