He left no mess, showed me how to clean my "complicated" filters and went on his way. If you ever have A/C issues... You are foolish not to start with these gentlemen.

A neighbor recommended Welsch to me and I could not be more satisfied . I have a big home with 3 air conditioners and 3 furnaces, so I rely on them to keep working. Colin is our service person, and he is "the bomb". He is always on time, extremely good at what he does, very very thorough, and respectful to not only my husband and I, but treats my house respectfully also. I have one unit in the attic, and he never complains about crawling up that ladder in the heat to check it out. My pricing is a bit more due to the number of units I have, but the quality of service and respect is so worth it. The office staff is very organized also, and always kind /nice when scheduling or troubleshooting a problem.

So this is not my usual review but there is NO WAY I can't brag just a bit on this local business…read morethat is just outstanding! I've used Welsch for over a decade and my family used them before that. So my experience runs deep. First thing you should know: their technicians stay. Meaning you benefit from their experience and commitment to Welsch's service standards, which are high. Recently, I had a blower motor go out. Jeremy came out within the hour (after hours), diagnosed the problem and had Scott on the phone to check inventory. It wasn't easy but Scott was on the phone at 8 AM, ready to set up an appointment to install the motor - less than 12 hours later! Incredible. Look, you might find cheaper but you won't find better service, more knowledgable technicians and an overall feeling of "We got you!" like you do with Welsch.

The water pressure was fine with the old water heater, pressure immediately reduced when they put the new hot water heater in.

In Sept 2026, during extreme heat, a Jerry Kelly technician diagnosed our non‑working A/C as having…read morea seized compressor and said repairs would exceed $6,000. We were then given a handwritten replacement quote on notebook paper with no brands listed and only vague "standard" vs. "high efficiency" categories. The quotes ranged from $19k-$23k, and we were pressured to make a decision immediately. When we said we planned to get other quotes, the lowest price suddenly dropped to $14k -- an immediate ~30% reduction that made it clear the original pricing was heavily inflated. Our home was over 90 degrees inside, and the only option offered was next‑day full system replacement. We called another HVAC company for a second opinion. Their technician found no seized compressor -- just a failed capacitor -- and repaired it within minutes for a couple hundred dollars, restoring cooling within an hour. He also arrived with a portable A/C unit to ensure our comfort if the repair wasn't possible. Jerry Kelly did refund our diagnostic fee and Maintenance Club membership after I contacted them, but consumers should be aware of the high‑pressure sales tactics, questionable diagnostic practices, inflated pricing, and the importance of getting a second opinion before agreeing to major HVAC repairs or replacements.

However, we did not get a call for a couple hours so I would not say they are open 24/7 but they did return our call pretty promptly (within hours). They were very courteous and they returned our call. However, they were not able to get to us until the next day so we did not end up using them this time which is understandable a lot of people were without heat when we had severe low temperatures. I recommend this company their family owned local and customer service is really great.

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.

We have used Classic Aire for almost nine years and have had service calls and twice-yearly checks…read moreover the years. A new HVAC system was installed in our home in late March this year and everything was done professionally and neatly with no messes left for us to clean up. The system worked great until the incredibly damp and cool spring when the AC was having real trouble dealing with the humidity in the house. But Faszold--and its mother ship, Classic Aire Care--kept sending out a couple of stellar technicians to check and adjust the system until they got it right. And this was warranty work--we did not pay for anything as they tweaked settings and made the system work in our home. Anthony and Steve are true problem solvers as they continued to address individual parts like the thermostat and fans and they finally got it all worked out so that the system is able to keep our house below 50% humidity. It was a frustrating time but the company has been responsive and supportive. Mike Faszold was also amazing and continually answered my calls and texts during both pre-sale and after install time. This company stands behind its installs and comes through on its promise of good customer service. Check around but believe what they tell you.

It's too complicated. You need a new system anyway- it's old" said I needed a complete replacement because they can't service my air conditioner anymore - wanted to sell me a $10k unit. Branden came over and did a long look at my unit and agreed that it was an electrical thing- apparently he WAS willing to figure out what was going wrong- got it going again and said when it stops working again to call him so he can figure out where the wiring needed replaced. Spent a long time at my house. Well, it went out a month later and he came over and did everything he could to figure out where the wiring problem was. Took a couple visits and lots of trial fixes. Said he could service my AC just fine in the future and fixed the issue- everything working again. He also has lots of options for when I do need to replace my older system- but it's not now. Very conscientious, very knowledgeable and very patient and tries very hard to fix the problem without taking shortcuts and not wanting to do the work cares more about the customer than making a big sale.

Two weeks later the humidifier fell off the furnace and broke…read more He tried to deny that he hadn't properly refstened it, but after my in-person visit to the company they agreed to install a new humidifier at no cost. For that reason, I had them do a spring checkup, Emma claimed the heat exchanger was cracked, the fly wheel needed cleaning, and the a/c compressor was "over amping." I had a different, highly reputable company check the furnace and a/c, and they found that none of this was true - neither the furnace nor the a/c had any problems. Also, Emma did not provide a written a written description of her service and recommendations, and they have not provided the promised receipt for the payment of the second inspection. They are either incompetent or dishonest, very possibly both.

Tyler came out and found no issue with furnace. 2 days later Bill came out and after 3 hours found that the thermostat wasn't communicating fully with furnace. Still no repairs made. Bill returned a day later and moved thermostat to lower level next to furnace in so it worked thru winter storm and gave me a bid of $400 to move thermostat back to original location in family room. After reviewing the path of the wires through the garage, up into a closet, and finally in through the wall, I decided their were too many possible points of failure and decided to leave thermostat in lower level but needed it moved over a foot so as not to impede doors covering HVAC area. Bill said the cost will be the same per company regs and wouldn't re-bid the job even though it was significantly less time and labor than the previous bid. He also needed to reconnect the A/C so I guess I'll find out this summer if that was done properly. I cancelled on the spot and will hire another HVAC company in the future to move the thermostat 12 inches to the left so I can close the closet door and test the A/C. I'm extremely unhappy.
