"I was very impressed with the knowledge and professionalism of the Ranger team — beginning with Dan who provided options and information so that we could make an informed decision, to the installation teams led by Matt and Scott. Everyone was very respectful and explained each step of the process. Before they left, they made sure to leave everthing as they found it, including my challenging gate. I would highly recommend Ranger Heating & Cooling."

Best of all, they got my system back up and running without the costly replacement of my heat pump. Their honesty and expertise have earned my trust, and when the time comes for any future HVAC work, they’ll be my first and only call. Highly recommend!"

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"They worked with me to determine a very reasonable solution to a difficult water / heating problem I had in my crawlspace. They replaced all the flex heating ducts and insulated all of the rigid ductwork making routing updates to help ensure they all stayed dry in the future. Their estimate was fair and accurate, they completed the work on time and the quality of the work was excellent. All of the workers were very professional and respectful and they ensured that I was completely satisfied at the end."

"Bronze is amazing, heâ s hard working, thorough, and honest, and was the best bid for installing a new Heat Pump for our house. He was great at helping us to figure out what Heat Pump would work best for our particular home, since there was no Heat Pump installed yet. His work is clean, and his personality is very professional. His quality of his work is top notch!! He was very responsive in answering all of our questions, and in offering suggestions to make sure we would be happy with the end product. We highly recommend Bronze - he does wonderful work!!!"

FAQs for furnace / forced air heating system install or replace projects in Vashon, WA

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.
