A system that never gets a season off

Your system cools for seven months here, then switches straight to heat for the other five. There is no real break in between. Summer afternoons average 90°F, and winter nights average 43°F, so the compressor and the heating side both put in a full year's work. Almost nine in ten homes here heat with electricity, which means the switch from cooling to heat matters more than it would somewhere that burns gas.

This area has recorded 20 damaging wind events over the past ten years. Wind that strong can throw debris into an outdoor unit or knock the power out. When the power drops and comes back, the system has to start itself back up, and a part that was already close to failing is more likely to give out on that restart.

Mississippi requires HVAC contractors to hold a state license.

The Mississippi State Board of Contractors is the body that licenses HVAC contractors in this state. That license belongs to the contractor, not to any single job, so the board tested and approved the person or company before they were allowed to take work, and it keeps a record of who holds that license now.

For a repair on a heating and cooling system, that license is what stands behind the person doing the work. It covers the contractor, not the repair itself, so there is no separate license issued for this job.

Why is my heat not working?
Most of the time it's the igniter or the flame sensor, not the furnace itself. If the system is electric, check the breaker first, since a tripped breaker is the quickest thing to rule out. If you hear the blower running but feel no warm air, or you hear nothing at all, that points to two different problems, and a contractor licensed through the Mississippi State Board of Contractors can tell you which one you have.
Why is my system running but not cooling the house?
Check the air filter first. A clogged filter chokes off airflow across the coil, and when that happens the coil can ice over and stop cooling the air even though the system keeps running. If the filter looks fine, the problem is more likely low refrigerant or a failing part inside the unit, and that calls for a licensed contractor to open it up and find out.
What can I check before calling for HVAC repair?
Start with the thermostat. Make sure it's set to heat or cool as needed and the batteries aren't dead. Check the breaker box for anything tripped, and pull the air filter to see if it's dark with dust or clogged. If the outdoor unit has leaves or debris packed against it, clear that away too. None of this costs anything to check, and if the system still isn't working after that, a licensed contractor will need to look at what's inside.
