CPS Energy, the municipal utility for San Antonio, runs My Thermostat Rewards: an $85 one-time bill credit for enrolling a smart thermostat in its demand-response program, plus $30 for each year you stay enrolled. It is the furnace-relevant incentive available to San Antonio homeowners, since CPS is an electric utility and Texas has no rebate for repairing a furnace.
The value here is in the thermostat that controls your heating system. A smart thermostat reduces how much your gas furnace runs in winter and your AC in summer, and in exchange for letting CPS make brief temperature adjustments during peak-demand events — which you can override — you collect the enrollment and annual credits. For a household that has just spent money on a furnace repair, it is an easy way to claw some of that back and lower the next heating bill.
Two details matter. First, you must own a qualifying smart thermostat; a unit CPS installed for free under a different program does not earn the rewards credit. Second, watch the amount: CPS ran a richer $150 promotional credit that ended for enrollments before January 1, 2026, so the current standing figure is $85 — don't count on the old promo.
The enrollment itself is simple: own a supported Wi-Fi thermostat — the common ecobee, Google Nest, and Honeywell Home models are generally eligible — connect it to your account, and opt in. During a demand event CPS nudges your setpoint a few degrees for a short window; you keep full manual control and can override any event from the thermostat or app, and the heating-season benefit comes from the everyday scheduling, not the events.
CPS Energy also offers a free A/C tune-up and separate HVAC and heat-pump equipment rebates through its STEP program; if you are facing a furnace replacement rather than a thermostat upgrade, ask CPS which equipment incentives currently apply. Confirm all amounts on the CPS Energy site before enrolling.
