Eleven months of work a year on your system
In Jackson your system barely gets a rest. Heat runs November through March, then cooling takes over from May through October. That kind of year round work wears on the parts that start the system up, the igniter, the capacitor, the contactor.
Summer afternoons here average 91°F, so the compressor works hard most days from May to October. Winter nights average 38°F, mild compared to a lot of places, but the system still cycles on and off through those five heating months. More than half the homes in this area heat with electricity, so when a heat pump or electric furnace struggles, there is no backup warming the house while it waits on a repair.
The power itself is not always reliable. Statewide, 3 in 10 households went at least 24 hours without power in 2024. Most systems restart on their own once power comes back, but if a part was already failing, an outage is often when it finally gives out.

Mississippi requires HVAC contractors to hold a state license.
Mississippi licenses HVAC contractors through the State Board of Contractors. That license is tied to the contractor, not to any single job, so the same license covers this repair and the next one a contractor takes on.
For a heating and cooling repair, that license is what stands behind the work. It is a record of the contractor, not a separate check on this particular job.

- Why is my heat not working?
- Start with the thermostat. Make sure it's set to heat, not just fan, and that the temperature you want is above the room temperature. If that's fine, check your breaker panel. More than half the homes here heat with electricity, and a tripped breaker will shut the whole system down with no warning. If the breaker's fine and you still have no heat, listen for the system trying to start. A furnace that clicks but won't light usually has an igniter problem. One that hums but the blower never comes on is a different issue. Either way, a contractor will need to look at it, especially with lows averaging 38°F here from December through February.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice over and stop cooling even though the system is running. Turn the system off for an hour to let any ice melt, then swap the filter and try again. If it still blows air that isn't cold, the problem is likely low refrigerant or a failing compressor, and that's a contractor job. With afternoons here averaging 91°F, a system that's only moving air and not cooling it needs attention soon rather than later.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first. A dead battery or a setting bumped to the wrong mode causes a lot of no-heat and no-cool calls that aren't actually broken systems. Next, check your breaker panel and any switch near the furnace or outdoor unit, since a flipped switch looks just like a dead system. Look at the air filter and replace it if it's dirty. If the outdoor unit is involved, check that leaves or debris aren't blocking it. If you've checked all of this and the system still isn't working, a licensed contractor can diagnose what's actually wrong. Mississippi requires that license for good reason, since diagnosing refrigerant, wiring and gas issues correctly takes training you shouldn't have to have as a homeowner.
