"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!"

"Ricardo can’t and did a thorough inspection of the unit and ducting. We discussed the units inability to keep up with the summer heat. When he inspected the condenser unit he found it to be undercharged and recharged it. The unit is running like new. We will have Ricardo come out again in the fall to measure the charge and discuss the severity of any leaks"

"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."

"This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."

FAQs for furnace / forced air heating system install or replace projects in Temple City, 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.
