Benefits of an Attic Furnace
Looking for an excuse to install an attic furnace? We’ve got five great reasons why this might be the perfect heating solution for your home.
Quieter Operation
One of the primary benefits of an attic furnace is its quieter operation. Placing the furnace in the attic isolates the noise from the living spaces, creating a more peaceful and enjoyable living environment. No more disruptive hums or vibrations echoing through your home—just cozy warmth without the unwanted sound effects.
Easy Installation
Attic furnace installation is relatively straightforward compared to other heating system setups. It doesn't involve major modifications to your existing living spaces, reducing the disruption to your daily life. Professional HVAC technicians can efficiently install the unit, ensuring a seamless transition to a heating solution that works for your home.
Saves Space
A common woe in many homes is the constant battle for space. Attic furnaces address this concern by taking advantage of the often-underutilized attic area. This creative use of space can free up closets, garages, or other living areas that a furnace typically lives in, providing you with more storage or living space options in your home.
Less Duct Work, Lower Cost
Installing an attic furnace can be cost-effective in terms of ductwork. Since the furnace is placed overhead, there's less need for extensive ductwork throughout the house. This can result in lower furnace installation costs.
Flood Damage Risk Nearly Eliminated
Basement furnaces are susceptible to water damage in regions prone to heavy rains or flooding. By moving the furnace to the attic, you nearly eliminate this risk, ensuring that your heating system remains functional even during adverse weather conditions. Now you just need to make sure there are no leaks in your roof or attic skylight that could let water in!
Drawbacks of an Attic Furnace
As with most projects, and especially those concerning HVAC systems, installing an attic furnace comes with some downsides that might deter you from the project.
Lower Furnace Efficiency
Attic temperatures can vary significantly from the controlled environment of your home's living spaces. Extreme heat or cold in the attic can affect the efficiency of the furnace, leading to higher energy consumption and potential strain on the system.
Less Opportunity to Discover Issues
Having your furnace tucked away in the attic is great for space-saving, but it can make it less accessible for regular visual and audible checks. This reduced visibility might lead to furnace issues going unnoticed until they become more serious problems, potentially leading to high furnace repair costs or replacement.
More Duct Openings in Your Ceiling
Attic furnace installation involves additional ductwork running through your ceilings. While this helps distribute heat effectively, it also means more openings in your ceiling that might require repair, painting, or maintenance.
Possibly More Damage to Ducts
Extreme temperatures in the attic can potentially damage duct materials over time. This could lead to leaks, reduced efficiency, and more expensive air duct replacement costs or repairs.
Potential Fire Hazard
Placing a heat-generating device, like a furnace, in the attic comes with at least some inherent risk. And attics are full of things that fires love to eat, like wood and insulation. Luckily, professional HVAC installers know how to install an attic furnace safely, decreasing the fire risk almost entirely. The fire risk is why it’s so important NOT to DIY this job if you want an attic furnace.
When to Consider a Furnace in the Attic
Not sure if this is the best solution for you? Here are some times when getting an attic furnace might be the right call.
You’re Building Another Story or Addition
If you're planning to add another story or an addition to your home, adding a second furnace in the attic becomes a practical choice. It ensures consistent heating for the new space without overburdening the existing heating system.
You Don’t Have a Basement
Homes without a basement can benefit from attic furnaces. This heating solution frees up space in living areas or closets that would otherwise house a traditional furnace. This makes your home more functional and comfortable.
You Live in a Smaller Home
Similarly, in smaller homes, reduced space and noise from the furnace can be more noticeable. An attic furnace offers a quieter alternative that doesn't disturb you or occupy your living space.
Things to Consider When Putting a Furnace in Your Attic
Choose a high-efficiency furnace: This is essential to mitigate potential temperature-related efficiency losses in the attic. A high-efficiency furnace can adapt to varying conditions, ensuring optimal performance.
Plan to clean and inspect your furnace regularly: Regular maintenance is key to prolonging the life and efficiency of your attic furnace. Schedule periodic cleaning and inspections to identify and address issues promptly.
Schedule regular preventative maintenance: Consider enrolling in a preventative maintenance program with a trusted HVAC service provider. This proactive approach can catch problems early and keep your attic furnace in top condition.
DIY vs. Hiring a Pro
While DIY enthusiasts might be tempted to install an attic furnace themselves, it's a task that's best left to professionals. Local furnace installers have the expertise to ensure a safe and successful installation, minimizing the risk of safety hazards or mistakes that could lead to a less efficient HVAC system down the road.
Frequently Asked Questions
Reinforcing your attic floor is a crucial consideration when installing a furnace. Attic furnaces come with a certain weight that needs to be supported by the structural integrity of your attic floor. Without proper reinforcement, you risk sagging, cracking, or even structural damage over time. Before proceeding with an attic furnace installation, consult with a structural engineer or a qualified HVAC technician who can assess the load-bearing capacity of your attic floor and recommend any necessary reinforcements.
Attics often contain a mix of insulation, electrical wiring, and other materials that can pose fire risks. That’s why furnaces should be installed in the attic with proper insulation and clearance from combustible materials. Additionally, the furnace should be equipped with proper ventilation and heat shields to prevent the buildup of excessive heat in the attic space. Regular inspections and maintenance are also crucial to identify and address any potential fire hazards.
Attic furnaces can require slightly more maintenance than their basement counterparts. The attic environment can subject the furnace to a wider range of temperatures and humidity levels, which can impact its performance over time. These temperature fluctuations can lead to more strain on the system and potentially accelerate wear and tear. It's recommended to schedule periodic inspections and cleanings to ensure that the furnace is functioning optimally. Attic furnaces might require more frequent air filter changes, especially if they're exposed to dust and insulation particles that are common in attics.
