Cool Atmosphere installed my replacement HVAC in my last house. No issues. One screw up by a new employee was caught by CA before I noticed - and immediately corrected without my engagement. My new house came with a flawed HVAC design. CA came in to audit the issue, made recommendations, implemented them, and my electric bill dropped by $200 for the next three months as compared to the prior year same months. It's nice to work with responsible, competent professionals.
