That sudden loud humming noise from your outdoor AC unit isn’t just annoying—it’s a warning sign. When your AC fan motor struggles under layers of dust and lawn debris, it can overheat and shut down just before the hottest weekend of the year. Here at Robben & Sons, we know how stressful a failing cooling

A small water stain on your ceiling might seem harmless at first, but it can quickly turn into a costly mess. When your air conditioner pulls heavy moisture in July, a clogged condensate drain line can cause hidden water leaks that spread unnoticed. The team at Robben & Sons has seen how devastating these hidden

That musty, locker room smell hitting the moment your AC turns on isn’t just in your head. In Oregon’s damp spring air, bacteria and mold take hold on the evaporator coil, causing the dreaded “Dirty Sock Syndrome.” At Robben & Sons, we’ve seen how quickly the Pacific Northwest moisture can turn a cooling system into

That sharp, high-pitched chirp your blower motor makes when the fan starts is more than just an annoyance. After a long heating season, dry or worn motor bearings often cause that noise, signaling trouble ahead.

These cracks can leak carbon monoxide, turning a simple furnace issue into a serious safety risk.

A mystery puddle or a sudden ceiling leak is often the result of a clogged HVAC condensate line, a common issue during the damp months of April. The consistent 50°F to 60°F weather in the Pacific Northwest turns these lines into a breeding ground for algae and slime that has remained stagnant all winter. When

Oregon winters don’t follow a script—one day it’s 35°F, the next it’s 55°F. That means your electric bill from running a heat pump can spike during cold snaps, while gas bills climb on milder days. The dual fuel strategy with hybrid heating systems solves this by switching between a gas furnace and an electric heat
