My water heater went out unexpectedly, a water heater another plumber told me only 2 months ago…read moremight need to be replaced in the future but I had at least a couple of years left on it. I began shopping around for quotes, and was ignored or - in one case - told they wouldn't work on it "but good luck". We have an older manufactured home that we're trying to keep alive just long enough to build our forever home, but that still requires the occasional repair and all we seem to run into are people who tell us it cannot be done. Our house is too old. Our equipment is too old. Nothing can be repaired. Sometimes we can't even get people to show up and replace them. Then I met Alex. We discussed multiple options, and we decided to upgrade to a tankless given that the old water heater had apparently been leaking - a fact that the other plumber had apparently completely missed. Not only that, he was able to diagnose an issue with our furnace that will allow us to give it a much needed repair for far, far less than we were quoted. (Originally we were told we needed a full replacement as parts couldn't be ordered for it. He immediately found the part and it's cheap and easy to replace!) Alex treated us like people, listened to us, helped however he could, and even when parts didn't fit he worked tirelessly to get replacements immediately. He was always customer conscious. He's not only earned loyal customers for life, but we already have other jobs lined up for him. Honestly, I'm just grateful there are still people out there operating with this level of integrity.

This company is notably undervalued on Yelp. I would award them ten stars if that were an option. I…read moreinitiated contact via Yelp, and they responded to my residence within 90 minutes, promptly restoring full functionality. They provided a comprehensive overview of the issues affecting my system, which led me to decide on a new system installation. They commenced the installation at 7:30 AM this morning and completed the work efficiently, leaving me no opportunity to offer them lunch. I firmly believe this company merits a five-star rating. Prior to engaging their services, I reviewed their ratings on other platforms and found them consistently near 5.0 across all other applications, with the exception of Yelp. Therefore, I can confidently state that they are underrated on Yelp. This has unequivocally been the finest service experience I have had in a considerable time.

Service technician was good and very courteous. However, when it comes to charging for parts and…read moreservices, this company uses deceptive practices. On the most recent visit, they attempted to charge us for parts that were under warranty. Once they were called out on this issue, it took days to resolve and at final resolution, my cost was still at 65% of the total bill. This cost was strictly for the installation of the single part which took 10 minutes (the initial visit was covered under a service contract). When challenged, they stated that the remaining charge on the bill only reflected the installation of the single part. I call it "smoking mirrors!" Outrageous!

We have used Dave Erzinger's services for our home's heating and cooling needs for many years. We…read morehave also entrusted our church to his services. In this day and age where customer service is hard to come by, Dave is a shining example of how a business should be run. He promptly returns your call, arrives when he says he will arrive, quickly acts to diagnose and repair and his prices are fair. He has replaced our air conditioner in the past and our furnace as well. I highly recommend Dave Erzinger for any of your heating or cooling needs. He is honest, highly skilled in his trade, reliable and trustworthy.
