"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"Jason completed the repair of 7 Oil heaters, full blower wheel replacements, nozzle head replacements, tune up and more. For the first time in 15 years all heaters run SILENT and they are 18 feet in the air in a mechanic shop of a dealership. He then served all 5 A/C units on the roof of the dealership. Ever since we hired him it has been seamless and very fairly priced. I would highly recommend him and his company. He's always available for any emergency we've had regarding the units."

"I woke up the last week and my bedroom was freezing cold. I called Arvada Heating because they had really great reviews online and they didn’t disappoint us at all. They sent over a technician and within an hour or two the tech was able to restore our heat. 5 stars for Arvada!!!"

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"I would highly recommend C&A Mechanical. Craig and Alex are true professionals and excellent at what they do. They are prompt and clean. They installed two new air handlers and two new compressors in my house, and redid all pipes and wires. They are very reasonably priced and very nice to deal with. I am so glad I went with C&A! Alex spent many hours up in the attic in near 120 degree heat and didn’t complain one bit. They completed the job exactly in time frame they told me at beginning despite running into some complications. Honestly, they are a Diamond in the rough! I really can’t say enough great things about the experience with C&A! Thank you Craig and Alex!"

FAQs for furnace / forced air heating system install or replace projects in Greenlawn, NY

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.
