A properly maintained furnace helps avoid breakdowns, reduces energy consumption, and keeps your home warm without unexpected costs.
The furnace/air handler works hardest during the coldest and hottest days of the year, and you don’t want the system to fail during those crucial times.
1. Schedule an Annual Furnace Tune-Up and Cleaning
A furnace tune-up should be a yearly ritual to ensure your system is running at peak performance. During a professional tune-up, a technician will inspect the entire system, address minor issues before they become major problems, and clean the AC Coils and Secondary Heat Exchanger. Over time, these parts can accumulate dust and debris, sagnifically reducing efficiency. Cleaning them ensures the furnace operates efficiently, saving energy and preventing premature wear on the system.
Additionally, the technician can ensure your thermostat is programmed and functions correctly. If it's not working as expected, consider upgrading to a programmable or smart thermostat, which can adjust automatically based on your schedule, saving energy and keeping your home comfortable.
2. Air Duct Cleaning
Your air ducts play a crucial role in your furnace’s performance. Over time, dust, dirt, pet hair, and other debris accumulate in the ducts, obstructing airflow and forcing your furnace to work harder to circulate air throughout the home. This can result in uneven heating and higher energy bills.
Scheduling regular air duct cleaning ensures that your ducts are free from blockages, improving airflow and furnace efficiency. It also helps to improve indoor air quality by removing allergens and dust particles from the air circulating in your home. If you haven’t cleaned your ducts in a while or notice a buildup of dust despite regular cleaning, it may be time to schedule a professional duct cleaning service.
3. Change Your Air Filter Regularly and Choose the Right MERV Rating
One of the easiest and most cost-effective ways to maintain your furnace is by changing the air filter regularly (make sure the airflow arrow on the filter points towards the furnace or air handler). A dirty filter restricts airflow, making your furnace work harder and reducing its efficiency. However, it’s essential to understand that the MERV (Minimum Efficiency Reporting Value) rating of the filter you use plays a big role in both furnace efficiency and air quality.
Filters with a MERV rating between 5 and 8 provide an excellent balance between filtration and airflow, especially if your air duct system is clean. They effectively trap common household particles such as dust, pet dander, and pollen, while still allowing the furnace to circulate air without overloading the system.
Filters with higher MERV ratings (10 and above) can offer superior filtration but may slow down airflow, making the furnace work harder to heat or cool your home, which could increase energy use. Unless you have allergies or asthma, or your ducts are in poor condition, there’s no need to opt for a high MERV filter.
4. Clear Blockages from Vents and Registers
Blocked vents and registers can significantly hinder airflow in your home. Furniture, rugs, or curtains blocking your vents can make it difficult for your furnace to distribute heat evenly throughout the space. Ensure that all vents and registers are clear of obstructions to allow optimal airflow. This simple step can help your furnace heat your home more effectively and efficiently.
5. Pressure Test Your Air Duct System
If, after completing all the regular maintenance steps listed above, you still feel that your furnace is taking too long to heat or cool your home, it may be time to have a professional perform a Pressure Test on your air duct system. This test measures the air pressure inside your ducts to identify any leaks or blockages that could be causing poor airflow. The test is crucial because even small leaks or blockages in the ducts can significantly reduce efficiency and lead to higher energy costs. A pressure test will help pinpoint the exact areas that need attention, allowing you to take the necessary steps to improve airflow and furnace performance.
Final Thoughts
By following these steps, you can keep your furnace running efficiently and extend its lifespan. From regular tune-ups to choosing the right air filter and ensuring clean ducts, proper maintenance is key to ensuring your furnace performs optimally. If you still have concerns about airflow or furnace efficiency after completing these tasks, a professional pressure test can help identify any lingering issues with your ductwork.
With the right care and attention, your furnace will provide reliable warmth throughout the winter without costing you extra in energy bills. It will also help prevent costly repairs or furnace replacements. The furnace/air handler works hardest during the coldest and hottest days of the year, and you don’t want the system to fail during those crucial times.
If you need help with furnace maintenance, air duct cleaning, or pressure testing, don’t hesitate to reach out to a trusted professional. They can guide you through the best practices for keeping your home comfortable and your furnace running smoothly all season long!
