Frequently Asked Questions
How well do the new AC units handle our 90-degree summer days?
Denver's design temperature is 91°F, but temperatures can exceed 100°F. Modern systems using R-454B refrigerant are engineered for these highs, maintaining a stable 15-20°F delta T (temperature drop) across the evaporator coil. This refrigerant's lower global warming potential doesn't compromise its ability to reject heat efficiently at peak loads, unlike older R-22 systems that would struggle and lose capacity.
Should I switch my gas furnace to a heat pump with Denver's cold winters?
Modern cold-climate heat pumps operate effectively down to -5°F, covering most Denver winter lows. The key is managing Xcel Energy's peak hours from 1-7 PM, when electric rates are highest. A hybrid system, pairing a heat pump with your existing gas furnace as a backup during peak times and extreme cold, optimizes cost. The $8,000 federal rebate makes this dual-fuel transition financially viable.
Can my older home's ducts handle a better air filter for wildfire smoke and pollen?
Galvanized steel ductwork, common in Denver homes, is structurally sound but often undersized for modern airflow needs. Installing a MERV-13 filter for PM2.5 and May pollen peaks increases static pressure. A technician must measure your system's external static pressure; exceeding 0.5 inches of water column can starve the blower, reduce cooling capacity, and cause evaporator coil freezing.
What if my AC stops working during a Uptown heatwave?
A no-cool emergency requires a technician to check refrigerant charge and electrical components. Our service vans stationed near City Park can access Uptown via I-25 within the 15-25 minute window. This rapid dispatch is critical to prevent secondary compressor damage from running a low-charge system, which is a common failure mode in our climate.
My air conditioner is from the 80s. Is that why it ices up in Denver?
A system from Denver's 1981 construction era is now 45 years old, exceeding its typical design life by two decades. Aged evaporator coils develop micro-leaks that lower refrigerant charge. This low charge, combined with our high diurnal temperature swings—where a 90°F day can drop to 60°F at night—causes the coil temperature to plunge below freezing. The resulting condensation freezes into a block of ice that halts airflow and cooling.
Is the new 14.3 SEER2 standard worth the investment with current electric rates?
The 14.3 SEER2 minimum for 2026 represents a 10-15% efficiency gain over previous models. At Denver's 14 cents per kWh rate, upgrading a 3-ton system from a 10 SEER unit can save about $450 annually on cooling. The active Inflation Reduction Act rebates, capped at $8,000 for qualified heat pumps, can effectively offset 50-100% of the premium for a high-efficiency system, making the payback period significantly shorter.
My Nest thermostat shows an E195 alert. What does that mean for my system?
The Nest E195 code signals a loss of communication with your HVAC system's safety circuit. In Denver, this often points to a tripped high-pressure switch from an overcharged system or a clogged condenser coil near City Park, where cottonwood and pollen accumulation is heavy. It's a protective shutdown to prevent compressor damage and requires a technician to diagnose the refrigerant charge and coil cleanliness.
What permits and safety rules apply to a new AC installation in Denver?
All HVAC replacements require a permit from Denver Community Planning and Development. For 2026, installations using A2L refrigerants like R-454B—which are mildly flammable—must follow strict new codes. These mandate leak detectors, updated electrical classifications, and specific airflow markings. Your contractor must file the permit and schedule an inspection to ensure the system meets these updated safety standards for your home.
