Common AC Issues & How We Solve Them
Dealing with an air conditioner that’s not working properly is frustrating, but we aim to make the process simple. Many homeowners aren’t sure what’s causing their AC troubles, but our licensed technicians have seen it all. We diagnose the issue, explain the problem in plain language, and offer a straightforward solution.
In Bellevue, tree pollen and nearby construction sites can clog filters and vents, leading to system failures that often go unnoticed until a breakdown. We address these local challenges by inspecting your equipment thoroughly and finding problems others might miss. We also check for wear and tear common in older Bellevue homes, such as faulty wiring or outdated thermostats that can cause inconsistent cooling. When we visit your home, we work to ensure your air conditioning system not only operates now but can handle future swings in Pacific Northwest weather.
Here’s how we address common AC problems:
- Refrigerant leaks – Low refrigerant levels not only affect cooling, but also lead to costly damage over time. We’ll locate and repair any leaks and recharge your system to the correct level.
- Clogged or dirty filters – Dirty filters reduce airflow and make your system work harder. We’ll clean or replace filters to restore efficiency and performance.
- Compressor failures – A failing compressor often signals serious problems. We’ll assess whether repair or replacement is your best long-term option.
- Electrical malfunctions – Faulty wiring or burned-out components can cause intermittent issues. We handle electrical repairs safely and effectively.
Catching these issues early can extend the life of your system and help you avoid more expensive repairs later. Let us check your system before things escalate.
