"Wayne was the absolute best, we called on a Saturday during an unexpected cold snap and he came right out to assess our heat pump. He got the heat pump back and running. He offered us two alternative heat sources which we did not have. We chose the installation of dual fuel system and we could not be happier. The new system is so efficient (propane furnace) and our existing heat pump. The heat pump is running better than when it was installed. When temperature drops outside our propane furnace kicks in, when it is a higher temp our heat pump runs. It is effortless and efficient solution. If you need a professional call Wayne."

"Anthony and Kaitlyn were amazing! They both went over and beyond helping me with my warranty co. Witch I had been dealing with for 4 mouths. They got things done. Not only did they help with the warranty co they went over all my options, cost and time frames. Worked around my schedule. Showed and explained to me in detail what was wrong with my 2 units. Showed up for appointments. What a blessing! I cant even begin to tell you how how much I appreciated all the extra effort. Both Anthony and Kaitlyn (put in hrs.) dealing with my warranty co. And that no joke! I would highly recommend Honest AC to everyone and they are extremely knowledgeable, honest and affordable. They make it real clear in all that they do! THERE CUSTOMERS MATTER. Unlike my warranty co. LOL Honest ac will have me as a customer for life! Wish you the best success to you both. Thank you! thank you! Anthony and Kaitlyn for your help I needed it."

"CM Walter installed a mini split AC/heat system and did an excellent job. He was professional, considerate of the space, he left everything clean, and the cost was very reasonable. I’m happy with the job he did and highly recommend using his services."
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.
