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.

Service was good but my only concern was scheduling. Had to be changed to a later date and the day of service, tech arrived 15 min late. The office called and alerted us so that was helpful. I'm wondering if you prepay for the ac tune up when you pay for the furnace tune up in fall that kind of puts you as a lesser priority to get on the schedule.

From Rick at the time of the estimate to Devin and Jeremy and the others at install, top notch service! They were not the cheapest estimate but were in line with their competition. The information and service were the reason we chose Black Haak for our central air and we have no regrets. Thanks a million guys! Job well done.

Jamie has been great in reviewing options for replacing our furnace. The technician identified an issue with our fan and given the age of our system, recommended replacing. Jamie arrived within 30 mins of the technician leaving and reviewed options with us for replacement and provided a quote for a new system.

Anytime I call for a heating/cooling question/issue, I get an immediate response. Non-emergency issues are usually addressed within a day or two and any type of emergency is handled immediately!! Wonderful company. Awesome, friendly employees. SO glad they were recommended to us a couple of years ago. I wouldn’t go anywhere else!’

They were able to get me in early and called to let me know - appreciated. The technician, Dan, was wonderful. He was very friendly, knowledgeable, loved my cat (bonus points) and patiently answered all my questions. I would 100% recommend both him and Black-Haak Heating to others!

Fantastic experience with everyone at this company with the replacement of both our furnace and a/c. Rick in sales was fantastic to work with - responsive, not pushy and very knowledgeable. Craig and Adam did the install and no complaints whatsoever! They were efficient, knowledgeable about the products they were installing and very professional. Cleaned everything up as if they were never here! Highly recommend for your furnace and central air needs!

Kody repaired my in-floor heat system today. He was professional, got the job done quickly, and the cost was less that I had expected! He even took the time to explain how the system works which was so helpful. I’m very happy with this company and will have them to do my heat/ac maintenance and some other work in the future. Thanks!

I had some new gas lines run throughout the house for new appliances. The two technicians that came to do the work were super friendly and helpful. The added lines were discreetly placed out of the way and looked very neat and clean when they finished. They were very thorough and made sure everything was correct before they left and encouraged me to call if any issues came up with the work they completed or work previously completed in my house. Excellent customer service!

I’m a first time homeowner learning about the home and the systems/ maintenance and how they should be operating properly. Evan was a very professional service technician who explained everything clearly and showed me on the unit exactly what he was referring to. They discuss everything with you in advance of performing any service and even waive fees or provide discounts depending on what you need done. I was very happy with my first experience interacting with a service company like this, and would definitely recommend them to anybody.

Great experience. Our heat went out on one of the coldest days of the year and they were there in a matter of hours! Great customer service and knowledgeable service technician. They even send out a picture of your tech so you know who to expect for service. Could not be happier with service.

Dan is extraordinary! Loves his job. Black-Haak has installed our air conditioner and furnace and done annual inspections for years. I can’t imagine trusting any other company with such important investments.
