"Milo is a skilled, professional heating and air conditioning journeyman technician and has been in the trade for eight years. I was surprised to learn that he is also a skilled wood craftsman. So in addition to maintaining my furnace system he refinished my teak dining room table and repaired a broken table leg. He works efficiently for furnace or wood repair."

"In the beginning the 4 nations of Electric, Plumbing, Heating, and Air lived in harmony. Because Seatown maintained the balance. We have used Seatown for 15 projects now for spanning all their services. When we bought our old home, we had Seatown and other competitors provide quotes on installing HVAC. Their planning, thoughtfulness to our needs, price is why we chose them. As the summer heat spikes, we don’t regret our choice and are glad that our home is an oasis. Every time they come out, we ask for more things to be done than what was agreed to and every time they work to extra hard to get it all done. They go the extra mile in doing some simple projects for free and giving advice on how to lower our costs as new homeowners. I have been able to call or text them about issues or ideas and get advice with out the pressure to buy services. That’s not something you find in just any company. Their staff has always been polite, clean, and diligent about getting the job right the first time. As we continue to fix up our old house, we will be using Seatown for projects large and small and we hope you will as well."

"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."

"I appreciated that the company rep did a wonderful job explaining the workings of a heat pump. His explanation made it easy for me to decide to change to a heat pump from my tried and true (and old) gas wall heater. I appreciate the installers, the electricians, and the followup by the company rep after the installation. Love my quiet warm air! I highly recommend West Mechanical!"

"We'd used them four years ago to replace our windows. They were about 40% the cost of Renewal By Andersen for the same Andersen windows, were professional and courteous throughout the process, and we haven't had a single problem since. So when we wanted to put in a heat pump system for efficient heating and cooling they were high on our list. We got four bids, and once again they were the least expensive, in this case by a 30% margin. They explained our options well, came up with some creative solutions (we're an old house with old vent-work which they bypassed for the ductless pumps but used for a top quality air filter), and did the job quickly and efficiently. They've checked back a couple of times since to make sure everything is ok, which it is, and it's been really nice to heat our bedroom on some cold nights and cool my western facing home office on some sunny afternoons). When the permit inspector asked before they came over who our installer is and I told them, they said "They do really good work." Definitely recommend them to others and in fact already have."

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