How do I Choose Between an Electric vs. Gas Furnace?

October 31, 2024

Just can’t seem to get your home warm enough in cooler temperatures? Well, it may be time to upgrade your heating system! Yet, with so many different types of systems to choose from, how do you know which one is right for you? Custom Cooling & Heating is here to help you navigate that decision-making process. So, let’s talk about furnaces. In this blog, we’ll answer the question “How do I choose between an electric vs. gas furnace?” 


1. Efficiency and Operating Costs 

Electric furnaces are known for their 100% efficiency (buy $1 of electricity and get $1 worth of heat) and typical lower installation costs compared to gas furnaces. They don't need a flue or vent, so that makes the installation process easier and less expensive than gas furnaces. The downside to electric furnaces is that they can be more costly in the long run to operate in areas with higher electricity rates and sometimes the home doesn’t have the adequate electrical panel size or space for the electric furnace. 


On the other hand, gas furnaces typically have lower operating costs, especially in areas where natural gas is readily available and fairly affordable. The initial investment may be higher, but the long-term savings on energy bills can definitely offset those costs, especially if you chose a 96% - 97%  efficiency gas or propane furnace. 


2. Performance and Comfort 

Gas furnaces are known for their incredible heating abilities. They can warm up spaces of any size and any temperature, getting the job done quickly and efficiently. They provide consistent heat, which can be especially comforting in colder climates.  All new models have a high efficiency blower and many have 2-stage or multi-stage heating capability. 


Electric furnaces may be efficient, but they might struggle to keep up with that same level of heating performance as gas furnaces, particularly in extreme cold conditions. Electric furnaces are typically coupled with heat pumps allowing them to only needed during colder temperatures.  Electric furnaces typically have a louder blower noise due to their design. 


3. Environmental Impact & Sustainability 

Electric furnaces produce zero emissions while in use, making them a cleaner and more environmentally friendly option. Electric furnaces are considered a more sustainable choice, bonus points if they’re powered by renewable energy sources like solar or wind.  Keep in mind a lot of our electrical energy in the midwest comes from either coal fired or natural gas power plants. 


While gas furnaces are efficient, they do produce emissions during combustion, contributing to air pollution and greenhouse gas emissions. Luckily, modern technology allows for more environmentally friendly options with lower emissions.  There is not a lot of wasted energy in the combustion process of a 95% or 97% furnace. 


4. Installation and Maintenance 

Electric furnaces are typically easier to install and require less maintenance than gas furnaces. Because they don't require a flue or chimney, there are no concerns about carbon monoxide leaks or gas line connections.  Electric furnaces still need maintenance but there are less components internally to fail than a typical gas furnace. 



Gas furnaces require proper venting and combustion air supply, which might require additional installation considerations. They also need regular maintenance, including annual inspections and cleaning of the burner and flue. 


Making the Right Choice 

Choosing between an electric and gas furnace ultimately depends on what your specific needs, budget, and priorities are. If you’re looking for energy efficiency and environmental sustainability, an electric furnace may be the way to go. But if heating capabilities and lower operating costs fit your needs better, a gas furnace may be the better choice for you.

The Benefits of Home Zoning Systems

April 25, 2025
Achieving the perfect indoor climate in every room of your home can be a challenge, especially when different family members have varying temperature preferences. If you find yourself constantly adjusting the thermostat to accommodate different areas of your home, a home zoning system could be the solution you need. At Custom Cooling & Heating, we specialize in innovative HVAC solutions , including home zoning systems, to provide enhanced comfort, energy efficiency, and cost savings. What is a Home Zoning System? A home zoning system divides your house into multiple climate-controlled areas, allowing you to set different temperatures for each zone. This system utilizes dampers within the ductwork and individual thermostats for each zone, giving you precise control over your home’s heating and cooling. Whether you want to cool the upstairs bedrooms while keeping the downstairs warmer, or adjust temperatures based on room usage, a zoning system makes it possible. Due to each home having a different duct design, Custom Cooling & Heating, INC will perform an onsite evaluation of the duct system and offer specific solutions for your system. Key Benefits of Home Zoning Systems 1. Enhanced Comfort for Every Room Traditional HVAC systems often create temperature inconsistencies, making some areas too hot or too cold. Zoning systems allow for customized climate control, ensuring every room stays at a comfortable temperature for its occupants. 2. Increased Energy Efficiency With a home zoning system, you can direct heating and cooling only where it’s needed, reducing energy waste. By not conditioning unoccupied areas, your HVAC system operates more efficiently, leading to lower energy consumption. 3. Lower Utility Bills By using energy more effectively, a zoning system can significantly cut down your monthly heating and cooling costs. According to the U.S. Department of Energy , homeowners can save up to 30% on energy bills with a properly installed zoning system. 4. Prolonged HVAC System Lifespan A traditional HVAC system works harder to maintain a uniform temperature throughout the entire home, leading to more wear and tear. A zoning system reduces strain on your HVAC unit, helping to extend its lifespan and reduce the need for frequent repairs. 5. Personalized Temperature Control Each zone in your home will have its own thermostat, allowing family members to set their preferred temperatures in different areas. This eliminates thermostat battles and ensures comfort for everyone. 6. Ideal for Multi-Story Homes & Large Spaces Homes with multiple floors often experience temperature imbalances. A zoning system helps regulate temperatures more effectively, keeping upper floors from getting too warm in the summer or too cold in the winter. Is a Home Zoning System Right for You? A home zoning system is ideal for homeowners who: Live in a 2-story home and are not comfortable on the 2nd floor Have rooms that are rarely used and don’t need constant heating or cooling. Experience noticeable temperature differences between floors or rooms. Want to reduce energy waste and lower their utility bills. Have family members with different temperature preferences.
