"I shopped around quite a bit before choosing True Air. Pete was very knowledgeable and didn't try to push or oversell me on anything. Matt and the crew were very professional, efficient and friendly. Installation was straightforward and quick. The crew were very respectful of my house & property and quick to clean up any messes. I would definitely recommend them to anyone looking for a replacement HVAC system."

"My AC's secondary drain was leaking due to a clogged primary line. Daryle from Cool Air quickly identified the issue and cleared the clog under the master bathroom sink — about a gallon of water came out instantly. The final charge was a bit more than quoted, but Daryle was honest, efficient, and didn’t try to upsell anything. After bad experiences with Service Champions — who I believe sabotaged my system — working with Cool Air was a relief. Vadim, the owner, was also great to talk to. I’ll be using them again."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic.

"Bernie came out to give me an estimate an a complete air conditioner, furnace and ducting system and to relocate the new AC condenser to the side of the house. First impression he got here 10 min before the appointment, very friendly personable courteous and professional. Explained everything he is going to do, he gave me a killer price on the job, i said let's do it, later i changed my mind wanting a different brand name system he was very helpful and immediately changed my order didn't give me any attitude. Few days later they came back for the actual installation everything went butter smooth. They put tarps down to protect the carpet everything went without a hitch i totally trusted him on the work and i wasn't worried if something is going to be missing later. I would highly recommend this guy great customer service and great quality of work along with great prices."

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.
