Furnace Replacement and Duct Redesign in Sunset, Utah

Sunset's 1950s HAFB-era homes often have original cast-iron gravity furnaces that have been converted twice — every install here needs a full duct redesign, not just equipment swap.

• 1950s Sunset homes often began with cast-iron gravity furnaces converted to forced air; the leftover ductwork is why every install here gets a full duct redesign.
• Heating and cooling is most of our Sunset work, and our recent heating and cooling calls have been full system installs and estimate visits; we size the new system from a load calculation, not the old nameplate.
• Duct redesign is what makes the back bedrooms in a mid-century Sunset home finally reach the thermostat setting.

Sunset water is hard (~16 gpg) on a municipal supply. Unsoftened hard water cuts water-heater life 20–30% by scale, slows tankless flow rates, and leaves film on glass and fixtures. A properly sized ion-exchange softener plus under-sink reverse osmosis at the kitchen sink is our baseline plumbing package here, and we match softener capacity to measured grains-of-hardness plus gallons-per-person-per-day — not a one-size spec sheet.

• Pipe leaks in post-war supply lines come up here; supply plumbing from the 1950s has done its time.
• Hard Davis County water at about 16 grains scales water heaters; flushing and softening extend their life.
• We handle water heater replacement, leak repair and drain cleaning in Sunset on the same schedule as HVAC.

Most pre-1970 homes here still have 60–100A service, cloth-insulated conductors, and pushmatic or FPE Stab-Lok panels. Panel replacements and partial rewires are the bread and butter.

• Post-war panels and wiring were not built for modern appliance loads; electrical safety upgrades are common in Sunset.
• A load calculation and often a service upgrade come before adding central air or an EV charger to a 1950s home.
• Grounding, outlet replacement and whole-home surge protection round out the electrical work we do in mid-century Sunset homes.
