What Does Professional AC Service Include?

We follow a rigorous multi-point checklist that addresses every critical component of your cooling system. Unlike “splash and dash” services, our air conditioning service includes:

  • System Diagnostics: We measure voltage and amperage on motors to ensure they are operating within manufacturer specifications.
  • Deep Coil Cleaning: We remove the “cottonwood fuzz” and Colorado dust from your outdoor condenser coils, which is the #1 cause of efficiency loss.
  • Refrigerant Pressure Check: We verify that your system has the exact charge required for optimal heat transfer.
  • Electrical Safety Inspection: We tighten all connections and inspect contactors and capacitors for signs of wear or pitting.
  • Condensate Line Clearing: We flush the drain lines to prevent clogs that can lead to water damage in your home.
  • Thermostat Calibration: We ensure your control system is accurately reading your home’s temperature.

The Benefits of Professional HVAC Service

Investing in annual AC service isn’t just about comfort—it’s about smart homeownership:

  • Lower Monthly Bills: A well-serviced unit can run up to 15% more efficiently, directly lowering your Xcel Energy or CORE utility costs.
  • Extended Equipment Life: Regular cleaning and lubrication reduce the friction and heat that cause compressors to fail prematurely.
  • Warranty Compliance: Most major brands like Carrier and Champion require annual service records to honor parts warranties.
  • Air Quality Improvement: By cleaning the internal components and checking your filters, we help reduce the circulation of allergens and dust.
