Trusted By Our Community
When our AC failed during that brutal July heatwave, Onyx had a technician to our Ahwatukee home in under two hours. Carlos diagnosed a failed capacitor and had us cooling again before sunset. His professionalism and knowledge of our older system were impressive.
The team installed a new Trane system in our Chandler home with minimal disruption. They took time to explain the sizing calculations and why their recommendation differed from other bids we received. Six months later, our energy bills are noticeably lower and cooling is more consistent throughout the house.
Our 1980s Mesa home always had hot and cold spots until Onyx sealed our ducts. They used some special camera to show us all the leaks, and the difference was immediate. Our upstairs now stays comfortable all summer, and we're saving about $40/month on electricity.
As a snowbird, I appreciate that Onyx does a thorough preseason check on our Scottsdale condo every November. They send detailed reports with photos so I know exactly what shape the system is in before we arrive. Their reminders for filter changes back east are a nice touch too.
Our Gilbert home's heat pump wasn't performing well last winter. The Onyx technician spent hours recalibrating the system and explained how to use the emergency heat strips properly for our climate. Now it works perfectly in both heating and cooling modes.
The Ecobee installation in our Tempe rental property was flawless. Onyx programmed it with our tenant's schedule and showed them how to use all the features. We've already seen a 12% reduction in cooling costs compared to last summer.
