My AC stopped working Sunday evening, after all HVAC businesses were closed, so by the next morning…read moreI was hot and miserable. After doing some research online looking for local recommendations, I called Ziegler Heating & Cooling on Monday morning at 7am. I was sent to voicemail when I contacted Ziegler, so I hung up and called Knoechel. (I called Ziegler first because I have an American Standard AC unit, and based on Zieglers website, it appeared that American Standard was a preferred brand of theirs/they may specialize in. Whereas Lennox appears to be the preferred brand at Knoechel. - my thought process was, if I was going to need a replacement, then I'd want an American Standard, hence Ziegler was my first call). Spoke with a woman who answers incoming calls for Knoechel, who took all of my information (contact info and description of the problem) and informed me that I'd receive a call back shortly. 30 minutes later I received a call from one of their techs who then arrived at my house less than 10 minutes later (I am local in Zelienople, where they are headquartered). Within an hour my AC was running normally again without any attempts to upsell/oversell. (Thorough cleaning of AC coils on the outside unit, replacement of dual capacitor, and temperature checks - about an hours worth of work, $177) All that work PLUS the expediency in response time came at a price that was in line with a competitor a family member had used last week located in Pittsburgh (which was too far away to service my house in Zelie). Without question, I'd recommend Knoechel!

Give 'em a call!

I rely on my fellow Yelpers to give me honest, unbiased reviews of local businesses. Most of my…read morereviews and searches are about food, but occasionally I have a need for another type of business and this is the first place I turn. You all led me to this small, local business and you were spot-on, so I am paying it forward by adding my review! My family had our pipes freeze in the winter storm this Christmas. Friday, it was the cold water pipe, which took seven hours of work to unfreeze. We thought we were in the clear and counted our blessings as we kept the cold water running overnight Friday -- only to discover Saturday around noon that the hot water pipe was now frozen solid. Twelve straight hours of effort with hair dryers, space heaters, boiling water pots, heating pad wraps and everything else we could think of did not work and we went to sleep Christmas Eve defeated, wondering how we were hosting the rest of my family on Christmas with no hot water, dishwasher, etc. (Our efforts did eventually pay off with the hot water coming on at 8 a.m. Christmas morning and no pipes bursting. So grateful.) During this nightmare I called a number of plumbers who list themselves as emergency 24/7 plumbers, but only Gary from Brickhaas called back. He called during the span of time that I thought everything was under control, but I asked if we could be booked for later in the week to unclog a bathroom drain I've had a problem with lately. Glad I booked them as, after the pipes thawed, the under sink drain was leaking slightly so Dominic was able to take a look at both of these things today. He called with a 20-minute heads up on his arrival, efficiently took care of the clogged sink and an aerator that was limiting water flow, installed a new kitchen sink trap assembly (which he said I could honestly take or leave; I appreciated the honesty but opted to replace for my own peace of mind), and offered solid advice about what we might do if plans to better insulate those water pipes in the future didn't work out re: rerouting the pipes from their current, poor location. He was highly knowledgeable, didn't hard sell anything and I absolutely got his card as I'll be calling them for future plumbing needs. Yelp comes through, as usual!

The best part about these guys, their initial service fee is not outrageous, like I see with most others appliance services. The service tech they sent, Jerry, although a young man in his early 20s, he was extremely knowledgeable and helpful. Luckily, my furnace only needed an adjustment to the gas pressure to place it back in normal operating mode. So my initial fee covered his visit and the adjustment, unlike other vendors I've used in the past where they look for things that they can charge you more or say they're about to break, just to charge you more money for the service. I'm pleased to say, this is NOT the case with this company..... I highly recommend this company!!!!

My husband and I felt we needed to have our AC unit checked as it had been running constantly and…read morewas 24 years old .. it was also located under our deck ( installed far before we ever moved in.) My husband contacted Nemcheck for a service call and they were able to come out in a very timely manner. Due to our AC unit being located under the deck, and the fact that it was 24 years old, it was running constantly, and it was determined that there was an issue. It was more cost-effective to purchase a new AC unit. The technician was very thorough in explaining what our options were. Rob came to determine where we would like our new AC unit , to confirm the AC unit we wanted , and to take measurements also . Again, he was very thorough in going through the options and what was going to happen with the install. After ordering the unit, the Nemcheck team arrived for our scheduled install. The whole team was very friendly, respectful and working hard all day. My husband and I are thrilled with our AC unit and would absolutely utilize Nemcheck Heating and Cooling in the future. Stellar, highly recommend!

I have two hot water tanks, one I paid 1900 and it ran for 9 years. The one just went bad and this 8000.00 one never worked. I turned it up to 130 and I have no hot water or pressure. I called them to ask if there is a warranty on the tank and told me "well it's two years old." He wanted 179 to look at it. After reviewing the bad reviews, I told him I will add one too. He hung up on me... I do not recommend this business. When he was at the house, he started telling me my Generac was not done correct and wanted other work it seemed. I am quite happy with my Generac company. I had a radon business scheduled and he wanted this service also. I am quite happy with my radon company. No thanks Kennihan. I don't even think one star is appropriate for this business.
