They've helped us on several of our properties and are always quick, fair, and dependable. One Friday evening, I was having trouble with a condenser, and they took the time to walk me through the problem over the phone -- saving us from a major issue over the weekend. It's rare to find a company that's so willing to help and genuinely cares. Couldn't recommend them more!

The gentleman came to the house and looked at her furnace and told me that he could not order the…read moreparts for both blowers. I was able to have a gentleman come in that works in HVAC. He was able to order both motors from the supply house fix the furnace. I was told the furnace has parts that can be ordered and that the parts were not obsolete. I would not recommend OshKosh heating and cooling to anyone. I feel I was lied to to try to sell a new furnace when the gentleman came in to look over our furnace, he said that 21 year old Furnace. Furnace was at the end of its life expectancy. However, when the other gentleman came and looked at the furnace, he told us the furnace is built to last 30 to 40 years and parts are obtainable. All Lenox furnaces have parts that are obtainable from a wholesale house I was completely put out by this conduct I would not recommend Oshkosh heating cooling to anyone.

We hired Kollmann Electric to move a generator. To start, they dug two pipes out of the ground and…read moredidnt backfill the trench. They also did not patch any of the holes in our foundation from where they pulled pipes out of the side of the house. We were left with large holes in the foundation of our house that they did not caulk shut. They also did not use hole closures in the generator. Most importantly, our transfer switch was working perfectly until Kollmann came and rewired it and fried our coil. Now they refuse to pay for something that they broke. They billed us and are now expecting us to pay for an incomplete job and left us with an nonworking unit. Their employees were also playing pool on our pool table while they should've been working. The owner Jeremy, is refusing to take responsibility for any of the mistakes made by his company or damage to our property.

Terrible and a waste of time. Wiggled some wires then charged us for talking to make up for labor.read more

June 13th- blower on furnace pukes. Called Ryf. June 14th…read more- technician called me from his phone. Said he'd be going over to look at issue. About 1/2 hour later, received phone call from technician's informing that it was the blower and it would need to be ordered. He said he'd let me know if he can get part. June 15th- No word back. Texted cell number of technician if he was able to order the blower. Technician responded back that yes, it would be in tomorrow. June 16th 7:17am - Texted technician to let me know when blower can be installed. Received no response, until 4:28 pm when I missed phone call. Called Ryf back and went to answering service. The answering service told to call Ryf back at 7:30 am on Friday as this was emergency phone service. I saw a voice-mail on my phone and listened. All it said was to call Ryf to schedule time tomorrow. Texted technician to let him know I received message and tomorrow is good. Received a message back saying he didn't send message and call shop in the morning. Received a second text from technician stating that this was his personal cell phone and to stop sending him texts. June 17th 7:30 am - 7:45 am - Called Ryf 7 times and kept going to answering service who had no way of contacting technician or employees. Found a number on my phone that came after the call from Ryf. Spoke with second technician who berated me for sending early morning texts to first technician. I told this second technician the first technician initiated the conversation by calling me on his personal phone. Second technician says in an unfriendly, threatening tone, 'Do you want your blower installed?' I said yes, to which he says I have to be patient and it will be installed today or early next week. I told the second technician that I have been patient and haven't heard anything back to get this scheduled; and that I called immediately after last night's phone call from Ryf and it went to the answering service who said to call back tomorrow at 7:30. The technician said he'd meet me at the house. The technician that did show up was rude, walked right by me stating his name, then asked how is this being paid for? Not so much as a sorry, good morning, nothing. As I write this, it is understandable how these companies completely believe that the customer is never right as they rake you over the coals. I do not recommend this company for HVAC services to anyone. Rude, inept, irresponsible employees. The company is unprofessional and will not keep in touch with you. And some advice for the company: if your employees don't like receiving text messages from customers, don't have the employee contact the customer from their personal phones. If your company says you open at 7:30am, then have an employee there at 7:30 am to answer the phone, not the answering service. Give classes to your employees on customer service. It goes a long way.
