"I have been calling on Standard Heating and Air Conditioning for all of my heating and cooling needs for a few years now. I have had them out for furnace and air conditioning maintenance, emergency service calls, and when we replaced our A/C system and furnace they handled the whole installation process. Their technicians are always professional and well-trained. They really know their stuff, and they really go the extra mile to make sure we are happy. I can’t recommend them highly enough!"

"A great experience from a terrific team. After we were told by our (now past) HVAC company that we needed a new furnace, I called Design by Comfort for a second opinion. When I called their office, the woman I spoke to understood my situation immediately and had their team on my doorstep at 8:00 the next morning, on the dot as scheduled. Their service specialist took apart the furnace inspected it and showed me by video the heat exchanger that our original contractor told me was bad.
Based on his very thorough examination, we knew that the furnace did not need replacement.
Obviously, the first company did not tell us the truth about the condition of our furnace so as to sell us a new one even though it was not needed.
The Design by Comfort team was honest, professional, and highly responsive. They saved me thousands of dollars. When the time comes, and it always does, for us to get a new furnace, they will certainly get our business.

"This guy Vitale is great! He was very knowledgeable and honest! He did not try to tell me I need a new furnace like the other companies, even though that is mostly his business (installing new systems). He fired up my furnace and said I can definitely keep using my current furnace if I want to...that it was not necessary to replace it. If I decide to get a new furnace, I'm using him for sure!"

"Hoffman Cooling & Heating replaced my 2 gas furnaces which were each almost 30 yrs old. I first met with Andy to get an estimate. He was honest about what I actually needed. I was told that Hoffman Cooling & Heating strives to provide "good quality products at good prices" and I really felt like they honored that. When the team (Dan & his apprentice, Bobby, and Mike) came out to do the work they were on time, efficient, completed their work, and left the area clean. I asked a lot of questions and they were all willing to share information with me to help me understand the system and the work being done. I really got the impression that the owner, Scot, values his team, takes pride in the work his team does, and cares about those he provides service to. I would recommend HC&H to others."

FAQs for furnace / forced air heating system install or replace projects in South Saint Paul, MN

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.
