"We had our tankless water heater drained - annual maintenance. They show up when they say they will and do it right the first time. In the past we've had issues with AC's, plumbing and more. Evey time they've exceeded our expectations and would highly recommend them for any heating, AC or plumbing. We've used them for well over 20 years and wouldn't want anyone else. They are the best."

"I'd like to take a moment to share with you my experience with Air Care Heating and Cooling who recently installed a new heating furnace replacing our original heater from 1976. After interviewing four reputable local companies in San Diego I chose aircraft based on excellent reviews on Google and Angie's list. Mr Michael Santana (Owner and founder) offered very affordable pricing compared to others not forsaking the quality of/ furnace unit, warranty and exemplary customer care /service. The installation process was flawless. Mr Santana's and staff demonstrated outstanding professional performance, effective communication to answer questions and concerns even adding extras like replacing events and the job completion in a timely manner making the whole process from beginning to end a truly"

"After recovering from a horrendous experience with Service Champions (NEVER EVER call them), I got several other quotes to completely replace my old AC system.

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