Q&A

Why does my heat pump seem to blow cool air when set to heat, and can you fix it?

This is a classic sign of a heat pump reversing valve issue, a common problem we see in Fort Smith. The valve is responsible for switching the system between heating and cooling modes. When it gets stuck or fails, your heat pump can't properly heat your home. Our technicians are experts at diagnosing and repairing or replacing faulty reversing valves to restore efficient heating to your Fort Smith home.

My thermostat in Fort Smith is unresponsive or showing incorrect temperatures. What should I do?

Thermostat malfunctions are a frequent cause of HVAC discomfort in our area. First, check the batteries if it's a wireless model. If that doesn't help, the issue could be with the wiring, a calibration error, or the unit itself. Our team can quickly diagnose whether your thermostat needs recalibration, wiring repair, or a replacement with a modern, more reliable model suited for Fort Smith's climate.

What's included in a diagnostic visit for my malfunctioning HVAC system?

When you call us for a diagnostic visit, our expert technician will perform a thorough inspection of your entire system. We'll test the thermostat operation, check electrical components, assess refrigerant levels, and inspect key parts like the heat pump's reversing valve and compressor. You'll receive a clear, honest explanation of the problem, a detailed repair estimate, and options to fix it, ensuring you understand exactly what's needed to solve your Fort Smith home's HVAC issue.
