About Master Mechanical HVAC Corp
A family-run HVAC contractor serving Miami-Dade & Broward — 24 hours a day.
Our Story
Master Mechanical HVAC Corp was founded by Rider de la Nuez on a simple promise: answer the phone, show up when we say we will, and fix the actual problem instead of the symptom. From day one we have grown by word of mouth across Miami, Coral Gables, Coconut Grove, Doral, and the beaches.
Today we cover Miami-Dade and Broward County — from Key Biscayne and Fisher Island to Pinecrest, Miami Beach, and Fort Lauderdale. We also serve All South Florida beyond our core coverage area — call to confirm. We handle air conditioning, heating, ventilation, cold rooms, and commercial refrigeration, which means one contractor can take care of every system in the building.
We are licensed, insured, and bilingual — hablamos español. Estimates are always free, every system change-out includes a full year of maintenance at no cost, and we answer the phone 24 hours a day. In Miami, an air conditioner that quits on a Saturday night is not something that can wait until Monday.
What We Stand For
Reliability
We answer at 2 AM the same way we answer at 2 PM. When we commit to a window, we show up in it.
Respect
We protect your floors, clean up after ourselves, and explain what we found in plain language.
Quality
Properly sized systems, sealed ductwork, and real commissioning — installed to last, not just to run.
Community
We are a Miami family business. We hire local, we serve local, and we treat customers like neighbors.
Our Mission
Keep South Florida homes and businesses comfortable and running, around the clock, with honest diagnostics and work that holds up. Earn trust one service call at a time.
Our Promise
We tell you the truth about your system — including when a repair is smarter than a replacement. If something is not right, we come back and make it right. That is how we have built our customer base across South Florida.
