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.

I was very pleased with my furnace maintenance check. Dan and Connor were very nice. They took the time to explain all that they did and what they saw regarding our older furnace. They took pictures of inside the furnace and then sat down with me to explain the good and the bad. I would highly recommend Black-Haak.

While having our boiler tuned up for the year, the technician discovered a small carbon monoxide leak. He sent his supervisor out immediately. By the next day, we had our boiler replaced. Installation only took a few hours and there was no disruption to the household. The crew worked quickly and were extremely qualified. The office manager helped us out by taking care of all the details with our home warranty insurance provider to submit replacement as a claim. We highly recommend working with Black-Haak Heating.

They did a maintenance on the furnace today and were very cordial and professional as always. They seem happy to explain everything and, as far as I know, do a great job.(This is from 11 months ago.. don't see how to add a new review).They did our A/C last year and our gas furnace this year. Went out of their way to correct some faults of previous contractors. They have been prompt and courteous. Early days, but as far as this lay person can tell, they did a great job. They seem better than two previous HVAC contractors we had used.Did maintenance yesterday (10.31.2019)... as always did a great job explaining what was done and why. Btb, so far so good with both heating and cooling systems they installed a few years in now.

The customer service is amazing. On the day of the appointment, I received a text with picture from the service technician when he was on his way. Dan was super polite and friendly. He was also efficient and answered my questions. Then a follow up phone call the next day from Black-Haak to make sure all went well or if any questions had come to mind. This was my first experience with Black-Haak and I will call them again.
