Johnson's Heating & Refrigeration | Emergency HVAC Repair in Vancouver, WA

Short-cycling, where your system turns on and off frequently, is often caused by an oversized unit, a faulty thermostat, or a refrigerant issue. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause, whether it's recalibrating your thermostat, repairing refrigerant lines, or assessing if your system is properly sized for your Vancouver home, ensuring it runs efficiently.

Common signs include uneven temperatures between rooms, higher-than-usual energy bills, and excessive dust. We conduct a professional duct inspection using specialized tools to locate leaks. We then seal these leaks with durable mastic or metal-backed tape, which improves airflow, enhances comfort in every room, and can significantly reduce your monthly heating and cooling costs.

We recommend bi-annual maintenance, typically in spring and fall. Our preventative service includes cleaning coils, checking refrigerant levels, inspecting electrical components, and testing system controls. This proactive care helps prevent duct deterioration, ensures proper cycling, and extends the life of your system, saving you from costly emergency repairs during our peak seasons.
