Our Story

Greenleaf Mechanical Services started from a reason to overhaul how companies should really treat their clients. We strongly believe against old hard-sell tactics, which creates a stress-free environment for the client and us. While doing services in your home, we will never upsell you, but we will give recommendations from time to time, depending if system is not up to code or would be beneficial for your health. We are a small business, and not a franchise. With a franchise comes a hefty overall ticket, even though initial service call might be cheaper.
