"We have been using Golden Aire for maintenance and repairs for the past 8 years. They are professional, knowledgeable and courteous, as well as fair in their pricing. Case in point, we had Daniel come out to do our summer A/C maintenance. Daniel discovered that coils were bad and leaking coolant. We received our quote for the parts and repair. The cost was estimated at $3k (ouch!) Parts were ordered and Daniel came out within a weeks' time. I can't state highly enough how impressed we were with Daniel's knowledge, professionalism and most importantly care. Daniel was able to save us $1,300 as he discovered that after fixing the Nitrogen leak and replacing the refrigerant there was no need to replace the coils. I know other less scrupulous companies would have milked us for a higher invoice price especially since the coils were ordered. Thank you, Daniel, and Golden Aire for your honesty and professionalism."

"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"They installed a new Heating & Cooling system in my house. The work was very clean and professional. I do most of the work around my home so I know exactly what to look for, and they did not cut any corners. No detail was skipped. Their price was reasonable and there were no hidden or gotcha fees. They went above and beyond and didn't try to charge me extra to get the premium service I received. I knew nothing about this business until a friend recommended them, and I am glad I did. I would highly recommend them to anyone."

"I have had Guerrero's out to several of our residential properties over the years. This company has replaced two units for us. A ground unit and a roof unit. They have also replaced old thermostats with new eco friendly ones and fixed other problems like a dead capacitor (took 15 minutes to diagnose), bad board, etc., very quickly and for a reasonable price. They show up at the time they say they will show up. That means a lot to us. I absolutely do not want to be waisting hours of my time waiting on a contractor that may be running late but doesn't have the decency to call me. Guerrero's does quality professional work in a timely manner. I can trust this company is doing me right and not over charging me and will do a professional job in a timely manner. We are very lucky to find Guerrero's and will continue to use Guerrero's for any of our AC/Heating needs."

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