Each year as summer turns into autumn, The Darville Company offers the Fall Clean & Test. The changing seasons are a perfect time to get your system checked out – when you’re switching over from heating to air conditioning or vice versa. Now, we’re taking the Fall Clean & Test to a whole new level with the Peak Performance Agreement. In this post, we’ll explain the Clean & Test as well as what’s included for Peak Performance!


The Fall Clean & Test focuses on your gas or electric heating system. Many of these tasks should definitely be performed by a licensed professional. The Clean & Test includes the following services:

  • Check, clean and/or replace all filters (a complementary 1” pleated filter in standard sizes is provided)
  • Check and thoroughly clean the blower wheel, including the housing
  • Check all electrical connections
  • Check and clean the combustion air chamber
  • Check the heat exchanger
  • Clean the pilot assembly
  • Check the condensate drain on condensing furnaces, clear and clean if needed
    • A clogged drain pipe can cause significant water damage to your home if left unchecked.
  • Check and lubricate motors
  • Check all safety controls 
    • This is especially important as we switch from air conditioner to heat!
  • Check the power supply to the system
  • Check and calibrate the thermostat
  • Check the outdoor fan motor for heat pumps units
    • Fan maintenance is critical to avoid spending hundreds of dollars for a replacement.
  • Check the belts and adjust or replace if necessary
  • Clean and adjust burners
  • Check heat and fan relays and capacitors
  • Check temperature differential
    • This ensures your system is operating properly.
  • Provide maintenance supplies


The Peak Performance agreement is another layer of security offered to our customers. This includes a premium service on all the points listed above. Some of the upgraded aspects include:

  • Fully level and calibrate thermostat
  • Completely remove wash blower if needed
  • Chemically clean condenser coil if needed

  • Inspect and lubricate every moving part
  • Tape any leaking joins around the plenum coil

In addition, the Peak Performance agreement also includes services for after-hour emergencies at no extra charge, and offers contracts for routine maintenance schedules. You’ll also have one technician dedicated to your account, who you’ll get to know and trust.
