"Airv Serve installed our original, complete AC/heat pump system. After our system was hit by lightning, they quickly came out and accessed the damage, replaced one of our units, and performed maintenance on another. The charges were exactly as quoted. Our new system runs beautifully, and their service was timely. We highly recommend them."

"I want to thank Angie's List for helping me know about local companies and all their information, to make a clear choice. I called the company and talked to the lady in the office. She was really helpful and explained the differences in the systems, cost and answered other questions I had. She took her time with me and didn't 'talk down' to me but made me feel at ease and knowledgeable of the products. She said she'd have Mike, owner, come out to check the unit I was telling her about and answer any questions I had. He was right on time and was great to explain everything in terms I could understand. He checked the unit and told me what was wrong and my options. I never at any time feel pressured to have it repaired or buy a new unit. I had all the information I needed to decide, and I took overnight to decide. He put a new part in my old unit, to get it up and running. He said he'd leave it in place while I was deciding what I wanted to do - repair or replace. My unit was about 20 years old, and was at the time not working. He was very nice and thoughtful and never pushy or intimidating. When the unit was installed several days later, a new thermostat was also installed. I was given instructions on it and how to set it up with my computer and cell phone. The old unit, and all the mess involved in the installation, was cleaned up and hauled away. I'd recommend this company to anyone. Great job and the nicest people."

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.
