I would rate Karner Mechanical a 10++ but it wouldn't allow me! Why? My oil furnace stopped working 3:30am Friday Morning. Since I don't have a contract with my oil provider (they don't provide that service) they recommended someone who they typically use. This company came out Friday before a holiday weekend and when they left around dinner time, they said it was fixed, however our heat never came back on after we got back up to temp around 8pm. When we called to have them come back at 1am Saturday Morning, they sent someone over 12 hours later and they could not fix the issue. They said they would be back again the next day with a rebuilt motor. Came back the next day, and said he couldn't fix it and will be back again the next day - New Years Day. (Mind you I have had pretty much no heat for 2 full days and outside temps are negatives. I live in an old house with minimal insulation, if any and my inside temp is now at 36 degrees). So as he left, I kindly told the person we would find someone else (at 6pm on New Years Eve it was next to near impossible but we were desperate and couldn't wait another day) and we wouldn't need him to come back tomorrow. I began calling anyone but they all turned us down - one even taunting me by telling me he lived right across the street, had all the supplies and motors etc on his truck, but since I didn't buy oil from them, he wouldn't come over. Next on the list was Karner Mechanical - I said a prayer and hoped for the best. To my surprise, a gentleman picked up and I began explaining our situation. I said I would send him photos quick to see if he would even be willing to stop because at this point we were more than desperate! He called me back after receiving the photos and was at my home within 15-20 minutes. Not only did he answer the call, he was highly professional and responded to our problem immediately during the busiest cold blasts of this year. Joe checked out the cob job done by the other company, made sure my heating system was safe to use and got the furnace up and running - all within an hour or so. He potentially saved us thousands of dollars worth the damage to the pipes and radiators by responding immediately on New Years Eve! Highly professional - extremely knowledgeable - honest and thoroughly explained things. I will not use anyone else going forward. Karner Mechanical will be my go to service company from now on - period! read more
