"Robert did a great job in checking out my furnace that wasn't operating and provided me with the next steps I needed to take with the gas company. I can't say enough good things about Robert. He was so extremely helpful and informative. I'm a delighted customer and am glad I have Dunn for my heating and cooling needs."

"After telling their phone person the make, model, the fact that it had a large compressor on the top unit; and that my husband had run diagnostics, I worked from home to wait for the repair person. He arrived - and before I could tell him what was wrong, he said he couldn't work on it, they sent the wrong guy out. That he didn't work on built-ins. So he arranged the guy that *does* work on built-ins to come out the next day. The "built-in" repair person came the next day, only to tell me *he* couldn't work on it because my husband had vacuumed and recharged the system. He was very apologetic and nice, didn't charge for a service visit, and recommended another company. If they had a competent phone person that had at the minimum wrote down the information I had given, and relayed that to the repairmen, I would have saved myself two days of my time and could have gotten my repair done more quickly."

"I was having an issue with my AC unit, called Hively heating and cooling after reading great reviews on Thumbtack. John got back to me within the hour and came to my home that evening to try to repair a very old unit. I chose a whole new system and it was installed two nights later. I would highly recommend, John was extremely professional as was his crew, He kept me well informed every step of the way. Great job!!"

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.
