"Indoor Air Man and Energy Conservation Specialist once again did a fabulous job for me. Yesterday, Danny reconnected my heating and Ac duct work in the renewed cellar and under my house. He also put back the ceiling vent covers. Danny once again exceeded my expectation and he is one of the most polite and pleasant serviceman I have had work in here. A few years ago, Indoor Airman previously did a performance assessment of my home for free. The they renewed my heating and Ac duct work and the cellar was not accessible at that time (TAX Credit). They also put insulation in my attic plus a solar attic vent fan for which I got another (Tax Credit). When I heard strange noises in my attic, they placed traps on my attic and under the house, catching 5 rats! Danny even came back and took out the caught rats. Danny fixed my crawl space with a nice cover. They are my go to guys for so much of my home needs - Their diverse skills and work are much appreciated. Thank you, Danny! You do a superior job, it is a pleasure doing business with you and to INDOOR AIRMAN."

"Allied Comfort Pro has outstanding customer service. We had two other companies out for a service call and they could not diagnose the issue. We were recommended to call Allied and their service tech came out and not only found the issue with our HP but also informed us about their Maintenance service plan. The technician was very knowledgeable and took the time to explain how our system operates. We highly recommend this company."

"I was having a problem with MS Office not responding and other files being very, very slow to open. Jim started looking for the cause right away. He did numerous checks for viruses, malware, and various other things that can go wrong. He vigorously pursued a resolution pretty steadily for two days before determining it was a malfunctioning external backup system that was causing the problem. With that finding, he promptly got my computer running smoothly and very fast again. He made two trips to my house; on the first one, he had to cross a sheet of ice in my driveway. Jim is a very capable and experienced computer analyst that will get after your problem because he fully understands the importance of, and the need to have a working computer in the house.

"We chose them because they had a lot of good reviews on Angie's List. We were more than satisfied with their service. They respected our household and they worked very clean. They didn't leave any of their work materials in our way when they left. They put cardboard on the floor when they were sawing the drywall to put in the vents. Everything they did had a real consideration for our household. They were as unintrusive as possible. They really had a lot of fine details that were very pleasant that we wouldn't have even thought to look for. We contacted them during a busy time of year for air conditioning systems. We tried about 5 companies and they were the only ones that called us back. They scheduled us right away. We would recommend them because they find a way to get things scheduled during the busy season."

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