How we earn trust
UCBM HVAC is a locally operated HVAC company serving residential and commercial clients across the Dallas–Fort Worth area.
Most of our work comes from referrals — homeowners who call us back, business owners who expand with us, and property managers who want consistency across every job.
That trust is earned on job sites: showing up on time, diagnosing correctly, and recommending what actually makes sense.
Experience that shows up on site
Over the years, we've completed hundreds of system installations and handled thousands of service calls — from single-family homes to offices, restaurants, and commercial facilities.

How we approach every job
Diagnostic First
We start by finding the real cause of the problem. If something doesn't need to be replaced, we'll tell you.
Clear Explanations
We explain what's happening in plain language, so you can make informed decisions without pressure.
Long-Term Thinking
We make recommendations based on system longevity and performance — not short-term fixes that lead to repeat problems. Our goal is to reduce breakdowns, not create future service calls.
The people behind the work
UCBM HVAC is led by Jun Kim and Sean Jung, who oversee every project from diagnostics to final quality checks.
We work with a small, trusted team — not rotating crews. When you work with UCBM, you work with people who are accountable for the results.
