SAC Mechanical Heating & Air Conditioning

We just had a service call for a water heater issue and SAC went beyond our expectations by responding with a quick and high quality oriented solution. We have used them in the past for heating and A/C equipment issues and installations and have had a similarly excellent experience. I recommend them without any reservations.

So Zach is the go-to guy if you want a furnace and A/C installation done quickly, professionally and with an incredible attitude! He worked all day and was incredibly friendly, knowledgeable and answered every question I had. He cleaned up after himself and explained how the unit worked so I could handle anything that might pop up in the future. I would highly recommend SAC Mechanical for all your heating/cooling needs... and request Zach to do the install!!

SAC has provided HVAC services at my home for over a year, and they've impressed me with their conscientiousness and customer support. In particular, their technician, Nate, is nothing short of outstanding. He has been professional, knowledgeable, courteous, friendly, dependable and responsive. He and SAC have been a sincere pleasure to work with.
Good job, Nate and SAC. Keep up the great work!

Being in the property management business (All County Boulder Property Management Team) , I work with SAC Mechanical and their amazing staff often on a daily basis. They have extremely knowledgeable technicians that are great to work with and are quick to get us information when needed. I am also using them to work on my own home as well. I would recommend them to everyone!

SAC repaired my residential A/C roof top coil summer 2015. Other Boulder HVAC companies tried to sell entire A/C unit replacement (including costly crane installation to roof) as they informed me that unit was out of warranty. SAC was able to get part under warranty and got the job done on time at a reasonable cost.

Recommended SAC to friend for her home A/C replacement and she was satisfied with installation and cost.

SAC mechanical was able to get a technician team out to my house the same day I requested service. At peak season, that's quite a rarity in this industry. Thank you Rich and Tim for restoring my old unit to its former glory, and at a decent price!

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.

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.

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
