Warren County heating & cooling, in brief

The short version of this page: Warren County runs to 429 square miles, its weather is the record kept at ST LOUIS LAMBERT INTL AP, MO US — 4,433 heating degree days, 1,713 cooling degree days — and its systems live under a heating 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.

The Warren County climate record

The climate figures on this page are the primary metro's NOAA 1991-2020 normals — climate normals recorded at ST LOUIS LAMBERT INTL AP, MO US, the station for the St. Louis metro this county belongs to. An average year there brings 4,433 heating degree days, 1,713 cooling degree days, 41.7 inches of precipitation, 47.1 days at 90 degrees or above and 84.9 nights at or below freezing, around an average temperature of 57.4 degrees.

Divide Warren County's cold by its coverage and the heating diary sharpens: 6 ZIP codes over 429 square miles, 71.4 square miles per code on average, the codes running from 63351 to 63390. A furnace failure in the code nearest the metro reads differently from one at the county's far edge — not in the fault, which is the same worn igniter or tired blower, but in everything around it: the drive, the house's decade, the odds the system has already been replaced once. The cold itself, 4,433 heating degree days of it, is shared; the ground it is answered on is not.

The county's neighbours frame it as well: St. Charles County, St. Clair County, St. Louis City are among the 14 counties on its neighbour list, and together they form the working ground around Warren County's own 429 square miles. A system near a shared border lives in both counties' weather at once, whichever page describes its home — the pages divide the map so the record can be read county by county, and the links between them keep the whole in view.

Count the coverage from the codes upward: 63351, 63357 and 63380 are the first codes on Warren County's list of 6, spread across its 429 square miles in Missouri. No two of those codes hold quite the same housing — one may be a settled community's streets, the next newer subdivisions, the next open county ground — so the same climate record produces a different run of calls inside each. The full list is printed on this page; the diary is written code by code.

Position first: Warren County lies west of the St. Louis metro's centre, roughly 45 miles from the metro's centre as the map measures it, with St. Charles County, St. Clair County, St. Louis City 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.

The precipitation figure earns its place in Warren County's record: 41.7 inches a year at ST LOUIS LAMBERT INTL AP, MO US, falling through both the cooling months and the heating ones. Rain loads condensate systems in summer, tests outdoor units and venting in winter, and keeps the ground around the county's 6 ZIP codes cycling between wet and dry in a way that shows up in crawl spaces and condensate lines. Set beside 47.1 hot days and 84.9 freezing nights, it completes the picture of what the county's equipment actually lives in.

Communities and housing in Warren County

Some counties on this site are lists of towns; Warren County is a territory. The record gives it 429 square miles, 14 neighbouring counties on the coverage map, and a position west of the St. Louis metro's centre — and its homes are distributed through that territory rather than gathered under place names the record can list. For heating and cooling the consequence is a diary of distance: longer drives between calls, systems of every era met one by one, and local knowledge that lives in roads and addresses instead of in town names.

Ownership writes part of the diary too. Across the St. Louis metro, 70.1% of households own their homes, and owner-occupiers and landlords keep different maintenance calendars — owners tending to plan replacements in the shoulder seasons, rented homes more often meeting their systems at the point of failure. Warren County shares that metro pattern across its 6 ZIP codes and its listed communities, and it shows in the timing of the calls as much as in their content: planned work where the owners live, urgent work where they do not.

One way to hold Warren County in mind is as the local layer of a wider dataset. Above it sits the St. Louis metro, with its Census housing profile and its NOAA station at ST LOUIS LAMBERT INTL AP, MO US. At this level sit the county's own numbers — 429 square miles, 14 neighbouring counties, 6 ZIP codes, 0 listed places — and below it, not published anywhere, sit the individual homes whose systems all of it describes. This page works at the middle level, where the data is still local enough to act on.
