"My 36-year-old heating and air conditioning system, which was original to my home, had been on borrowed time for some while. I researched and got bids from four local companies. I needed a new heat pump and air handler at least, but I also wanted to replace the insulation and duct work since it too was old and I had had some rodent issues in my attic some years ago. Insulation upgrades also qualify for additional SMUD rebates. Not only was Huft's bid the lowest, but my Bosch system is more energy efficient than any of the other systems quoted me and whisper quiet. From the salesman Glenn to the installation lead Tever and the insulation installer Anthony, I was impressed with their level of punctuality, courtesy, and professionalism throughout the process. In fact, Glenn was the only salesman who actually took the time to take measurements at my house and explained the numbers of why I needed a three-ton system. I am very happy with my system thus far and I would highly recommend Huft to others!"

"Smart Heating and Air Conditioning was the most professional, friendly, and knowledgeable company I’ve worked with. From our first contact, we felt like we were working with family. Our furnace went out and the techs and installers were all so amazing with keeping us all informed, especially Susie who works in the office. But what really showed me how great this company was, is that they saw our handle to our screen door wasn’t functioning and they were so kind to offer to fix the issue. They fixed it in 5 mins. You don’t see this type of generosity anymore, so we appreciate that! Our furnace and air were replaced for a great price and we couldn’t be happier. I would highly recommend this company for your heating and conditioning needs!"

"I was fortunate to receive service on the same day I called. My issue was difficult to diagnose, as many have tried before. They were willing to step in and try to resolve my issue for good. They were successful at their first attempt. I am grateful to Guerrero Heating & Air this Labor Day weekend of 100*F+ weather."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"Peter, and his crew, were very reliable and professional. I purchased a new RUUD furnace and A/c. Their price was better than the other 3 bids I got. Everything was inspected by Archon. The final permit/inspection was issued. The system has been up and running for 6+ months now. No problems."

"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan!"
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.
