A new air conditioner is one of the largest purchases you will make for your home — and in Miami it will run harder than almost anywhere in the country. David Solutions Air Conditioning sizes every system with a load calculation, inspects your ductwork before quoting, and installs Carrier, Trane, Goodman, Rheem and other major brands, with a free in-home estimate and financing for qualifying installations.
Most installation problems we are called to fix are not equipment problems — they are sizing problems. An oversized unit cools the air fast, shuts off, and never runs long enough to pull moisture out. The result is a house at 74°F that still feels sticky, with mold risk in closets and ducts. An undersized unit runs non-stop in August and still can’t keep up.
Before we recommend any system, we complete a load calculation CLIENT CONFIRMATION REQUIRED — confirm Manual J or equivalent that accounts for your square footage, insulation, window area and orientation, ceiling height and number of occupants. The tonnage comes from that calculation — not from what was installed last time, and not from a rule of thumb.
We look at the existing equipment, the air handler location, the electrical service, the condensate drain route and the ductwork — including attic runs and the plenum that most quick quotes ignore.
You receive a written quote with clear options at different efficiency and price levels, and a plain explanation of what you gain by spending more — or why you don't need to.
AC replacements in Miami-Dade require a mechanical permit from the local building department. We handle the permit and schedule the work to keep the time you are without cooling as short as possible.
Old equipment is removed and disposed of properly, refrigerant is recovered, the new condenser is set level and secured to its pad, line sets are cleaned or replaced, and the system is evacuated and charged to the manufacturer's specifications.

The standard for most Miami homes: an outdoor condenser paired with an indoor air handler and coil. We match indoor and outdoor components so the system performs as rated.
A heat pump cools exactly like an air conditioner and also gives efficient heat on the handful of cool nights Miami gets each winter.
Ideal for additions, converted garages, older homes without ductwork, or rooms that never cool properly.
If only one half of the system has failed, replacing just that half is sometimes possible — but compatibility and refrigerant type matter. We tell you when it makes sense and when it doesn't.
For most Miami homes, a complete central AC installation runs from about $5,500 to $12,000 or more, depending on system size, efficiency rating, brand, and how much ductwork, electrical or structural work the job needs. Single-zone ductless mini-splits typically start around $1,500–$3,000 installed.

Most straightforward replacements are completed in one day. Installations that involve ductwork changes, relocating equipment or adding a new system can take two to three days.
Only a load calculation answers that accurately. As a rough reference, many 2,000 sq ft Miami homes land between 3.5 and 4.5 tons, but insulation, windows, sun exposure and layout can move it significantly.

With regular maintenance, most central systems in Miami last around 10 to 15 years. Coastal salt air and skipped maintenance shorten that.
No. The federal 25C credit ended for equipment placed in service after December 31, 2025. Ask us about any current utility or manufacturer promotions when we visit.
Yes, for qualifying installations terms. We explain the options during the free estimate.
Yes — single-zone and multi-zone systems for additions, garages, older homes and problem rooms.
