"My furnace was leaking all over the cellar floor when I called Petro at 9 PM on Sunday night - turned out I needed a new expansion tank and relief valve. Petro had a tech here within an hour. Tommy Polizzi, Jr. (Tech #83), was professional, courteous, and kind as he explained what was needed and why, then made the replacements, again, within an hour. Thank you, Tommy, and thank you, Petro."

"Heater started to leak a bit but still had time to do my due diligence comparing quotes. I found good review's for rob here at angie's list and called him up for a quote. Rob came by and gave a fair quote.

"I am very happy with Mikes Air Conditioning. Here it is JULY and I while in the middle of doing some renovations to my home, I noticed the AC wasn't working the way it should be. I contacted Mike's (fearing the worst) and they sent out a service technician who was able to repair the system for a reasonable cost and buy me some more time before I have to replace the entire system. I had some minor work completed and the freon topped off and now I'm cool and comfy!  Considering all of the expenses with renovating I was very happy to not have a high repair bill. Mikes was efficient, conscientious and professional and they completed the job on time and for a reasonable cost. I recommend them for AC repair as well as installation of new units. When I'm able to replace my system, I'll be calling Mikes Air Conditioning to do the job. Building relationships and getting repeat business should be the goal of any business. I'm glad to see that Mike's takes customer service seriously.

FAQs for furnace / forced air heating system install or replace projects in Frenchtown, NJ

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.
