Check the Thermostat
To start, make sure your thermostat is instructing your heat to turn on.
- Replace the batteries if the display is blank. If the digital display is mixed up, the thermostat could need to be changed.
- Make certain that the button is switched to “heat” as opposed to “off” or “cool.”
- Make sure the program is displaying the correct day and time and is set to “run.” If you’re having a hard time turning off the program, set the temperature with the up/down arrows and using the “hold” button. This will make the furnace to turn on if thermostat scheduling is an issue.
- Turn the temperature setting to 5 degrees warmer than the room temperature.
If your heater hasn’t started within a couple minutes, make sure it has power by toggling the fan switch from “auto” to “on.” If the fan doesn’t operate, your heater may not have power.
If you utilize a smart thermostat—like one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Refer to the manufacturer’s website for help. If you’re still unable to get your Wi-Fi thermostat to work, reachl us at 515-207-6569 for heating and cooling service.
Put in a New Air Filter
When it comes to heater problems, a dirty, clogged air filter is frequently the top offender.
If your filter is too grungy:
- Your heater won’t stay on, or it could get too warm from reduced airflow.
- Your utility costs could increase because your heating system is operating too often.
- Your heat could break down prematurely because a dirty filter causes it to overwork.
- Your heating can be cut off from power if an extremely clogged filter is the cause of a tripped breaker.
Depending on what model of furnace you have, your air filter will be inside the blower compartment of your heater, an attached filter case or wall-mounted return air grille.
To replace your filter:
- Turn off your furnace.
- Pull out the filter and tilt it toward the light. If you can’t notice light through it, get a new one.
- Insert the new filter with the arrow motioning toward the heating system to keep damage from happening.
Flat filters ought to be replaced once a month, while pleated filters should last about three months. You could also use a washable filter that you can use for about 10 years. If you have children or pets, you could have to put in a new filter sooner.
To make the procedure smoother down the road, use a permanent writing tool on your furnace exterior or ductwork to show the airflow direction and filter size.
