Why Is My Sacramento House Making That Noise?

October in Sacramento brings warm afternoons and cool nights, and homes respond with new sounds. Most have ordinary explanations.

Before tracking one down, note when it happens, where it seems to come from, and what else was going on.

Why Homes Pop in the Evening

Big swings between afternoon and evening temperatures make roof framing and attic ductwork expand and contract, producing pops and ticks after sunset. New cracks, sticking doors, or soft floors are worth a professional look.

Plumbing Noises

A bang after the washer shuts off is often water hammer. Water heaters can rumble with sediment buildup. Running water when nothing is on deserves a meter check.

Heating and A/C Sounds

Furnaces and heat pumps click, hum, and whoosh. Heat pumps hiss in defrost mode on foggy winter mornings. Whole-house fans thump as they start. New grinding, squealing, or banging is worth a call. If you smell gas, leave and call PG&E or 911 from outside.

Wind Rattles

North winds can whistle through gaps around windows and doors and rattle vents, gutters, and branches.

Roof Rats and Other Visitors

Roof rats are common in Sacramento and active at night, often using fruit trees and fences to reach the roof. A licensed pest control company can help.

What to Tell the Professional

Describe the sound, where and when you hear it, and what else is running. "The attic ducts pop every night around 8 when the house cools" gives a technician a clear picture.
