Furnace repair calls in Golden Valley homes
Most Golden Valley homes date from the 1940s through the 60s, so the furnace in a typical rambler or split-level is two or three generations removed from the original, working through ductwork laid out 70-odd years ago. The everyday repairs are familiar: a flame sensor that needs cleaning, an igniter at the end of its life, an inducer that growls on startup, a pressure switch that won't close because its hose has cracked.
What stands out here is the ductwork around the furnace. Many ramblers have been added onto, and the addition sits at the far end of a long trunk with a small supply and no return, so it runs cold while the rest of the house is warm and the furnace itself tests fine. Split-levels spread heat across several short floors from one trunk, and dampers set years ago often need resetting after a furnace change. Temperature rise and airflow are worth measuring before a part is blamed, so a duct problem isn't mistaken for a failed one.

Furnace repair in Golden Valley: questions
Our Golden Valley house has heat ducts in the slab and smells musty when the furnace runs. Why?
Perimeter ducts buried in a slab, found in some mid-century houses, can rust, crack or take on groundwater over the decades, and the furnace then blows air across that damp duct. A musty smell, rust flakes at the floor registers or weak airflow in some rooms are the signs. We look into the ducts with a light or camera where we can reach, and if they're failing, we lay out the options before you spend money on the furnace.
Can leaves or nests block the furnace vent on our wooded Golden Valley lot?
Yes. The PVC intake and exhaust on a high-efficiency furnace are open pipes near the ground, and leaves, wasp nests and bird nests can partly block them, especially the intake. Snow sliding off a roof onto the terminations does the same in winter. The pressure switch then shuts the furnace down. Check that both pipes are clear before you call; a screen, where the manufacturer allows one, or a better termination can prevent a repeat.
