"Even though I have solar heat, my electric bill was around $300 per month for four or more months. I have two furnaces and heat pumps. Temperature control cleaned the ducts (that had never been cleaned before) and found there was a 25 and 35 percent leakage. They sealed the ducts. It was at a time when I was getting ready to turn the heat off.. I've had two electric bills since. One was $70 and the latest was $60. The airconditioning in the house is very even and comfortable, not like the previous year. It will be interesting to see what my winter bills are. I expect they will be normal."

"Nate was extremely professional and thorough throughout the whole in-home estimate. Within the time he was he did a walk around our home to explain the AC installation options, inspected and explained the electrical work after verifying our home was capable to handle the AC. Nate was detailed while explaining all the available financing options and worked with us to ensure the best pricing available. It was definitely a pleasure to work with Nate on this project. Many thanks to Nate and Dynamic Comfort."

"I love that I can trust them not to up sell me. When other companies were trying to sell me a heat pump, Eric was able to install an AC and furnace for about half the price. There were no hidden fees either. I paid exactly what I was quoted. The installation was easy and so quick it didnâ t even get hot inside before my new unit was up and running. This is a quality company that cares about people. I highly recommend them."

It is refreshing to see a company that puts so much effort into ensuring their work is done right the first time. They don’t just treat you like a customer, but a partner in the process. The attention to detail, transparency in pricing & personalized care made us feel like we were in good hands every step of the way. I high recommend Top Care Air"
Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.
Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.
With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.
The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.
Consulting with an HVAC professional can help you determine the exact size that's right for your home.
An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.
An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
