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!

12 Common Heating Problems: Troubleshooting Tips for Homeowners

November 15, 2024
As temperatures drop, ensuring your home heating units are functioning properly is crucial for your comfort and peace of mind. At B. Dumont Heating and Air, we understand that heating issues can be frustrating and inconvenient. That’s why we’ve compiled a list of the most common heating problems homeowners face, along with helpful troubleshooting tips to assist you. If you ever require professional HVAC help, our skilled team is just a call away. 1. Dirty Filter A dirty air filter can severely restrict airflow, leading to overheating or even a complete shutdown of your heating system. To prevent this, make it a habit to clean or replace your air filters every 1-3 months as part of your ac and heating maintenance routine. 2. Dirty Ductwork Over time, ductwork can accumulate dust and debris, which can be dispersed throughout your home when the heating system is in operation. Cleaning your ducts can enhance air quality. You can attempt to clean them yourself with the right knowledge or enlist the help of a professional to ensure the job is done effectively. 3. Pilot Light and Ignition Issues If your home heating units are not producing heat, the pilot light or ignition system may be the culprit. Check to ensure the gas supply is on and that the ignitor is functioning properly. If you’re unsure or if issues persist, seeking professional HVAC help is recommended. 4. Thermostat Malfunction The thermostat is the brain of your heating system. If it malfunctions, your entire system could be affected. Verify that the thermostat is properly set and that the batteries are functioning. If initial troubleshooting doesn’t resolve the issue, it might be time to call a technician. 5. Tripped Breaker or Blown Fuses If your heating system appears to have no power, inspect your breaker box for tripped breakers or blown fuses. This may indicate that your system has been overworked, potentially due to a clogged filter. After replacing the filter, if the issue remains, a professional can provide further diagnostics. 6. Water Leaks from the Unit Condensation can lead to water leaks if the drain lines become clogged. You might be able to clear the lines by pouring a mixture of bleach and water down the drain. For persistent leaks, contact a professional to get the situation resolved. 7. Uneven Room Temperature When some rooms in your home are warmer than others, it may be a sign that your ductwork needs adjusting or that there’s an issue with airflow. A thorough inspection from one of our technicians can help identify the underlying cause. 8. Cool Air Instead of Heat If your heating system is blowing cool air, first check the thermostat settings to ensure it’s set to "auto" instead of "fan." Next, inspect the air filters and pilot light. Should the issue continue, it’s best to reach out to an HVAC professional for assistance. 9. Burning Smell When your heating system is first activated for the season, a slight burning odor can be normal. However, if that smell persists for longer than a couple of hours, it could indicate a clogged air filter or a more serious issue. It’s advisable to turn off your system and call a professional if the smell continues. 10. Frequent or Over Cycling If your heating system frequently turns on and off, examine the thermostat settings. This issue could stem from a thermostat set too high or low or from a dirty filter. If these adjustments don’t resolve the problem, a technician can help identify and fix the issue. 11. Rattling or Pinging Noises Strange noises, like rattling or pinging, can occur due to ductwork expanding or contracting with temperature changes. It might also indicate loose panels that need tightening. If the sounds persist, don’t hesitate to reach out to a professional for an inspection. 12. High Humidity Excessive humidity can cause significant problems, leading to mold growth and damage. This may result from inadequate ventilation or malfunctioning exhaust fans. A qualified HVAC professional can assist you in finding an effective solution. Being aware of these common heating problems can help you troubleshoot issues with your home heating units effectively.
