💧 Another project completed at O-Zone Heating & Cooling!
We designed and installed a rainwater collection system for our building. This was a complex project, and it took a great team to make it happen.
🔨 Ryan Wilson / Wilson & Sons — excavation
🔧 Oswaldo Cardenas Morfin — plumbing
💪 The entire O-Zone team — helped throughout the process.

I’m proud of what we built and even more proud of the team that helped bring the idea to life.
Build it. Improve it. Keep moving forward. 💧🔧

This is what a month and a half of cottonwood exposure can do to your A/C system. 🌳❄️

A clogged condenser coil forces your system to work harder, reducing efficiency and increasing wear and tear.

Don't wait for a breakdown. Schedule your A/C maintenance today!
