While Texas is known for its heat, homeowners in the Combine area know that owning a furnace or heat pump is essential for comfort during the winter months. They also know that replacing one of these systems is a costly investment they would prefer to delay.
Fortunately, with the proper care and a few preventive steps, you can keep your system running smoothly for years to come. In this post, we’ll walk you through practical tips to help extend the lifespan of your HVAC system and keep it operating efficiently. We hope these strategies will help protect your investment and keep your home comfortable all year long.
1. Regular Filter Changes Are Crucial
One of the simplest yet most important tasks you can do is regularly change your HVAC system’s air filter. Air filters trap dust, pet dander, and other airborne contaminants, preventing them from clogging your system. When filters are dirty, airflow becomes restricted, causing the system to work harder and potentially overheat.
How Often Should You Change Filters?
- Basic Filters: Replace every 30-90 days.
- High-Efficiency Pleated Filters: These last longer but require periodic checks to ensure they do not restrict airflow.
Using the correct filter is essential. Some homeowners think upgrading to a high-efficiency filter is always better. Still, if the filter restricts airflow too much, it can strain the motor. To maximize performance, use a filter with a suitable MERV rating (around 8 to 12 for most residential systems).
2. Clear the Area Around Your Unit For Better Airflow
You should always make sure your HVAC unit has enough space to “breathe”. Items stored near your indoor unit or debris around an outdoor unit can obstruct airflow, causing your system to work harder and wear out faster.
Tips for Indoor Units
- Keep at least 18 inches of clearance around the furnace.
- Avoid stacking items on top of or near the unit; this includes shelving or storing items on ductwork.
Tips for Outdoor Units
- Clear away leaves, grass clippings, and debris.
- Trim nearby bushes or trees to avoid blocking airflow.
- If possible, place your outdoor unit in a shaded area to reduce sun exposure and prevent it from overheating.
3. Reduce the Load on Your HVAC
Poor insulation and drafty windows or doors force your HVAC system to work harder just to keep your house the temperature you want. By sealing leaks and adding insulation, you can improve your home’s energy efficiency and reduce the strain on your HVAC.
Steps to Improve Insulation
- Seal Windows and Doors: Apply weatherstripping around doors and windows to prevent cold air from entering in the winter or escaping in the summer.
- Check Attic Insulation: Since heat rises, having an attic that isn’t adequately insulated can cost you a ton of lost energy. Upgrading insulation here can help reduce HVAC usage.
- Inspect for Duct Leaks: Leaky ducts are a significant source of energy waste, often causing 25-40% loss. Regular duct inspections and sealing can make a substantial difference.
A well-insulated home means your HVAC doesn’t need to work as hard, leading to reduced wear and longer system life.
4. Optimize Your HVAC’s Running Time
Frequent thermostat adjustments can put a lot of stress on your HVAC system. With a programmable or smart thermostat, you can set your system to run only when needed, ultimately extending its life.
Benefits of Programmable Thermostats
- Automatic Adjustments: Program it to lower the temperature at night or during work hours, reducing the load on the system.
- Smart Features: Many smart thermostats allow remote control, so you can adjust the temperature before arriving home without leaving your HVAC running all day.
- Energy Savings: By setting consistent, energy-efficient temperatures, you’ll save on energy bills while reducing system wear.
In Texas, homeowners can see temperatures can vary significantly between day and night. A programmable thermostat can be a game-changer, as it will help improve comfort and add years to the life of the system.
5. Keep Vents and Ducts Clear
Blocked vents and ductwork restrict airflow, making your HVAC system work harder to distribute air evenly throughout your home. Ensure all air vents remain unblocked by furniture, curtains, or other household items.
Tips for Maintaining Clear Vents
- Keep furniture at least a few feet away from air vents.
- Check for and remove any blockages, especially in seldom-used rooms.
- Schedule regular duct cleanings if you notice dust accumulating quickly.
Restricted airflow can lead to uneven heating or cooling, putting extra stress on the blower motor and shortening its lifespan.
6. Practical Temperature Settings
During the frigid Texas winter, it can be tempting to set the thermostat very high. However, doing so makes the HVAC system run continuously and, naturally, increases wear. Instead, set reasonable temperatures that are achievable and efficient for your system.
Additional Tips to Lighten the Load
- Use ceiling fans to help circulate air. There is a button that reverses the direction the fan spins to help circulate the warmer air near the ceiling.
- Limit large temperature swings by keeping your thermostat at a moderate setting, which avoids the need for your HVAC to constantly turn on and off.
These simple adjustments can reduce energy consumption and help keep your HVAC system in top shape.
7. Start Strong for Long-Term Success
An HVAC system’s life and efficiency depend heavily on correct installation. A poorly installed system may suffer from airflow problems, improper sizing, and rapid wear on components. If you are installing a new HVAC system, CAST Heating & Air is here to help. As a licensed professional, we can make sure that you start with a solid foundation for years of comfort.
Why Proper Installation Matters
- Correct Sizing: A system that is too large will short-cycle, while a system that is too small will overwork itself.
- Efficient Ductwork Design: Properly sized and sealed ductwork prevents pressure issues and maintains balanced airflow.
- Safety and Compliance: Our licensed technicians will make sure the installation complies with safety codes and standards, reducing the risk of future issues.
8. Protect Indoor Air Quality and Efficiency
Dust, pet hair, and other debris accumulate in your ductwork over time, affecting indoor air quality and reducing airflow. Routine duct cleaning, especially if you have pets or live in a dusty area, can help keep your HVAC system efficient and your indoor air healthier.
Signs Your Ducts Need Cleaning
- Visible Dust on vents or registers.
- Frequent Filter Replacements due to dust.
- Unusual Odors when your HVAC is running.
Duct cleaning improves indoor air quality and ensures your system doesn’t have to work harder than necessary, extending its lifespan.
9. Prep for Every Season
Many Texas homeowners schedule tune-ups only when they notice issues. However, seasonal maintenance ensures your HVAC system is prepared for extreme temperatures in both summer and winter.
Much like a car, your HVAC system needs regular check-ups to perform well. Professional HVAC maintenance is essential for preventing minor issues from becoming costly repairs and keeping your warranty valid.
Key Tune-Up Benefits
- Detect Early Issues: Technicians can address minor problems before they become costly repairs.
- Optimize Settings for the Season: For instance, adjusting the blower speed and gas pressure can help the system operate at peak efficiency.
- Long-Term Savings: Preventative care reduces energy bills, enhances performance, and prolongs system life.
When you’re ready for a tune-up, CAST Heating & Air Conditioning is here to help keep your HVAC in peak condition so you’re prepared for whatever the weather brings.
