"Dave Whispell (Project Mgr) and Ivan (installer) did a great job for me. They installed a full house Heat Pump system, along with all ducting to my new addition building, new gas lines and a new premium whole house tankless water heater along with all the electrical and venting. Their knowledge and expertise and financing flexibility was 1st class! Their follow up customer care was Gold Standard. I was so pleased with their 1st & 2nd job, I gave them a 3rd job for a 12K Mini Split heat pump on my ADU. They use top brands products backed by 10 & 12 year warranties and very honest service. They were amazing to work with after so many headaches with other contractors on other jobs. All jobs passed on 1st inspections. Highly recommended!"

"Our furnace started shooting out cold air very early morning in the midst of winter. Evergreen responded first thing the following morning (my request for repair was put in about 4am) and was the ONLY company of 4 requests to respond. They were able to get a technician out the same day for emergency repair. Todd arrived within 2 hours of confirming the visit. The company even sent a text with an image of the technician for safety purposes (this is extremely rare). He was able to diagnose the issue quickly and come up with an affordable fix that would keep the issue from recurring. He had to reroute the drain pipe that had frozen and backed water up into the system … had everything he needed in his truck and was finished within two hours of his arrival and found a solution that was affordable, quick, and professional looking. Before leaving, Todd gave us a mini lesson about the furnace so we can do basic maintenance ourselves in the future. (This is our first home, this furnace was already in place when we bought the house, and we had no experience with these types of systems.) Also gave us some reassurances regarding our natural gas system. I will definitely use this company in the future and would recommend to anyone having furnace issues."

"RK electric is a true jewel of a company. We have worked with them for years, and decided that it was now time to swap out the old, failing lighting in our home, add a couple of circuits for specific purposes, and make sure that our electrical systems were up to current code. RK did beautiful work, helped us find safety-related trouble spots with our wiring, and made time to fix those spots even though the original estimate didn't specify it. The work itself was superb."

"They came on time, found the problem, replaced a motor (which they had in their parts truck) checked the system, and left. Everything works great again and I would definitely recommend them, and will use them again if needed."

FAQs for furnace / forced air heating system install or replace projects in Gaston, OR

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.
