"In preparation for replacing my HVAC system, I went through a few different estimates. The reason I chose Air-Tech was not because of price, but because I was impressed by the details provided to me. Rod was great. We went into the attic, reviewed all the components inside and out. And we discussed the scope of the work. Once I agreed, he gave me a start date\time. The crew showed up on time and worked hard for two days. Not only was I comfortable with Rod, but the crew was great. My new system is in place and I couldn’t be happier that I chose Air-Tech. If you’re in the market for a new HVAC system, do yourself a favor and call them. You won’t be disappointed."

"Top energy solutions did a highly professional and skilled job in installing two furnaces and two air conditioners and also remove and install new attic insulation in my home. One furnace was gas and one was heat pump electric. If the installers were supposed to be on the job at 8:00am they were here. The installers were highly skilled and cleaned up at the end of each day.

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."

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.
