Q&A
My AC in Knoxville turns on and off constantly. What's causing this short cycling, and how can you fix it?
Short cycling is common here, often caused by an oversized unit, a dirty air filter restricting airflow, or a failing capacitor. Our technicians will perform a comprehensive diagnosis to pinpoint the exact cause—whether it's a simple cleaning, a refrigerant charge adjustment, or a component replacement—to restore proper, efficient operation and prevent undue wear on your system.
Why is my thermostat in Knoxville not reading the temperature correctly or causing my HVAC to behave erratically?
Thermostat malfunctions can stem from aging units, incorrect calibration, dust buildup, or wiring issues. We troubleshoot by checking the location (away from direct sunlight or drafts), verifying calibration, inspecting connections, and ensuring compatibility with your HVAC system. Often, an upgrade to a modern, programmable thermostat resolves these issues and improves your home's comfort and efficiency.
What kind of HVAC maintenance do you recommend for Knoxville homes to prevent common issues like short cycling?
We recommend bi-annual preventative maintenance, ideally in spring and fall. Our service includes cleaning coils and components, checking refrigerant levels, inspecting electrical connections, testing safety controls, and calibrating your thermostat. This proactive care is crucial for our variable climate, as it helps prevent the dirty filters and component strain that lead to short cycling and system failures during peak seasons.
