Top notch, professional service…read more Seider came recommended by both our realtor and the former owner of our home. 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.

Uttke performed a diagnostic and confirmed what I thought all along--the air handler was not cracked, and there was no carbon monoxide leaking into my home. The system was cutting off because I had installed one of those "smart" thermostats that have given homeowners so much trouble. Uttke did show me a good replacement for my furnace when the time came--a mid-range Armstrong furnace. I appreciated their integrity. I went out of my way to purchase AprilAire filters from Uttke because I appreciated how I was treated. Fast forward a couple years and I had moved to Cedarburg and needed two heat pumps. I called Uttke, got an in-person assessment, and a quote. I purchased on the spot and within days I had two heat pumps installed. Uttke was great in terms of communication to make certain the units were placed where I wanted them, and where they would make the most sense. I would recommend Uttke with confidence.

I called Gross Heating on Monday to have someone come out asap. I was told Wednesday morning was the soonest they could make it. I was reluctant to call another company because in the past I had a bad experience with another. The last time Gross came out, they did a great job, so I called them back and said okay to Wednesday. They said they could actually send someone out Tuesday, late in the afternoon. The technician came out and apologized, saying this job may take more time than we have today and run into a lot of overtime. So, a new appointment was set up with another tech for Wednesday morning. In a way I'm glad this happened because the new tech was excellent in every way. He had the part I needed on his truck and had everything completed at noon. While he was there, our daughter called saying you won't believe this, but my boiler stopped working and I have no heat. Gross had anticipated the tech would be at my house the entire day. I asked if we could go over to her house to take a look at her boiler. Gross said okay, so off we went. She needed a new pump motor, which luckily he also had on his truck. In conclusion, both of our heating systems were fixed in the same day and at what I feel was a reasonable price. I trust Gross Heating and wouldn't use anyone else.
