"These guys are Great! Jeff arrived within the time window with two other workers. All of them were friendly, knowledgeable and clean. I was just getting a system tune up, and they made sure to truly inspect and clean both my air conditioner and furnace completely. They found two things that I should address in the near future, and Jeff explained to me in detail what had happened to the units and if repaired, how much money it would save me in the future. Most companies would have tried to sell me a whole new unit. These people are Very Honest!! I'm going to scheduled to needed repairs within the month, again as recommended by Jeff - not pushing me to get it done on the spot. I am recommending Allstate to all of my neighbors and friends!!!"

"The big contractors in the Phoenix area generally will not install equipment they do not sell you themselves. And they rip you off in the process. Climate Group Mechanical is a newer company owned and operated by Robert S. He installed a system I purchased on Amazon for a fair price. He did a great job. He showed up on time and got the installation done in a very professional manner. I would recommend him highly. By using CG Mechanical for installation and purchasing the equipment directly I saved 50% ($3,000) on this job. Do the same!"

FAQs for furnace / forced air heating system install or replace projects in Casa Grande, AZ

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.
