HVAC Before & After in Miami, FL

You can read about a company’s standards all day, but there’s no substitute for seeing the work. In Miami’s heat and humidity, a clean installation is not vanity, it’s long-term performance. We keep a project record because duct lines, drain runs, and equipment placements tell the real story. Here are representative jobs we’ve completed across Miami, the kind of work our technicians do every week.

Recent Transformations

Split AC System Replacement in Coconut Grove

BeforeAfter

The old 2.5-ton condenser was original to a 1998 build, sitting on a rusted pad and wired with corroded disconnects. We removed the entire outdoor setup, poured a new level pad, and installed a matched 3-ton condensing unit with new line set covers. The homeowner now holds a written price that matched the final invoice to the dollar, plus the 365-Day Done Right Promise on the full installation work.

Attic Furnace Swap in a 1950s Morningside House

BeforeAfter

Miami attics get brutally hot, and this furnace had a cracked heat exchanger, a failed blower capacitor, and enough dust layered on the coil to make any technician pause. We pulled the old cabinet, rehung the new unit with proper vibration isolation, and replaced the flex duct connections that had been leaking into the attic. The homeowner’s written quote came before a single tool came out, and the work is covered for a full year.

Clogged Drain Pan and Emergency AC Repair in Kendall

BeforeAfter

Water was staining the ceiling below an air handler closet, and the system shut down on a float switch over a weekend. We arrived, cleared a fully blocked condensate line, replaced the rusted drain pan, and added a safety overflow switch wired to the thermostat. The repair price was written down before work started, and the whole repair is guaranteed for 365 days. If the same issue reappears within that window, we come back and correct it at no charge.

Wrong-Size AC Unit Replaced in Little Havana

This bungalow had a 2-ton unit trying to cool roughly 1,500 square feet through poorly sealed ductwork. The old condenser ran constantly, and the indoor temperature never dropped below 78 on summer afternoons. We performed a full load calculation, sealed the accessible supply plenum, and installed a properly sized system with a new thermostat. The unit cycles normally now, and the homeowner has a written guarantee in hand.

Rooftop Package Unit Repair in Brickell

A commercial-style package unit on a Brickell low-rise had a failed compressor and a refrigerant leak at the service valve. We recovered the remaining refrigerant, replaced the compressor and filter drier, pressure-tested with nitrogen, and pulled a proper vacuum before recharging. The written price included labor, parts, and refrigerant, and the repair is backed by the 365-Day Done Right Promise.

Ductwork Repair and Airflow Correction in Westchester

Two rooms never cooled properly, and the homeowner had been told by another company the system was simply undersized. We found a collapsed return flex duct in the chase and a supply run that had separated at a junction. After replacing the damaged sections with properly supported duct and sealing the connections, static pressure dropped and airflow to the problem rooms tripled. Another repair covered in writing for a full year.
