"ok except the shower install. Bad install wrong caulk used around tub, had to come back to replace about three weeks later. 8 months later caulk coming loose from tile around tub and small holes in it in other places. They came back to redo and I thought they had scratched my tub they would not come look at it (turned out I was wrong and apologized for it. Now grout coming out and caulk loose again, after many phone calls (4, we will call you back and 5, we will be there no one shows and no calls to explain why. They send a guy to do the caulk. not grout, more calls more no shows finally they send a person, with no experience to do the job. Was told they were bending over backward to please me when all they were doing was taking care of their mistakes they created. Ever time I question no show and no call was told a emergency came up and I wasn't priority (One bath house). This stuff should last for years and not just months."

"I cannot say enough good things about Bob. He went above and beyond in every aspect of the job and was a true stand-up guy from start to finish. He worked in a very timely and professional manner, communicated everything clearly, and genuinely cared about making sure the project turned out right. The closet system I ordered from Amazon actually came with a piece that was manufactured incorrectly. Instead of giving up or leaving the job unfinished, he let us know immediately and then did everything he could to make it work. Thanks to his effort, problem-solving, and attention to detail, the end result turned out amazing. I honestly couldn?t be happier with how everything came together. I would recommend him to anyone looking for someone reliable, hardworking, and committed to doing quality work."

FAQs for furnace / forced air heating system install or replace projects in Fairfield, KY

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.
