Why should you trust Omar Jacobo's HVAC advice?
I've been in the HVAC industry for 10 years. I started on the commercial side, spending 3 years installing rooftop units on Amazon warehouses and major DFW commercial projects. Then I switched to residential HVAC full-time, where I've been working directly with homeowners for the past 7 years.
I hold EPA 608 Universal Certification (#2396328), which means I'm authorized to handle all types of refrigerants. My wife Mariafernanda Jacobo holds the Texas HVAC Contractor License (TACLA126718E). Together, we run Frosty's HVAC LLC with 96 five-star Google reviews across 6 DFW cities.
