Total Professionalism




These folks totally go out of their way to make sure you get the best products and customer service possible.Within 2 hours of our old furnace failure, Rick was at our home measuring and checking to make sure we replaced the dead furnace with the best possible match. Mark and Jason arrived on time in the morning to remove the old furnace and had our new furnace up and running in about 5 hours or so. Totally courteous and very professional. The fact that the recommended Daikin furnace has a 12 year Parts and 12 year labor warranty really sets a homeowners mind at ease. This old house is more comfortable than at any time in the 22 years we have lived here, with no cold areas like before. Can not say enough about these folks. From the initial call, to the installation, it was more professional than any contractor I have ever worked with!

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. Installed a new WiFi Thermostat and connected it to the Furnace. 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.

We came out to investigate a no heat. The furnace would continuously light and kick out. We found a large amount of water built up in the drain line by the exhaust. After clearing the debris and cycling the unit four times, the furnace had no issues running. Unit is currently heating properly. We mentioned to 5e customer about a cleaning. They said they will call back if interested.

Came out to look at a humidifier. The unit looked like it was mounted with duct tape before it fell. There was a lot of mold built up on the interior. I was able to temporarily mount the humidifier back to the duct work for testing. I cranked the humidifier stat all the way but it wouldn’t start. Weather conditions may be the reason it wouldn’t work, however, it looks like it hasn’t ran in quite some time.

Came out to investigate a no heat. Board was reading a limit fault code again. Filter was clean. I had 24v coming from the furnace. I took the limit out and flicked it with no success of ignition. We either have another bad limit or a board issue. We will return with the parts as soon as we get them in.

Completed relocation of (2) Daikin air handlers in the attic. Reclaimed refrigerant and disconnected the existing air handlers from the condensers. Unhooked the ductwork and removed the air handlers. Removed all indoor air quality components. Using threaded rod and 1 5/8” strut we hung the air handlers and secondary drain pans from the roof trusses. Fabricated new duct work to reconnect the supply and returns back to the air handlers. Reconnected the electric, drains and linesets. Re-installed the Hepa filters and UV lights. Wrapped all duct work with R-10 foil back insulation wrap. Pressurized the linesets to 325 psi with nitrogen to test for leaks, then evacuated to 450 microns. Will still need to return to do a complete AC start up procedure. Thank you for choosing Black-Haak heating. Please take a moment to fill out our online survey.

Came out to investigate a CO leak. WPS said they found high CO levels by the furnace. I took apart the unit and found large amounts of soot and chipping. One cell was completely black. The heat exchanger is bad and due to this, I had to condemn the furnace. Photos are uploaded. We will need permission from blue frog before moving forward.

Performed the level 2 furnace cleaning. We found the primary heat exchanger was starting to rust and chip. No cracks located at this time. After doing the combustion test, we noticed the excess air was a little high and indicates the secondary heat exchanger is starting to draft back. Venter motor bearings are also starting to sound worn. Due to the age, condition, and cost to repair, second opinion is recommended. Furnace and AC cleaning
