Why Choose Streamline for Thermostat Services

Why isn’t my thermostat turning on the AC or heat?

This can be caused by dead batteries, blown fuses, or loose wiring connections. Our technicians can safely trace the electrical path to identify and fix the interruption.

Should I upgrade to a smart thermostat in Durham?

Smart thermostats are excellent for our variable climate as they adjust settings to save energy when you are away. We can recommend models that integrate best with your existing equipment.

Can you fix a thermostat that reads the wrong temperature?

Yes, this is often a calibration issue or placement problem (e.g., in direct sunlight). We can recalibrate the unit or relocate it for more accurate readings.

Do you work on C-wire installations?

Absolutely, many modern thermostats require a “Common” wire for continuous power. We can install the necessary wiring to ensure your smart thermostat functions reliably.

Count on Streamline for complete temperature control solutions. Our expertise extends beyond simple swaps; we handle the complex electrical integration required for modern systems.

• Diagnostic troubleshooting and sensor testing
• Low-voltage wiring repairs and updates
• Smart thermostat installation and setup
• System programming for energy efficiency

We work with all major brands and models, ensuring your temperature control system matches your comfort needs perfectly.

Watch for these common issues: inaccurate temperature readings, the HVAC system failing to start, the screen going blank, or the system running constantly without reaching the set temperature. These symptoms often indicate a control failure rather than a major system breakdown. Contact Streamline at 919-263-5221 to restore precise control over your home’s climate.
