Black Haak Electrician

Generac Generator Purchase & Installation

Our experienced team of electrical contractors will answer any questions you may have about purchasing and installing your Generac generator system. Your generator will be installed by factory authorized technicians quickly and efficiently. Likewise, our electricians install high quality Generac systems made in Waukesha, WI, which run off of liquid propane (LP) or natural gas.

Typically, we install an automatic standby generator to back up your electrical system in case of an outage. The system is hooked up directly to your home’s electrical circuit breaker box and if an outage occurs the generator automatically turns on and supplies your home with power until utility power returns, then shuts off, and is on standby until the next outage.

To get started with your Generac generator system purchase and installation, please give our experts at Black-Haak a call today at (920) 750-7138.

Gary was very professional and answered all of our questions. He was thorough in his inspection. Found an issue and addressed it right away! We have had Black-Haak replace our furnace and our A/C this year and highly recommend them!

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.

Gary Petrie did an excellent job on the start up of our new furnace at both of the duplex's today. Such a pleasant person to have as one of your employees. I wish there were more people out in the workforce like him.

I just had Gary finish up with my annual furnace inspection/cleaning. I recieved a call 30 minutes earlier than my appointment to ask if he could show up early. Very thorough tech and very relatable. Great job from a great technician!

We really like having Dan come to our home to check our furnace, he is very knowledgeable explained why our furnace need to be replaced and was timely with an estimate. Unlike many other contractors, they return calls quickly and arrive when they say they will. Scott, the technician that performed our new furnace, A/C, and piping installation was friendly, professional, competent, and efficient. I appreciated how carefully the service personnel treated our home as they went about their work. The staff is knowledgeable and willing to explain or answer any questions. Every experience with Black-Haak has been excellent. We recommend them without reservation.

So very thankful Generac provided me with a very reliable company to get my stand by generator fixed. Called them this morning and they were here within an hour. My generator has been out since the July storms hit our area. It was a very sick feeling to have my stand by generator go out within 3 hours of the electricity going out. Have been dealing with another company to get it fixed from 2days after electricity went out. Just given the run around. Very reassuring to know there are still reliable companies that care. Within 1hour Mike Williams had my generator up and running. Thank you Mike. Only bad point, my warranty expired on May 29. I would recommend this company to everyone.

Very communicative, almost to a fault with redundant emails, texts and calls for appointment reminders/updates, but better communication than other services. Work was done well but could have been better. They do take pride in their work so if it's not up to par the first time, they'll get it there. Friendly as can be throughout the process. Average to above average pricing. Happy to have had them install hvac add-ons for us.
