Browse by state
Grouped by climate, which shapes what HVAC systems need most.
Hot and humid
Long cooling seasons with heavy moisture. Air conditioners and heat pumps run most of the year, and humidity control matters as much as temperature.
Hot and dry
Extreme summer heat with low humidity. Systems are sized for very high outdoor temperatures, dust loads coils and filters, and evaporative coolers still serve many older homes.
Mixed and humid
Real summers and real winters. Most homes have central AC plus a gas furnace or heat pump, and both seasons bring peak demand.
Mild marine
Cool, damp winters and dry summers that have grown hotter. Many homes were built without AC, so heat pumps and ductless systems are a common upgrade.
Cold
Heating dominates the energy bill. Gas furnaces and boilers are the norm, with summer AC and growing use of cold-climate heat pumps.
Very cold
Long, severe winters where a heating failure can freeze pipes in hours. Furnaces, boilers and propane or oil systems are common in rural areas.
How service areas work
Contractors choose the ZIP codes they serve. When you call, you are connected with a contractor whose area includes your ZIP. If no one covers it, we tell you.
What changes from place to place
Climate drives the work: AC capacity in the desert, humidity control on the Gulf Coast, furnace reliability in the North, heat pump retrofits in the Pacific Northwest.
Licenses and permits
Some states license HVAC contractors statewide; others leave it to cities and counties. State pages explain where to verify a license, and most replacements need a local permit.
