Unfortunately, without any notification to existing customers, the company was sold to ABC Heating. I had a maintenance appointment scheduled months ago for today between 8:00 a.m. and 12:00 p.m. No one called or texted to let me know the technician was running late. When I called, I was met with an AI phone system. After repeatedly asking to speak with a real person, I finally reached someone, but she couldn't provide any information because dispatch wasn't responding to her either. As I write this, I'm still waiting for my technician to arrive. The excellent customer service was the main reason I chose this company and purchased a service contract. This experience has been extremely disappointing. At a minimum, current contract customers should have been notified that the company had been sold and reassured that service would continue without disruption. Based on this experience, I can no longer recommend this company.

I just really appreciated what seems like an honest assessment.

The Grenz folks came, carefully looked at the unit, and said, "If it were my furnace, I wouldn't do anything. It is running the way it's supposed to." This second opinion cost me something, naturally, but it also saved me between $5,500 and $19,500 (two quotes from the other two companies). Jim seems like a straight shooter. I'd recommend you give these folks a try.

Unfortunately, our first interaction came due to near carbon monoxide poisoning. We awoke in the wee hours if the am to the lights and sirens of the fire dept arriving because our CO monitors had gone off. Seider was quick to arrived during a huge snowstorm with an emergency weekend call. The corrected a disconnected outlet/exhaust from.our boiler, and were prompt with arranging a follow up service call to correct the issue that caused the exhaust to come off. An issue with the sparking mechanism was causing gas to build up in the unit, from what I could gather. Our technician seems knowledgeable about our unit, and had all of the parts and tools he needed to diagnose and repair it. The prices seemed fair, things were explained well and a detailed invoice was provided. Despite high demand during a major storm, they were able to correct our immediate safety issue in a timely fashion. We felt well cared for, and would definitely use them again.

Addition - After Making this post, the Owner did reach out…read moreto me and apologized for the actions of some of the other employees, refunded more then half of the money, and came and fixed the electrical to that which was originally agreed to. The Owner Made it Right. Notes to the Owner: Bart that showed up today, was professional. He was Apologetic for what had happened up until this point. And cleaned up the previous mess that had even been left by Joe and Dan. This is how management should have been, and should be. Even when Ben (The master electrician/Manager showed up today) he was making excuses for his actions. That too many people message him and it's easy to forget about something. This isn't the paying customer's problem. If you make a promise to a customer, and you don't keep it, you've messed up. Original Post - If you want timely response. Don't use Seider. If you want the work done that was agreed to. Don't use Seider. If you want Employees Fighting in your house. Don't use Seider. I have had a series of interactions that left me not really wanting to work with the company. After Rude employees, unprofessional behavior, and taking forever to get me scheduled, I would recommend going to another business. First interaction was fairly strange and unprofessional. I was contacted after submitting a form, asking me to reach out to schedule service with Ben, their master electrician, on August 3rd. Upon reaching out to him, I was questioned as to why I was calling this number, who gave me the number, and didn't help schedule. I had to reach back out to the scheduling person that told me to call Ben to get it on the calendar. I had a guy come out for the initial investigation on Friday August 7th, and was told that I can call over to get it scheduled, and they will make it a priority, because the electricity was out in my bathroom. Upon calling to try and get scheduled, the scheduling person stated they would need his paper work in order to schedule me, and they would reach out on Monday. He asked me at that time if I wanted my bathrooms vanity light and the fan and heating lamp on seperate switches, which I stated yes. They didn't. I waited giving the company benefit of the doubt (Employee stated they were fairly busy). Friday the 14th of August I reached out for an update, got the run around because the scheduling person wasn't there. I had to call back again, and again, and again, before they FINALLY got back to me August 24th (17 Days later --- WOOO Priority) to get me scheduled for September 1st. The two guys that were working on my house on September 1st were shouting at eachother, calling eachother names, criticizing what and how they were doing the work, one of them threatened to stab the other, threw things down the stairs, and didn't install the vanity light and fan and heating lamp on seperate switches. I rarely leave bad reviews without talking to management, and attempted to get this fixed. They stated they would get back to me that same day about a resolution (IE, either some money back or getting the switch situation fixed.) That was September 2nd. One of the two employees (Joe) Called back to apologize for his less then professional attitude the day of, but As of today (September 14th - almost two weeks later) Management still has not done anything to resolve the issue.

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.
