How to Choose Furnaces
BTU Ratings
BTU, or British Thermal Unit, measures heating power. A higher BTU rating means more heat. For an average-sized room, a furnace should have 30-60 BTUs per square foot. Calculate your room size to find the right BTU rating.
Efficiency Ratings
Look for furnaces with AFUE ratings above 90%. AFUE, or Annual Fuel Utilization Efficiency, measures how much energy is turned into heat. Higher ratings mean lower energy bills. Aim for at least 90% for best efficiency.
Installation Type
Furnaces can be upflow, downflow, or horizontal. Confirm the type that fits in your home. Upflow units blow air upwards, while downflow ones push air down. Ensure the chosen model matches your home’s layout.
Noise Levels
Check the decibel (dB) ratings. Quiet models operate under 60 dB. If noise is a concern, look for multi-speed motors that operate more quietly at lower settings. This will ensure comfort in your home.
Warranty Terms
Warranties vary widely. Generally, a good furnace should offer at least a 10-year parts warranty. This protects you against defects and failures. Always register your furnace after installation to activate the warranty.
What to look for
Energy Efficiency
Energy efficiency is critical when choosing a furnace. Look for models with AFUE ratings of 90% or higher. A more efficient furnace uses less fuel, which lowers energy costs. This can lead to significant savings over time.
Heating Capacity
The heating capacity of a furnace is measured in BTUs. Calculate your heating needs based on the size of your home. Larger homes require models with higher BTU ratings. Ensure the furnace can heat your space effectively.
Furnace Type
Furnaces come in various types, including gas, electric, and propane. Gas furnaces are often more efficient and cheaper to operate, while electric models can be easier to install. Choose based on your home’s infrastructure and fuel availability.
Maintenance Requirements
Regular maintenance is essential for the longevity of any furnace. Check if the model requires annual servicing. Some units may need filter changes or inspections more frequently. Consider ease of maintenance when selecting a furnace.
Installation Complexity
Installation can vary in complexity. Some units are easier to install than others. If you are not a DIY person, look for models that come with professional installation options. This can save you time and effort.
Frequently asked questions
What are furnace reviews?
Furnace reviews provide insights into different models, efficiency ratings, and user experiences. They help you compare features and make informed decisions.
How do I know what size furnace I need?
Calculate the BTU rating needed for your space. Usually, you’ll need about 30-60 BTUs per square foot of living area.
Are high-efficiency furnaces worth it?
Yes, high-efficiency furnaces save you money on energy bills over time. They often have AFUE ratings of 90% or higher.
How long do furnaces typically last?
Most furnaces last between 15 to 30 years, depending on maintenance and usage. Regular servicing can extend their lifespan.
What maintenance do furnaces need?
Furnaces require regular filter changes, annual inspections, and cleaning. Keeping them maintained ensures efficient operation and longevity.
