What Sets Our HVAC Installation Service Apart
A new HVAC system is one of the most important investments you can make in your property. THA installs complete heating and cooling systems for residential and commercial clients, working with top brands including Carrier, Bryant, Trane, and Goodman. Every installation is sized using a load calculation so you get maximum efficiency without paying for excess capacity. San Diego's varied microclimates, from the marine layer in La Jolla and Ocean Beach to the warmer inland zones of El Cajon and Santee, mean system selection genuinely matters. We recommend solutions built for your specific conditions, whether a high-efficiency central AC, a heat pump, or a ductless mini-split for homes without existing ductwork.
How Does the HVAC Installation Process Work?
Our process is straightforward from the first call to final inspection.
- Free estimate and site visit, a technician reviews your space, ductwork, insulation, and cooling load to recommend the right system.
- System selection, we walk you through brands, efficiency ratings, and financing options.
- Permit coordination, we pull the required mechanical permit through the City of San Diego Development Services Department on your behalf.
- Professional installation, our C-20-licensed technicians handle all equipment, refrigerant, and duct connections to California Title 24 standards.
- Testing and inspection, we verify airflow, thermostat operation, and refrigerant levels before sign-off.

Every HVAC installation in San Diego requires a mechanical permit. Skipping this step can create problems at resale and may void equipment warranties. As a C-20-licensed contractor, THA handles permitting, HERS verification coordination, and final inspection so you never navigate the process alone.
