"Service man arrived as expected and performed the annual maintenance of the air conditioning system. The work was thorough and it was something that was familiar to me as I used to do in my younger years. With heavy use of airconditioning in the summer in CA, this is important and something we do every year.

"The tech arrived and gave an estimate well under most others. His team arrived and replaced the heating unit same day! It was one of the most efficient and pleasant transactions I've ever known. Highly recommended."

"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!"

"We recently had Same Day Heating and Air Conditioning come to our house to inspect our furnaces before turning the furnaces on during the cooler winter months and they discovered that both units had gas leaks. The system is 20 years old so it wasnâ t a complete surprise although we had hoped to put off replacing them for about 1-2 years. The technician/ inspector was knowledgeable, thorough and professional in showing us pictures of the worn, damaged furnaces (2). He explained the options for repairs and replacement as well as pricing considerations. In the end we decided to have them install 2 new furnaces and 2 new heat pumps to replace our old AC units. The installation was scheduled and completed within a short time frame and done with as little disruption to our home and family as possible. Efficient and neat in their work, I can happily recommend Same Day Heating and AC. I am very reassured knowing that my furnaces and heat pumps can effectively and safely heat and cool our home for our family. Peace of mind is priceless when it comes to protecting your family."

"On initial inspection, they discovered that our old heat registers were the kind with asbestos (house built in the 60's), so they had to sub out the abatement part of the job. Once abatement was complete, the workers showed up each day at the time they said they would arrive. They were all friendly and professional. They kept everything clean. The took pictures in the attic to show me before, during, and after the work. They explained what they were doing and showed me the new ducting they were installing (quiet ducts) and explained the more "up-to-date" way of putting in the duct work than what we had. After the work was complete, we noted that the furnace ran much quieter (due to new ducting), and it ran WAY less often. The house stayed much warmer while running the furnace much less often. Best of all, our gas bill dropped! Now that we're moving into summer, the house seems to be staying cooler on these warm days. We don't have A/C so we're hoping the new insulation will keep the house cooler as the days continue to warm up. Very happy with the company and all the work they did. I would recommend them!"

"We were impressed with Jason’s presentation of the Mitsubishi system, and we really appreciated learning about the HERO program from him. We got a good estimate,ate for the work but were planning to do our roof repair first with adding solar and thought we would do this job after. Things worked out with that Jason got our work scheduled and done BEFORE the roof/solar which worked out because in Sept/Oct we still had some hot days, Thie crew was professional and extremely hard working, and poor guys, in hot weather, sweating in our attic/crawl space. Which they left with improvements! The system was up and running (2 downstairs units, 4 upstairs) in 6 working days. After a week we did have a problem, nothing worked and they came out promptly to troubleshoot, ordered new circuit board and installed as soon as it arrived. Been running fine since then, and this is also heating so I am looking forward to heating with solar instead of gas."

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

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