The most common fall HVAC problems are refrigerant leaks, thermostat issues, clogged drain lines, duct leaks, a tripped breaker, dirty coils, poor airflow, uneven temperature distribution, blown fuses, dirty filters, strange noises, ignition problems, and continuously running blower.
It is essential to know what issues to expect with the upcoming season. The classic problems homeowners often face during fall are listed here, along with an explanation of how to prepare your HVAC and what is the best setting for the season. /start reading and find out!
Can I Run The Air Conditioner In The Fall?
Yes, you can run the air conditioner in the fall. It is up to you and the temperatures of your region to decide whether you want to continue using the air conditioner or save it for more extreme seasons.
What Is The Best AC Setting For Fall?
The ideal air conditioner setting for fall is between 70 and 78 degrees (around 21 to 25ºC). You can vary this setting according to the temperature outside! Another tip is to invest in a programmable thermostat, a smart home appliance that makes your system even more efficient.
What Are The Common Failures Of HVAC Systems In The Fall?
Frequent HVAC failures in the fall include refrigerant leaks, thermostat issues, clogged drain lines, duct leaks, a tripped breaker, dirty coils, poor airflow, uneven temperature distribution, blown fuses, dirty filters, strange noises, ignition problems, and continuously running blower.
Discover the details of each issue in the list below.
1. Dirty Filters
When HVAC filters become clogged with dust, dirt, and other debris, airflow is restricted, making the system work harder to heat or cool your home. If not addressed regularly, it can reduce efficiency, higher energy bills, and even system breakdowns.
2. Strange Noises
Unusual noises, such as banging, clanking, or squealing, coming from your HVAC system often indicate mechanical issues. A noisy AC unit could be due to loose or damaged parts, such as belts, motors, or fans, and should be checked by a professional to prevent damage.
3. Ignition Problems
Ignition problems are common in the fall, as the furnace may not have been used in months. Issues could arise from dirty burners, a faulty ignition switch, or a malfunctioning pilot light, leading to a lack of heat production.
4. Faulty Thermostat
A faulty thermostat often causes HVAC systems to run inefficiently, leading to uneven temperatures, short cycling, or not turning on or off at the right times. Calibration issues, sensor problems, or simply an outdated thermostat can cause this.
5. Clogged Drain Lines
HVAC systems produce condensation, which is usually drained away through a series of pipes. In the fall, leaves, dirt, and other debris can clog these drain lines, leading to water backup, leaks, or even water damage if the problem is severe.
6. Refrigerant Leaks
Though more common in cooling systems, refrigerant leaks can still be an issue in heat pumps during the fall. A refrigerant leak reduces the ability to regulate temperature, reducing efficiency and potentially causing the system to overheat or freeze.
7. Dirty Coils
The evaporator and condenser coils in your home's HVAC system can accumulate dirt and debris, especially after the summer months. Dirty coils reduce the absorption or release of heat, leading to increased energy consumption.
8. Blown Fuses
Fuses protect the electrical components of your HVAC system. A blown fuse can likely cause the system to shut down, often due to electrical issues, such as a short circuit, overload, or a problem with the transformer or compressor.
9. Blower Working Continuously
If your blower fan runs continuously, it may be due to a malfunctioning thermostat, a stuck relay, or a fan limit switch that is not working correctly. You may notice it by the non-stop sound it produces. This issue leads to excessive wear on the blower motor and higher energy bills.
10. Duct Leaks
Ductwork carries heated air throughout your home, and leaks can occur over time, especially in older systems. These leaks allow heated air to escape into unconditioned spaces, like attics or crawl spaces, which leads to uneven heating, higher energy bills, and reduced comfort.

11. A Tripped Breaker
Your HVAC system draws a significant amount of power, and if there is a sudden surge or an issue with the wiring, the circuit breaker may trip to protect the system. A tripped breaker will cause the system to shut down until reset, and if it trips frequently, it may indicate a deeper electrical problem.
12. Poor Airflow
Poor airflow results from various issues, including dirty filters, blocked vents, duct leaks, or malfunctioning blower motors. When airflow is restricted, your HVAC system has to work more to maintain the desired temperature, which can lead to costly energy bills and reduced comfort.
13. Uneven Temperature Distribution
If some rooms in your home are warmer or cooler than others, it may be caused due to uneven temperature distribution. It might happen due to duct leaks, poor insulation, or a faulty thermostat. A balanced HVAC system operating correctly keeps consistent temperatures!
How Do I Prepare My HVAC For Fall?
To prepare your HVAC for fall, check and replace filters, clear away debris, clean the coil, clean vents and ducts, find and seal air leaks, insulate the pipes, invest in a programmable thermostat, consider an upgrade, and schedule an HVAC inspection.
