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!

Then, when it comes down to appointment day, and they have all of your information, it seems the price has gone up to over a hundred dollars and now they can sell your information however, they wish. I really wasn't sure if this place works like that so I decided to call. After calling eight times in a span of ten minutes it's clear the phone number listed on here. Doesn't work.

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 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!
