I called Allstar Heating and Air Conditioning because I wasn't getting any cool air from my air conditioner. The guy was real nice and said he would make sure that somebody would be here that day. I didn't call them until after six so I really appreciated it when they showed up around 9:30 that night. It was much cooler then. They spent about a half hour trying to find out what the problem was with my unit. They said they had to flush out something and that something had stopped up and over run. They weren't sure exactly what it was that was wrong with it. So they weren't able to fix it. I will call them again to come back out. Really nice guys.
