“I can not say enough about how the 8 Finger HVAC, LLC team helped me! They installed a beautiful new minisplit in my family room but that was only the half of it! They spent HOURS helping me fight with Lennox about my unit that was "under warranty". They went above and beyond! I highly recommend them!!!!”

“Bobby and his crew are awesome to work with. Very professional, thorough, and willing to answer any questions. Never had a problem with them not responding to calls or showing up on time, unlike some of their competition. Would recommend 8 Finger HVAC to anyone! Keep up the great work!”

“8 Finger did an amazing job of troubleshooting a furnace that had quit running. We ended up replacing the furnace. The installers were friendly and clean. The communication was there, which is important when someone is providing a service on your home. Highly recommend!”
