The price depends on your home’s size, the complexity of the install, and whether you add compatible Infinity system components. While it costs more upfront than standard models, the long-term energy savings and added smart features justify the investment for many homeowners.

Customer Feedback

Reviews from Carrier customers often highlight the quiet performance and noticeable energy savings:

“Hard to beat the best HVAC system ever manufactured. This system has it all… I would purchase it again!”Verified Buyer

“Extremely Quiet! You have to be standing at the unit to know if it’s running or not. If it hasn’t been running for a while, the fan inside the house will come on to balance the temperature and verify if it needs to come on. At 26 seer, and variable speed, it’s extremely economical to operate.”Verified Buyer
