"One of the best companies at walking you through your options and being honest with you along the way. Of all the folks I brought through to quote our full HVAC replacement, Jeremy was the only one that seemed to "shoot it straight" the most. I never felt like I was needing to cut through the salesmanship to understand if what I was being told was what I actually wanted/needed. Our system was installed in less than a week after we made our decision - which is awesome. The install crew was great and very helpful as they went through the process. We've been going through a bunch of home projects in the last couple years and Harmonic made this one about as painless as I could've imagined. Definitely go with them. "
