Sunday evening mid-July when I got home, the temperature in my home was 81 degrees. I called McCullough heating & AC first thing Monday morning. They were able to come out within the hour. The young man who helped me, Henry, was very knowledgeable & ...professional. He checked everything & shared options of what I needed. There was no pressure, just honest information. I will call them again when I need AC work.Read More...

He showed up late he tried to sell me 12 lbs of Freon that goes in a 3 ton system he also tried to tell me that I needed a whole new system when in fact I got a secondary opinion from another company they found the leak and didn’t charge me to find it ...informed me that it was in fact the coil that was bad and the leak was happening at the connection point plus when I went to the attic just after nick left my whole ac panel on the inside unit was left sitting in the insulation!!Just because people live in a nice house and have nice cars doesn’t give a company like McCullough the right to upcharge and upsale someone on something!! I am extremely disappointed with this company. What ever happened to the days when a technician was a technician and not a salesman this company doesn’t care about the customer it only cares about its bottom line !! FYI your ac system consists of Inside a big metal box with a computer on it a coil some dampers and your air filter your outside unit is just a large radiator fan and 2 metal pipes that run to the inside unit . Now tell me why I would need a new system if everything else works fine minus it not blowing cold air why not just sell me the coil ?? EDIT: the company called and tried to resurrect the issue that was Big of them for that that’s why I updated my review to 2 stars . Thanks for reaching out !!Read More...

McCullough team is very professional and handles the concerns with due diligence. They came for second opinion for air handler change and i decided to go with them looking at there professional team and reviews. They gurantee satisfaction with there ...work and resolve any issues that comes post installation. We had freezing pipe issue post installation and they quickly sent there experienced representative Kyle on 4th july to resolve issue there after . I can trust them with any HVAC issue in the future and will be at peace that it will be taken care by professional team.Not to forget there Manager Shelton personally messaged me and assured me that work will be completed to the satisfaction . Thanks McCullough team for the great Job. Thanks PrianshuRead More...
