Got several bids and Keith was right with the others but Keith was by far the most professional and explained everything very thoroughly. Very neat install and he combined our humidifier drain with the AC drain hose into one...neatly installed. Only bummer here is that I could only give Keith and Co. 5 stars as they deserve 10 stars.

We called them to look at our furnace, they were honest about the cost to repair and the cost of new. We chose to go new because the furnace was older and we knew we would have more problems. The costs were explained up front, we knew the start date, plans were made. On the day of the install, the men came in, put down plastic runners to protect my floors from their work boots, and did the job with a minimum of disruption to my day. Then they hauled all the old furnace and trash away. You couldn't tell that they had been there, except for the quiet hum of our new furnace. We highly recommend them!

The lady at the S. Beloit location (Char or maybe Carlene), is extremely rude. She is rude on the phone, it is obvious she is not happy, and you are beneath her ( wasting her time). She is not very accommodating when you ask her a question, acts like customers are a bother and more. I have gone in to purchase a filter, my husband has gone in, and I know of other customers who have been subjected to her very poor customer service. Do your self a favor, order your filters off Amazon, they are cheaper and you don't have to be treated terribly.

He fit us into his busy day to come help us out. We had an unknown problem with our furnace and he was able to give his opinion of what the problem may be. Greg came out and I brought him down the furnace. He offered to have me watch what he did so that I could maybe gain some know-how. Greg worked quick , and as someone who enjoys learning he was more than willing to educate me on what he was doing , and why he was doing it. Greg further educated us about heating and cooling in general and gave us some tips and advice. It was a cheap service call and he got our heat working again , what more can I say. Professional, friendly , courteous. Will absolutely hire again.

I had two furnaces installed roughly 15 years ago. They worked fine. The price was reasonable. I…read morecalled them back recently And they didn't show much interest. I got no consideration as a former customer for repeat business. I guess my heat exchanger hadn't been registered Or something to that effect. If it wasn't registered at the time This stated warranty will not be honored. I thought my contractor let me down I thought they should have seen to it instead of expecting me to do it. Putting a new furnaces is a highly distracted Consumer experience And with the amount of money involved the contractor should be taking this responsibility. I tried to give him more business but I was just treated like they treat everybody else so I had to go to a different contractor. It's hard to get good info but people should check BBB and check datcp State of Wisconsin consumer protection. That's about all you can do because just about everybody's out to screw you one way or the other. You know unless you know somebody personally.

I explained the problem. He checked the programmable thermostat, then the furnace, did an electronics test and found some part malfunctioned, a solenoid, I think. He showed me the electronic test and I saw the failure register. He retrieved a new part from his truck, had it installed in less than 15 minutes, rechecked the system and performed another test and pronounced my furnace as being cured...for now. WHAT?? Yeah, he informed me this was usually the part that failed a majority of the time and based on what I briefed him on, he had a pretty good idea what the problem was. Anyway, he cleaned out the dirty furnace, buttoned it up and wrote out the bill. I paid him and he was gone - all in just under an hour....and the house was warming up. Yeaaa!
