"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

For years TruBuild has been making peoples dreams a reality. No job is too big or too small for us! We do everything we can to make sure our craftsmanship and communication beats our competitors. We are a family-owned business and will treat you like our family every step of the way.

"We hired Cain to do work in our basement in November 2024, in January, he informed us that they were not doing any work any longer and the money we gave him as a down payment would be returned in a few days, it is now April and we have not seen those funds returned. We have found out since that he has a history of taking money under one company name, then stopping after he has your money and opening a new company name. We will be filing a claim against Cain and his companies to recover the money he has taken. We have contacted him many times and not received any response from him. This is a buyer beware company. I would look for someone else before working with him again"

We have extremely competitive pricing, excellent service, quality products, years of experience and our committment to our customer satisfaction.

We offer a complete line of high effeciency furnaces, air conditioner and boilers that are Energy Star rated. Our air conditioners us Puron refrigerant which is a more environmentally safe product.

"I would recommend getting quotes from other companies and going with them. I had my AC replaced and they guaranteed the work. My system kept failing and I would have to keep calling them over every few months to service it and the charges kept pilling up. I contact another company and they were able to fix it for a fraction of the cost (about 10%) and we have not had any issues for over a year. Thielmann group seems like a bunch of inexperienced people that try to milk you for money. I complained and someone from the company called me directly and was very aggressive and unprofessional on the phone. Do yourself a favor and find a different company for your needs. I regretted going to them. My family suffered on several hot summer days and cold winter nights because things kept failing."

FAQs for geothermal heating or cooling system installation projects in Watertown, WI

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.

The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.

Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
