Frequently Asked Questions
My heat pump isn't switching between heating and cooling correctly. What's wrong?
This is a common issue in Centennial, often caused by a faulty reversing valve—the component that changes the flow of refrigerant for heating or cooling mode. When it sticks or fails, your system can't properly adjust to our changing weather. Our technicians are experts at diagnosing and repairing reversing valve issues to restore your heat pump's full functionality efficiently.
How can I tell if my furnace is at risk for a carbon monoxide leak?
Warning signs include a yellow or flickering burner flame (it should be steady and blue), soot around the furnace, excessive moisture on windows, or a strange, pungent odor. The safest approach is an annual professional inspection and tune-up. We thoroughly check heat exchangers for cracks, test for CO leaks, and ensure proper ventilation—critical steps for every Centennial home's safety.
What's included in a standard HVAC safety and performance check?
Our comprehensive check-up includes testing for carbon monoxide, inspecting the heat exchanger for cracks, cleaning essential components, checking refrigerant levels, calibrating the thermostat, and ensuring all electrical connections are secure. This service is designed to catch problems like failing valves or safety hazards early, improving efficiency and giving you peace of mind for the season ahead.
