Common AC Issues and How We Solve Them
Dealing with an air conditioner that’s not working properly can be stressful, but we’re here 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’ll diagnose the issue, explain the problem in plain terms, and offer a clear path to a solution.
Here’s how we address common AC problems:
- Refrigerant leaks – Low refrigerant levels don’t just affect your cooling but can also lead to costly damage over time. We’ll locate and fix any leaks while recharging your system to the optimal 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 issues. We’ll assess whether repair or replacement is the best long-term option for your system.
- Electrical malfunctions – Faulty wiring or burned-out components can cause intermittent issues. We’re equipped to handle electrical repairs safely and effectively.
Catching these issues early can extend the life of your system and help you avoid more costly repairs down the road. Let us check it out before things escalate.
