Great service, fast, qualify

Couldn't be happier with our decision to use Black Haak for installation of our new air condition system! Great customer service, fast installation (had to quit early one day due to rain, but still finished ahead of time) and the products work just as the salesman said they would.

Furnace clean and tune. Cycled system. Checked heat exchanger. Found rust in the front and on the first bend of primary heat exchanger. This is common with burner damage and corrosion. Checked, removed, and cleaned burners and flame sensor. Cleaned burners as best I could. They are now in working order. Checked and cleaned flame sensor. Found that flame sensor is chipped. This will cause flame sensor failure in future. Ventor motor bearings are also worn and noisy. This motor will seize at any time. Rust throughout the system. Found water leaking from Ventor motor gasket and also a cracked transition assembly. Water rust spots also found in blower compartment. Igniter is worn and replacement is recommended. System is 13 years old and there are several issues throughout the unit. Due to age, condition, and cost of repair, second opinion is recommended. Future failure is expected. Job complete.

The infloor heat wasn’t heating properly. I checked the system. I found the infloor systems was airlocked. I purged water through the system to get the air out of the piping. I cycled the system. All three zones are heating properly now. I recommend having a clean and tune performed on the geo unit. Office will call to schedule the clean and tune.

Performed leak search; found leak in high side braze joint at the condenser, soldered joint and releases charge, added 1 pound of refrigerant bring our subcooling up to 8 degrees as well as a 17 degree temp split. This system is currently operating normal at this time. I am including a quote for an electronic air cleaner this will reduce the allergens and particles in he home dramatically compared to the allergen filter in place. Job complete

Performed AC safety check; sniffed the evaporator coil for potential leaks, cycled the AC on to verify operation, I did inspect the electrical compartment the capacitor is 10 years old and is showing definite signs of wear I would recommend getting this replaced with the AC clean and tune, the outdoor coil is getting plugged with cotton and other debris i highly recommend getting this system cleaned on a warmer day so we can spray down the outdoor coil with a chemical solution as well as to check pressures on the system to prevent any future issues. This system is currently operating normal at this time. Job complete

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. Put a new WiFi Thermostat by the drop. 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. Thank you for choosing Black-Haak Heating.
