"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."

"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!"

"I hired Aaron to diagnose and repair my frozen air conditioning unit. He arrived on time and was excited to explain everything he was doing while I watched. He started with very basic troubleshooting and progressed to more advanced diagnostics before coming to a conclusion. There was no stone left unturned as he looked into the issue I was having. Once he diagnosed the problem and determined there were no leaks, he quickly repaired the unit back to factory specifications. Aaron provided high quality work, honesty, reasonable rates, and a great personality. I will gladly be hiring him to service and repair my A/C and furnace in the future. I highly recommend Four Seasons Heating and Cooling for anyone needing heat/cooling installs and repairs."

"Robert is A.MAY.ZING! I purchased a 1932 log cabin that needed a LOT of work. I hired Robert to install a force-air heat system. He had to completely create the ducting under the house AND he built out a utility room for me where he installed the furnace/A.C., tankless water heater, and a stacked washer & dryer. The room is beautiful with a pocket door and he matched the tongue and groove knotty pine walls. The 1932 original river rock fireplace and huge chimney was in bad shape, so I decided to change to a propane insert. Robert took out the old chimney, re-roofed the area, reinforced the base under the house, preserved the river rock and installed a perfect insert. Originally the chimney was on the outside of the house but somewhere along the line, someone added more rooms around the chimney. By removing that, Robert created more room in the kitchen and bathroom. He remodeled the bathroom and kept the integrity of the vintage kitchen. He installed an automatic sump-pump under the house as well as reinforced the supporting beams and installed strapping for earthquake support. His pricing is good and communication is great. He takes photos as he works to document the progress. He was clean and organized. I would absolutely hire Robert and Ozanne Custom again and would definitely recommend him to others. He is also well connected in the construction field and was able to tell me names for other people to hire for other jobs. Thank you, Robert!"

"We had many issues with our computer - primarily with the CD/DVD drive and iTunes. Jim eliminated over 700 viruses from our computer, which was just the beginning. There continued to be problems within the systems of the computer. Luckily Jim charges by the job and not by the hour because he worked a LONG time to make it all work.  He kept in touch with me and addressed each issue as it arose until the job was done.  He was professional and courteous and hung in there until I was satisfied he had addressed everything. I would highly recommend Jim and will definitely use his services in the future, as needed.

"Sears was a great company to work with, but they contract out, so make sure you check out who they hire for your project. At first, Shannon Heights Heating & Cooling came, but they were TERRIBLE!! They were no-shows twice, and were 2 hours late the day of installation, so we asked for someone else. Sears was great and got someone else right away, but it was definitely discouraging that they didn't check out who they contract out to better."

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