We had them replace our heating and air conditioning system. Also added a new humidifier. The high efficiency unit is working great. Friendly knowledgeable and efficient. Cost was about what I expected. read more

I feel like I got lucky that he did not show up... Back in July, my AC stopped. I have home serve. They set me up with Foltz and sons. I got a text from Glen and in our conversation he set a 9 AM appointment. That was it, he didn't show up, didn't answer phone or text. I contacted home serve at least 7 times and on one occasioned (About 2:30 PM) they called him and said they spoke to him and he would call me directly to update me on when he would arrive. He did not call. At 3:30 PM I made my last call of the day to Home serve and canceled the appointment with Foltz and sons and I canceled the cooling contract I had with home serve. I got zero for my money. To this day I think I got very lucky that he did not show up especially after reading the reviews. Yesterday my furnace refused to start so again I called Home serve (I have a heating contract with them) and they set me up with Foltz and sons. I called immediately and told them about the last time and I told them they cannot send him to my house. He is not reliable and I made sure she made a note on my account. They sent my request to Action Mechanical who set my appointment for 2:30 and at 2:15 my technician was here and the problem was solved and with that fix the AC now works too. Again I got lucky the day Foltz and sons did not show up. Just save yourself a shitty day and don't call the man and always refuse Foltz and sons if you use a service like home serve, you can request another company. read more

If I could leave negative Stars on a review I would on Foltz n Sons Electric out of Spearfish. Its been cold and had a call in and they accepted the job but never received a call back. I knew I was having problems so I finally called someone else after waiting 3 days for Folz n Sons Electric to call and no call back. After I got someone thru MDU they checked it out . My carbon monoxide was up to over 2,000 ppm. I could have died thanx to them. WOULD NOT RECOMMEND THEM IF MY LIFE DEPENDED ON IT.Oh wait my life was !!!!! read more

Requested assistance for a whole-home electrical arrestor. Unable to complete, but was able to resolve as needed. Would recommend.
