HVAC Repair Jonesboro AR | Call Williams Mechanical Services

In our Jonesboro climate, with its seasonal dust and pollen, we recommend checking your filter monthly and replacing standard 1-inch filters every 1-3 months. A clogged filter makes your system work harder, reducing efficiency and increasing wear. Our technicians can assess your specific system and home environment during a maintenance visit to recommend the perfect schedule for you.

Start with the basics: check that the display is on, ensure it's set to 'heat' or 'cool' (not 'off'), and replace the batteries if it's a battery-operated model. Also, make sure no furniture or curtains are blocking the thermostat. If it's still unresponsive or inaccurate, it could be a wiring issue or need recalibration. Our technicians can diagnose and repair all thermostat problems to restore precise temperature control in your home.

Our comprehensive maintenance service is designed to prevent common local issues. We perform a full system inspection, clean critical components (like the evaporator and condenser coils), check refrigerant levels, tighten electrical connections, lubricate moving parts, and test the thermostat and safety controls. This proactive care helps improve efficiency, prevent unexpected breakdowns, and extend the life of your HVAC system, saving you money and hassle.
