Smith and Keene review: Bad or no service when called

I had a brand new trane air-conditioner installed. Made a big mess and had leak upstairs. I had them come back 4 times before everything working and they fixed the ceiling that was leaking from pipes from air-conditioner. Had them check air under the warranty the first year no problem, then the 2nd year under the 2 year warranty that they had. They came JUST TO LOOK AT AIR_CONDITION, but for some reason they started checking the gas furnace.

Said the heat exchanger was bad. They ordered new one and charged me $700 to put in. (i told them they weren't here to check my furnace). They shut down the unit told me for safety reasons so i had no heat during a week in the winter, that's when all the trouble started. They installed it, didn't work right, had them come back, and come back and come back. I decided to pay someone to inspect unit and wrote up a whole list of things done wrong. Installation foam that should have been around the unit was laying on the floor. He said it looked like someone tried to fit a square into a round hole. My son-in-law called to try and get them back here, they never returned his calls.

Heating system shut off now its summer, still trying to get them here. Now my air conditioner is acting up intermittent. Today couldn't get it started so called another company to look at it. 90 outside 85 inside. He looked at it and said exactly what the inspector said. And more the unit had now fallen over and was crushing on a air flow causing the air-conditioner to freeze. He said it was in serous condition and dangerous. My son-in-law wanted to get Smith and Keene to fix it. But honestly don't want them in the house again. Decided to buy brand new unit at a cost of $3, 500 which i really cant afford. I am a widow and i think they just took advantage of me.
