Our furnace quit working on a Fri. We called Jaenke Heating & A/C…read moreand within a short time they had a repairman, Chad come out. He was outstanding, fixed the problem, but told us our 25 year old furnace had problems and would probably need to be replaced. We had heat for a time, then went out. We called Jaenke and talked with Flo, she was truly awesome - got Chad out to our house, he called and ordered a new furnace. Monday morning 2 installers arrived at 8 am, tore out our old furnace, replaced it with a new furnace. The 2 installers were excellent, explained everything to us, and by noon, we had heat. Was amazing, broke on Friday, and by Monday noon, a new furnace and working perfectly. We were so, so happy with Jaenke and their workers and Flo. Gary L. Schnur, Waterloo, Illinois

Crystal Heating and Cooling installed my furnace when my house was built and they NEVER registered…read moreit. Without me knowing that, they put me under their VIP (joke) maintenance agreement which was almost $300 a year and when I really needed it, they ghosted me. I called when my furnace would not kick on during a cold spell in the fall and wanted my maintenance done for the upcoming winter. The office girl read the notes from the past spring stating that the service guy had to "spin the inducer" to get the furnace to kick on. They never got a hold of me for replacement or let me know what was going on. Come fall, of course the furnace would not work and I had to call three times to try and get something done about it. They kept telling me they ordered an inducer and it would be on the next day's truck. I even had the office girl giggling out loud while I was trying to talk to her. So very rude. I never hear back. I finally called another company and found out not only was the inducer broke, but there was a hole in the head exchanger, which could have been endangering my life this entire winter season due to a gas leak. I would not recommend Crystal Heating and Cooling to anyone.

Fantastic company through and through. The estimator, Brad, was extremely polite, knowledgeable,…read moreand thorough. They were up front about pricing and product availability. Once all was settled and signed, I had a new air conditioner installed 6 days later (could have been sooner if not for a holiday weekend). Installers were professional and did fantastic work from one tradesman to another. All for $2000 less than Hoffman Brothers quoted me. I'll be recommending Crystal to anyone who asks.

I always think it's the cheapest resolution. It was kinda late on Friday, and I wasn't going to live through a weekend of hot in the house. When I called, she took my info and the situation, put me on hold for a very short time, and then came back saying someone would be there in 30-45 minutes. HOLY COW!! And that's when Bob arrived. The motor was out. Groaning and groaning. It's outside. I can't hear that. And I don't go check that. Bob gave me a new motor and on top of that did my fall inspection for the furnace, and I'm good to go when it gets cold. Changed out the filter and performed other appropriate seasonal checks. Spectacular service. Amazing people. Bob is good. He knows his stuff. He's been in the business for a long time.

I had to pick a new HVAC company for servicing as my old company (Harster's) had been subsumed by a…read morelarger company. So far my experience has been up and down. This spring, the first technician took way longer than my previous experiences had been but my AC was serviced. I actually didn't turn it on until June but the downstairs unit was not cooling. The upstairs unit was great. Another tech, much older dude, came by and when we went out to the two units, he saw that the faulty unit wasn't switched ON. Flipping the switch got the first floor unit cooling again. He said he wouldn't charge me. (BECAUSE IT WAS THE FIRST TECHNICIAN'S MISTAKE!) I guess I now know to ask if the units are TURNED ON before they leave to avoid a headache. Things have been nice and cool all summer but what a boneheaded mistake.

Said he has to charge an hour of labor because that is what the book calls for even though I had just given him 3 other units to service. If it was a one time deal, maybe I get that, but it wasn't.

A $35 thermostat was installed at a cost of $210, in addition to a diagnosis fee of $69.

Full disclosure, I called Degenhardt for a bid, and I was astounded with their honesty, and being…read moreupfront. Bottom line, I have an older unit that needed a repair/replace and they set me on the right path. Degenhardt gave me the facts that I needed, and I will call them again. I recently repaired a furnace, and it needed a subsequent repair. Degenhardt recommended the repair, and recommended I use the previous service provider to maximize warranty. He also noted considerations when I decide to replace, which all made sense. I can turn a wrench, and I have serviced my HVAC in the past, but Degenhardt is next level. Dan clearly is well-informed on the practice and science of HVAC as evidenced by his assessment, recommendation, and the fact that I am in a nice cool house again. TL;DR: Hot AF STL in Aug. Paid another contractor to fix the AC fan, broke again. Degenhardt recommended a fix, I trust them, way less sweaty. Call them again no hesitation.

Hands down best service experience I have ever had!…read more My tech was Joe and he not only was extremely kind and respectful with a positive attitude. Being new to the midwest, I was not very familiar with heat pump systems. There was water leaking from the unit and I filed a claim with my home warranty service who matched me with New Systems AC and Heating to complete my claim. Being new to a city, in my experience at least, home repair service companies tend to be hit or miss especially when you are under a warranty who only have select companies who they choose to contract with. I can't express enough how please I am that we were paired with New Systems AC + Heating. Our tech, Joe really went the extra mile to explain to me how my system worked and answered every single one of my questions that I bombarded him with. He was thorough, worked hard and gave helpful advice/tips on ways to best run the system to maintain its high performance and extend its longevity. In fact, I was so impressed with the service, I called the company after the tech left to let them know how outstanding i thought there tech was and I am not one to usually do that. Their receptionists are also very chipper and upbeat and very accommodating to any needs or requests I have made. All in all, a very impressive company that was knowledgable, provide good work, go above and beyond for their customers and are fair and honest. They earned a loyal lifetime customer and I will make it a point to recommend this company in the future to friends, colleagues and neighbors.
