"Eric (couldn't read last name) called us approximately 30 minutes in advance of his arrival. He performed an annual inspection of my home heating system. He completed the work quickly and cleaned up after himself when finished. Eric was friendly and courteous and answered all of my and my wife's questions completely. He assured us that our heating system was operating properly and explained the checklist he used to do the inspection. It has been functioning without any problems to date. I would recommend Eric and One Hour without reservation."

"Tim Klatt was very communicative, professional, and easy to work with throughout the process. Although the issue with the furnace turned out to be a simple fix, he took the time to explain everything clearly and made sure the system was working properly before leaving. Great customer service and overall experience."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"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."

"you want an honest and fair electric, heating and plumbing company, hire Tuscan and ask for Jim Cox. My attic fan stopped working causing my ac to work overtime. I hired a different electrician who came out, went into the attic and then put in a new switch, which didn’t solve the problem, charged about $350 and said I should have them put in a whole house fan for between $4,500 and $11,000, depending on the options I chose. That fan wouldn’t cool my attic and would draw hot air from outside into the living space. I then called Tuscan. Jim Cox came out, went into the attic, noticed the fan was humming but wouldn’t turn unless he pushed it with his pen. He made a video of the fan for me to watch. He then gave me a very reasonable quote to replace the fan, ordered it and told me I needed new insulation. The insulation company convinced me to seal the attic with insulating foam under the roof and on the gable ends, which would completely keep it from heating up. I called Jim and asked him to return the fan, which he did without complaint. I then received Tuscan’s invoice for $0. I now know where to go for electrical, heating and plumbing work."

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