About Us

Avalanche Air started as a small, one-truck, one-employee Los Angeles HVAC company. Now, we occupy a beautiful office, have a state-of-the-art warehouse, a fleet of trucks, and employ a dedicated team of knowledgeable professionals. We did this by sticking to a simple set of rules:

  • 1. Do it right the first time.
  • 2. Finish within budget and on time.
  • 3. Build relationships that last.

Avalanche Air builds custom solutions for every HVAC need, with experienced crews for non-prevailing wage as well as prevailing wages. Our HVAC professionals are the first to know about new techniques, standards, and equipment specializations with special courses and training made available through our close relationship with manufacturers.
