How Retrofit HVAC Installs Qualify
You may be curious about what an HVAC retrofit entails. An HVAC retrofit refers to the process of upgrading or modifying an existing HVAC system to enhance its energy efficiency and performance without completely replacing the entire unit. In simple terms, it means improving your old system to meet current standards while avoiding the need for a full system replacement.
Home Comfort Alliance is happy to check out your HVAC system to see if it qualifies for a retrofit and will meet SEER/HSPF efficiency standards, which in turn will meet
current utility rebate requirements. Email us at info@homecomfortalliance.com for a fast assessment.
