As a homeowner in Nebraska, you know how unpredictable the weather can be, and how crucial it is to maintain your home comfort systems through the changing seasons. Yet, whether you’re a first-time homeowner or have been living in your house for years, it’s common to have questions about how to best take care of your HVAC system for year-round comfort. Here are answers to 8 frequently asked HVAC maintenance questions.
Common HVAC Maintenance Questions
1. When Should I Replace My Air Filter?
Replacing your HVAC system’s air filter is crucial for maintaining air quality and system efficiency. It’s typically recommended to change your air filter every 1-3 months, depending on usage and the type of filter. If you have pets or live in a dusty area, consider replacing it more frequently.
2. Why Is My Air Conditioner Blowing Warm Air?
If your air conditioner is blowing warm air, the issue could be a dirty air filter, low refrigerant levels, or a malfunctioning thermostat. Start by checking the filter and replacing it if necessary. If the problem persists, you may need to call a professional to check for refrigerant leaks or a faulty compressor.
3. How Can I Improve My HVAC System’s Efficiency?
There are several ways to improve your HVAC system’s efficiency. Regularly change the air filter, clean the condenser coils, and make sure the system is properly sealed. Additionally, consider upgrading to a programmable thermostat that adjusts the temperature based on your schedule, reducing unnecessary energy consumption.
4. When Should I Schedule HVAC Maintenance?
It’s ideal to have your HVAC system serviced twice a year—once in the spring for your air conditioner and once in the fall for your furnace. A professional technician will clean and inspect the system, check for potential issues, and ensure that it’s running efficiently, which can prevent costly breakdowns.
5. How Can I Tell If My HVAC System Needs Repairs?
Common signs that your HVAC system may need repairs include unusual noises (like banging or screeching), inconsistent temperatures, high energy bills, or poor airflow. If you notice any of these issues, it’s important to call a professional technician to diagnose and fix the problem before it gets worse.
6. What’s the Ideal Thermostat Setting for Winter and Summer?
During winter, set your thermostat to 68°F when you’re home and 60-65°F when you’re asleep or away. In summer, aim for 75°F when you’re home and a higher setting when you’re gone. These settings help balance comfort and energy efficiency, reducing your heating and cooling costs.
7. Should I Close Vents in Unused Rooms?
While it may seem like a good idea to close vents in unused rooms to save energy, it’s actually counterproductive. Closing vents can cause pressure imbalances and force your HVAC system to work harder, which may decrease efficiency. Instead, try using ceiling fans or adjusting your thermostat to maintain a comfortable temperature.
8. Why Is My Heater Making Strange Noises?
If your heater is making strange noises like rattling, squealing, or banging, it could be due to issues with the blower, ducts, or burners. A squealing noise may indicate a problem with the blower belt, while rattling could point to loose parts. If you hear any unusual sounds, it’s important to call a professional technician to inspect and repair your system.
