So if you call them for an appointment ask first if they have the tools to complete and the time. Michele Goodwin

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.
