How Often Should Your Air Filter Be Changed?

December 19, 2023

It's important to take care of your HVAC system in order to keep it running well. One way to maintain your system is by regularly changing the air filter. A clean air filter not only helps your system run more smoothly but also more efficiently. How often you should change your air filter depends on several factors, including the filter type, the size of your home, how often you use your HVAC system, whether you have pets or allergies, and seasonal conditions.


Type of Filter

There are two types of air filters: fiberglass and pleated. Fiberglass filters are cheaper but need to be changed every 30 days and are not as effective at capturing dust and other particles. Pleated filters are more expensive but are better at capturing particles and can last up to 90 days. Most filters come with guidelines on how frequently they should be replaced.


Home Type

The size of your home and how often you use your HVAC system are also important factors. Larger homes require more air filtration than smaller homes, and homes that use their HVAC system year-round will need more frequent air filter changes than vacation homes that only use their system a few times a year.


Pet

Pets can also affect your air filter. They release hair and dander into the air and bring in additional dirt, pollen, and other particles from outside. If you have pets, it's a good idea to check your filters every 1 to 2 months and replace them when they're dirty.


Allergies

If you or your family suffers from allergies, it's important to check your air filters regularly and change them every 30-50 days to prevent them from becoming clogged and exacerbating your allergy symptoms.


Seasons

Seasonal conditions also play a role. During the spring and fall, your HVAC system typically runs less frequently than during the rest of the year, so your filter won't become as dirty as quickly. However, during the summer and winter, your system runs more frequently, causing your filter to collect more dust and other contaminants. If your home experiences these seasonal conditions, you won't need to change your air filter as often during the spring and fall. It's important to note that allergens are typically higher during these seasons, so not running your HVAC system could ultimately worsen your allergies since the particles won't be trapped in the filters. An option to prevent this would be to keep your fan on during these times so the air in your home continues to be filtered and the air quality improves. If you choose to keep the fan on, you'll need to maintain your air filters as you normally would throughout the year.


In conclusion, the frequency of air filter replacements depends on the type of filter you use and the lifestyle of those in your home. Follow the guidelines of the filters you purchase and use your best judgment to determine when to change out the air filters in your home.

How to Take Care of Your HVAC During Winter

January 10, 2025
With freezing temperatures in the forecast and stormy winter weather on the horizon, it's essential to know how to care for your HVAC unit during snow and ice conditions. While most units are designed to endure harsh winter weather, being mindful of a few key factors can help prevent a mid-winter breakdown. Ensure Your Unit Isn’t Buried Under Snow A unit buried under snow can lead to various problems. Your HVAC system requires airflow to function effectively, and excessive snow coverage can restrict this airflow. If you find your unit covered in snow, carefully clear it away to avoid damaging the unit or the internal fans. As a general rule, maintain at least 18 inches of clear space around the unit year-round. If there is ice on top, gently break it away by hand. Avoid pouring warm water on the ice to melt it, as any water that seeps inside can refreeze, potentially causing more damage. Check That Your Furnace Exhaust Isn’t Blocked For those with gas furnaces, it's crucial to ensure that the exhaust vent is not obstructed. A blocked exhaust can cause your furnace to stop working and may even lead to dangerous carbon monoxide leaks into your home. Snow or ice can often block this exhaust pipe. If your furnace begins to behave unusually, contact a professional to diagnose the issue before it escalates into a larger problem. Additionally, for gas furnace owners, remember to check your fire and carbon monoxide alarms as part of your winter HVAC maintenance. It’s always better to be safe than sorry. Inspect Your Air Filter Regularly checking your air filters is essential. During the coldest months, your HVAC unit operates more frequently, pulling in increased amounts of air through the filter. This results in more dust, dirt, and debris accumulating, making regular filter checks and replacements even more critical. Keep Your Unit Clear of Melting Snow and Ice Be mindful of gutters or water runoff that may drip onto or into your HVAC unit. In freezing temperatures, this can create a significant risk for your system. The real concern is not that the snow or ice from above is dripping, but rather the drips that may enter the unit and then refreeze. While HVAC units are built to withstand winter weather, ice forming inside the unit can lead to problems that might eventually result in a system breakdown. Taking proactive steps to care for your HVAC system during icy weather is crucial for ensuring its efficiency and longevity. Regular maintenance can prevent minor issues from escalating into major problems that may require costly repairs. By keeping your unit clear of snow and ice, checking exhaust vents, inspecting air filters, and monitoring the surrounding environment, you can help your HVAC system operate smoothly throughout the winter months. Remember, it's always wise to enlist the help of a professional if you're uncertain about any maintenance tasks or if you notice any irregularities in your HVAC system's performance. Doing so can provide peace of mind and ensure that your home remains warm and comfortable, even during the harshest winter conditions. Trust B.

Frozen Pipes and Your HVAC

December 13, 2024
As we enter the chill of winter, it’s essential to check that your heating system is functioning effectively. Not only does this provide warmth for your home or business, but it also helps shield your pipes from freezing. Managing Frozen Pipes and Safeguarding Your HVAC System During Winter In the colder months, one frequent issue homeowners encounter is pipes freezing. While the potential damage to plumbing is often top of mind, the implications for your HVAC system are sometimes overlooked. When pipes freeze or burst, they can cause water leaks, obstruct airflow, and lead to costly repairs to your heating system. Fortunately, taking proactive measures can help you avoid these complications before they arise. Why Frozen Pipes Are a Concern for Your HVAC System Frozen pipes can disrupt your HVAC system in various ways. When water freezes inside the pipes, it can create blockages or even lead to bursts, resulting in leaks that can harm your furnace or air handler. Additionally, some HVAC systems function on a closed-loop principle involving water or refrigerant, meaning that any plumbing complications might hinder your system’s performance and efficiency. Strategies to Prevent Pipe Freezing in Your Home To keep your pipes and HVAC system safe during winter, consider the following preventive actions: Insulate Exposed Pipes: Pipes situated in unheated spaces like basements, attics, or crawlspaces are more susceptible to freezing. Use insulation to help maintain a consistent temperature around them. Keep the Heat Running: If you plan to be away from home for any length of time, set your thermostat to a minimum of 55°F to prevent drastic indoor temperature drops that could lead to frozen pipes. Open Under-Sink Cabinets: On particularly cold nights, open the cabinet doors beneath sinks, especially in kitchens and bathrooms that are located against exterior walls. This allows warmer air from the room to circulate around the pipes, lowering the risk of freezing. Drip Your Faucets: In areas prone to freezing, allowing a slight drip from a faucet can help keep the water flowing through the pipes, reducing the likelihood of freezing. Seal Cracks Around Windows and Doors: Cold air can infiltrate through gaps and cracks, chilling your living space and plumbing. Sealing these openings helps maintain a stable indoor temperature and relieves pressure on your HVAC system. Steps to Take if Your Pipes Freeze If you suspect your pipes have frozen, stay calm and take the following actions: Shut Off the Water Supply: If you notice reduced water pressure or strange sounds, immediately turn off the main water supply to prevent further damage. Apply Heat with Care: Use a hairdryer or space heater to gently warm the frozen pipes. Start from the faucet and gradually move toward the frozen section. Contact a Professional: If you’re unable to safely thaw pipes or observe any cracks, it’s wise to call a professional plumber or HVAC technician, if the frozen area if affecting your HVAC system, right away. They can diagnose the issue and ensure your system is back in working order. B. Dumont Heating and Air is here to help you with any heating related issues this winter!
