Excellent Experience!!

A smoke detector, which was faulty was installed in my condo at the time of construction. At 10 pm the smoke alarm went off. My ceilings are very high. I contacted Black-Haak heating at 8am in the morning. A very polite young man was at my house within less than 2 hours of my call. He installed 3 new detectors & batteries. He was punctual, put on booties over his shoes and was very polite. Awesome experience. Highly recommend them!!

Ridiculously Exceptional Service!

We have been customers of Black-Haak since moving to Neenah in 2013. Today, I called to ask that a new filter be sent for our furnace/air conditioning unit. Due to an unexpected emergency, I explained our need for prompt delivery. Imagine our surprise when we were hand delivered a new filter within two hours of our call! WoW! Thank you!

install of furnace WELL done by tech's.

We had the furnace put in our home w/ air conditioner as an option after some remodeling is to be done. This entails moving the present A/C unit and replacing this unit. The contractor said they would be handleling this phase of the remodel also. We wish to allow the contractor do the A/C work that is in the bid. Thank you for your option on the A/C unit but we will go with what is stated. We still will use your service in the future.

Performed an air conditioner clean and tune. Used refrigerant sniffer to test indoor coil for possible refrigerant leaks, found none. Cycled system. Checked and cleaned electrical compartment. Found contactor worn. Tested compressor, came back in the normal range, but it is getting weak. Used coil cleaner on condenser coil. Hooked up gauges and tested pressures and temperatures. Found system slightly low on R- 22 refrigerant. Indoor coil temperature is 42, sub cooling is 23, temp split is 19. Average life of this unit is 14 years, this system is 24+ years old and showing signs of ware, due to age, efficiency, and cost to repair, second opinion is recommended. Future failure is expected. Job complete.

Came out to investigate a no cool. The door was not properly covering the switch and therefore, no power would turn the unit on. System is operating normal at this time.

Relocate supplies to plenum to get better airflow. Completed duct alterations. Removed the 12” x 8” piece of duct off the back of the plenum and patched the hole. Took the 4 existing supplies and humidifier bypass and relocated them to come directly off the plenum. By doing this the 2 upper rooms that were getting minimal airflow should now get more do to not being restricted by undersized duct. Reconnected the pipes and added balancing dampers in ones that didn’t have them. Thank you for choosing Black-Haak heating. Please take a moment to fill out our online survey.
