It definitely deserved retirement. We were quoted a good better best scenario, and after considering we went with best. Because of the heat wave, they could not put it in immediately, but got us on the books as fast as possible and even texted a few times to make sure we were still up and running until they could install. Customer service is top notch!!!

In the past I was fortunate to have a neighbor for minor plumbing work. Last week our washer died…read more A new one arrived but they couldn't install it because the connector hose was corroded and they weren't able to remove it safely and didn't want the responsibility if something broke. We have a big family so that caused a lot of stress. These folks were nearby and had 4.8 stars here so I called them. They couldn't have been nicer. I was put on hold for a few minutes as they tried to find someone to come, and they said it would be as long as three hours, which was still great. They were here within 45 minutes. Their technician was polite and talked us through what was going on. He had it fixed within 30 minutes and even did some minor additional maintenance to make sure things worked better for us. He aslo suggested we buy an extension hose, which we did. Considering we had never used them before, they treated us like a long-standing customer. They will be our go-to going forward! Highly recommended!

Let me tell you about my experience with Klinkey Heating and Sheet Metal…read more My air conditioning was not blowing cold, so I looked up local AC repair companies. Seeing that Klinkey had been in Saint Charles for many years, I decided to give them a try. The individual who came to the door was an older gentleman who looked like a someone's grandfather. He came in and asked me what the problem was. He was polite and soft spoken. I explained the AC was not blowing cold. He asked me where the furnace was so he could check the filter, explaining the problem could be caused by a dirty air filter, and if that's the case it would be inexpensive to repair. I showed him where the furnace was (in the crawl space) and he went in to take a look. A few minutes later he came out with the filter. With a smile on his face he said it looks like that was your problem. I have new filter in my truck and will put it in for you. Will only cost you a quarter, plus a standard service call. I felt relieved. No big, expensive repair needed. Then the service man said as long as he was here, he would like to check the unit in back just to make sure everything is okay. Seemed fine to me. At this point I like and trusted this service man. After showing him where the outside unit was, I went back to work in my home office. About 20 minutes later it dawned on me I hadn't heard from the service man. So I went out back and asked if everything was okay. He had the cover off of the unit and a pressure gauge hooked to it. He shook his head back and forth and said it looked like my compressor was failing. He pointed to a dial on the pressure gauge. I asked him what was needed to fix it, and he said the compressor needed to be replaced. I asked him how much that would cost. He replied that the part should be covered under warranty and shouldn't cost me anything. Again I felt a sense of relief. No big, expensive repair. Then I asked him how much it would cost to put the compressor in. He answered, oh I don't handle that. The office can give you that. I asked if he could give me an a rough idea. Would it be around $100? Or more like $300?. He didn't handle that, but said it shouldn't be too much, it's just a part. I found this to be rather odd. An obviously experienced service technician who has no idea, not even a ball park figure for what it will cost to put in a compressor? Then he did something that caught my attention. He said he was going to disconnect the power until he was back to put in the compressor. I didn't question this, but it did stick out in my mind. I watched as he unplugged the power. The next day I received a call from the Klinkey office. The man said he had the new compressor and he service technician could be out the same day to put it in. I asked him how much it would cost . He said the part was covered under the manufacturer's warranty and there would be no cost for the part. I said, 'How much will it cost to put the new compressor in?' His response: $900. '$900?' I asked. He went on to say how involved it was and that the service technician would be there most of the day. I wondered why the service technician didn't give me some idea of this the day before? Surely he would have known replacing a compressor was an involved job that would take several hours, possibly most of the day, not merely putting in a part. I told the man on the phone I thought it would be wise to get a second opinion. He seemed quite put off by this. But I did get a second opinion. The service technician from the second company plugged the power back in and guess what he told me? There was nothing wrong with my compressor. The compressor worked just fine. The unit was low on freon and needed to be charged. He added freon and the problem was solved. Lesson: ALWAYS get a second opinion before proceeding with an expensive repair.

The emergency call cost over $140, heater wasn't working. Furnace wasn't cleaned, technician said…read moreit was either a bad ground wire or a circuit board. Said he put in a new wire (although had no confidence that was the problem) and was working now but that it was really random. So didn't know if it would be fixed and ordered a circuit board. He seemed very unsure. I've had my furnace serviced before (by another company) so I'm not a newbie. A cleaning wasn't ruled out but more expensive fixes were immediately tried, like he had no clue but would try, I don't know... I called another company because I felt this was obviously poor service, maybe even a scam. Ans as I suspected it needed to be cleaned and a faulty sensor (a minor repair) was put in. And at a very reasonable price. I was left with the impression that I was being taken advantage by Charles McDuffee Co. or that an untrained or poorly trained person came. I will never use McDuffy for anything. EVER. Definitely the worst service repair I've ever experienced as a home owner for over 40 years!
