"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

"**5 Stars — Small Business to the Rescue!** Brian and Valerie of Chatfields LLC AC and Heating saved the day! Our furnace failed while guests were staying at our property. A larger HVAC company quoted $2,150 to replace the circuit board and two pressure switches. Thankfully, we sought a second opinion. Brian carefully investigated, confirmed the board and one switch were working, and replaced only the faulty pressure switch. Heat was restored the same day for $275—a $1,875 difference! Beyond the savings, Brian was thorough, honest, professional, and true to his word. Meeting his wife, Valerie, was equally wonderful. They are such a kind, warm couple who made a stressful day easier. This is why I love supporting small businesses! Chatfields stepped in where a larger company fell short and earned my trust and future business. I'll gladly continue supporting hardworking small businesses like theirs. Thank you both for your integrity and outstanding service. Highly recommended!"

FAQs for furnace / forced air heating system install or replace projects in Castle Rock, 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.
