"Excellent! Tim was early/on-time. He spent time explaining my equipment and options. He didn't try to "up sell" and "over sell" me on anything. He was straight forward and told me the reality of what my options we're in the future because my furnace has another good 5+ years left in it! Refreshing experience with Emporia Home Services. I recommend them to everyone."

"Late on a Friday night my furnace stopped working. I called Dale and he walked me through the furnace and diagnosed my problem over the phone. He was spot on with the diagnosis, and I got a new fuse and the furnace started working again. Dale is very professional and wants to help."

"We called Jason on a Sunday evening when our AC was out. He came over in less than a hour and went right to work troubleshooting the system. There had been multiple failures, but he tracked down the issues and had the necessary parts. He clearly enjoys his works and he’s a tenacious problem solver. Highly recommend him!"

FAQs for furnace / forced air heating system install or replace projects in Denver, CO

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.
