Answers to Common Questions
View All FAQsWhy Is My Smart Thermostat Not Connecting to Wi-Fi?
Most smart thermostats fail to connect because they use 2.4 GHz, your router is on 5 GHz, the signal is weak, or the password is wrong. Router settings like MAC filtering, hidden SSID, or disabled DHCP can also block pairing.
Quick checks:
- Reboot the thermostat and router.
- Join the 2.4 GHz SSID and move closer.
- Re-enter the Wi‑Fi password.
- Disable MAC filtering/AP isolation; enable DHCP.
- Update router and thermostat firmware, then retry setup.
We also test controls and remote operation during tune-ups.

Professional thermostat rewiring is priced after an on-site inspection. Final cost depends on thermostat type (programmable or smart), the condition of existing wires, access to the furnace/air handler, and whether a new C-wire or cable run is needed. We provide thermostat inspection, repair, and replacement, then test controls, thermostats, and remote operation for ease of use. We also set up the thermostat and show you how to use it. Service available in Noblesville, Carmel, Fishers, and Westfield.

Professional thermostat replacement cost varies by thermostat type, features, wiring, and system integration. Exact pricing depends on inspection, and a technician will confirm costs on site. We install, replace, program, and test thermostats, and we can show you how to use your smart controls. Pricing upfront—you agree to the price before the work starts. Service available in Carmel, Noblesville, Fishers, and Westfield.
Quick checks before you replace:
- Replace batteries
- Check breaker/fuse
- Verify mode and temperature settings
- For smart units, confirm Wi‑Fi

Many homeowners can replace a like-for-like thermostat, but smart, multi-stage, or heat-pump controls are best handled by a pro. We install, repair, and upgrade thermostats and smart controls, then set up and program them to work with your HVAC. During tune-ups we test controls and remote operation. In Noblesville, Carmel, and Fishers, correct wiring and compatibility prevent nuisance shutdowns. After installs, our techs show you how to use your smart thermostat.

Most homeowners can handle simple thermostat fixes. Replace batteries, verify mode/settings, and restart the unit. If the display is dead, wiring is loose, the system short cycles, or you’re adding a smart thermostat, hire a professional. Summers Plumbing Heating & Cooling installs, repairs, and programs thermostats, and we test controls during tune-ups. Our Noblesville team also upgrades to energy‑saving and programmable models and shows you how to use them. Consider a maintenance plan for priority service and discounts.
