New HVAC for an Old House

September 12, 2024

Old houses have an undeniable charm and appeal, but they often come with their own set of challenges. When considering purchasing an older home, one crucial factor to take into account is the condition of its heating, ventilation, and air conditioning (HVAC) system. In this blog, we'll explore the considerations for adding a new HVAC system to an old house, inspecting an existing HVAC system, and what to look for when considering an upgrade.


Assessing an Old House for HVAC Installation

Old houses may present several challenges when it comes to the efficiency of a new HVAC system. Here are some key considerations:


Air Leaks and Insulation 

Old houses are prone to air leaks due to gaps and cracks resulting from the natural settling of the structure. Proper sealing and insulation are essential to ensure the efficient operation of an HVAC system.


House Design

The design of an old house, such as high ceilings or crawl spaces, can make it challenging to heat and cool effectively. Additionally, some houses may have limited space for ductwork installation. This is something to note and to contact a professional about to see if there would be sufficient space for duct installation.



Ductwork

While some old houses may already have ductwork, others may lack the necessary infrastructure for traditional HVAC systems. Consulting with a professional is essential to determine the feasibility of installing ductwork in your home.


Existing HVAC Systems in Old Houses

If your old house already has an HVAC system in place, here are some factors to consider:


System Condition

Assess the condition and age of the existing HVAC system. An older system may be less efficient, require more frequent repairs, and result in higher energy bills. If the system is almost 15 years or older it may be time for an update.


Ductwork Quality

Inspect the ductwork for air leaks, mold, or mildew growth, which can impede the system's performance.


Energy Efficiency

Check the Seasonal Energy Efficiency Ratio (SEER) rating of the system and its insulation quality to gauge its energy efficiency.



Installing a New HVAC System

When considering installing a new HVAC system in an old house, here's what you need to keep in mind:


Sealing and Insulation

Prioritize sealing air leaks and improving insulation to create an optimal environment for the new HVAC system.


Unit Selection

Choose an HVAC unit or mini-split system that is suitable for the size and layout of your home.


Ductwork Considerations

Determine if your house has sufficient space and layout for ductwork installation, and consider alternative options if traditional ductwork is not feasible.




Ensuring the comfort and efficiency of an old house's HVAC system requires careful assessment and planning. Whether you are considering installing a new HVAC system or evaluating an existing one, professional expertise is invaluable in making informed decisions.

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!
