Thielmann: I'll try to give a brief background. The furnace (unit also has AC component) in my…read morecondo was having white smoke/steam come out of the external vent during some of the extremely cold weather we were having. Even though my furnace was not making any unusual noises, smells, or setting off my carbon monoxide detector, I was still concerned as no other condos in my building or nearby buildings were having the smoke/steam. The employee that initially inspected by furnace (Carlos?) informed me that the heat exchange was clogged and would require me to repair the furnace or purchase a whole new unit (I opted for a whole new unit based on its age). Carlos gave me the impression there was no rush and that it was not something that necessarily needed to be done immediately. When the second employee (Dave?) came later that day to take measurements and verify the replacement unit needed, he made it seem almost emergent and began to wonder aloud if he needed to shut my furnace off that day. The stark contrast between the two was alarming and created a bit of a trust issue on who to believe. Carlos seemed a little green and Dave seemed like more of a veteran. Dave eventually determined it did not need to be shut off as no carbon monoxide was entering my condo. The whole experience did create a bit of a panic for me though, so I quickly accepted the only available appointment within the following two weeks. It was convenient that they could get it replaced just five days later, but if it truly wasn't an emergency then I would have liked a little more time to verify I was getting the best price as it wasn't cheap (to give you an idea this is the largest purchase I've ever made behind my home, education, and car). They do offer payment plans that were easy to enroll in, one of which has 0% interest if paid off within a year. I'm not trying to throw anyone under the bus, but I can tell they really want an honest review as I've received multiple texts and emails asking to leave one. The crew that showed up on the morning of 12/24 to install the new unit were quick and efficient. They were respectful of my property and explained the new thermostat to me. All the employees were friendly, including the ones running the office over the phone (Micah?).

Thanks to the flooding my hot water heater is shot! I called Thielmann (since they previously were…read moreRoss and that was the service I use to use) they came out to inspect my pilot light situation and unfortunately just the inch of water I had is the right amount needed to short circuit things. He also made sure to check out my furnace to ensure there weren't any issues with that - I knew the AC was working fine but he ran a service check on the heat as well. I am a little confused as to what's happening for the next appointment I've set up - is this to gain an estimate on a new heater or to actually install one which is the reasoning for 3 versus 4 star. Tried calling back to find out but couldn't get ahold of someone. I'd like to get a few quotes of course for something like that/have a discussion about the types of options for water heaters.

The call to schedule was professionally handled and on the appointed day and time, the crew, Alex, Tony, and Jackson arrived. Alex surveyed the home to count the number of vents, suggested dryer vent cleaning as an additional option, and a price was offered and accepted. Long drop clothes protected the first floor, equipment was brought in and the cleaning finished in about four hours. Within hours of their departure, my wife noticed a major decrease in the house dust. The entire project was professionally handled from start to finish. The results are excellent and the cost in the ballpark of estimated range. Highly recommend this company. James W.
