Given the symptoms, we thought I might have to replace my blower fan. At noon today, I got notice that Mike was on the way to look at the problem. At 12:30, Mike arrives. At 12:35, we're both looking at the furnace while he takes the blower fan cover off. At 12:37, he has diagnosed that the fan isn't dying or dead, but that it has shifted in its mounting bracket, making the fan blades hit the enclosure. SUPERB AND FRIENDLY SERVICE! I COULDN'T ASK FOR MORE. Honest, responsive, hardworking and friendly. HIGHLY RECOMMENDED!

I can't thank Sam & Mike enough. They showed up a bit after 8am to fix 1 leaky toilet and another…read morethat wasn't flushing well and flush the water heater. The water heater had a leaky valve, so they had to fix that first. Then the first toilet needed new gasket and seal in the tank. Then the 2nd one turned into a major project. It was clogged with calcium that they couldn't fully removed so we decide to go for a new toilet. When they took the old one out the seals in the floor were all rusted out. And the pipe in the floor was a mess so they had to replace that too. And once the toilets were done, they installed bidet attachments for us. They finished up around 2pm. I was so grateful that they were able to get everything done for us in 1 day. Highly recommend!

Where to start with these guys... first off, this review is for the Colville store, but there is no…read morespecific entry in Yelp for that store. My relationship with Northstar started when they installed the heat pump in our new construction home. The heating system was wired incorrectly, and had to be fixed by them. They left several ducts not connected to vents. This was found by me going into the crawl space, and seeing no ducts connected to several vents... A leak in the system developed, but no leak could initially be found. I was told by Norstar that the loss of 8 lbs of refrigerant was the probable result of a theft of the fluid...several hundred dollars later, the unit was working , but with very high energy bills. Norstar came back out, and again found the unit was short on refrigerant. After $400 more dollars in testing, several leaks were found. They seem to have a hard time with the long term fix of a system, and our more concerned with short term solutions (that then need more fixes in the future). They have always been friendly with me, but my wife has had mixed results with Norstar on the phone. In one example the service manager basically said my wife was lying on a scheduled appointment. It was a miscommunication in which the service manager told my wife that he remembered the conversation between my wife and I better than we did...not a great example of customer service... We do love the Lopi wood stove we purchased from them, and they did a good job installing it....but for technical repairs/assessments, I cannot recommend them. We went with another company for the repair of our system. It should be noted that there were several other negative issues we had with Norstar that were not mentioned in this review.
