  Back in December 2024 I had my gas valve replaced by Black-Haak. They came out right away with many notifications, got the job done without issue, and they offered me a free cleaning.  I took them up on the free cleaning a year later in December 2025. The same technician was back again, she said it was fine at the moment but noticed a potential crack inside that could cause me issues in the future.  Now March 2026 I noticed that the furnace did not prove ignition a few times so I went to look inside the panel and noticed that this black rubber gasket was not it the place.  The flame inside was very orange and when I would push the gasket against the hole it would go back to a nice blue flame.  So I called Black-Haak to let them know that the technician had accidentally left this gasket out.  The receptionist told me that it would be $99 to get someone out there to fix this. I told her the situation again and explained that the technician had left the gasket out when they did either the gas valve or the cleaning. No one else had ever touched the unit.  If this was work that I had done but not finished, I would run right over and get it done. Unfortunately this receptionist instead told me that it was not under warranty. I put the gasket back where it should have been myself and now I will be looking for a HVAC contractor with integrity.

  We had some issues getting our bathroom fan and light on and Jonathan was able to make it over the next day in the morning to get everything sorted out. He was very professional explaining what was going on and what he was going to be doing. He was friendly and got the job done in no time. I was very satisfied with the service, I will definitely be calling black Haak again for any future services I may need.

  John Burkhart Jr was my plumber. He was very knowledgeable and has years of experience. John took the time to explain the issue and gave me my options. I'm very happy with the service repair and it was done the same day! Highly recommend this locally owned company. Support our local businesses 💯

  I had 2 separate plumbing problems in one day! Each of the 4 gentlemen who came out were incredibly helpful.
Esteban and Cooper were phenomenal! All things fixed in no time!
The middle aged Navy Vet with Cooper was a wealth of knowledge. Thank you and your son for your service!🇺🇸

I paid more than I expected but they were there quickly!

  Had an issue with a toilet not flushing properly. Went to website, which was extremely easy to navigate and schedule an appointment. They followed up with a call shortly after, offering to have someone come out same day if it worked for us(this was a Friday). The person I spoke to on the phone was knowledgeable and super helpful.

Mario arrived a couple hours after my initial call. He was polite, courteous, professional, honest, respectful, and clearly knowledgeable. He had our problem figured out right away, and his explanation was perfect for me to understand. He then gave me options for a solution, which all made sense and were perfectly reasonable. I was also able to also get his thoughts on another small plumbing project we are looking at for our home.

Service charge, in our opinion, was perfectly reasonable and we had zero issues paying it. We are probably going to end up saving that amount, or more, due to the advice given to us anyway.

We will absolutely be calling Black Haak for future plumbing work. 100% satisfied and met all our expectations. Every single person I dealt with was amazing. To me, Black Haak is a "treat the customer well and do quality work to get customers" type of business.
