Air Conditioning & Heating Service
Miami Lakes was planned around its lakes and its ductwork mostly runs through hot attics rather than through conditioned space. That is where the capacity goes. Before anyone talks about a bigger system, it is worth finding out how much of the current one is being lost overhead.
Free estimate on replacement. Call or send the form.
Monday to Friday 8 AM to 5 PM and Saturday 9 AM to 2 PM, Miami time. We are closed on Sunday.





Miami Lakes was planned rather than accumulated, and it shows: the streets curve, the lakes are deliberate and the tree canopy is mature. That canopy is pleasant to live under and hard on outdoor equipment. Leaf and seed litter packs condenser fins tightly, and a coil that cannot shed heat pushes head pressure up until the system either loses capacity or trips out.
We clean a lot of coils here. You can tell how a summer went by how much comes out of one.
Given the tree cover, twice a year is the sensible rhythm here, with the outdoor coil washed properly each time rather than sprayed from a distance. We also check that the condenser has its manufacturer clearances, because mature landscaping tends to close in on equipment over the years without anyone noticing.
Beyond the coil wash, a tune up reads the refrigerant charge against the manufacturer's target, checks amp draw on the compressor and blower, treats the drain line and tests the capacitor before the first hot week finds it. On a shaded lot that work is the difference between a system that reaches fifteen years and one that does not.
Water everywhere means latent load everywhere. A system sized generously for the square footage cools the air quickly, shuts off and never runs long enough to remove moisture. The thermostat is satisfied and the house still feels damp. That is a sizing and run-time problem, and the answer is usually a correctly matched system rather than a bigger one.
When a system does reach the end here, we size the replacement for the humidity rather than for the square footage.
The useful work is run time and moisture control, not a duct cleaning. We measure indoor humidity across a day before recommending equipment.
A hot attic takes the capacity before the room ever sees it, which is why the places a house leaks air belongs in the same conversation.
The system is satisfying the thermostat before it has removed any moisture, usually because it is oversized for the load. Sizing for the latent load rather than the square footage is the answer.
Indirectly. It loads the outdoor coil, the system loses capacity, run times get erratic and the moisture never comes out. Washing the coil properly does more for the indoor air than it sounds like it should.
Not in this climate. Continuous fan re-evaporates the moisture sitting on the coil and pushes it back into the house, which is the opposite of what you want here.
