"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"

"I had a new HVAC system installed in early November. There was some work from the installation of that new system that needed repair. I advised them of the issue and scheduled the work. They sent a technician out and he took care of it."

"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!"

"Bay Area Electrician did a fantastic job on my project!! I have a small family room downstairs and all the wiring and cables were run through conduits that were exposed on my ceiling and walls and made the family room look "industrial"!!! Ross and his team routed and concealed all the wiring inside the walls and ceiling, added a new light fixture, installed new outlets and switches and after we painted the whole room it now has a homey feel to it and is now an enjoyable room to be in!! They were on time, very friendly and gave us an excellent quote and left everything clean and left no debris!! I will recommend them to anyone!! They will definitely come back to do other projects!! Thank you Ross and team!!!!"

"Better Water Heaters Franz answered the phone immediately and is very positive and easy going on the line at all times. The business has 24 hr services, 7 days per week. Depending on if emergency, but I just needed someone to come out and help me with how to clean out my water filters and systems. I was a little scared to do it myself for fear that I would mess it up. Additionally, aquasana would not tell me a good brand of Oring grease and there are instructions on how to clean out the housings with bleach of sediment and ****, and also make sure water is run thru house, I wanted to make sure I did this right. Making sure I'm running the water thru the lines properly to prevent bacteria buildup, and unplugging the heaters and the microbial heater as well. There is a lot more to it than I expected, so I just wanted to be sure to get it right! They gave me a reasonable price for this basic check and help so I didn't feel like they were gouging me. They came down, showed me the turn off valves, unplugged everything, released pressure of water without spraying it all over (which I certainly would have messed up on). They used the housing tool to release the screwed housing, and let water flow into the bucket! I might have missed that part! They showed me how gross the water filters were!! Ick! Glad I don't have that stuff in me! It was black! I filmed the whole thing, they showed me the direction of the flow. They were very patient with me!! Then I went and washed the housings w bleach, and I forgot I had no water to mix!! So they went outside and got some out of my backyard lines. I put on gloves and discovered I didn't have special long scrubbers for housings!! They had black **** in them so needed to be cleaned. I went ahead and got some old longer bottle brush and was able to reach. I had rubber gloves on that were long on my arms. They helped me to rise the housings since it was awkward. After cleaning and drying everything so not to get bleach on floor potentially, or my clothes. They went back to putting the filters back in, showed me how to do this properly. Oh, and they used the appropriate food grade oring grease on my oring and showed me how much to apply. Screwed everything together, and then we ran the water thru the system to make sure no bleach would be there. They were very polite, nice to me. Thanks Better Water Heaters! Great decision to buy my water heater from you! And to install the filtration system!!"

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.
