Choose a thermostat that works with your specific heating and cooling equipment before comparing apps, appearance, or rebates. Some systems require dedicated controls. A thermostat on a utility’s approved list is not automatically compatible with every HVAC system.
A thermostat upgrade looks like a small purchase, but it is also an equipment-control decision. The control needs to support how your system heats and cools. Before ordering one, identify the existing equipment, current thermostat, and what you want the upgrade to accomplish.
Gather the right information first
- The model of your current thermostat or controller.
- Accessible model information for the indoor and outdoor equipment.
- Whether the home has one system or multiple controlled areas.
- Any equipment manuals or previous installation paperwork.
- The feature you want: remote access, a simpler display, scheduling, or another specific need.
You do not need to remove wiring to start the discussion. A photograph of the existing display and accessible equipment labels can help. Ask the installer what additional information is needed and follow the equipment manufacturer’s control requirements.
Questions to resolve before purchasing
Ask whether the proposed thermostat is supported for the exact equipment models and configuration. Find out whether a dedicated or communicating controller is required to retain the intended operation. Ask how any existing zone controls, supplemental heat, or accessories fit the proposal.
A label such as “smart” describes features; it does not resolve those equipment questions. Get the compatibility answer and included installation work before comparing prices. If the thermostat is part of a new system estimate, have its model included in writing.
Match the features to the way you use the home
| What you notice | What to discuss |
|---|---|
| You want a simpler daily control | Try the display and ask for a demonstration of ordinary temperature and mode changes. |
| You want remote access | Ask about the app, account setup, home internet requirements, and what works if internet is unavailable. |
| You want scheduling | Ask which schedule strategy is appropriate for the equipment and how to adjust it. |
| Several people use the thermostat | Make sure everyone can understand the basic controls and knows where the instructions are kept. |
Before paying for extra features, list the two or three tasks you actually want to make easier. Ask for a setup walkthrough and written instructions. A well-explained control can be more useful than a long feature list that no one in the household uses.
Clark PUD’s thermostat rebate has specific limits
As checked October 11, 2026, Clark Public Utilities lists a $140 incentive for qualifying thermostat upgrades with an electric furnace or ducted heat pump. Its program requires eligible models and a qualifying replacement, excludes dual-fuel homes, and warns that smart thermostats are not recommended for variable-speed heat pumps. The program does not apply to ductless heat pumps or electric baseboard, wall, or cable heat.
Read the utility’s current program rules before buying. Equipment compatibility comes first; program eligibility is a separate check. If you are outside that utility’s service, ask your serving utility about its own rules.
Common thermostat questions
Does Wi-Fi make a thermostat suitable for my heat pump?
No. Remote access is a feature, while suitability depends on the equipment and control requirements.
Should I replace the controller supplied with my new system?
Check with the installer and equipment instructions before changing it. Ask which operating functions the proposed replacement supports.
Can a new thermostat fix every temperature problem?
It does not establish the cause of a comfort problem. If one room stays uncomfortable, see our room-temperature guide and describe the pattern when scheduling.
What should I ask at the end of installation?
Ask for a demonstration of heat/cool selection, normal settings, any schedule, and where to find the model-specific instructions. Confirm whom to contact if an error appears.
