Denver's dry climate makes swamp coolers (evaporative coolers) an energy-efficient option for many homes. They work best when humidity is low, typically using 75% less electricity than central AC. However, central air conditioning provides more consistent cooling and better humidity control, especially during our occasional humid spells.

Our recommendation: Swamp coolers are excellent for dry summer days and can be very cost-effective. Central AC offers superior comfort and reliability. We can assess your home's layout, insulation, and your comfort preferences to recommend the best system for your Denver home.

Most HVAC systems last 10-15 years in Denver's climate. Consider replacement if your system is over 10 years old and requires frequent repairs, if your energy bills are rising significantly, or if it struggles to maintain comfortable temperatures during extreme weather.

Other signs include uneven heating/cooling, excessive noise, or if your system uses R-22 refrigerant (which is being phased out). Modern systems are 20-40% more efficient, which can lead to substantial savings on Denver's utility bills.

Denver's dramatic temperature swings require specific maintenance:

• Spring: Schedule AC tune-up before summer heat arrives. Clean or replace filters, clear debris around outdoor units.
• Fall: Get furnace inspected before first freeze. Check thermostat settings, clean vents, and ensure proper airflow.
• Year-round: Change filters every 1-3 months, keep outdoor units clear of snow and debris, and monitor for unusual noises or smells.

Preventive maintenance can prevent 85% of emergency breakdowns and extend your system's life by years.

While exact costs depend on your specific system and the repair needed, here are typical ranges for Denver-area HVAC repairs:

• Thermostat replacement: $150 - $400
• Capacitor replacement: $200 - $450
• Refrigerant recharge: $200 - $600 (plus leak detection if needed)
• Blower motor replacement: $450 - $800
• Compressor replacement: $1,200 - $2,500
