"Arizona Rug Co. recently completed cleaning and restoring our rugs for us and we could not be more impressed with the quality of their work. The older and larger of the rugs no longer looks 42 years old. I recommend, as a designer, taking care of quality rugs in order to enjoy them fully. It also needs to be said that this company has a varied selection of rugs available from the well stocked showrooms, both in Tempe and Scottsdale, with knowledgeable sales staff."

They are a pleasure to deal with. They are professional, very knowledgeable, courteous, prompt, neat and complete jobs quickly and on schedule. I would hire them without question again, and recommend them to anyone."

"I recently had the pleasure of working with Schede Plumbing and Heating, and they were a lifesaver when it came to fixing my central air issues. As a new homeowner, I’ve been faced with different challenges every day, but knowing who you can trust and ask for help makes all the difference. I was fortunate to be introduced to Schede Plumbing and Heating, and they exceeded my expectations. From the moment I called, they were quick to respond and provided a thorough analysis of the problem. They walked me through the options and suggested the most practical and affordable solution. I was serviced by two highly professional, polite, and skilled technicians, Paul and Randy, who were truly exceptional. Paul and Randy were efficient, trustworthy, and very customer-focused. They assured me that they wouldn’t leave until my issue was fixed and took the time to ensure no other issues were lurking. Their dedication to solving my problem and their attention to detail were impressive. I cannot recommend Schede Plumbing and Heating enough. They are a reliable and professional team who genuinely care about their customers and their work. Thank you, Paul and Randy, for your excellent service!"

"I was having a problem with my oil furnace on a cold night and made an emergency request to Wtech22. Within minutes I received a phone call back from a PRO asking me how they could help. Then Wilson arrived within the hour to my house, was very professional and was able to fix the problem very fast. The Pro was able to take apart my furnace to find the problem, had all spare parts needed at hand, and I had him clean and do maintains to the furnace at the same time since he was already here. Thank you WTECH22 and Wilson for taking all the stress from me and getting our heat working fast on this cold night at a great price. Keep up the good work and I will definitely recommend you to all my friends and family."

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