I called Harlan Johnson because a room at my rental property wasn't cooling and I was out of town. My wife met the technician there. He told her the two condensers sitting next to each other needed to be cleaned off, spent about 15 minutes on it, and charged $400 per unit — $800 total. Then he charged another $800 to reattach a duct that was barely loose. That's $1,600 before anyone had looked at why the room wasn't cooling. The tenant told me afterward that the duct still wasn't fixed. A second tech came out two days later, said he fixed it, and it still wasn't done. Two days after that I had to drive out and meet a technician myself, and I ended up helping him attach the duct — I was the one handling the putty. He then told me that should fix the room not cooling. I pointed out that was the return, not the supply, and he said it's all the same system so it would be fine. When I asked about the zone dampers, he told me he doesn't know how they work, he just installs them. I checked the zone board myself: the damper for the room in question had no light while the other two zones did, and it was reading closed while the others read open. He told me those lights just go out sometimes and it was working fine. His solution was to cut the duct open and replace it. I said there had to be another way, then messed with the damper myself for a few minutes and got it working. So after roughly $1,800 and three visits, the actual problem was solved by me, in my own attic. I can't recommend them.

My AC failed last night. I called Classic ABC Heating&Plumbing at about 8 pm, when I noticed my AC reading 83 degrees, despite being set at 78. They sent an excellent technician named Emmanuel Luna . He arrived the next morning and inspected my system. He explained the different systems they have and helped me to confidently choose the best system for me. I was expecting to need a new system before to long. He fixed my system to get by for the weekend, and arranged for an installation on Monday. I was impressed with the swift response, especially during a heat wave. The great service is appreciated! K Soliday
