Eleven months of work, most years
Your system in Nixa only gets a break in spring and fall. Heat runs October through April, and the furnace is lighting on nights that average 26°F. Cooling takes over in June and runs through September, with afternoons hitting 87°F. That is eleven months where something in the system is working most days, and that much runtime wears on the parts that start the cycle, the igniter in the furnace and the capacitor in the AC.
Storms add another kind of strain. The area has logged 143 damaging wind events and 11 winter storms over the past ten years, and close to a fifth of Missouri households lost power for a full day or more in 2024. A storm knocks the power out, and when it comes back, that is often the moment a weak part fails and the system does not start back up.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker and any switch that looks like a light switch near the furnace. If it has power and still won't fire, the igniter is a common failure, it wears out and stops glowing hot enough to light the burners. On nights that drop to 26°F, a furnace that won't start needs a contractor out soon, not next week.
- Why is my system running but not cooling the house?
- The blower is moving air but something is stopping that air from carrying heat out of the house. A dirty filter is the first thing to check, a clogged one starves the coil of airflow and it can ice up. If the filter is clean and the air coming from the vents feels warm, the refrigerant charge is likely low, and that calls for a contractor with gauges to find where it's leaking out.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and the setting first, it sounds obvious but it's the most common false alarm. Check the breaker box for a tripped breaker, especially after a storm. Pull the filter out and hold it up to a light, if you can't see light through it, replace it. Look at any outdoor unit for leaves, ice, or debris blocking the sides, and clear it if you find any. If none of that explains it, a contractor will need to look at the actual parts inside the unit.
