Questions and Answers

My AC in Kenner keeps turning on and off every few minutes. What could be causing this short cycling?

This is a common issue we see in the Kenner area, often caused by an oversized unit, a dirty air filter restricting airflow, or a refrigerant leak. Short cycling stresses your system and hikes up energy bills. Our technicians will perform a thorough diagnostic to pinpoint the exact cause—be it a simple filter change, a coil cleaning, or a refrigerant charge—and get your AC running smoothly and efficiently again.

My thermostat seems to be malfunctioning and my house feels unevenly heated or cooled. What should I do?

An unreliable thermostat is a frequent culprit for comfort problems in Kenner homes. It could be due to faulty wiring, dead batteries, location (like direct sunlight), or simply being outdated. We can troubleshoot your current thermostat, check the wiring to your HVAC system, and, if needed, recommend and install a modern, programmable, or smart thermostat. This upgrade can improve comfort and help you save on energy costs.

What regular maintenance can help prevent these common AC problems in our Louisiana climate?

Our intense humidity and heat in Kenner put extra strain on HVAC systems. We recommend annual preventative maintenance, which includes cleaning coils, checking refrigerant levels, calibrating thermostats, and inspecting electrical components. This proactive service helps catch small issues—like those that cause short cycling or thermostat errors—before they become major, costly repairs, ensuring your system runs reliably all season long.
