"Follow up service call for a water softener system we had installed 2 weeks ago by Wisler. Ashley did not do the install. She came today to correct an issue found as part of the install. She did a great job. Her knowledge and professionalism were excellent. We appreciate the work she did. My rating on price was not Ashley's fault. It was related to the service contract recently presented to me for Wisler to maintain the system. Apparently the manufacturer has issues with their software which is reflected in price in our contract. It is quite expensive!"

"I noticed in our mail thing that we are due for service on our system to keep our warranty up; to do so we are actually going to do a maintenance contract with them it is about $96 yearly, but they come out and do inspections and everything. The owner is the one who came out and gave us a quote. We had them replace another system which was nor working correctly so the first the thing they did was send someone to inspect the old system to see what were the problems. They fixed it on the spot for free and did not even charge us to come out. They were very nice, courteous and stayed in contact with us the entire time. They were very nice, professional and they got the job done in an efficient manner. They did not charge us an insane amount of money for it. We had a name brand system. It was a well worth investment to have it done right.

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.
