Highlands Ranch homeowners face unique HVAC challenges due to our elevation, climate conditions, and the area’s mix of home ages and construction styles. Understanding common problems and knowing when to attempt DIY solutions versus calling professionals can save both money and prevent system damage.
Climate-Specific HVAC Challenges in Highlands Ranch
High Altitude Effects
At approximately 5,500 feet elevation, Highlands Ranch HVAC systems operate under different conditions than sea-level equipment:
- Reduced air density affects heat transfer efficiency
- Lower atmospheric pressure impacts refrigerant systems
- Increased UV exposure degrades outdoor components faster
- Greater temperature swings stress system components
Seasonal Stress Factors
Winter Challenges:
- Extreme temperature variations (from -10°F to 60°F+)
- Dry air conditions affecting humidity control
- Snow and ice accumulation on outdoor units
- Increased heating demands during cold snaps
Summer Demands:
- Intense afternoon sun on south/west-facing equipment
- Rapid temperature changes during thunderstorms
- Dust and pollen loading air filters quickly
- Wildfire smoke affecting air quality systems
Most Common HVAC Problems in Highlands Ranch
1. Uneven Heating and Cooling
Symptoms:
- Some rooms consistently too hot or cold
- Temperature differences of 5°F+ between floors
- Frequent thermostat adjustments needed
- System runs constantly but doesn’t reach set temperature
Common Causes:
- Ductwork leaks or poor insulation
- Blocked or closed vents
- Dirty air filters restricting airflow
- Incorrectly sized equipment for home layout
DIY Troubleshooting:
- Check and replace air filters
- Ensure all vents are open and unobstructed
- Verify thermostat settings and programming
- Examine ductwork in accessible areas for obvious damage
When to Call Professionals: If problems persist after basic troubleshooting, professional assessment may reveal:
- Ductwork design issues requiring modification
- Equipment sizing problems needing system replacement
- Hidden duct leaks requiring specialized detection
- Zoning system needs for better comfort control
2. Frequent System Cycling
Symptoms:
- System turns on and off every few minutes
- Never reaches comfortable temperatures
- High energy bills despite minimal runtime
- Increased wear on system components
Potential Causes:
- Oversized equipment (common in Highlands Ranch’s larger homes)
- Dirty air filters or coils
- Refrigerant leaks affecting cooling efficiency
- Faulty thermostat or control systems
DIY Steps:
- Replace air filters with appropriate MERV rating

- System shutdowns due to pressure switches
- Heat pump defrost cycles not functioning
Summer Ice Issues:
- Indoor coil freezing due to airflow restrictions
- Refrigerant leaks causing ice formation
- Dirty filters reducing airflow
Immediate Actions:
- Turn off system to allow ice to melt naturally
- Check and replace dirty air filters
- Ensure outdoor unit drainage is clear
- Never attempt to chip or melt ice manually
Professional Intervention Required:
- Refrigerant system diagnosis and repair
- Defrost system troubleshooting and replacement
- Airflow testing and ductwork evaluation
