I had 3 estimates done by 3 reputable companies. One of these companies I have been using since moving to the area. From our estimate to our complete install, this team is amazing!!! I would recommend them to ANYONE!! I would also like to say that they may not be the least expensive all the time, but you WILL get what you pay for !!!

This company was great! We called last night. They came this morning and fixed everything by 3 today. The communication of the company was superb. They text pictures of the people coming to service the house. It made me feel comfortable letting the person Inside. All staff members wore masks, booties and gloves. They were all friendly. They made sure to solve the problem and install a new air conditioner Immediately. I highly recommend this company. I will use them again and refer them to my friends. Great Job Black-Haak!

Experienced problem with a large April air dehumidifier. Request for service was handled quickly. Technician was courteous and thorough. Further evaluation was needed at the office for codes and service bulletins as well as warranty. Looking forward to the resolution.

I've been a Black-Haak customer for several years now and had many good experiences with the various technicians that have been to my home. Today I had the pleasure of meeting Greta. She was thorough and knowledgeable. She was patient with me and listened to my questions. Her answers made sense and were clearly worded. I am not a technical guy and she explained it to me in such a way that i understood. In addition she brought to my attention a solution for an issue I've been wrestling with for several years regarding some piping and venting. I previously had two contractors in at different times to try and fix the issue and neither was successful. She provided the most sensible solution I've heard to date, I feel like I'm on the right track to fixing this issue. Thank you Greta.

Evan did a fabulous job at talking me through the process as to why my house wasn’t cooling down and what he was doing to fix it. He was professional, quick, and detail-oriented. I called to have someone check it out and within an hour he was available same day to come out. Thanks!

Our 27 year old A/C system stopped working. I called Black Haak and they sent the senior tech out to look at the system and recommend a replacement. Between the discounts offered and the 12 month free financing, the had the best deal I could find. The techs arrived the next morning and had the new system installed and working by 11:00 am. I would recommend them to anyone needing furnace or A/C work done. They are friendly, knowledgeable, and skilled.

I live in Tennessee and my 90 year old mother lives in Appleton. She was having issues with her electrical. I had Black-Haak service the electrical panel and repair 2 switches in the bedrooms. I was extremely impressed with the professionalism of Mike and his helper Isaiah. My mom felt very comfortable and respected. We were informed when, and who was coming with a picture of Mike for identification before he arrived. The office personnel was polite and helpful setting up the appointment and had excellent follow through. Thanks so much for your great service!Pamela Allar

We had a problem with our a/c on a Sunday afternoon and called Black-Haak. They had a service tech here within an hour and they had our a/c back up and running in no time. Our tech was very knowledgeable and Black-Haak provided information on what precautions they are taking related to Covid-19. We highly recommend Black-Haak.

They did cancel one appointment which caused some inconveinance on my end. Other than that I was very pleased with them. The electrician was very nice and did a good job, going above and beyond to make sure things were right and complete. They followed up to make sure all was good.

Black-Haak was great to work with. They were able to schedule an appointment within days and I had an estimate within hours. They have great communication. I received a text with the name and photo of my technician Mike. Mike and his crew were here for most of the day working. They showed up on time and took care of everything. What impressed me most was how Mike and his crew interacted with my family. They were kind and patient with my pets and my kids. Thanks Mike!

Our air conditioner died on a Saturday during one of the hottest weeks of summer. I called Black-Haak in Sunday, they got an estimator out on Monday morning, and I had a new A/C installation scheduled for Tuesday. Then, on Monday afternoon they called and said they had an opening and could get the new A/C installed that day! They got the new unit installed, and their techs stayed even longer to fix a shorted out wire connecting my smart thermostat to the new unit. The experience overall was excellent - very professional, responsive, quick, efficient service all around.
