Reviews
Jesus was clear, took time to ensure all basis were covered. Efficient and economical. Will add to speed dial!
Work quality is great, but I’m still waiting for my receipt and warranty for the work done still haven’t received it!
I was impressed with the manager Jack. He really cares about customer satisfaction and company reputation. Would give business in the future.
Overall satisfactory except price seemed really high. They did upsell us a new unit but ours was almost 25 years old Not use to today’s prices I guess. They did help us work out financing. Very responsive. Done in three days during big heat wave. Polite people to work with.
Original review posted on 7/20/25. Updated on 8/18/25 - I don't agree with the work, but I am satisfied with the resolution provided by NorthStar.
I needed my AC fixed in a hurry this summer and Northstar was able to have someone come look at the problem that day then fix it the next morning. They did thorough, quality work without pushing me to fix more than I could afford. If I need help again, I’ll definitely be calling them.
Unable to retain simple information regarding a prospective job. Not worth the time, at least for me and my experience.
Performed the service in an expeditious manner along with professionalism and explained every detail of what I needed along with options
Tech came in and I explained the issue. Possible ductwork leak. Never did the tech go in the attic to check for a leak nor on the roof to check my AC unit. Just said $6500 for ductwork and $15,000 for a new AC unit. Get this, Wanted to charge me $299 for a written estimate. Obviously, north star is just trying to extract as much money as possible from you. A complete waste of time, money and effort. Stay away. On a scale of 1 to ten, a 0.
Great Team!
I didn’t hire this company for 2 reasons: 1) I felt uncomfortable with him asking me if I was the homeowner and 2) I felt like his pricing was astronomical for the simple job it was (tankless water flush). I feel like I may have been up-charged because I’m a woman and he figured I don’t know better. He quoted me $199 but I went with another company from Thumbtack that charged me $140 and the guy showed me how to do it myself so I don’t have to pay someone again. It was only 40 minutes.
Wow, don't believe me. But as soon as you hear these guys you will know. Since the moment they step in your home they want to charge you more. They will ask you the classic bait questions. As soon as they look at your pipes it is...ooh, oh no. Long story sort according to them I needed a full re-pipe of my house, quoted me 26,368.00. I have the "options" sheet to prove all this. But if I just wanted my washer dryer shutoff valves and box replaced it would be 2,583.00 with no warranty no guarantee. This was on 4-2-2024. Had two more companies come out and it was $650.00 with a professional plumbing company not a handy man or any other excuse. This was apples to apples I wanted pro work done. I don't mind paying professionals for professional work. I have no doubt they will say it was different and I needed more work. Whatever a fox is a fox is a fox. Like I said in the beginning don't believe me. You will know once you hear them talk. Do you, but be warned. Have a great day everyone!
I appreciate the consultation I received. I really appreciate the knowledge and professionalism.
I appreciate the quick response and then being able to come out for in home consultation right away. They were on time and updated me on tech’s ETA. What I did not appreciate was I felt like they were price gauging me because I was a female. I looked into the cost of moving a gas pipe before hand so I had an idea it would cost me $300-1500. They quoted me $2400 and it did not include drywall repair. I got a second opinion the next day by a reputable plumber and got a price of $400 which includes drywall repair. That’s a big difference, needless to say I did not hire them to complete the job.
Excellent customer service. Knowledgeable on all facets of plumbing. Wonderful experience!!!
Had the best experience with and gained knowledge. Will definitely recommend.
I highly recommend Northstar. They followed up on the technician arrival, he was friendly, professional and did a great job.
