Neat, level, and built to last, that's how outdoor equipment should sit against a home. 🔧

This setup shows a pair of Lennox outdoor units resting on solid concrete pads over clean gravel, with the electrical panels mounted tight along the wall. That kind of placement isn't just about looks. Proper elevation keeps equipment out of standing water, good clearance helps airflow, and tidy wiring makes future ac repair and air conditioner service faster and safer. As we head deeper into the damp, chilly stretch around Seattle, it's also a good reminder to clear leaves and debris away from your outdoor unit so it can breathe.

Signs your outdoor setup may need attention:

• The unit tilts or the pad has settled
• Vegetation or debris crowds the sides
• Unusual rattling or buzzing during startup

Whether you need hvac repair, heat pump repair, or a properly planned hvac installation with load calculations and permits handled for you, our factory-trained technicians have been doing it right since 1938. And if your system is aging, we can walk you through heat pump installation options that may qualify for Puget Sound Energy rebates and federal tax credits.

That dusty, burning smell when you first turn on the furnace for the season can be alarming. For most homes in the Seattle area, it's a normal and temporary result of dust burning off internal parts that have been dormant all summer.

However, some odors can signal a real problem with your heating system. Knowing how to tell the difference is key to your peace of mind and safety. Our new article explains what causes the common burning dust smell and what warning signs to look for that might indicate you need a professional furnace inspection.

Read our guide to learn when that smell is harmless and when it's time to have your system checked.

Is your heat pump or furnace acting like it has a mind of its own, turning on and off randomly? These frustrating "ghost" symptoms often point to a specific electrical part failing inside your unit, not a problem with your thermostat.

Before a minor issue leads to a complete breakdown during a cold Seattle night, it's important to understand the cause. A failing contactor, a small but critical high-voltage switch, is frequently the culprit behind these intermittent power drops. Our new article explains what a contactor does, how to recognize the warning signs, and why addressing it now can save you from an emergency heating repair call later.

Find out more about this common heating problem by reading our latest post.
