"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"Replaced my gas furnace and air conditioner with a heat pump. The only company I contacted who did a thorough analysis of my home and electrical system to determine exactly what I needed. Side note: I requested this service because my furnace quit working. The technician who came out to evaluate my home repaired the furnace for free while doing his analysis. I still bought the heat pump, but this company definitely did not simply try to just sell me one."

"Victor and his people were amazing. They were professional, communicative, effective, courteous. They also knew exactly what they were doing and it was very apparent that they were knowledgeable and experienced and did their work with confidence. They fixed my AC and resolved all my issues quickly and effectively while keeping me informed through the entire process. I only trust them moving forward to care for my system. I have hired them to come back every 6 months moving forward to care for my system. I am 100% satisfied and highly recommend them."

"Oscar arrived when he said he would, fixed the furnace promptly and suggested a couple of useful upgrades if I want the system to operate more quietly (which I do). He will email his proposal and I can choose to get the work done or not. He's great. Highly recommend!"

FAQs for furnace / forced air heating system install or replace projects in Granada Hills, 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.
