"Beyond my expectations! Bill Worlock and his professional crew did an amazing job installing my rooftop AC system. I was going to attach some photos but no way to do so. His process included a very thorough review of the requirements based on the size of our home, the best unit for us and he explained in detail why. His team showed up a few minutes early and got to work. Since the job required a crane to hoist the unit to my roof, they managed to work around the other delivery trucks who were delivering furniture and appliances. They are fast! When the job was completed Bill showed me the laser temperatures for the heat and the AC and explained how the new thermostat worked. I had a new AC installed three years ago in another home I own a few miles away and I wish I knew Bill back then. When they left our second home his team greeted me and were appreciative to do the work. Not too many times I can remember the workers thanking the customer. I'd recommend Worlock for your AC needs. I've got pictures of the "before" and "after" and glad I hired Bill's team."

"We called several HVAC companies trying to get our AC fixed. Two well known companies told us we needed to replace the entire system, even though it’s only 8 years old. Before spending thousands on a new unit, we decided to call Precise Air & Heating for another opinion. Their technician came out, found the actual problem, and had our AC up and running that same day! They saved us thousands of dollars and never tried to sell us a new system we didn’t need. It’s hard to find an honest HVAC company these days, but Precise Air definitely earned our trust. We won’t be calling anyone else for our heating and cooling needs. Highly recommend!"

"were right on time, explained everything before going up to shut down my cooler. When done he came back down and said he was finished and talked to me about things I should think about doing with my air conditioner for next year. I would definitely use them again."

FAQs for furnace / forced air heating system install or replace projects in Chandler, AZ

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.
