What Our Customers Are Saying

I had my furnace & water heater replaced today. Brian & Kenny were great! It’s a tight closet that the units are in & while I could tell that it wasnt exactly easy they both worked together to accomplish getting the job completed in a timely & professional manner. We’ve had Vernon since 2001 & we’ve always received excellent service whether we’re calling the office or speaking to a technician. I recommend Vernon to everyone that asks. Thank you for providing excellent customer service. I hope with the virus that’s going around that the Vernon employees stay healthy & be safe. We’ve always been pleased with your services.
