130 HVAC Maintenance Contractors in San Antonio, TX

HVAC maintenance in San Antonio is more consequential than in moderate climates. With 113 days above 90°F and humidity that keeps latent loads elevated through summer, a system that hasn't been serviced before peak season is running at elevated risk of failure precisely when it's needed most. The city supports 116 maintenance-capable contractors at a 4.8-star average across 72,000 reviews, with half offering flexible or 24/7 scheduling.

Maintenance pricing in San Antonio is straightforward. A single AC tune-up runs $70–$200, a furnace tune-up costs $80–$220, and a full HVAC inspection including both systems falls between $150–$400. Many contractors offer annual maintenance plans that bring per-visit costs down further. Texas requires all servicing contractors to hold TDLR Class A or Class B licenses, so any technician working on refrigerant systems must meet the state's 48-month experience threshold.

Goettl's Jonathan Buhidar appears consistently in maintenance reviews for doing more than the checklist — identifying a refrigerant leak incorrectly installed by a prior contractor during a routine visit, then documenting it rather than billing for a repeat service call. Aramendia Plumbing, Heating and Air receives praise for same-day or within-the-hour dispatch on maintenance calls that surface urgent repairs. Elmer's Home Services draws specific attention for technician coordination: reviewers describe KenShaun and Raul working in synchronized fashion across full-system maintenance visits.
