Frequently Asked Questions
Get answers to common questions about our services
Can I install a thermostat myself?
Simple thermostats with basic wiring are DIY-friendly. However, smart thermostats with C-wire requirements, multi-zone systems, or heat pump compatibility often benefit from professional installation to ensure proper operation.
What's a C-wire and do I need one?
The C-wire (common wire) provides continuous power to smart thermostats. Many older homes lack this wire. We can add one during installation, or install thermostats with C-wire adapters.
Which smart thermostat do you recommend?
We commonly install Ecobee, Nest, and Honeywell smart thermostats. The best choice depends on your HVAC system, smart home preferences, and budget. We'll help you choose during consultation.
