What It Costs
What's Included in Every Installation
Air-cooled or liquid-cooled?
The Cummins air-cooled range covers most DFW homes: 13kW to 20kW, natural gas or LP, published at 65 dB(A) at 23 feet, and carrying a 5 year / 2,000 hour limited warranty. Above that the liquid-cooled RS range starts at 25kW for larger homes and multi-zone HVAC, and carries a 2 year standby base warranty rather than five — a real difference worth knowing before comparing two quotes. The automatic transfer switch is a separate product with its own 2 year warranty. Sizing is decided by air conditioning load, not square footage, so the recommendation comes from a load calculation rather than a quota.
