Replacement of water softener was very professional. Very knowledgeable about the softener and tidy. Caleb is a very polite and courteous young man. We'll definitely use and recommend Thelen Mechanical to anyone.

Caleb was very professional, very quick and very knowledgeable with my questions. Had suggestions that were very well informed. Would highly recommend this company. And would highly recommend asking for Caleb if you decide to go with them. Yes, the prices are high but isn't everything these days and you get what you pay for. Very happy with my service.

I called Thelen to get a quote for some work I wanted/needed done in my house.

They sent someone out to look over everything and provided a quote at no cost. I found their pricing to be super reasonable!

I ended up getting an outside water spigot replaced, a shut off for the spigot installed, new shower trim kits in two bathrooms and a minor leak in the water main coming into my home repaired.

Once I approved the estimate they were able to get me on the schedule very quickly and gave me a two hour window - they showed up right on time. They even had to coordinate with the city to shut the water off for the repair and everything seemed so smooth.

They did have to come back to do one more thing that I was not able to be there for, but they sent me a picture of it when it was done which I really appreciated!

I am extremely happy with the service I received - from the initial call for the quote, the two service calls and every interaction I had with the men and women in the office - highly recommend and will definitely use again!

This company is so trustworthy and efficient! I was referred through word of mouth and so glad I had them come out to service my furnace fan and ac unit. So glad I decided to wait it out with the original contractor I had contacted and had Thelen mechanical come out a few days later. They were fast, efficient and explained everything perfectly! Definitely recommend!

As always the technician was very knowledgeable and kept me informed as to what he was seeing with my AC unit and what the steps would be to fix it. Extra bonus points because I recently seeded the area and the tech did everything he could to avoid disturbing it. It looks as though no one was ever out there. Much appreciated!

So pleased with my experience with Thelen mechanical! They were able to respond the same day to an urgent plumbing need and were communicative, professional, and quick.

I had another company to my house after my AC went out. The other company quoted me 12K saying my AC was not fixable. Nick with Thelen Mechanical came out and had my AC running within 30 minutes. Nick was amazing, professional, and reassuring. Needless to say, I will be calling Thelen Mechanical for all future needs!

Friendly same day service! They were honest and not price-gouging which was refreshing. Thank you so much!

Good Quality, value, Responsive, on time, and professionalism.
All of the above.
I expected to rough in a bathroom and add a bath fan on the main floor, and countertop sink on a different level, and to vent it thru the attic and out the roof on a hot day to take longer, Thelen took just 1 day with the right amount of crew to get it done. Great job.

Thelen Mechanical went above and beyond to help resolve our issue. Austin was our tech and he had great communication with us and get us informed every step of the way. I will be using them for my future needs and will highly recommend them!

Had an emergency plumbing issue on a Saturday night and after calling 5 others who couldn't come for 2-3 days Thelen had a tech to us in about an hour who solved the problem quickly. The technician was great and provided great service. Really appreciate them helping us out with our situation.

Our gas water heater died and I wanted to go electric. They were able to make it happen in a day. Got the electrician out to run the new circuit and got the old water heater out and the new one in in less than 24 hours from our call in. Caleb was very hesitant the first evening and Phil and Sam got the work done very quickly and efficiently. A great experience.
