"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

"Total Home Environmental HVAC repaired my 1994 furnace. Although the furnace was not technically supported by the manufacturer, the service technician researched the unit on-line, sourced the parts and repaired the unit as promised. I am very pleased with the results and also with the lifetime warranty."

"I thought this company did a good job. They put in the furnace and it seems to work. The problem is they never got a permit for the work. Then they never got the inspection from the city. Both the permit and the inspection were part of the contract. I do not know anything about furnaces or furnace installation. Without the inspection, I do not know if the furnace was installed correctly. Is it sending carbon monoxide into our house? I must have called them 100 times in the last year to get the permit and inspection. they simply refuse. I have sent a complaint to the contractor state license board, I do not recommend this contractor."

"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.

Every aspect of the job (planning, designing, installation, etc.) was done at a highly ethical, professional and skilled level. Based on my husbandâ  s and my experience, Top Energy Solutions deserves the highest rating possible and we highly recommend the company for heating and cooling solutions. We will not hesitate to use them again for other properties."

"We had a great experience with SoCalboys Heating and Air — solid 4/5 stars. George helped us upgrade to a Goodman heat pump, move the furnace to the attic (we gained a closet!), and add ceiling returns to improve airflow. He listened carefully, offered smart options, and never pushed. George and his apprentice were calm and friendly — even with our very loud dogs. Install day had a couple hiccups: gates and doors left open, and a heavy storage bin left on the attic drywall (thankfully it didn’t fall through). But George’s follow-through made the difference. He answered all my (many) questions, came back to double-check everything, and even threw in a thermostat due to scheduling delays. He’s also helping us navigate rebates like HEERHA to reduce the total cost. The system’s only been in a short while, but already feels quieter and more balanced. If you want small-business care, honest advice, and next-level communication, SoCalboys is a great pick."
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.
