Services
We're always looking for new team members who share our commitment to teamwork, professionalism, and individual responsibility. There are multiple companies offering "3D Laser Scanning" in the area, but nothing near the level Williams is providing. Williams owns and operates the Trimble TX6 (the only one in the state of MT).
Williams + Harvey's is a vertically integrated mechanical engineering and construction company, which allows us to operate differently than a traditional engineering firm. We offer services for the full life cycle of a building, from design and engineering to HVAC, hydronics and plumbing installation.
Using BIM, we take the process of generating and managing building data to the next level by ensuring the model works through preconstruction, construction, and the lifespan of the project. As construction schedules shorten, BIM becomes crucial in coordinating trades and prefab assemblies to accommodate modern day construction timelines.

After trying a few, this is the best shop in town. Super impressed with the whole Williams team. Service is fast and responsive, straightforward techs who care about their work. Grant and Jesse have done great plumbing work for us (remodel, emergency drain work), and Brodie helped problem solve a tricky kitchen exhaust install. Highly recommend.

Positive: Punctuality, Responsiveness
I called three other companies. One couldn’t come out until Thursday and the other 2 didn’t call me back. This company answered the 1st time I called, scheduled a next day appt. and followed through on when they said they’d be here! I’m so impressed.... they even took before and after pictures! I will definitely use them again.

On 11/11/20 I had a appointment scheduled with another plumbing company that forgot about my service. My next call was to Williams Plumbing. I was definitely flustered as I had waited for over a week with the previous company. I even took the whole day off to make sure there would be no hiccups. A very long story short Williams plumbing saved my bacon. Within 2 hours they were at my house and had the problem fixed within an hour . They were very happy to help and very responsive and kind. With service and integrity at this level they will have my business for life! Thank you Travis for what you

We have used Williams Air Conditioning and Heating since buying our house in Goodyear 3 years ago.They have always did a great job and always gone above and beyond. I hope if anyone needs their Air Conditioning serviced they will check out Williams Air Conditioning and Heating they are very reasonably priced.

Williams Plumbing had installed our heating and plumbing when we built our home. I called them out for yearly maintenance on our geothermal/heating system. We knew the geo was not working properly based propane consumption and heat pump values. Tech, Doug, did maintenance service and indicated that we replace flame sensor, igniter and clean heat exchange in the spring. We did not want to wait since it is winter and we wanted geo system working. While scheduling this service, we signed up for their yearly service contract because it would give us a discount on services plus other extras for

I've used them twice and both times I've felt ripped off. First time had them replace a couple of pieces of pipe for a home sale. The rep spent most of the time talking and wasn't there for 45 minutes. Charged me for 2 hours and said their trip there and back counted. There office is less than 15 minutes from my home. Next time new house. My radiant heat system not working properly. Rep said that it was a faulty valve. Replaced it and charged me $700 to replace it. I could have bought the valve for under $50 at the local plumbing supply house. He wasn't here even 2 hours. The

I have had terrible experiences with Williams Plumbing & Heating in Bozeman MT. I have a crawlspace that every Spring gets several feet of water (ground, large amount of snow this year). They sent a "technician, charged me over $2000 in last two years, and I as left with continued flooding of my crawl. Specifically they installed sump pump with an exit/discharge pipe of 1 and 1/2 inches diameter,and connected it in two places to a 1/8 inch metal washing machine discharge hose. THIS DID NOT MOVE THE WATER TO OUTSIDE of my house at a rate that prevented flooding of crawlspace. What

About a month ago I wrote a review and was unhappy with the price of two kitchen disposal units that were installed. The work was done well but I felt the price was too high. Since that time Ive been contacted by Williams and there was a mistake in the billing and so the corrected price was lowered to one that fits the work done. Ive used Williams for over 15 years and have always been very happy with the work. This restores my confidence in them.

I'm looking to get some fairly significant work done ($4k+) so I contacted Williams via their email address and I contacted them via the form on their website, both with detailed messages - never received a response to either.
Not acceptable in this day and age, looking at the other reviews here I've dodged a bullet.

Absolutely awesome!!! I had a mess ... needed bath tub completely hooked up, laundry room installed, kitchen sink connected, bathroom sink re-plumbed, and hot water heater fixed. I had three plumbing companies come out and provide quotes ... Justin from Williams Plumbing was the only one who truly listened, did not try to up-sell and thoroughly explained what was needed to properly do this job. After this meeting I was completely confident in Justin's knowledge. Booked the job, Justin did a walk through with his crew to explain exactly what was to be done ... Derek and Mike were clearly experienced
