We needed to replace a cast iron baseboard along an outside wall in our bathroom. The base board…read moreunit developed a leak and needed to be replaced, so we called Santos Mechanical. Immediately they told us they could replace the baseboard. They provided us with several options. After choosing a baseboard, Santos Mechanical quickly ascertained the parts, removed the old unit, and replaced the new unit and parts. They worked efficiently, maintained a neat working environment, and completed the job with functionality and an excellent appearance. In addition to the replacement of the unit, our entire system had to be drained. After completing the replacement Santos Mechanical had to refill our entire system which has two different phases. They had to be in our entire house where they carefully moved furniture when necessary. They were very careful to cleanup as they went from room to room. They are very trustworthy and considerate of our home. The price was very reasonable and the estimate reflected the final costs of the entire repair.

Reliable, hardworking, honest, qualified, flexible, and affordable! Santos has shown up for my…read moreplumbing needs/ issues on multiple occasions and has always been able to resolve them promptly. He's great with communication and quick to respond. He's our trusted go-to HVAC technician.

This company is awful! i would give NEGATIVE STARS IF I COULD! I called for a quote for services…read moreand after they finally came out while I was working they just fixed the problem in the sewer out front. Then they demanded I pay them for fixing something I didn't want them to fix. I had multiple other companies coming out for quotes yet these men felt entitled to just do what they wanted. This was in the street out front of my house and not inside my home. Then they claim it was emergency services when it's an issue I've had for years and was never an emergency! A bunch of liars that scam people!!

Bartman Plumed our house 45 years ago; we didn't have to call them again for 45 years. That isn't…read morequite true; we pumped our well dry 25 years after our house was built and the submersible pump needed replacing. That second pump lasted almost 25 years, but a spring leaking into the well caused sediment and another failure that was not the fault of the submersible pump. So now we have a pump that'll last the rest of my life (I'm 72 years old). Neither service call was an emergency since I was able to reduce the pressure and get by untill they arrived. Five years ago our 20 year old control box failed. They came immediately for that... at 4:30 PM. They were prepared to pull the old pump... at 4:30 PM. You can't beat that kind of dedication to a customer. Bartman keeps up with current information (had me set the pressure higher since the manufacturer recommended it; used a two wire pump this time since labor cost and reliability are better). They installed our second pump while we were away and left the control box for me to install. They could have billed us for a visit to adjust the pressure, and scheduled another visit to install the control box... but they don't work that way. Knowing their customers has something to do with that, but we know and trust Bartman, and they know and trust us.

Beware if you choose to use this company for your plumbing and heating needs!…read more I am glad that I didn't let Gehringer steal 17k out of my pocket for a new heater that I did not need. Sorry Gehringer, you couldn't get the 17k out of me, but maybe you will have better luck with other customers going forward! Facts: Gehringer Mechanical came out to clean my heater as they did in previous years. Upon paying the bill the technician mentions that I have a CO leak and need a new heater. The technician did not provide any back up data to his findings to show me. (Nor could they provide any when I asked for it). Luckily for me, I decided to get other opinions from other heating companies only to find that Gehringer lied to me. I had no CO leak and my heater was fine. Was Gehringer really trying to try to sell me a heater? When I called Gehringer to confront them on the findings, they were trying to find excuses! I demanded that they send me out another one of their technicians free of charge to prove to me that I really need a new heater. When their second technician came out and did the testing with the meters, everything was fine. NO CO leak and I was told the heater was good and safe to use. They even sent their equipment for testing to see if calibration was off, and as I expected it was fine! There is no explanation as to why the original technician told me I needed a new heater. I was also told that they will not hold their employee accountable for this, because he is their best technician! If this is the best your company has then you don't have much of a company in my opinion. Seriously, do you really want to have a reputation as a dishonest company? Gehringer claims this was just a simple accident. I am not sure how they can call this an accident. Your technician intentionally told me I need a heater knowingly that I did not. I am not sure this qualifies as an "accident".
