Answers to Common Questions
View All FAQsWhy Is My Smart Thermostat Not Connecting to Wi-Fi?
Most smart thermostats fail to join Wi‑Fi due to weak signal at the wall, wrong network/password, 5 GHz–only routers (many thermostats need 2.4 GHz), router security/settings conflicts, or low thermostat power. Our trained techs install and integrate smart thermostats and can diagnose connection issues in Roanoke, Cave Spring, and nearby areas.
Quick checks:
- Confirm 2.4 GHz SSID and correct password.
- Reboot router and thermostat.
- Move router or add a Wi‑Fi extender.
- Disable VPN/guest isolation; update router firmware.
- Verify C‑wire/power at the thermostat.

Yes, you can replace a thermostat yourself, but professional installation helps ensure compatibility and proper setup. We install thermostats and smart controls, integrate with smart-home systems, and adjust system controls for efficient operation. Some thermostats won’t work with certain systems; our techs verify fit and explain options on site. Tune-ups and Diamond Club visits include control checks that support reliable performance in Roanoke and Rocky Mount.

Yes, you can handle simple thermostat checks yourself, but hire a professional for wiring, replacements, or smart-home integration. DIY fixes cover settings and power; pros handle compatibility, control wiring, and system diagnostics.
Quick checks:
- Replace batteries or verify power to the thermostat.
- Confirm mode, temperature, and schedule settings.
- Check breaker and furnace/air handler switch is on.
- For smart models, reconnect Wi‑Fi and app.
- If the display is dead or the system short-cycles, call a technician.
Wisler offers $99 tune-ups and Diamond Club membership for prioritized HVAC service.
