“I got my home’s seventy-year-old ductwork replaced, and everyone at Samm’s did a great job. The whole team is professional, punctual, and considerate. Marcus, who designed our new ductwork, seemed very knowledgeable about HVAC systems (more so than other companies we have used!) and helped us create ductwork that is ideal for our home as it is and with an eye to future plans of adding a second floor. Felipe and his crew kept things as neat as possible during the three days of work and were mindful of my small children and my dog. This is definitely going to be our HVAC crew moving forward.”

“We've been using Samm's every year for routine inspection & checkups since 2012 when they replaced my entire Heating and AC unit. Their professionalism and customer service has never waivered. Every tech has been kind, respectful, and knowledgeable. Our most recent experience with Dillon was no different. He quickly diagnosed the issue and had us back up and running fast. It's rare to find a company that consistently delivers high quality across the board and continues to earn my business.”

“Found that my air conditioner was not working and called Samm's at 4:50. They were still able to help and Tyler was dispatched. He arrived promptly and began working. Found two blown parts and had me back up and running quickly. Tyler was very professional, courteous and knew what he was doing. Best service team ever.”

“We came home after being out of town to a warm house. We got the unit to reset, but knew something else was wrong. I had previously used their services when our heater went out this past winter, so I gave them a call. They offer quick turnaround when scheduling and friendly service. Tyler came out and explained what was happening. He even said he was actually excited to clean our outside unit! Within an hour, our home was cooling so well that we turned up the thermostat. While he was here, Tyler found another issue with the unit in our attic and noted there was some growth in the plenum. They were able to get us on the schedule two days later to take a look at replacement options. Emilio stopped by this morning, and I was honestly shocked at the cost — it was much lower than I expected after doing some research. Samm's Heating and Air offers very reasonable prices and thoroughly explains what is needed. I'm happy to have found their company and will gladly recommend them to anyone in the future.”

“Replaced my 30-year old A/C with Samm’s and they did a great job, from quote to installation complete within 2 days. They were experienced, organized and clean. Emilio who gave the quote came and checked on the work and Jonathan led the crew. Overall very glad to have a working unit before summer heat and at a fair price! Would recommend Samm’s!”
