"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

"Kevin Ott came out to do the estimate. He was on time and very professional and courteous. He was very knowledgeable and went over my current system with me. I did not get a written estimate as their systems are top notch and I was looking to get a simple system. He gave me some options."

"Arrived on time and preformed the most thorough furnace inspection I have ever had. They took the furnace apart, inspected inside of it in hard to reach places with cameras and answered every question I had (I had several questions). They went so far above and beyond my expectations that they are the only company I'll use going forward."

"Went great!! I loved that he could come out as soon as I needed and the earliest available appointment.  He was prompt, professional and got right to work assessing my sump pump and drainage around the house etc.  He also took the time to lay out my options for a battery backup and work to potentially re-route my drain pipe to the other side of the house and bury it to feed out to the forest vs right next to the house.  I felt way more informed that I had previously been.  He was able to complete the work quickly, efficiently, cleanly well under an hour.  Also, while he was there I asked if he could take a look at my furnace, I could not figure out how to replace the filter and he was able to show me right away.  I greatly appreciated this because I was really perplexed by this matter!!!   I found out My Service Pro does a variety of work and repair and I was happy to keep his information for future use.  I would definitely use My Service Pro again and recommend this company to my neighbors and friends.

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