The short version of this page: Miami-Dade County runs to 1,900 square miles, its weather is the record kept at HOLLYWOOD NORTH PERRY AP, FL US — 121 heating degree days, 4,640 cooling degree days — and its systems live under a humid pressure. One call to TempReach USA, a referral service rather than an HVAC company, connects you with an independent local HVAC technician serving the county.
Every climate number on this page comes from one record: the NOAA 1991-2020 normals at HOLLYWOOD NORTH PERRY AP, FL US, the primary metro's station, read here for Miami-Dade County. The record's shape is 121 heating degree days set against 4,640 cooling degree days, 61.98 inches of precipitation in an average year, 105.1 days reaching 90 degrees or above and 0.0 nights at or below freezing, with an average temperature of 77.3 degrees across the year.
Read Miami-Dade County's humidity through its calendar and a pattern emerges: the wettest weeks and the hottest weeks are neighbours, so the condensate drain, the coil and the blower are all examined by peak load at the same time, across every community in the county at once. That overlap is the humid profile's real pressure — not heat alone, not moisture alone, but both arriving together over 1,900 square miles, 105.1 hot days a year, with no dry season long enough for a neglected system to hide in.
One more county fact belongs in the record: position. Miami-Dade County sits at 25.616009, -80.50375 on the map — the centroid of a county whose communities spread across 1,900 square miles of Florida. Position decides which end of the metro's weather arrives first and which of its service patterns a household here meets most; the rest of this page is that position, read through the climate record and the metro's data.
A ZIP code in Miami-Dade County is a small climate-and-housing district of its own. The county's 80 codes — 33010, 33012, 33013, 33014 among them — all read the same normals from HOLLYWOOD NORTH PERRY AP, FL US, yet the systems inside them were installed in different decades, serve different house sizes, and fail in different orders. That is why this page prints the whole list rather than a summary: the codes are the finest division of the county the data supports, and they are the division the work itself follows.
Position first: Miami-Dade County lies south of the Miami metro's centre, roughly 37 miles from the metro's centre as the map measures it, with Broward County, Palm Beach County among the counties around it. Neighbourhood at county scale matters to heating and cooling because systems do not respect the border — the same subdivisions' building decades continue across it, the same cold snaps and heat waves examine both sides in the same night — while each county's page, this one included, keeps the local figures distinct.
A year in Miami-Dade County, counted the way a technician counts it, is not twelve months but two workloads and the weeks between them. The first workload is written as 4,640 cooling degree days, the second as 121 heating degree days; 61.98 inches of precipitation fall across both, and the average temperature of 77.3 degrees is simply the figure the two workloads leave behind when they are averaged. The county's humid pressure is whichever workload the count puts first — and the maintenance year is arranged around that ordering.
Communities across Miami-Dade County include Miami, Hialeah, Miami Gardens and its remaining communities — 3 listed places in all, spread over the county's 1,900 square miles in Florida. Each community's housing was built in its own decades, so the heating and cooling diary reads differently from one name on that list to the next: older systems and original ductwork in the long-settled places, matched fleets ageing together in the subdivisions, and additions and conversions in the communities still growing at the county's edges.
The county's position frames its housing as well. Miami-Dade County lies south of the Miami metro's centre, roughly 37 miles out, and the metro's era mix — 32.8% built between 1980 and 1999, 31.9% between 1960 and 1979, median year 1982 — reads at this distance with a county accent: the shares nearer the centre and the shares at the edge were platted in different decades of the metro's growth. Which band a given Miami-Dade County street belongs to is a local fact; that the bands exist, in these proportions, is the Census record this page is built on.
There is a reason the coverage on this page is described county-first. Heating and cooling demand is generated house by house, and houses sit in counties: in Miami-Dade County's case, across 1,900 square miles that hold 3 listed communities and 80 ZIP codes, south of the Miami metro's centre. The metro frame matters — the station, the housing eras, the problem ranking all come from it — but the county is where the frame touches the ground, and the ground is where the systems are.
City pages carry the metro-wide homework — housing eras, the problem ranking, services in depth. This county sits inside their coverage.

TempReach USA is not an HVAC company. We employ no heating or cooling technicians, we run no service trucks, and we do not carry out HVAC work of any kind. This website and its call center exist for one purpose: to connect homeowners with independent local heating and cooling professionals who serve their area. When you call the number on this site, your call is routed to such a professional. From that point, everything about the job belongs to that professional and to you: the assessment, the work itself, the scheduling, what you are charged, and the terms of any agreement you reach. The professional who takes your job is solely responsible for it. The technician who arrives at your home runs their own business; they are not an employee, agent or subcontractor of TempReach USA. Our part is the information on these pages — assembled from Census Bureau housing data and NOAA climate records for each metro — and the routing of your call. We state this plainly on purpose: you should know exactly who you are hiring before anyone picks up a wrench or a gauge.
One call connects you with an independent local heating and cooling professional serving Miami-Dade County and the Miami metro.
