"Furnace in my home stopped working. Went through Home Advisor and had one company come over. They had stated that I needed a new furnace.Scott had called and came over within 1 hour, checked my furnace and found that it was plugged. He did the repairs and running great again. This is the second time he had done work for me a year ago on my air conditioning unit.He does great work, honest and his prices are fair. I will not rely on anyone else, except for Scott. He is my permanent repair man."

"Mamayek Heating was very proficient with their installation of whole house central air-conditioning in our 1896 year-old home which never had a unit in place. From start to finish, they accommodated our needs and schedule as well as leaving behind a nicely done project in working order. Thank you to the 3 Bobs for all their help!"

"One Hour Heating & Conditioning was prompt arriving at the scheduled appointment time. My wife and I also appreciated receiving a message that the techs were on their way. Our techs Kyle and Jacob were friendly, professional, and knowledgeable. Arguably one of the most thorough annual checkups I have had since being in the home for 7 years and using some other services in the past. While both furnaces are well beyond their expected life, neither tried to "oversell" me and offered objective pros/cons to some repair options vs. replacement. I would highly recommend One Hour Heating & Conditioning."

"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"Customer service was excellent. Everyone from the person who first answered the phone to the guys who did the cleaning were friendly, professional, courteous, and thorough. We can tell the difference in the air quality already and our furnace sounds quieter too."
