2,044 ZIPsCalifornia
California is two HVAC markets in one: mild coastal zones where heat pumps and ventilation rule, and scorching inland valleys — the Central Valley, Inland Empire, high desert — where summer cooling loads are among the nation's highest. Wildfire smoke has made high-filtration systems and sealed ductwork a selling point statewide, while older housing in Los Angeles and the Bay Area still runs on aging furnaces and wall heaters.

1,562 ZIPsTexas
Texas cooling loads are brutal — long summers in the triple digits across Dallas, Houston, and San Antonio keep air conditioners running for months, and Gulf humidity forces systems to dehumidify as well as cool. The flip side is winter: deep-freeze events burst pipes and kill heat pumps statewide, so cold-climate performance now matters in bids. Hail season also chews up condenser coils and outdoor units across North Texas.

1,374 ZIPsFlorida
Florida is the country's most cooling-dominated market: year-round heat and humidity mean air conditioners rarely rest, and undersized or aging systems show it in both comfort and electric bills. Salt air corrodes condenser coils within sight of the coast, and hurricane season punishes outdoor units with wind-driven debris and storm surge.

1,360 ZIPsNew York
New York City's pre-war walk-ups and tenements still run on steam and hot-water radiators, while the suburbs wrestle with oil-to-gas conversions and aging furnaces. Upstate, lake-effect winters from Buffalo to Syracuse deliver some of the heaviest heating loads in the country, and summer humidity in the Hudson Valley keeps air conditioning busy too.
Local guide →1,288 ZIPsPennsylvania
Pennsylvania is heating country with a humid-summer kicker: long winters drive furnace and boiler demand in Philadelphia rowhouses and Pittsburgh's hillside housing, while July humidity makes air conditioning a must across the southeast. Much of the housing stock predates central air, so ductless mini-splits are a common retrofit.

932 ZIPsOhio
Ohio swings hard both ways — humid summers that punish weak air conditioners and long, cold winters that keep furnaces running for months in Cleveland, Columbus, and Cincinnati. Rust-belt housing with original ductwork and aging equipment makes system replacement, not repair, the common call.
Local guide →850 ZIPsNorth Carolina
North Carolina's Piedmont summers are hot and humid enough to make air conditioning non-negotiable, while mountain winters around Asheville bring real heating loads and freeze risk. Rapid growth means many homes run builder-grade systems that age out fast, and coastal humidity plus salt air wear on equipment in the east.
Local guide →810 ZIPsIllinois
Illinois is a furnace state first: Chicago winters are famously brutal, and heating systems in the city's vintage housing and suburbs run hard for half the year. Summers bring humid heat waves that test air conditioners, and lake-effect microclimates keep technicians busy on both ends of the thermostat.
Local guide →792 ZIPsIndiana
Indiana pairs humid Midwestern summers with genuinely cold winters, so most homes need both solid cooling and reliable heating — heat pumps with backup heat are a common setup. Indianapolis freeze-thaw cycles punish outdoor equipment, and older housing across the state still runs on aging furnaces.
Local guide →720 ZIPsNew Jersey
New Jersey's dense suburbs and Shore towns get humid summers that demand real dehumidification, plus nor'easter winters that keep boilers and furnaces working in older Capes, colonials, and split-levels. Salt air along the coast corrodes outdoor units, and tight lots make equipment placement a puzzle.
Local guide →630 ZIPsGeorgia
Georgia summers are long, hot, and humid — Atlanta's cooling season runs from spring deep into fall, and humidity control matters as much as temperature. Pollen season clogs filters and coils statewide, and older homes with original ductwork leak conditioned air into crawlspaces and attics.
Local guide →605 ZIPsMassachusetts
Massachusetts is boiler and furnace country: triple-deckers and colonials with some of the oldest housing stock in America, heated through long winters by oil, gas, and steam systems. Summers are shorter but humid enough that air conditioning — often ductless retrofits — has become standard.
Local guide →577 ZIPsTennessee
Tennessee summers are hot and sticky from Memphis to Knoxville, pushing air conditioners to their limits, while winter ice storms and cold snaps test heat pumps and furnaces. Tornado-season storms knock out power and damage outdoor units, and fast-growing suburbs run lots of builder-grade equipment.
Local guide →528 ZIPsVirginia
Virginia straddles climate zones: humid Tidewater summers with salt-air corrosion on coastal equipment, hot Piedmont summers around Richmond, and real winter heating loads in the Shenandoah Valley and Northern Virginia. Many homes need both strong cooling and reliable heating.
Local guide →528 ZIPsMichigan
Michigan winters are long and punishing, making furnaces and boilers the heart of every home from Detroit to Grand Rapids — and lake-effect snow buries outdoor equipment for months. Summers are shorter but humid, and aging housing stock means many systems are decades past their prime.
Local guide →520 ZIPsAlabama
Alabama is deep in the cooling belt: long, brutally humid summers from Birmingham to Mobile keep air conditioners running nearly year-round, and dehumidification is half the battle. Gulf hurricanes batter outdoor units on the coast, and winter cold snaps expose heat pumps that were sized for cooling only.
Local guide →498 ZIPsMaryland
Maryland gets the worst of both: humid Chesapeake summers that demand serious cooling and dehumidification, and winters cold enough to keep furnaces and heat pumps working in Baltimore rowhouses and DC suburbs. Salt air affects equipment near the Bay, and freeze-thaw cycles wear on outdoor units.
Local guide →471 ZIPsKentucky
Kentucky summers bring Ohio Valley humidity and heat that keep air conditioners busy, while winters deliver ice storms and cold snaps that test furnaces and heat pumps. Older housing in Louisville and Lexington often has original ductwork and aging equipment.
Local guide →462 ZIPsSouth Carolina
South Carolina is among the hottest states for cooling load — Columbia's inland summers are relentless, and Lowcountry humidity around Charleston makes dehumidification critical. Salt air and hurricanes punish coastal equipment, while mild winters still bring occasional freeze risk to heat pumps.
Local guide →457 ZIPsWashington
Washington is a tale of two climates: mild, marine western cities where heat pumps shine — but wildfire smoke season has made high-filtration systems essential, and heat waves push cooling into homes that never had it. East of the Cascades around Spokane, summers are hotter and winters bring real heating loads and snow.
