"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!"

"It was an outstanding experience from start to finish. The floor sanders left my heat pump running while sanding. I replaced my duct filters three days in a row because they were filled with dust and debris. I needed help in a hurry, and Keith went out of his way to make it happen so my painters could arrive on time. I also had electrical work happening on the same day so the power was turned off. Keith went above and beyond to find a portable generator and complete the work. It was an all day job in the heat, and Keith got it done. My vent filters have been sparkling clean for the five days since he did the work. I highly recommend this company."

"I was having ongoing problems with my furnace, and Keith Tilley and his crew worked on it several times until I finally realized it was time to replace it. Keith never pushed me to make that decision but was able to help me when I was ready. We set a date for the work to be done, which I changed at least twice, and I also asked him to look into a specific type of furnace that had been recommended to me. Keith told me what he found out about that particular unit but didn't recommend it even though it was more expensive. The gentleman who did the installation was on time the day the installation was scheduled. He completed the work in a reasonable amount of time, answered my questions, and showed me the things I needed to know about the new unit. He cleaned up his work area once he was done and took the old unit away. Not long after the work had begun, Keith called me to be sure everything was going well, and the man doing the work called Keith to ask him a question about the thermostat. I appreciated the fact that even though Keith wasn't doing the actual work, he took the time to check on things; I also liked the fact that when the man doing the work, I'm sorry I don't remember his name, had questions about the thermostat, he called Keith instead of trying to figure it out on his own, which could possibly have made the problem worse. All in all, this was a very positive experience, and I will continue to use Tilley Heating and Cooling.

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.
