**⭐️⭐️⭐️⭐️⭐️ Outstanding Service and Professionalism**

From my very first contact with Faszold, I was met with a warm and friendly response. Every team member—from the receptionist to sales and service—followed through on their promises with professionalism and care.

When my AC failed, I was in a tough spot. My family was stuck in a hot, humid house with a serious risk of mold. I needed a fast solution, and Faszold delivered. They provided a high-quality AC unit quickly, installed it professionally, and treated us with genuine kindness throughout the process.

I have nothing but positive things to say about this company. Their reliability and customer-first approach truly stood out. When it’s time to replace my water heater, I’ll be calling Faszold again without hesitation.

Please pass my congratulations to the team—especially to Mike and Corey, who performed the installation. Their work was exceptional and deeply appreciated.

La’Quan was awesome. Our drains have been working perfectly since his visit. The booking process is what I was unhappy about. I tried booking online with Faszold, but the page went blank when I submitted the request . . and I never received any kind of confirmation . . . so as far as I knew, the booking never went through. Much to my surprise La’Quan from Custom Aire Care shows up on my doorstep the next morning. Feels a bit misleading. When I could potentially pay a company hundreds or even thousands of dollars, I want to be sure they are a company that I can trust. And I’m still waiting on the quote to solve my ventilation problem. So five stars for La'Quan and three for the company.

Both Kent & Thomas were professional, informative and courteous while installing our new a/c. They were quick and provided much-appreciated cooling during the heat spell.

Very helpful and friendly. Love that there is a 24 hour hotline for emergencies. They came to my home at 10:30pm to check out my AC.

Justin wore covers over shoes, completed work efficiently, showed me details of the air conditioner service, courteous, and taught me a new trick on the thermostat.

Our a/c heating installation was flawless. Professional and courteous to the max. Every question was answered in a manner that was informative. The cleanup was beyond expecting, and the install time was much shorter than anticipated.

I’m thrilled with the exceptional service provided by Michael who installed my new heat pump and furnace! Their expertise was evident from start to finish—they explained the process clearly, worked efficiently, and left everything spotless. Not only were they highly knowledgeable, but their friendly demeanor made the entire experience stress-free. The system runs perfectly, and I couldn’t be happier with the results. I wholeheartedly recommend Michael and Faszold Heating and Cooling to anyone needing reliable, professional HVAC work!

BEWARE THEY WILL SELL YOU ON THINGS THAT DONT NEED TO BE REPLACED AND CHARGE YOU AN INSANE AMOUNT.

DO NOT CONTACT THEM

By far the worst experience I have had with any service provider. I had them come take a look at a brand new water heater that was not delivering hot water.
1. They gave a 4-hour window from and still showed up 45 mins late
2. I told them to charge me for the visit and not my tenant, but the technician gave my tenant no option other than for her to pay it
3. THEY DID NO DIAGNOSTICS AT ALL the technician simply took some photos of the water heater charged $109 to do so and then they sent me a quote for over $2,000 to replace the water heater with a $500 water heater

The water heater was new and all that was needed was a new Heating Element which is less than $50!!

Got a second quote from Mike Faszold on a new HVAC system. Thank goodness we did. $6K less than the first quote and Mike has the knowledge and experience we were looking for to guide us in making the right choices on equipment. The installation was quick and flawless, we just passed city inspection. Thanks!

Thank you Joe.

Excellent company all around. Great service, prices, and quality products amd workmanship. Got a new hvac system and Clay and crew went above and beyond. Cleaned up the area and provided supplies that made it look and function better than it was before. Mike was able to find rebates and give a great price. System works great. Everyone made sure to explain things, answer questions, and go the extra mile to be sure I was satisfied, comfortable, and happy.

Dan F came out for an estimate. The man really knows his stuff. He pointed out things others had missed and also praised another company's quality work and didn't talk them down. His estimate was almost dollar for dollar as other reputable companies. Finally he showed me my options with zero pressure to commit.

Service done professionally and promptly. Work area cleaned up and trash and old equipment taken away. Michael P. and team were courteous and did a great job.

Michael was on time for our appointment and was friendly and professional. First asked if he could talk with me and then ask questions concerning how comfortable my present system was. Asking about humidity and hot and cold spots, etc. Then he proceeded to discuss a couple of his products and the differences. Answered all questions that I had. He then went down and took pictures and measurements and went outside and did the same.
He was able to give me a quotes for a couple different options and explain how long installation would be and how soon they would be able to install.
He also gave me his number where I could call and question any differences I saw in other bids or any questions I had about his bid. He was able to clear up a question I had once getting another bid.
I appreciated the fact that he explained the differences in systems, explain the differences in rebates, etc.
I would highly recommend Michael to anyone looking for a new HVAC system

We've been using Fazzold Heating and Cooling for the past 15 years. When it came time to replace our old, outdated system, there was no other option. They were fast and everything works perfectly. We highly recommend Fazzold (Classic Air Care) for service and new system installs.

The gentleman, Greg, came in and found the problem within minutes. Had the part (starter) on his truck. He replaced it and cleaned my furnace for me. Greg was so kind, professional and honest. Those are traits that rarely exist anymore. Thank you so much, Greg ! Job well done !

I called Faszold this morning because I was concerned that my humidifier was not working and I needed a visit for routine maintenance on my new furnace. Faszold was able to schedule a technician for today. He was very personable and knowledgeable and explained everything that he did to the unit. He also provided pictures and had some suggestions for how to run my humidifier. I am more than satisfied with the service I received. Faszold was prompt in addressing my concerns and Justin was very professional. I would recommend Faszold Heating and Cooling for your furnace and air conditioning needs.

Our A/C was having problems staying on. I called Faszold and they sent someone out the same day. Service Tech Anthony determined the problem and our A/C was up and running within an hour. Anthony was friendly, courteous, and knowledgeable and took the time to help educate us on what the issue at hand was. Happy customer here!

I came home to my furnace not working, after talking through my issue with the overnight technician he reassured me I would get a phone call the next morning when normal business hours resumed. I actually received a call 10 minutes before they opened for the day! I was very fortunate that a technician was available right away and my furnace was fixed before 9:30 am. The technician was very honest and upfront with my issue and fixed my furnace in very little time. I have always been impressed with their professional and expertise.

Our AC wasn’t working properly today and Faszold was able to send out a technician the same day, which we thoroughly appreciated! Justin was friendly and professional. He discovered the problem right away, took care of the issue, and had the unit back up and running in no time. Thank you, Justin!

The technician called to update me on his arrival time. He covered his shoes to prevent tracking anything on my carpet. He performed a very thorough maintenance check on my furnace and A/C. My A/C was not working when he arrived, but he quickly found the failed component and got me going again. As always, very happy with the professionalism and fair value I receive from Faszold. Now that they are part of Classic Aire Care, I have to change my review. I called them in October to schedule my fall tune up under my maintenance contract. They gave me a December 29th date. Unfortunately I encouraged my daughter to purchase a maintenance contract from them. She did so and ended up paying $900 for A/C service with another firm because Faszold said they were booked and could not get to her for a few days. SO MUCH FOR SERVICE PRIORITY. There committment to taking care of their loyal customers has ended.

Excellent service! Jason was professional, arrived on time and fixed the problem. The office was very helpful working me into the schedule because my furnace had stopped working. I highly recommend Faszold.
