"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.

"A moment ago This company is great. Roy Villa the service technician was very knowledgeable. No threat of up selling. Just explained what was wrong with the heating system and fixed it. This is for a rental house. He told me about the warranty plan they have for heating and AC. It was extremely reasonable. Now I will just have the AC and heater checked before each season."

"First we called the company we had delt with in the past, that got us no where. So we went to Angie’s List and found Carini. One of us has Lupus and get very sick from extreme heat like we have had recently. It was the same day as the West Fire in Alpine. Omar came out the next morning and gave us two options he could do right away, we made our choice and he did just that, got to work. Omar was very polite and showed concern for our situation. We will definitely use Carini and Omar in the future."

"Michael offered great advice on where to place our new tankless heater and his team did a great job executing. There were a few hiccups that came with replacing the old tank heater and working with the old plumbing of the home, but Jax Mechanical were able to solve any problems that popped up. Michael was also proactive in the initial discussion and found that our PRV needed replacing which was something we were glad he found before it led to any long term issues."

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