Terry's Heating & Cooling: Emergency HVAC Repair Serving Rolla, MO 65401

Yes, that's a classic sign of a reversing valve issue, which we see frequently in Rolla due to our system usage patterns. We'll first perform a thorough diagnostic to confirm the valve is the culprit, checking pressure, electrical signals, and for any mechanical sticking. If repair isn't viable, we'll recommend a precise replacement with a high-quality valve suited for our local climate, ensuring your heat pump operates efficiently again.

Thermostat problems are common and can lead to discomfort and high energy bills. We start by checking the wiring, power source, and calibration. Often, a simple recalibration or wiring repair solves it. If the unit is outdated or faulty, we'll explain your options for a reliable replacement, including modern programmable or smart thermostats that can better handle Rolla's temperature swings and improve your home's efficiency.

We recommend bi-annual maintenance—once in spring for your cooling system and once in fall for heating. Our local-focused tune-up includes cleaning the reversing valve mechanism to prevent sticking, testing thermostat accuracy and connections, checking refrigerant levels, and inspecting electrical components. This proactive care helps catch small problems before they become major repairs, extending your system's life and maintaining its efficiency through our Missouri seasons.
