Common questions about ClimateMaster
What is the difference between ClimateMaster Tranquility and Trilogy?
Tranquility is ClimateMaster's standard two-stage series — solid, reliable, and more affordable. Trilogy is their variable-speed premium line. The Trilogy 45 Q-Mode can redirect excess heat to your water heater, cutting water heating costs by up to 70%. If you're building new or doing a full retrofit, Trilogy is worth the extra cost.
How much does a ClimateMaster system cost?
Installed costs for a ClimateMaster system typically run $22,000 to $45,000 for a residential home, depending on size and loop type. Tranquility systems are at the lower end, Trilogy at the higher end. The 30% federal tax credit brings the effective out-of-pocket cost down significantly.
Is ClimateMaster a good brand?
Yes. ClimateMaster has been making geothermal systems for over 60 years and is the most widely installed brand in the US. Their systems are well-regarded by contractors and have a strong service network. The Trilogy 45 regularly appears on contractor recommended lists.
What is the COP of a ClimateMaster Trilogy 45?
The Trilogy 45 has a rated COP of up to 5.0 in heating mode, meaning it delivers 5 units of heat for every 1 unit of electricity consumed. In cooling mode (EER), it rates up to 41.5. These are among the best efficiency numbers for any residential HVAC system.
