"Matt came in and replaced a bad ignitor and cleaned what needed to be done in our furnace, when almost all others only would replace the whole thing. He was done in 15 minutes and we have heat! And the price was great! Such wonderful service even in this covid-19 climate, we all had on mask and social distanced!"

"Air Concept quoted me a very reasonable price on cleaning 2 wall furnaces at a duplex recently. I had one other quote before for an outrageous price. Charles, the owner, was very honest about the work that involve- only vacuuming off the dust inside the furnace basically. The two employees were punctual and courteous. I thought they would include vacuuming or wiping down the furnace cover as part of the cleaning. They did after I asked about it, so they did one cover at the 2nd unit. That's why I took off half a star. Other than that, I am satisfied with their work and would recommend their service again."

"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!"

"They come out and do the service okay. They are too pushy to try and sell you on a new heating system. You can make an appointment for a new system and they don't come out. They're known to be high. I think they are high. When they come out, they will call you ahead of time."
Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer.  This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

FAQs for furnace / forced air heating system install or replace projects in Fairfield, CA

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.
