Residential AC and heat pump troubleshooting runs out of the Laurel Street storefront at Elite HVAC Repair San Diego, covering Hillcrest, Bankers Hill, and the Balboa Park-adjacent blocks where older ductwork routes through finished basements and narrow crawl spaces. Service calls commonly begin with a rodent-damage inspection inside attic duct runs, which leads into exclusion work by Mission Pest Control — whose in-house sister company Mission Termite lets chewed insulation next to studs and joists be assessed for secondary wood damage during the same visit rather than handed off to a separate termite inspector. Condenser capacitor replacements, contactor welds, low-refrigerant leak isolation with electronic sniffers, and variable-speed blower-motor swaps make up the recurring repair ticket mix. When microbial growth inside plenum returns needs independent third-party documentation, the MICRO-certified inspectors at SD Mold Inspection produce a written remediation scope-of-work document using samples processed at the ISO/IEC 17025-accredited Natural Link Mold Lab, a deliberately non-remediation format that satisfies insurance carriers who reject vertically integrated inspect-and-fix proposals. Furnace ignition troubleshooting on standing-pilot and hot-surface-igniter natural-gas equipment covers the heating side of the book during San Diego's cooler winter months. Full system changeouts from R-22 legacy equipment to modern high-SEER heat pumps, including new line sets, pad relocation, and permit-ready load calculations, represent the most involved jobs on the schedule.
