As the temperatures drop, the last thing you want is for your HVAC system to stop working. If your heater suddenly fails, there are some simple troubleshooting steps you can take before calling in the professionals at Peaden for heater and AC repair. However, remember: it’s critical not to attempt actual repairs yourself. HVAC systems are complex, and untrained repairs can lead to bigger issues or even safety hazards.
1. Check the Thermostat Settings
Sometimes, the problem starts with the thermostat. Ensure it is set to “heat” mode and that the temperature is set higher than the current room temperature. If your thermostat runs on batteries, replace them, as low power can cause malfunctions. For smart thermostats, ensure they’re connected to your home’s Wi-Fi and functioning properly.
Additionally, double-check the thermostat’s schedule settings. A misconfigured schedule could make it seem like your heater isn’t turning on when, in fact, it’s just following an incorrect programming setting.
2. Inspect the Power Supply
Your HVAC system needs power to operate, even if it uses gas for heating. Head to your circuit breaker panel and ensure the breaker for your heating system hasn’t tripped. If it has, reset it once. Be cautious—if the breaker trips again, it could signal an electrical issue that needs professional attention.
For systems with an emergency switch, confirm it hasn’t accidentally been turned off. This switch is often located near the unit or on the wall by your furnace.
3. Examine the Air Filter
A dirty or clogged air filter can severely restrict airflow, causing your heater to malfunction or overheat. Check your HVAC system’s air filter and replace it if it’s dirty. Most filters need to be replaced every one to three months, depending on usage and household factors like pets or allergies
4. Check the Pilot Light or Ignition System
For gas furnaces, the issue might lie with the pilot light or ignition system. If your furnace has a pilot light, check to see if it’s lit. A blown-out pilot light might need to be relit, but proceed with caution—follow the manufacturer’s instructions carefully to avoid safety hazards.
For newer systems with electronic ignition, an issue with the igniter could prevent your furnace from working. Since this involves sensitive components, it’s best to leave repairs to the pros.
5. Ensure Vents and Registers Are Clear
Blocked or closed vents can disrupt airflow and put strain on your heating system. Walk around your home to ensure that all vents and registers are open and free from obstructions like furniture, rugs, or curtains.
6. Inspect the Outdoor Unit
If you have a heat pump, check the outdoor unit for signs of ice, debris, or other blockages. Heat pumps can freeze over during winter, especially in humid climates. While mild frost is normal, thick ice could prevent your system from functioning. Never attempt to remove ice with sharp objects—this could damage the unit. Instead, call a professional for assistance.
If you’ve tried these steps and your HVAC system still won’t work, it’s time to contact Peaden for AC repairs in Daphne. Attempting DIY repairs on your heating system can lead to costly damage or even pose safety risks, such as gas leaks or electrical fires.
