In brief: 588 square miles of Iowa, a climate read from DES MOINES INTL AP, IA US's normals, and a heating pressure as the county's dominant one — 6,178 heating degree days set against 1,070 cooling degree days in an average year. TempReach USA does not do the work itself; it is a referral service, and one call connects you with an independent local HVAC technician serving Dallas County.
One record, one county: the normals at DES MOINES INTL AP, IA US — 6,178 heating degree days, 1,070 cooling degree days, 36.55 inches of precipitation, an average temperature of 50.9 degrees — applied to Dallas County's own 588 square miles and its 13 ZIP codes. The figures are the Des Moines metro's; the ground they are applied to, lying northwest of the Des Moines metro's centre, is this county's alone, and this section reads the two together.
Read the climate record and the county's pressure names itself. Heating degree days outnumber cooling degree days at DES MOINES INTL AP, IA US, and the lived version of that statistic is a housing stock whose furnaces and heat pumps run the long season while its cooling takes the short one. Across Dallas County's 588 square miles — from Waukee to the county's edge communities — the pattern repeats: systems sized for the cold, maintained for the cold, and replaced, when their time comes, with the cold in mind first.
The county's ground shapes the work in one more way: 588 square miles is a lot of roofs for a service map to hold, and Dallas County's homes divide between its listed communities — Waukee — and the roads between them. A technician routed here is working a county, not a street: the drive between calls is part of the diary, and the systems at each end of it were fitted in the decades those communities were built.
The ZIP list is the county's working map. Dallas County carries 13 codes, running from 50003 through 50146 in the middle of the list to 50323 at its end, and every code on it is a small housing census of its own — the building decades, the system generations, the duct materials of its streets. Heating and cooling work routed by those codes meets the county in slices, and the slices differ more than the county's shared climate record would suggest.
Neighbouring counties are the honest context for Dallas County's figures. Its 588 square miles sit inside a wider spread of county ground — Guthrie County, Jasper County, Madison County are among the 5 neighbours on its record — and its position northwest of the Des Moines metro's centre places it on its own side of that spread. A system near the county's edge may be closer to a neighbouring county's centre than to its own; the pages are organised by county because the data is, and the links between them carry the rest of the picture.
A service calendar for Dallas County can be written straight from its station record. Spring belongs to the cooling plant: 1,070 cooling degree days are coming, and the systems that will carry them are checked before the first of the 22.0 hot days arrives. Autumn belongs to the heating plant, ahead of 6,178 heating degree days and 127.9 freezing nights. The middle weeks belong to the unglamorous work — filters, drains, duct joints — that both seasons quietly depend on. The record at DES MOINES INTL AP, IA US does not change much year to year, which is what makes the calendar worth keeping.
A short place list shapes Dallas County's service pattern in a specific way. With Waukee the named communities on its record, the county's calls divide between those places and the unincorporated ground around them — and the ground is the larger share of its 588 square miles. Technicians routed here plan for distance as much as for faults: the drive between calls crosses the county's position northwest of the Des Moines metro's centre, and the systems at each end belong to different building decades even when the drive is short.
Ownership writes part of the diary too. Across the Des Moines metro, 69.5% 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. Dallas County shares that metro pattern across its 13 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.
Coverage, for Dallas County, is a set of overlapping maps. The land map is 588 square miles. The address map is 13 ZIP codes and 1 listed communities. The service map is the Des Moines metro, whose coverage the county sits inside — northwest of the Des Moines metro's centre, roughly 15 miles from its centre. The weather map is one station's record, kept at DES MOINES INTL AP, IA US. A home in this county lives on all four maps at once, and its heating and cooling needs are set by the combination.
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 Dallas County and the Des Moines metro.
