Twelve months of work, in weather that swings hard
Your system does not get an off season here. Heat runs October through April, then cooling takes over for May through September. There is almost no month where something in the house is not calling on it.
Winter nights averaging 23°F mean the furnace cycles on and off for hours at a stretch, and every start puts wear on the igniter and the ignition control. Summer afternoons near 86°F keep the air conditioner's compressor under load most of the day, and that is where a struggling unit tends to fail first. Two-thirds of homes here heat with electricity, so a breaker problem or a bad heat strip shows up as a cold house, not just a quiet one. Storms take that power out often enough that almost one in five Missouri households went at least a day without it last year, and a system that was already borderline does not always come back cleanly once the power does.

- Why is my heat not working?
- Most often it comes down to power, fuel, or airflow. Check your thermostat is set to heat and the temperature is above room temperature, then check your breaker panel for a tripped switch. If you have a gas furnace, look at the door panel, it has to be seated right or the unit won't fire. With over two-thirds of homes here heating with electricity, a tripped breaker after a storm is a common cause, and at 23°F on a winter night this is not something to leave until morning.
- Why is my system running but not cooling the house?
- If air is moving but it is not cold, the first thing to check is the filter. A clogged filter starves the coil of airflow, and when that happens the coil can ice over and stop cooling altogether even though the blower keeps running. Check your outdoor unit too, the fan should be spinning and the area around it clear of leaves or grass clippings. If the filter is clean and the outdoor unit is running but the air still is not cold, the system likely needs a contractor to check refrigerant levels and the coil itself.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Confirm it is set to the right mode, heat or cool, and that the set temperature is actually above or below the room temperature so the system has a reason to run. Next check your breaker panel for anything tripped, especially after one of the wind storms this area sees, and check the filter, since a dirty one can cause problems on both the heating and cooling side. If the system still is not working after that, a contractor will need to look at it directly, since anything past this point involves opening up the equipment.
