Questions and Answers
What are the signs my condenser coils are dirty and need cleaning?
Common signs include your AC unit running longer to cool your home, reduced airflow from vents, higher than usual energy bills, and the system frequently cycling on and off. Dirty coils in our Springfield climate force your system to work much harder. We recommend professional cleaning to restore efficiency and prevent strain on the compressor.
Why is my heat pump blowing cool air when set to heat?
This is often a symptom of a faulty reversing valve, a common issue we see in Springfield. This valve switches the system between heating and cooling modes. When it's stuck or failing, your heat pump can't properly reverse the refrigerant flow. Our technicians can diagnose and repair or replace the valve to restore proper heating function.
How can regular maintenance prevent these common HVAC problems in Springfield?
Our local, seasonal maintenance includes cleaning condenser coils, checking refrigerant levels, and testing all electrical and mechanical components, including the heat pump's reversing valve. This proactive care catches small issues before they lead to breakdowns, improves energy efficiency for Missouri's hot summers and cold winters, and extends the overall lifespan of your system.
