We just had our annual air conditioning check up. The work was performed by Service Technician, Bracy Scott. He was exemplary in his efficiency, effectiveness, courtesy, and general professionalism. Bracy continued the tradition we have come to expect from this splendid HVAC company. The sound choice we made all those years ago was once again confirmed through the good efforts of Bracy Scott. It was a pleasure doing business with him.

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!

(I should start by mentioning we don't know which location this was from, but as one branch shakes,…read morethe whole tree moves.) We made an appointment for our boiler furnace check up and reset thermostat. We were given an appointment window between 8:00-12:00. It's now after 4:00 and still no one showed! We called them around noon and were told we indeed have an appointment. The worse part for us is that my husband scheduled off for today so we could do something together. Instead we wasted an entire Friday waiting. No calls to apologize or explain. What kind of company does that?! So, at 4:30, the McVay guy showed up. 4 and a half hours past the window time given us! He looked at thermostat, saw it go blank, and informed us we needed a new one at $285! We declined. Turns out, our thermostat needed new batteries. So, not only do they not honor appointment times, they try to sell highly marked up products to people that don't need them. Too bad they can't be honest and punctual, they would get life time customers. We will certainly never use them again.

Homer was always there for him and now his Sons are there for me too. When my furnace cut out in the middle of a cold snap, I didn't panic, I called Homer Nine and Sons. Their team was on-site the same day, a complete diagnostic and furnace repair done the next day. When my AC cut out at the first sign of above 90 degrees, Homer Nine and Sons was there to quickly diagnose the issue and replace the capacitor the same day! As a maintenance member I saved on call out fees and parts. Now, I proudly adjust my thermostat without worry thanks to Homer Nine and Sons. Don't worry about your family's comfort and safety, call Homer Nine and Sons.

They could have just come out, done the one-minute fix, and charged us for a visit, but instead, they saved us time and money with no profit for them. How many companies would do that for a customer?
