"This was absolutely the best service I could have imagined. My vents went from filthy to spotlessly clean. I feel as if I can breath again. The value for the services provides was excellent. The technician, Elie, was fantastic. He was so service oriented and treated my wife and I like his own family. He worked with us on pricing so it was affordable and he gave us a ten year "club membership" for only $999.00 which gives us ten years of maintenance, twice a year for the next ten years to keep our heating and cooling systems updated and clean. I strongly recommend The Right Choice Heating and Air. They are fantastic. Thank you, Elie, for everything and keeping my family healthy! You're the bomb!"

"Perfectly! Bill and his associate arrived when they said they would, diagnosed the problem, left to pick up the required part, and returned with the part and installed it, all without a hitch. I particularly liked the way Bill checked to be sure all the functions of the furnace and air conditioner were working before he finished. This is a top-notch service company!"

"I was looking for a company to replace my hydronic heating system and inefficient condenser with a new heat pump condenser, as well as a new furnace system to support the heat pump condenser. I reached out to two companies and OC Excel quoted me a much more reasonable price, and both company informed me at the time of quote that they would need to cut open a portion of my condo’s ceiling where the furnace was at, but they will patch it back/know someone that would patch it back. On the day of the job, OC Excel did everything they could to avoid cutting my ceiling, so I wouldn’t need to patch it back later and have the marks, and they were able to do it! I really appreciated them going the extra miles for me!"

"Unfortunately, I needed an HVAC company to fix my AC during a heat wave. Most companies were 5+ days out before they could even diagnose our problem. Called 3 highly visible companies, from their marketing, who said they wouldn't even work on our unit. I went with a referral from a neighbor, mistake. This company took a week to get to us then the tech went MIA for 5 days with no contact when he said he would be back tomorrow with parts. Won't mention their name as there could have been multiple uncontrollable reasons why. I then did a lot of research on different companies across multiple review websites (including Angies) and Excel Air stood out. Once I spoke to the office staff, great experience, they had a tech out to our home in 2 days with our problem diagnosed. Our tech's name was Lucas who was efficient with his time, talked me through what was going on and gave us our estimate which we were happy to move forward with. Lucas fixed our problem in under 20 minutes. Me being me, I watched each step and saw the quality work. He even put in a fuse to ensure the same problem didn't happen again to our transformer. Once he fixed everything and got our new thermostat power, our AC has been working perfectly ever since. I'm now a really big supporter of Excel Air. Their office staff worked with our insurance company after hours and actually updated us (what company does this these days) the entire way. I can't tell you how impressed I was from their office, Lucas and most of all their successful resolution of our problems with our AC. Thank you Excel Air!"

"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."

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