"They were professional and courteous. They explained what happened to my old water heater and if it was repairable or not. He gave me options and time to decide. They are also military friendly. Great job Hoosier plumbing."

"This happened on Sunday. Response was excellent and technician was knowledgeable and very helpful and thorough. His name was Austin. Price I can’t really judge—since I wanted it fixed (replace water heater) immediately I didn’t shop around."

"Said I needed to approach city or county about repair as it was their responsibility (water run-off drain); suggested I might even need to involve the Mayor's Action Committee (implying he didn't think the county/city would "get around" to the job without taking it to the mayor.) "Oh Good!" but probably helpful, knowledgeable advice!"

"Jack and his helper showed up at the correct time. Jake was super smart on my plumbing project, that consisted of removing my old Water Heater and installing the new one I had purchased., and doing whatever else he had to do to make it fit. Jake and his helper did excellent work and cleaned up everything after themselves!!! Excellent job!! Both were very nice, polite young men!! THANK YOU!! Martha (Marti) Gonterman"

"I think it was fine. Actually, my wife coordinated that one but I don't think we have any problems with it. I'm not sure if we paid extra charge aside from the deal because  I wasn't at home when the guy came out to do the job. We've used them before and they are the one who installed the water system in our house. I don't think they standout exemplary or horribly bad but the service that they have provided to us was what we expected."

"Per Jim I am possibly looking at replacing the blower later today. But I was so impressed by Jim's honesty, professionalism, and willingness to allow me to watch and learn what he was doing. I always research everything online so often times I can repair myself. (this one I can not) He did not charge me yet so I will update later after the next technician finishes. But the price he gave me for what he was going to do appeared to be very reasonable for that repair.

"Our heat pump needed to be replaced and our furnace wasn't as efficient as it could have been so we decided to replace it all. After a consultation Bassett recommended a system for our house that included a furnace and standard air conditioner. We also had zones in our house but because we have an open stairway (in a not that big house) they also recommended doing away with the zones. We went with the recommendation and that first winter (last year) our house was so cold in the winter months. We were told that by letting the fan circulate all the time it would eliminate cold spots. What we didn't realize is that they never inspected or evaluated our current ductwork. It is undulated and as a result the air that circulates is always cold. The upstairs is cold and without a quartz heater in our family room, it too would be cold. We called them back to check and we were told that it seemed to be working fine. Putting a thermometer in the register said that there was heat. Later, in this summer my husband talked to them again anticipating this winter. We were told we might want to go back to having zones. It would only cost us another $1,000 or so to make that change. 

As for installation, that was done very professionally and neatly. They were prompt and polite. I would say to do your own research before Bassett ever comes and be prepared to make a decision based on that rather than what they may recommend. If I could figure out how to put that old furnace back in, I sure would. It worked much better for winter heat than this one does."
