I had previously used brinker plumbing and was satisfied with the service and cost. Since I last…read moreused them they were bought by Kotz heating so when I had a few plumbing services needed I again called them. This experience was a total disaster. The tech that was sent out refused to repair a leak in my built in whirlpool tub drain stating parts were no longer available and I would need to replace the tub. So I then bought a tool needed to unscrew the tub drain strainer and used some new plumbers putty to reseal the drain, TUB FIXED. Also needed a 3/4 inch copper valve replaced and was given a quote of $341.00. I decided that was way to high and I would do the job myself. The total work time for me was 25 minutes and $14.00 for the valve. In effect I was to be charged over $600 per hour labor by the plumber!

I've used these guys exclusively for the last few years, and I've never, ever been disappointed. Jason was even very patient with me, as I was late getting away from my client to meet him. He sat in my driveway for 30 minutes waiting for me to get home. I've used cheaper "handyman" types, and other plumbing/heating companies, but I've never been completely satisfied. These guys even do bi-annual inspections to make sure everything is tip-top shape.

My furnace started to have problems, kicking on and off. Being almost 0 degrees outside and a…read moreSaturday, I was preparing for a big bill for after hours service. I called a few places and no one had availability. Superior was my 3rd call and I spoke to Kevin. He spent probably 45 minutes with me on the phone, diagnosing the issue with my furnace - a faulty igniter. After he told me he probably didn't have one as my furnace is uncommon in Michigan (a Lennox), he directed me to a store where I may be able to find the part. I was able to find the part, and with his guidance, I was able to install the part and spent about $30 in total. This type of service may not have earned Superior any sales yesterday, but it earned them a customer for life. I will definitely be going to Superior when it's time to replace the AC, hot water heater, and furnace.

Oak Electric installed my solar system after I selected them through the City of Ann Arbor's…read moreSolarize Ann Arbor group-buy program. Overall, I've been pleased with the installation and the system itself. My concern is with the follow-up service. Part of the critter guard came loose and fell off, and it has now been almost three months since I first contacted Oak. During that time, I've corresponded with three different people at the company as well as their phone service. I initially asked whether the repair was covered under warranty. I also asked that, if it was not, they simply provide a parts list or tell me what I would need to buy so I could address it myself. I still have not received that information. I was subsequently told that Oak would take care of the repair, but almost three months later the critter guard is still sitting on the sidewalk. This seems like a relatively minor issue, and I've tried to be flexible about the solution. I would be satisfied either with Oak reattaching it as promised or with enough information to understand what is needed to fix it properly. I chose Oak in part because of its participation in Ann Arbor's organized solar group-buy program, and I otherwise like the solar installation. I'm posting this review because the normal service channels have not resolved what should be a straightforward service request. I hope someone at Oak sees this and gets it taken care of. I'll be happy to update the review when it is resolved.

STAY AWAY! I…read morecontacted Absotemp because my air conditioner broke -- right before a heat wave. I was told that there was a service charge of $90 and was given a 4 hour window. Matt, apparently the owner of the company, came a few minutes after the end of that window, a couple minutes after 4:00 p.m. (BTW, he smelled of pot.) When he got here, he asked what the problem was & I explained that the air conditioner wasn't working. He immediatey went to the furnace. I told him I wasn't having trouble with the furnace, it was the air conditioner. He then proceeded to tell me that they are connected, my furnace is old and inefficient, and possibly dangerous. He spent a lot of time looking at it and taking pictures. He then got a phone call and was gone for about 15 minutes. He came back and continued explaining to me about the different kinds of furnaces. I reminded him that I called him about the air conditioner. He asked what kind of thermostat I had and then he finally went to look at the air conditioner. He said that was old as well (both were probably original and from the 1970s), but he couldn't figure out when. He called someone about tracing the model, but they couldn't do it either. He then came back into the house & said he'd go into his truck and write up an estimate. An hour and a half later, I went outside to see if he was still here. All of his prices were really high. And again, it was AIR CONDITIONING repair that I contacted him about. After he asked if I had any questions, I said, "I asked you to come out because of the air conditioning. Can you do anything about it?" He huffed and went outside. He came back in after a couple minutes and said that it was the motor fan and "There's nothing I can do about, it Sweetie." :O (That was the second time he called me that!) When I asked if he had any suggestions, he said "Stay in the basement." It was not said with humor. He then asked for a check ("or an ACH") -- AND HE DIDN'T DO ANYTHING except waste nearly 4 hours of my time. I had 3 other companies come out after that. Not a single one charged for an estimate, they didn't take ridiculous amounts of time, and they didn't try to oversell me. Needless to say, I chose a different company.

Then, the previous owner had some valves replaced, and when their service person pushed on some pvc pipes that weren't properly secured, he broke the system, which eroded my whole side yard, and sent water up against our foundation. I called to ask about them coming out to fix the problem. They scheduled an appointment to come out on Tuesday. The scheduler was not very friendly either. After waiting for an hour after the appointment, they called and said they weren't going to service our address. So they are refusing to honor their warranty, and they refuse to tell us why they won't take care of their work! What a joke this place is!!

Further disappointing was that nothing was cleaned up and the old water tank was left trapped between the new water tank in the furnace for me to deal with. We had to lift the old partially filled, very heavy, tank up and over the old water tank.
