Fall Heating Checklist: Prep Your Covington Heat Pump for Winter Snaps

The simplest and most important step is to run the system in heating mode on a cool morning in October or November, long before a real cold snap. Set the thermostat above room temperature and confirm you actually get warm air from the vents within a few minutes.

If the air is lukewarm, if the backup heat kicks on immediately, or if you smell a faint burning odor that does not clear after the first cycle, note it now. A daytime diagnostic in November beats a midnight no-heat call in January every time.

A heat pump does not burn fuel, it moves heat, running your AC in reverse to pull warmth from outdoor air into the house. When it gets near freezing, the outdoor coil can frost over and the unit runs a defrost cycle, briefly blowing cooler air while it clears the ice. That is normal.

On the coldest Northshore nights, electric backup heat strips supplement the heat pump. Those strips draw a lot of power, so if your system leans on them when it should not, your December bill spikes. A fall check confirms the heat pump is doing the heavy lifting and the backup only fills in when it should.

Some of these you can do yourself, others are part of a professional visit.

Because the heat pump absorbs heat from outside air, the outdoor unit runs in winter too, unlike a furnace home. Keep it clear of leaves and yard debris, and never stack anything against it or cover it while it is in use. Airflow around that coil is what lets it pull heat on a cold night. If ice builds up and never clears, that is a defrost problem, not a normal cycle, and it needs service.

Louisiana cold snaps are short but sharp, and they always seem to arrive on a holiday weekend. A fall heat pump check catches a weak reversing valve, a failing capacitor, or dead backup strips while it is still a scheduled repair. If your system struggled last winter, or you have never had the heating side checked, call HVAC Covington LA at (327) 210-5999. We will make sure the heat is there before the first cold front does the testing for you.

A Covington heat pump loafs through summer in cooling mode and then, on the first real cold snap, is suddenly asked to reverse and heat for the first time in months. Components that sat idle, the reversing valve, the defrost control, the electric auxiliary heat strips, are exactly the parts most likely to fail on that first cold morning because they have not moved since spring. Fall is when you exercise and verify them, before you actually need them. This is different from a northern climate where the furnace runs constantly and problems surface gradually.

The auxiliary heat strips deserve special attention here. Because they run so rarely on the Northshore, a failed strip or a tripped high-limit often goes unnoticed until a homeowner feels cold air during a defrost cycle in January. Testing that backup heat energizes in the fall, along with confirming the reversing valve shifts cleanly into heat mode, prevents the classic no-heat call on the coldest night of the year when every technician in the parish is booked solid.

Run through this before the first cold front so a surprise freeze does not catch your system unprepared.
