Q&A
My heat pump isn't heating properly. Could it be the reversing valve?
In Lenoir's climate, a failing reversing valve is a common culprit when a heat pump struggles to switch between heating and cooling modes. This critical component directs refrigerant flow. Symptoms include the system blowing cool air when set to heat, or getting stuck in one mode. Our technicians can diagnose valve issues quickly and recommend the most cost-effective repair to restore your system's full functionality.
Why is my AC running but not cooling my house on a hot Lenoir day?
When your air conditioner runs but doesn't cool, it's often due to issues like low refrigerant, a dirty or frozen evaporator coil, or a failing compressor—all problems exacerbated by our sustained summer heat. This puts extra strain on the system. We'll perform a comprehensive check, including airflow and pressure tests, to pinpoint the exact cause and get your home cool and comfortable again.
What's the most important maintenance for my HVAC system before summer hits Lenoir?
Before our hot, humid summers arrive, the most crucial step is a professional tune-up. We'll clean the condenser and evaporator coils, check refrigerant levels, ensure electrical components are tight, and verify the system is operating at peak efficiency. This proactive service can prevent common breakdowns, improve cooling performance, and lower energy bills during the season when you need your AC the most.
