"My experience with Greenwood Heating and Air Conditioning has been entirely positive. From my free estimate appointment through finished installation, the process was seamless. Each and every representative of theirs has been exceptional. Trevor negotiated a very competitive, all inclusive price for the entire system and followed up on the day of installation to see how everything was going. The install was expertly performed by an industry pro, Andril, with 17 years plus experience. Follow-up has been exceptional. Greenwood Heating has earned my unequivocal recommendation."

"The entire process went very smooth. From the initial call to final install, everyone was pleasant to work with. The Comfort Advisor, Scott, put my mind at ease with all my questions and concerns. I got the quote shortly after the assessment, accepted and was scheduled for install very quickly after. The install team was very communicative during the process. They all came in and worked together to get the job done in a short amount of time and left the area looking better than when they arrived. Everything has been working great and I couldn't be happier with my heat pump. I would not hesitate to recommend them to anyone I know."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"I got prompt service when I called to have my furnace serviced & to inquire about completing installation of air conditioning. I found out my electrostatic filters were not working, so I will use disposable air filters until I need to replace my furnace. At that time, I will probably go with a heat pump system. Eli is a very nice young man who explained everything to us to help us make decisions regarding our heat and air filtering system. Would hire again!"

"From first contact with an estimate (Rich), Cummings, Inc. was great to work with. Their crew (Blake, Nick) was highly skilled, hard working and exceptionally professional as they performed their work. Blake and Nick returned a couple of days later to check in with us, provide additional filters, make sure system was working correctly and ensure we understood thermostat functions. Cummings was very reasonable in their quote for work completed. We would highly recommend them for a furnace/heat pump replacement."

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.
