"I've been using Kettle Moraine Heating for my annual furnace and AC tune-ups for a while now, and I couldn't be happier with the service. Khamya Little was professional, thorough, and took the time to make sure everything was running perfectly. It's always a relief knowing my heating and cooling systems are in great hands. The team at Kettle Moraine consistently delivers top-notch service, they're prompt, knowledgeable, and genuinely care about doing the job right. Highly recommend them to any homeowner looking for reliable HVAC maintenance!"

"When I called, because we were looking into a new furnace and air conditioner, Cardinal sent Rick out to check things out in our basement and outside. My husband wasn't here the first trip out so Rick came back to explain what our options were to both my husband and myself. He explained what qualified for tax credits and rebates and then any add ons for heating and cooling. He explained what a heat pump was and how it worked. Then he shared his experience with the product. It was so nice, he came over on a holiday weekend, never pressured us, or was impatient, just a down to earth guy who really wanted to give us the most information to make sure Cardinal would meet all of our needs. They definitely did. Two days later their installation crew arrived bright and early and were done by early afternoon. The house felt different immediately with the in home humidifier and April aire system installed. What a difference! Thank you Cardinal for that wonderful two fur deal!"

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"Justin took care to not over sell me. Only what I needed and understood. The install team were tidy, efficient, and educated me about the safety approaches when changing the humidifier filter. That filter and the furnace filter are the same that was used on my old system. They were professional and personable."

FAQs for furnace / forced air heating system install or replace projects in Watertown, WI

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.
