Question Answers
Why is my upstairs so much hotter than my downstairs in my St. Louis home?
Uneven cooling is a frequent issue here, often caused by an unbalanced duct system, an undersized AC unit, or poor attic insulation. Our technicians perform a detailed airflow analysis and static pressure test to pinpoint the cause. We then correct it with duct adjustments, zoning solutions, or system recommendations to balance your home's temperature from the basement to the attic.
My heat pump is stuck in cooling mode and won't switch to heat. What's wrong?
This is a classic sign of a failing reversing valve, a common problem for St. Louis heat pumps due to year-round use. This valve directs refrigerant flow to change between heating and cooling. We'll test the valve's solenoid and electrical controls. Often, it can be repaired, but if the valve itself is stuck, we'll replace it to restore your system's proper function for our unpredictable Midwest seasons.
What regular maintenance can prevent these common HVAC issues in my home?
Preventative maintenance is key. Our twice-a-year tune-up includes checking refrigerant charge (a major cause of uneven cooling), testing the heat pump's reversing valve operation, cleaning coils, and ensuring all electrical components are secure. This proactive service catches small problems before they leave you uncomfortable during a St. Louis heatwave or cold snap, saving you money on major repairs.
