Using your air conditioner during Sparks’ hot summer months keeps your home cool and comfortable. However, some common mistakes to avoid when using your AC can increase energy costs and reduce your system’s efficiency. By avoiding these errors, you’ll save money and prolong your AC’s lifespan. Here are the top five mistakes Sparks homeowners make with their air conditioners—and how to avoid them.

1. Ignoring Regular Maintenance
Many homeowners overlook annual AC maintenance, which can lead to costly repairs and reduced efficiency. These are mistakes to avoid when using your AC.
Why It’s a Mistake:
- Dirt and debris can clog components, forcing your system to work harder.
- Minor issues can go unnoticed and turn into major problems.
How to Avoid It:
Schedule professional maintenance every spring. A tune-up ensures your AC runs efficiently during Sparks’ hottest months.
2. Setting the Thermostat Too Low
Setting the thermostat to a very low temperature doesn’t cool your home faster. It only wastes energy and is among the key mistakes to avoid when using your AC.
Why It’s a Mistake:
- Your system works harder, leading to higher energy bills.
- Excess strain can shorten your AC’s lifespan.
How to Avoid It:
Set the thermostat to a comfortable temperature, typically between 74 and 78 degrees, for optimal energy savings.
3. Blocking Air Vents
Furniture, curtains, or rugs often block air vents, restricting airflow and making your AC less efficient. Addressing this is one of the mistakes to avoid when using your AC.
Why It’s a Mistake:
- Uneven cooling throughout your home makes your system work harder.
- Blocked vents increase energy usage and costs.
How to Avoid It:
Inspect vents regularly and ensure they’re clear of obstructions. This simple step improves airflow and comfort.
4. Forgetting to Change the Air Filter
A dirty air filter reduces your AC’s efficiency and impacts indoor air quality. This is another key mistake to avoid when using your AC.
Why It’s a Mistake:
- Restricted airflow forces the system to consume more energy.
- Poor air quality can trigger allergies or respiratory issues.
How to Avoid It:
Replace your air filter every one to three months, depending on usage and Sparks’ air quality.
5. Leaving Windows and Doors Open
Open doors or windows let warm air in and cooled air out, making your AC work harder. Hence, it is among the mistakes to avoid when using your AC.
Why It’s a Mistake:
- Cooling escapes, causing your system to run continuously.
- Higher energy bills result from wasted cooling.
How to Avoid It:
Keep windows and doors closed when your AC is running. Use weather stripping to seal any gaps.
