Our…read morefurnace is 30 years old and he said that it needed a new ignitor switch that had to be ordered and it would be a couple of days. after calling the company they said they could get it here next day! Zack explained that this might work or it might not and I explained that we will be selling this house in the spring so I really didn't want to invest in a new furnace unless I had to. Next day Jordan arrived with the part and he installed it and with my fingers crossed we turned it on and it worked!!! YEA!! Both of these guys were great to work with and I highly recommend Corcoran & Harnist! They were very professional and knew what they were doing!

He explained things thoroughly. And I now have surge protectors to prevent this from happening again. He even offered to bring me a window ac but it wasn't necessary because he was here early the next morning and had it up and running and let me know about how long it would take. I'm so glad I called them. They gave me a good price and I know I can depend on them to keep my ac unit working efficiently for a long time.

I was very stressed because my husband was dealing with it standing in water with electrical components around him. I called Kellerman Heating and was told someone would call. Turns out my phone was not working properly and I missed that call and my husband said that I was rude when I left a message on the after hours recording. I do apologize for that. Anyway the owner came to the house because he could not get a hold of me and took care of the issue. I would say that he went above and beyond in doing so and I do appreciate that he did that. He took care of the issue which also turns out was not from anything that they did but the drain was clogged from other debris like when they built the house ect. Thank you to Kellerman Heating & Cooling. If you need work or a new Central Air Unit call these guys. I would give them a 10 out of 10.

A few days later a house roofer worker came in my back door and said I smell gas do you have windex he found a big leak in the shutoff valve right next to furnace and when fixing it, all the gas piping inside the furnace came apart. The house worker said that would have blown your home and the neighbors home sky hi you would have been a dead man. luckily gas was off. My name is Jon. I would never have these people come anywhere near your house. And i had to get a quadruple bypass maybe from breathing natural gas for six years. I should sue them.

I used Jonathan Soard's service for my furnace. I really wish I had used a more reputable company…read more Jonathan is still learning and obtaining certifications for HVAC but his customer service is absolutely horrible. He tends to act on his emotions when dealing with people. He is loud and lacks understanding of his surroundings. Upon completion of his work, Jonathan sent me an invoice for an insanely large amount. $900 for cleaning the motor and changing the capacitor of furnace. I was shocked. He threatened to call a lawyer and put lien on my house when I asked him to lower his price. He yelled outside of my house putting my reputation on the line infront of my neighbors. I had to call the police to calm him down. I hate to write reviews like this but the situation he put me through was very traumatic. I would highly suggest using a reputable company for service. Best of luck.
