❌ 1. Choosing the Wrong Size System
This might be the most frequent—and expensive—mistake we see. Many homeowners assume that “bigger is better,” but when it comes to HVAC installation Houston, an oversized unit will cool your home too quickly without properly dehumidifying it. On the flip side, a unit that’s too small will run constantly and still struggle to cool your space.
How We Help:
At 75 Degree AC, we perform detailed load calculations to recommend the right size system—ensuring energy efficiency, optimal comfort, and longer system life.
❌ 2. Hiring Unlicensed or Inexperienced Installers

What to Look For:
Always check for certifications, insurance, and experience with residential and commercial AC installation Houston. We proudly stand behind our team’s licensing, training, and decades of combined experience.
