"We have had a heat pump with individual units in 6 rooms for 3 years. The installation by another company was good, but the system never worked because of a leak that the installer never figured out. We hired Total Home Environmental, in part because of their fast response to my Home Advisor application. Within a couple days they had the problem diagnosed, and 2 days later Nate and Cesar located the leak, fixed the leak, and the system has never run better as an AC unit. I'm confident it will work as a heater in the winter months, thanks to Gordon and Nate Brown."

"I live in a community with a HOA board. There were changes in the rules regarding renovations just prior to my purchase which I and my realtor were not aware of. Nathan help me through the process in obtaining the needed permits and required documents. Once the work was started Nathan and his team completed the instillation quickly and efficiently. Nathan made sure everything was done to code and HOA regulations. Nathan and his team were always professional and helpful. The area was cleaned of debris following completion. I had a very positive experience working with Nathan and would call on him again if I needed any electrical work done. He is a true professional."

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

FAQs for furnace / forced air heating system install or replace projects in Costa Mesa, 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.
