About this listing
Hercules HVAC Pro is listed in Houston, TX. New split-system air conditioners installed anywhere in Texas must meet a minimum of 14.3 SEER2 under the federal South-region standard — worth knowing when you compare quotes, since a cheaper unit that falls below it cannot lawfully be installed here.
Round-the-clock service: this contractor advertises 24/7 emergency availability on their own website. We have recorded the claim, not verified the hours — confirm someone will actually answer before you rely on it at 2am.
