Miramar is really two cities for air conditioning: the original blocks of Historic Miramar in the east and the two-story subdivisions that spread west toward I-75. Each has its own problems, and we handle both.
AC repair in Miramar depends a lot on which side of the city you live on. In west Miramar, communities like Riviera Isles, Monarch Lakes, Silver Falls, Sunset Lakes and Vizcaya are mostly two-story homes and townhomes built in the late 1990s and 2000s, often with an air handler in the attic or a second system for the upper floor. Historic Miramar, in the east, has smaller single-story block homes from the city's early decades, and the middle of the city adds the apartments and condos around Miramar Town Center.
Heat rises, so in a two-story house the upstairs bedrooms carry the hardest load, sitting right under a roof that soaks up sun all afternoon. When one system serves both floors, the downstairs often feels cold while the kids' rooms upstairs stay warm. In the older east side homes the trouble is age instead: equipment and wiring that have been through many Florida summers and duct runs patched more than once.
A common Miramar call is a water stain spreading on a ceiling, because when the air handler lives in the attic a clogged condensate drain or a rusted pan leaks straight down onto the drywall below. Others are an upstairs that will not cool, a system that starts and stops every few minutes, and an outdoor unit that has gone quiet with the fan still turning. Systems from the 2000s building wave are now old enough that capacitors, fan motors and coils start to fail one after another.
Many west Miramar homes are now reaching their first full replacement, and it is the moment to fix what the builder got wrong. A single oversized unit can cool a downstairs fast and still leave the upstairs muggy, so we look at splitting the load into two systems or adding zoning, and at higher SEER equipment that trims the runtime on a big house. In a Historic Miramar home the goal is usually simpler: a properly sized, efficient system that fits the existing space.
Upstairs comfort in these homes often comes down to the ducts as much as the equipment. Long runs to the second floor that are undersized, crushed or leaking in a hot attic deliver weak, lukewarm air no matter how hard the system works. We redesign or reseal those runs and balance the airflow between floors, and a smart thermostat with a sensor upstairs keeps the system answering to the rooms that actually need it.
KAF has worked on South Florida air conditioning for nearly two decades, and our own licensed crew (CAC 1818942) handles every Miramar job, east side or west. Repairs carry a 30-day labor guarantee, and we work on all the major brands you will find in these homes.

Learn moreIt is usually a mix of three things: heat rising under a sun-baked roof, duct runs to the second floor that are too small or leaking in the attic, and one system trying to serve two very different floors. The fix depends on which one is to blame: the ducts, the balancing, zoning or a second system.
Turn the system off at the thermostat so it stops making condensate, then call us. In attic installs the cause is almost always a clogged drain line, a cracked or rusted drain pan, or a safety switch that has failed. We clear the drain, check the pan and switch, and tell you whether the pan needs replacing so the ceiling does not get wet again.
SEER measures how much cooling you get per unit of electricity over a season, so a higher number means less power for the same comfort. The difference shows most in large two-story homes that run the AC for long hours, as long as the system is sized correctly and the ducts are not leaking that savings into the attic.
Not always. Newer homes rarely have decades of buildup, but construction dust left from the build or from later remodels, and moisture in an attic air handler, can still leave the ducts dirty. If you notice dust from the vents, a musty smell when the system starts or worse allergies, we inspect first and only recommend cleaning if it is needed.
Only if both are at the end of their life. Systems installed together tend to age together, so it is worth checking the second one when the first fails, but if it still has good years left we will tell you so. We give you a free estimate for one system or both, with upfront prices for each option, and the choice stays yours.
Yes, short cycling wears out the compressor and leaves the house humid. Common causes are an oversized unit, a dirty coil or filter, low refrigerant, or a thermostat in a bad spot, such as next to a supply vent or in direct sun. A technician can usually pin it down on the first visit.
"They replaced the motor and the AC was cooling again in under 30 minutes. The techs were polite, fast, and explained everything."
"Asked for a quote and they reached out within an hour, then showed up 30 minutes later. Same-day, professional, and a fair price."
"Virgilio helped us get a new AC unit and saved us money on financing. Honest company that does the work themselves — highly recommend."
No matter what's cooling your home, our technicians know it inside out.
