"After recovering from a horrendous experience with Service Champions (NEVER EVER call them), I got several other quotes to completely replace my old AC system. Brandon and HD had the most competitive quote, great reviews and were very personable and professional. They installed entire new system and did a great job in a timely manner. I highly recommend!"

"The blower motor on my furnace went out. Every company I asked for a quote told me I needed to replace the entire furnace and quoted me thousands of dollars to do so. I hired Cool Air For You and the tech came out the next day and replaced the blower motor in a few hours. The AC and heating works again and I didn't have to spend 4 or 5 figures. Highly recommended."

"The Tech went above and beyond to do my inspection and service. I did nor buy the yearly maintenance plan and I did not buy the $190. furnace filter ($20) at Home Depot. I had and still have a problem with the system. It makes a growling noise every 2 minutes or so. Thanks so much, anyways."

"First off, Bernie is the owner and will be personally involved in your project. He has a wealth of experience and knowledge. I really appreciated how Bernie approached the project and how upfront he was about making certain changes and how they would affect the home cooling/heating situation, or the overall project success. He was very detailed in his approach and his inspection - the only one of the bids that I received that actually inspected the venting in the attic, rather than guessing by the age of the home. I HIGHLY recommend Bernie and Air ASAP and believe that this local & small business will continue to have great success in the local South OC markets!"

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.
