  Had an ancient (like as old as the house which was built in the 60s!) wall furnace in my mother's home that stopped working after we had some kitchen remodeling done. With winter coming along I wanted to see if the antique worked and asked for some quotes from nearby businesses on Yelp. Certified was one of the first to respond and also provide availability within the week. I spoke with Mark on the phone and got details on the service fee ($69 flat and waived if I went with service) and they recorded more details to prepare for the visit. Super friendly and I felt good with going with them when I spoke with Mark on the phone. The day of the visit I received a call and text when my technician, Lucas, was going to arrive. The text even included a picture of Lucas so I would know who to look out for which I appreciated! Even though I was quoted 30 minutes for arrival Lucas came within 15 minutes of the notice. First impressions of Lucas was that he's respectful, professional and polite as he wore a mask and shoe covers in the house. With how ancient my furnace was, he was very honest from the beginning that he wasn't sure if he would be able to fix the issue and that replacement parts would be more costly than a new unit. However, miraculously, Lucas was able to get the heater working again! He took his time to explain everything carefully and answered all my questions no matter how simple (like which way the knob goes for the fan to kick in automatically). Lucas even took his time to carefully test the area for carbon monoxide. I really appreciate the whole Certified team for such outstanding, honest, professionalism from start to finish and will definitely recommend them to anyone!!

  I am very impressed with Certified as a whole company. We had our whole HVAC system replaced. Efficiency would be a good work describe the process. From the quote given to us by Lucas. To the four technicians Wyatt, Christian, Joshua, and Josh. Everything went smooth and as promised. Installation was complete in one day. Highly recommended!!!

  Luis and Joshua were here today to install our new HVAC. They were incredibly courteous and professional, and did a phenomenal job. Absolutely every piece of equipment they removed was taken off-site, and you'd never be able to tell any work happened based on how clean the work area is now. When setting up a quote with Certified, Stephen was EXTREMELY helpful and knowledgeable. When it came time for permitting, Brittany was an absolute pleasure to speak with and took her time in explaining what she was doing to both me, and my curious children. 5 stars. 10 stars. HIGHLY RECOMMEND!
