Heating & Cooling Basics
How the furnace, air conditioner, and boiler in your Iowa home actually work — the plain-language layer under every quote.
How a Gas Furnace Works (and Why It Stops)
A gas furnace heats your home in a fixed sequence: thermostat call, ignition, burners, heat exchanger, then blower. When a furnace fails, it almost always fails at one specific step in that chain — which is how technicians diagnose it.
Read the guide Learn · Air ConditioningHow Central Air Conditioning Actually Works
Central air conditioning doesn't create cold air — it moves heat from inside your home to the outdoors using refrigerant, a compressor, and two coils. Understanding those parts explains most AC problems Des Moines homeowners see.
Read the guide Learn · BoilersHow Boiler Heat Works — Radiators, Radiant Floors, and Hydronics
A boiler heats water and circulates it through radiators, baseboards, or floor tubing — no ducts, no blowing air. Many older Des Moines neighborhoods still run on boiler heat, and a well-kept boiler is among the longest-lived heating systems made.

In central Iowa, a cold-climate heat pump heats cheaper than gas for most of the season, and a gas furnace wins during deep cold. That's why the strongest answer for many Des Moines homes is both — a dual-fuel system.
Read the guide Learn · Indoor Air QualityWhy Is My House So Humid in Summer? (An Iowa Problem)
Indoor humidity should sit between 30 and 50 percent. Iowa summers push outdoor humidity to 70–82 percent, and if your home feels sticky at 74°F, the usual culprits are an oversized AC, air leakage, or a damp basement — not the thermostat setting.
Read the guide Compare · Ductless Mini-SplitsWhy Your Upstairs Is Hot Every Summer — and What Actually Fixes It
Upstairs rooms run hot because heat rises, attic temperatures soar, and most single-system homes were ducted for one thermostat downstairs. Fixes range from free airflow adjustments to zoning to a dedicated ductless head — in that order.
