"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"Our Greenwood Technician, Sam, really provides us assurance that our gas furnace is still functioning adequately, but detailed why it may be time to consider replacing our aging water heater and furnace water pump system before likely damage occurs. Sam is a most genuine and reassuring professional - He helps us know just what may need maintenance and what is still sound. It is a joy to work with a trustworthy and competent professional"

"Great. I wanted to replace my oil furnace with a system that does both heating and cooling. They came by, did measurements, and presented some options. I chose the Mitsubishi mini split system because I have a large house and don't need to heat or cool all of it all the time. They installed in a day. Very easy, very boring, I also had them replace the water heater."

"Allred is THE best. I had mini-split AC/heat installed almost a year ago. I love it and it's saving me significant money over using my central heating system. And no more hassle with portable air conditioners. I should have done this years ago. Even better is the 5 star customer service. Last week I had difficulty turning on the AC for the first time since last summer. I urgently called David on a Sunday. He immediately dove in to get me scheduled. Sebastian called me before making an on-site visit. Patiently walked me through a simple troubleshoot and shazaam! I turned right on. A+++ to both of them."

"This company has been consistently good for me and my house in the last 11 years. Having to deal with changing a furnace, a water heater, and last week a heat pump , is not for the faint of heart. I have to say, John and Debbie made it relatively painless. They worked on my timetable and were very accommodating. Most of the technicians that installed my furnace 11 years ago are still there. Those guys are fast and efficient. AND they clean up after themselves! Which is something I can't say about the electrician, the roof people, the window replacement guys I've had to deal with. I never write reviews (unless I am mad beyond reason:), but for Bassett - thank you guys for being so easy on my nervous system!"

"This was an excellent customer service experience. I selected Day & Nite Plumbing & Heating in Lynnwood, WA on the strength of Angie's List reviews that describe actual furnace repair work rather than other companies that seem more focused on doing furnace replacements. (Day & Nite do replacements, of course, but the reviews cited a fair number of repairs as well.) Although my gas furnace (a Carrier Weathermaster 800) is about 20 years old, my circumstances didn't allow replacement. When I contacted Shondra in their office about available appointments they were booking several days out, but were able to move it up a day and a half which was very appreciated given the cold nights. Tyler was the HVAC-R Technician sent for my appointment and he was amazing - both personable and knowledgeable, he listened to my concerns and quickly diagnosed and fixed the unit. He also understood that I am someone who likes to know details on what is being done and why – not too much detail, but enough so I felt informed which reassured me. Tyler’s great customer service and positive attitude, on top of his knowledge and experience with the technology impressed me so much I signed up with Day & Nite for their annual furnace maintenance plan next winter and will happily refer my friends and family for their furnace needs. I have yet to experience the Day & Nite plumbing services, but on the strength of my experience with Day and Nite and support by Tyler, I will give them a call when that need arises. (FYI: The approximate service cost of $600 included the ignitor part less a 10% customer discount for signing up for the maintenance plan, the trip charge and that for next winter’s maintenance trip, plus tax.)"

FAQs for furnace / forced air heating system install or replace projects in Seattle, 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.
