Notification of arrival and service was very good. Service was good. Highly recommended for personal and quality service.

Off to a rough start, but they came through and fixed my AC. My family and I greatly appreciate getting us taken care of.

Technician didn't verify ac worked before leaving site. Also lied about charges. Only had one thermostat and technician still was looking for multiple controls

Great service! Great price! They kept in touch during the whole process.

I have really enjoyed the service from SAC. They are reliable and deliver a great value.

With a twenty year old home, we needed an overhaul. I wasn't sure where to start. They gave me reasonable options and installed an AC, furnace, and humidifier without a hiccup. They were professional and thorough.

Aaron, Kevin, Gnnie, and Meghann are all great folks to work with! If it was up to me I would use people like this for all my home services.

SAC always responds in a timely manner with excellent service at a fair price. They consistently exceed my expectations and I highly recommend them!

Incredibly disrespectful of neighbhors. Asked politely when he was at his truck putting tools away if he could move his truck 10 ft forward for a real estate listing photoshoot. He said he was about to leave then went in his clients house for another 10 minutes. I knock on the door ask him hey I really need you to move this truck, and he snapped at me I’m busy!!! Not sure why it was so hard for him to have moved his truck - would’ve taken him 20 seconds and now I lost my photoshoot that I paid for.

SAC installed an April Aire 800 whole house humidifier in our home in Boulder. Their estimate was considerably less than their competition; they were able to complete the install in less than a week after we agreed to hire them. The crew and salesman were all prompt, courteous, knowledgable and easy to deal with - no extraneous marketing or upselling. I would highly recommend them for any HVAC related job and will be calling them the next time we need service in that area.

We had a great experience with SAC Mechanical. The technician was very professional, came to our house on time, a great service overall.
