I will continue to rely on their service!

Our fault?????? They returned and fixed the issue but we're charged $75 dollars for the first 5 minute visit that was rescheduled due their issues. How is that right????? So if you call them for an appointment ask first if they have the tools to complete and the time. Michele Goodwin

I called around 10:00am on a Monday, and their customer service rep Jessica was so very accommodating. She set up an appointment for 2pm Same Day! Their furnace specialist Chad showed up right on time. They charge $90 an hour plus parts. I thought this was going to cost me a fortune, however Chad got to work right away, found the problem immediately, and installed a new blower motor (this was our issue) within an hour! Chad was not only time efficient, he came ready with all of the necessary tools for any job as well as furnace parts in his truck! We have an older furnace so I was Very impressed that he carried all of the necessities for any furnace in the back of his pickup! The part prices were VERY fair and so was the hourly labor cost given these guys get there and get the job done right and done well. I would absolutely recommend One Way Service Pros to anyone. They are local and a business that truly cares for their community. Thank you One Way Service Pros! I don't have to worry about my family freezing tonight!

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.

Their pricing and billing is beyond understanding. When I questioned their billing I just got another bill for $10K. Horrible service. Never followed through with anything to the end.

My system still does not work and they refuse to work on it unless I paid more money. Now I am having to hire one of their competitors to finish. Very unsatisfied in all respects.
