Love the good service

We bought a new furnace a few years ago from Black-Haak because of their great service. The install went well and we are very happy we picked them. In some internet advice on brands, it stated that the service is the most important item when buying a new furnace. This furnace has saved us a lot of money over the old furnace and we have no regrets.

Replaced both bath exhaust fans with customer provided units. Also ran 4” hard pipe from each fan to the J-block vent on exterior of attic gable end. Sleeved the hard pipe with 4” insulated flex to insulate it from attic temperature extremes. Checked CFM on each fan with a balance hood and found master bath to be pulling approximately 85 cfm and the hallway bath fan to be pulling approximately 75 cfm. The fans are rated at 110 cfm each but the loss could be due to length of runs and the number of elbows in each run (2). Also found that there was window screen wrapped around the J-block vent which I assume was to keeps bugs out. This screen was plugged with dust and dirt so I removed it to facilitate better operation of the fans. Left old fans onsite in case owner wanted for any reason.

Came out to perform (2) level 2 furnace cleanings on both units. The igniter for the north unit cracked during inspection and was replaced free of charge. The south unit has blower motor bearings that are wearing out. Both heat exchangers have minor rust and are chipping. Units are both heating properly at this time. We will return with the filters.

No heat upon arrival, found that the furnace control board is intermittently kicking the furnace on and off, it is also putting CO into the airstream the times it does decide to run. This sytem is 25+ years old because it is pushing CO in the airstream this sytem is not safe to operate at this time we’ll have to return to replace the system. Job complete

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, performed a combustion test verifying no CO in the airstream, and lastly replaced the 16x25x1 filter I am including a quote for an electronic air cleaner due to the amount of dust found on the blower wheel. The filter I pulled out today is too restrictive on the sytem causing the blower motor to pull more amps causing strain on this 5 year old furnace. Also found a couple sections on the gas line that leaked gas i did remove and re doped theses connections. This system is currently operating normal and heating at 47 degrees at this time.

Performed the level 2 furnace cleaning. Burners and flame sensor are clean. Heat exchanger looks good. Gas and exhaust levels are normal. No CO detected in the air. Drain is clear. Heat rise was 46 degrees. Unit is heating properly at this time. We will return in spring for the AC.

Cut old pvc exhaust pipe apart at the wall near where it exits the basement. Re-piped the exhaust from outside in to where the horizontal run begins at main beam. Installed three new 3” pvc 90’s and one new 3” 45. Cleaned and glued fittings taking care to make sure they didn’t push apart. Using an s-slip I shimmed the plenum above humidifier to cause the upper portion of the humidifier body to lean back slightly. This in turn leveled the front of the humidifier housing. Ran the humidifier for several minutes to check for any leaks and found the water to only be running into drain as it should. Thank you for choosing Black-Haak Heating.

Performed level 2 furnace cleaning. I found the transition assembly had a crack and was leaking. The leak caused rust in both furnace compartments. I also found the ventor and blower motor bearings were starting to wear out. The heat exchanger is rusting and gave a lot of backdraft with the smoke test. No CO detected in the air at this time. Due to age, condition, and cost to repair, second opinion is recommended. There’s a rag in the furnace to help collect the leaking water.

Performed 1st year furnace cleaning. Cleaned the burners and the flame sensor. Wiped down the inside of the furnace. Checked the furnace heat exchanger. Cycled the furnace. Checked the motors for proper operation. Cleaned the drain line. Checked the gas pressure and performed a combustion test. The furnace is running normally at this time. Looks like the air conditioner will be due for its cleaning in April. An air conditioner cleaning is recommended to maintain the warranty and the efficiency of the unit.
