What to Do If Your Heater Won’t Turn On

When the temperatures drop and your heater won’t turn on, it’s easy to feel overwhelmed. Don’t worry—AC Comfort is here to help. While we’re always ready to assist with heating repair in Katy, TX, you can try a few simple checks before giving us a call. Let’s walk through some steps to troubleshoot the issue and get your home warm and cozy again.

That said, for most heating issues, calling a professional is the safest and fastest way to get your home warm again. Let’s walk through what you can do—and when it’s time to reach out for expert help.

Start With Your Thermostat

Your thermostat is often the easiest fix, so it’s a good place to start. Make sure it’s set to “heat” and the temperature is higher than the current room temperature. If you have a programmable or smart thermostat, double-check the settings or schedules to make sure they haven’t been changed. Dead batteries could also be the problem, so swap them out if needed.

If your thermostat seems unresponsive or you’re unsure about adjusting its settings, this is one of those times when a professional can help. A trained technician can inspect the thermostat and make sure it’s working properly with your system.

Check for Power Issues

Heating systems rely on power to function, whether it’s electricity, gas, or both. Start by checking your home’s circuit breaker panel for tripped breakers or blown fuses. If your heater is gas-powered, make sure the gas valve is open. However, if you detect a gas smell or suspect a leak, leave your home immediately and call your gas company.

While resetting a breaker is simple enough, other power or gas issues require a licensed professional. Don’t risk your safety—our team is here to help.

Replace the Air Filter

A dirty air filter can block airflow, causing your heater to shut down as a safety measure. If you can’t remember the last time you changed your filter, it’s a good idea to swap it out for a fresh one. Not only could this solve the problem, but it also helps your system run more efficiently and improves your indoor air quality.

If replacing the filter doesn’t solve the problem, the issue could involve the system’s internal components, and that’s to leave to an expert.

Look at the Pilot Light or Ignition System

For older gas furnaces, the pilot light might be out. Follow your system’s instructions to re-light it, but if it keeps going out, the thermocouple or gas supply might be the problem. Modern systems with electronic ignition can also experience failures that require professional attention.

When it comes to gas and ignition issues, we strongly recommend leaving this to a professional. Your safety and system integrity are too important to risk DIY fixes.

Unblock Your Vents

Blocked vents can disrupt your system’s airflow and performance. Make sure all vents are open and free of obstructions. While this is an easy fix, a professional can inspect your entire ductwork for hidden blockages or leaks that may be contributing to the problem.
