They showed up Wednesday morning to bid the job. The salesman Skyler was very good at his job. He said they could install it same day. We did the financing and the installers were there by 12:30pm. The technician told me he couldn't do the cold air returns in the basement in the walls. He wanted to install one in the ceiling of my master bath which I refused. I asked if a permit had been pulled and he said he was sure they had. He installed the A/C and started on the furnace but didn't have it working and left at 9pm. It was 46 degrees that night. The next morning I called the sales man and complained so he said they were sending a more experienced installer. 4 technicians showed up at 9am. They again said they couldn't do the cold air returns in the walls again. They ended up ripping out the whole furnace, line set, and wiring then reinstalling everything. They got it up and tested the heat and cooling once and then left at 5pm. The A/C ran all night and never met the set point (72 degrees). In the morning I raised the thermostat up so the a/c would shut off and it immediately started getting hot in my house. The thermostat was not calling for heat but the furnace was on and lit. I moved the thermostat down and the A/C came on but the furnace never stopped burning. It had run all night with the flame bar and the A/C both running. I shut it off and called them again having to leave a message. In the message I mentioned I didn't believe they had pulled a permit so I would be calling the planning office when they open. I called the planning commission and left a message. Skylar called me back saying that the permit had been pulled and they were sending someone out. The planning office called me back and said they had just asked for the permit on the 2 days after the install started. They came out about 2:30pm finished the heat runs and found they had wired the humidifier wrong but didn't have the part to make it right. They had to come back on Monday to install the part to get everything working correctly. Nothing is plumb or level on anything they installed. The inspector came on Tuesday and failed the inspection. So they need to come back and fix the minor then the inspector will need to come back. My time is obviously of no importance to them. While filling out my rebate paperwork I noticed a discrepancy. Their invoice shows a part number for a 3 ton compressor but the certificate is for a 2.5 ton compressor. My house is 1900sqft. It doesn't matter what calculator you use 1900sqft = 3 ton. Now they claim I asked for a 2.5ton which I did not. I saw 3 ton on the bid and the invoice but that is not what I have.
