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.

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.

DO NOT GO HERE FOR HVAC. WE DO NOT RECOMMEND. Full, honest…read moretransparency: We have a 9 year old unit in our house we have lived in for a couple of years and have never had any cooling issues. We did notice some water near the base of the inside unit, so since we didn't know much about HVAC units we called Jerry Kelly to come take a look. The young man got here on time and stayed for a couple hours taking things apart and getting various readings. By the end of it he sits us down and lets us know our HVAC is near the end of its life and we need to replace the 2 ton unit and it will be $20k to replace and if we want to repair it will be $10k. He let us know his project manager would need to come out the next day to discuss next steps. That night we immediately sought out scheduling a second opinion. The second technician came out the following day. He let us know we just had a clogged hose and a weak capacitor. He serviced the unit where things needed fixed and tuned up our system for the spring. $170 TOTAL. He also let us know we have at least another decade of life in our whole system. The contrast between the Jerry Kelly technician and the other local HVAC company was substantial. One took our 100$ service fee and did not a single thing but try to sell us outrageously overpriced system and add extreme stress. Keep in mind we found our EXACT unit online brand new for $5k so the fact there was a $15k markup was insane. These technicians make commission, which at the end of the day is fine everyone has to work for a living but. Marking something up 15k is ridiculous and I hope others read this and go with the smaller local HVAC companies that care about their customers. I DO NOT RECOMMEND THIS COMPANY.

After several attempts to get this rectified between my wife and Hoff's AR "professional", Pam, I sent Pam a brief email explaining that I was frustrated due to their internal miscommunications and that I would pay the bill but posting about it online. Here is our exchange. Me: Pam, I did not imagine the words that your tech spoke at my house. We will pay the full invoice and follow up with a review on our experience with Hoff. Your technician was professional and fast but communication issues like these are your internal problems that need to be worked out as they are spilling over to your customers. Pam: Oh Troy, I hope you don't think I'm implying you "imagined" those words. There is a chance that the communication can be off, and we continue to strive to be better and improve daily. For future reference there is ALWAYS a service call fee when we are called out to your home. Thank your for your prompt attention to paying the invoice. If your employee makes a mistake then you should stand behind it as a company. First and last time dealing with Hoff.

I had a problem with my air conditioner not cooling. I had used Hoff Heating and A/C for several…read moreyears with no problems. I called them again and Larry came out and said that I needed a new capacitor. The next day the unit still wasn't cooling, so Hoff sent Aiden back out to look at the unit. Aiden said that the unit was out of freon. He said that he didn't know why Larry didn't check it when he came out the first time. Aiden said that the unit may have a leak. He said that he could do a leak check for $175 but he may not be able to find the leak, or he could put Freon in the unit with sealant that is supposed to stop the leak for $185. He said that he didn't personally recommend doing it because it didn't work. He said the third option and the one that he recommended was just putting Freon in the unit and running it and if it ran out soon, then it had a leak. So, I reluctantly agreed with him and told him to go ahead. He came back and said that he had put over 4 pounds of Freon in the unit and it held 8 pounds to fill it up. He ask me if I wanted him to fill it up or stop at 5 pounds. He then told me that his Freon cost $100 a pound. The last time I purchased Freon, I was able to fill the unit for $85. So, I told him to stop at 5 pounds. The total bill for both service calls of $800 and they didn't fix the unit or solve the problem. My son then offered to have one of his friends who does commercial heating and A/C look at the unit. He came over and removed a panel next to the opening and showed me the leak which was very easy to find and see with in 5 minutes. So I replaced the total heating and A/C unit with him and it was up and running with in a couple days. He also gave me his employee discount. He said that the previous two technicians should have taken off the panel and checked for the leak without selling me a new capacitor that I may not have needed and selling me $500 of Freon without insuring there wasn't a leak on the system. So I feel that Hoff Heating and A/C just took advantage of me for $800 and didn't make any effort to really solve the problem. I called the office and left a detailed message of what happened and ask for a Manager to call back to discuss this. It has been a week and they never responded. I don't feel that Hoff did a good job for me and feel that they did not have my best interest in mind when making the service calls. Don't let them take advantage of you.
