Should You Switch Between AC and Heat in the Fall? What King, NC Homeowners Should Know
Fall in King, NC can be a little unpredictable. One afternoon may feel like summer, while the next morning has you reaching for a sweatshirt. During September and early fall, it’s not unusual for homeowners to wonder whether they should keep the air conditioner running, turn on the heat, or switch back and forth depending on the weather. The good news is that your HVAC system is designed to keep your home comfortable through changing temperatures. However, there are a few things you should know as we transition from cooling season into heating season.
Is It Okay to Switch Between AC and Heat?
Yes. In most cases, there’s nothing wrong with using your air conditioning during a warm afternoon and switching to heat when temperatures cool down. However, avoid rapidly switching your thermostat from cooling to heating or vice versa. Give the system a few minutes after it shuts off before changing modes. This allows pressures within the system to equalize and helps prevent unnecessary strain on the equipment. If your thermostat has an Auto mode that allows you to set both heating and cooling temperatures, it can also help manage those changing fall temperatures without requiring constant adjustments.
Don't Overreact to a Cool Morning
That first chilly morning of the season can make it tempting to turn the heat up several degrees. But during early fall in North Carolina, outdoor temperatures can warm considerably by afternoon. Instead, choose a comfortable thermostat setting and allow your system to maintain it. Constantly making large temperature adjustments doesn't necessarily heat or cool your home faster and may lead to unnecessary energy use.
Pay Attention the First Time You Turn on the Heat
When you turn your heating system on for the first time after several months, you may notice a slight dusty or burning smell. In many cases, this is simply dust that has accumulated on heating components during the warmer months and should disappear fairly quickly. However, some warning signs shouldn't be ignored. Contact an HVAC professional if you notice:
- A strong burning or electrical odor that doesn't go away
- Unusual banging, grinding, or squealing noises
- Heat that won't turn on
- Air coming from the vents that never gets warm
- Frequent cycling on and off
- A sudden increase in energy usage
Finding a heating problem now is much better than discovering it during the first genuinely cold night of the season.
Check Your Air Filter After a Long Summer
Your HVAC system has worked hard through another hot North Carolina summer. Before heading into fall, take a look at your air filter. A dirty filter can restrict airflow, make your system work harder, and affect both heating and cooling performance. Since the same ductwork and blower are often used throughout the year, changing a dirty filter is one of the simplest ways to help prepare your home for the new season.
Clear Leaves and Debris Away From Outdoor Equipment
As leaves begin falling around King, keep an eye on the area surrounding your outdoor HVAC equipment. Leaves, grass clippings, sticks, and other debris can collect around the unit and interfere with proper airflow. Keep the area around your equipment clear, but leave any internal cleaning or disassembly to an HVAC professional. This is especially important for homes with heat pumps because the outdoor unit continues operating throughout the colder months.
Fall Is a Great Time to Catch Small HVAC Problems
The mild days between summer and winter give homeowners an opportunity to address HVAC problems before heating season is in full swing. Maybe your air conditioner struggled to keep up during the hottest part of summer. Perhaps you've noticed unusual noises, inconsistent temperatures, weak airflow, or a thermostat that doesn't seem quite right. Even if the problem isn't causing a breakdown yet, fall is a good time to have it checked. Taking care of a small issue now can help prevent an inconvenient loss of heat when temperatures drop later in the year.
