High Altitude Heating and Air: Emergency HVAC Services Serving Denver 80260

In Denver's dry climate, frozen coils are often caused by restricted airflow from a clogged air filter or low refrigerant levels. Both issues force the coil to work harder and drop below freezing, forming ice. Our technicians diagnose the root cause—whether it's a simple filter change, a refrigerant leak repair, or a blower motor issue—to prevent recurring breakdowns and protect your system.

Absolutely. A failing pilot light is a common issue in Denver, often due to a dirty or faulty thermocouple, a draft blowing it out, or a clogged pilot orifice. Our experts will safely inspect, clean, and adjust the pilot assembly or replace worn components to ensure your furnace ignites reliably, keeping your home warm during our unpredictable winters.

Given our altitude and temperature swings, biannual maintenance is key. Before winter, we focus on the heating system: checking the heat exchanger, cleaning burners, and testing the thermocouple. Before summer, we prioritize cooling: cleaning condenser coils, checking refrigerant, and ensuring proper airflow to prevent coils from freezing. This proactive care prevents common local failures and extends your system's life.
