"After meeting Ron the owner, he educated me of the benefits of replacing my 25 year old oil furnace and central air unit with a very efficient HEAT PUMP/AC unit. A real no Brainer decision. All electric, energy star rated and no more fuel oil. After a very reasonable quote, with veterans discount, I said I'm in. Two of his Team showed up on a Wednesday around 8am and by Friday around Noon my AC was on. Friendly, professional, attention to detail. Would highly recommend Cawiamca for all Heating and AC projects. Great company."

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

"Jeremy was super knowledgeable and very courteous. We had needed an emergent home repair and he arrived promptly to repair the wiring on our water heater and did not leave until we were able to take warm showers- around 11 pm that night. He even tried to sweep and mop our floors!! He then made time in his already booked weekend to help us upgrade an outdated breaker box out of concern for our safety when many other local electricians tried to put us off until well after the weekend. I will certainly be using his services for years to come and I suggest anyone looking for a kind, knowledgeable, TRUSTWORTHY, and genuine electrician pick JMP as well!"

FAQs for furnace / forced air heating system install or replace projects in Killingworth, CT

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.
