Sold us a hvac system , less than couple years later the compressor already is failing. Don't seem to care to contact you back once they got your money for new system. Also when they installed it they tried taking short cuts with install. Like asking if i want a new ac line run or use old one and big 4"" filter compartment well yes i paid for it. Can't believe this noisy compressor it is rediculous. Now itll cost another $1500. Sold me a pos system if you ask me.

Don't use Classic Aire Care/Faszold! I called them to do ac service a couple weeks ago. Tech says outside unit isn't to dirty but I'm missing 3lbs of freon. It will cost $500 to replace and $100 per hour to look for the leak. Tech was Brian. I had had ac on couple times already and no issue. I got Johnson Heating & Cooling over and they said no problem, no missing freon. Johnson had installed system 14 years ago. I called Faszold because of $90 dollar service. At least Brian didn't let freon out of my system! Don't use Classic Aire Care/Faszold!

Won't call back. Doesn't notify you of recalls or known issues with equipment they sell and install. When you do have a problem they won't return your call. Their ""techs"" are all just out of school. The people who answer the phone have no concept of how a heat pump works.

Ac went out in the middle of the night. Called faszold at 9am that morning. Got an appointment for 2 days later. By 3:15 they called me to say they had a tech open if I had time. By 4:30 my ac was back up and running and my tech was really nice and professional. I'll be doing all my services thru them . Thanks matt

Called this morning and they were able to fit me in today for a service call. Their technician diagnosed the problem as being a bad circuit breaker and not a furnace issue at all. I appreciated the honesty! He had to leave to get a new circuit breaker and came right back to replace it.

I'm happy with the service - prompt and courteous - but I am not thrilled with the high cost. The service call was $89 and a new circuit breaker should cost only $20-$30. I was charged $331.50 total, which I've been told by neighbors is very, very high for such a simple fix...Oh well. At least my furnace turns on now.

This is sort of a double-header, and includes a review for today and from a service call about 2 years ago. This company and their techs are great. Two years ago, a day before we were supposed to head out on vacation, we found our water heater leaking. We called them, they came out quickly, got the permits they needed, and we went on vacation without having to worry about it.

This morning, our furnace wasn't kicking in. No vacation plans this year, but the technicians came out quickly, found it was an in-warranty part, and got it replaced quickly. They were smart, knew what they were doing, and professional (and wore masks). We'd absolutely call Faszold first for any HVAC issues down the road. Thanks!

We were looking to replace our entire HVAC and humidifier system, nothing was wrong with our current system but it was getting to the end of it's lifespan. So, we were in no big hurry. We had 3 companies come in and give us suggestions and estimates. All 3 companies recommended basically the same system for our square footage which made the decision come down to warranties, timing and how the representative talked with us. We did our homework (I recommend all potential customers do their homework) prior to all meetings and had a list of questions we asked all 3 companies to see if we would get the same answers. After weighing all 3 quotes, Michael from Faszold presented the best price for the best system with warranties that provided better coverage. Michael actually was the only company that did a heat balance analysis our our home and recommended a system that would be the most beneficial and not higher (and more expensive) than our home needed, even taking into account that we will be finishing our basement including a bedroom and bathroom suite, family room and bar area. Michael was able to work with us on timing so the system was installed on a day when the weather was good and fit our schedule. The team that was onsite to do the install was professional and efficient, removing the old and installing the new in about 7 hours. We would highly recommend Faszold, fortunately we will not need them anytime soon.

Had used Faszold years ago but haven't had them out recently. Was always happy. Got out here quick after calling this morning. Nice technician but price for a simple furnace ignitor replacement was high! Diagnosed quicker, fixed quick, but seemed much more expensive than expected.

Edit- credit the team at Faszold for reviewing pricing and noticing an error. They called and it's been taken care of. Back in the top of my call list for sure!

I was very disappointed with Faszold. I told them our condenser fan motor on our Lennox A/C unit was locked up and to have the service tech bring one with him when he came. Shaun showed up on time and I told him what was wrong. He checked the capacitator and confirmed it was ok. He then said the motor is locked up. He said Lennox has specific motors and he would have to get one at a whsl parts warehouse in O'Fallon, Mo. He then proceeded to tell me it would be $540. I told him that was at least $300 too high. Without knowing for sure I said a motor can't be more than $120. I googled the P/N and can buy the Lennox motor on Ebay for $113 with free shipping. Unfortunately it would take 3 days to get it. I then called Scott Lee HVAC in South County and they are selling me the fan motor for $164 and I can pick it up before 5pm today. I can install it in less than an hour! I just saved $376 but unfortunately paid Fazold $65 for a service call.
