Process should consider complexity of project.

The technician did a good job, but I felt the pricing for my project was too high given the low complexity, and I was just given a standard price-not considering that the wiring was almost exclusively outside the walls.

AC check-up/repair, furnace Installation, and final check-out

The service started a couple of weeks ago and ultimately we have a working AC system and a new furnace; we are very pleased. The service, scheduling, promptness, courtesy, and workmanship have been excellent. We'd like to thank Anthony, Dan and Dan, Craig and Craig, Kory, Scott, and Tim. Let's not forget McKenzie and Andy with the scheduling and follow-up. Thanks again.

Performed the level 2 furnace cleaning. 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 30°. Unit is heating properly.

Customer stated that over the last three years, when he would run the heat and dishwasher, it would blow the breaker. Both the dishwasher and furnace are on the same 20amp breaker. This appears to be overloading the circuit. Called Joel and he quoted $175.00 plus tax to place them on different breakers.malso recommended a full electrical inspection of home to ensure no other issues are present. This service is 299.95 plus tax. I highly recommend this service due to current electrical issues. Safety check on furnace. Cycled. Heat exchanger is ok. Flame sensor and igniter are normal. Some rusting present due to crawl space location. No CO found in airstream. Normal levels of CO and XS air in exhaust. System operating normal at this time. Job complete.

Cycled system. Hooked up gauges and checked pressures and temps. Both were as normal and no different from last time. Low load conditions indoors and outside, but pressures were normal after condenser manipulation of ambient temps. System operating normal at this time. Job complete.

Came out for the leak search. I checked the indoor coil and copper line sets. No leak located. I put a tent around the outdoor unit and check the coil. Again, no leak detected. Refrigerant pressures were stable and haven’t moved since my last visit. I recommended having us return next spring for an AC cleaning to keep an eye on the unit.

Customer stated that water was building up on top of furnace cabinet. Furnace is not causing this issue. Customer wanted ac safety inspection done instead of furnace clean and tune at this time. Checked and cleared drain line. Found some debris in drain line, but it was minimal. Looked into drain elbow and found coil pan was very rusted. Checked indoor coil with refrigerant sniffer. Found indications of larger size leak on coil. Cycled system and checked pressures and temps. Found indoor coil was at 30 degrees. Subcooling and super heat were both off indicating that system is low on charge. Indoor temp split was 15, this is low compared to recommend temp of 20 degrees. Compressor and fan motor also tested low, this will lead to higher utility bills and eventually complete failure of compressor. This will cause indoor coil to freeze. When the ice melts, this will cause water to drain into and on top of furnace cabinet. Average life expectancy for this unit is 14 years. This system is o

Wired in new add a wire system. Removed old thermostat and installed new T4 thermostat. Cycled system. Found that thermostat was not able to call system. Checked zone board and found that board is not sending signal to furnace. Called install crew and asked about this issue. They stated that the board was an issue on install and they had to bypass board. Office to follow up about options. Home is currently not two zone, it’s only one zone. My job complete.

Performed the level 2 furnace cleaning. Burners and flame sensor are very dirty and corroded. There’s a lot of rust from water damage in both compartments. Venter motor is also wearing out. The heat exchanger has excessive amounts of rust and chipped metal. The CO in the exhaust was high at 114. No CO detected in the air at this time, however, the unit is in very rough shape. Average life of system is 12-15 years. Furnace is currently 15+ years of age. Due to age, condition, and cost for future repairs, I’m recommending a second opinion with our service manager. The unit is currently safe to operate for now, however, we cannot gaurantee for how long.

Ac clan and tune. Homeowners stated that ac unit runs long and cooling does not go through the home as they expected. They have just moved here. Cycled system. Checked pressures and temps. Found indoor coil temp was 40, subcooling was 13, indoor temp split was 17. Checked and cleaned electrical compartment. Tested compressor with megohmeter, found compressor tested ok. Fan motor also tested ok. Capacitor is worn and hard start kit is installed. Contactor is worn but operating normal at this time. Used coil cleaner on condenser coil. Rechecked pressures and temps. Same results found. Dryer vent is located directly behind condenser and condenser is undersized for home cooling needs. Average life expectancy for this unit is 14 years. This system is 20 years old an. M mv. d showing signs of being worn. Even though system is cooling at this time, future failure is expected. Job complete.

Completed AC replacement. Recovered the old refrigerant and disconnected the old condenser and evaporator coil. Set new condenser on a new pad and installed the new coil in the new ductwork we installed on top of the existing furnace. Ran a new lineset between the coil and condenser and brazed it to each. Pressurized the lineset with 500 psi nitrogen to test for leaks and then evacuated to 500 microns. Released the new refrigerant charge and did a complete start up procedure adding refrigerant as needed. Thank you for choosing Black-Haak Heating.

Furnace start up. Cycled system. Checked gas lines for leaks, none found. Checked venting and drain line. Ok. Checked incoming and outgoing gas pressures. Adjusted gas pressures to maximize efficiency. Checked electrical connections and clamps. Tested levels of CO and XS air in exhaust, normal levels found. No CO found in airstream. Tested temp rise in low and high fire rate. Both were normal. Minimal adjustment needed. System operating normal at this time. Job complete.
