"We hired Bill Aitken Heating to repair our gas furnace, we had an accumulation of water in the furnace pan. I called Aitkens Heating and received a call back immediately. They were here promptly at the time scheduled for repair. Mr. Aitkens had my furnace repaired within a half hour. He arrived with his helper and I could not be more satisfied with the work these gentlemen did. Bill took the time to explain in detail what he did for the repair. Bill Aitken is our GO TO man for any of our heating and air condition maintenance. I would like to add he was very reasonable. My husband was not available to over see this project so I handled the whole project from start to finish. BILL AITKEM HEATING LLC. comes very highly recommended by the Perkins family."

"After another vendor recommended major repairs to a central AC system, so I called Parker Heating and Cooling to get another quote. Although I did not ask for a diagnosis, Jeremy inspected the system and discovered an overlooked minor problem, which he took care of. His diligence and honesty saved us thousands of dollars! Jeremy was very responsive and easy to deal with and checked back to make sure the problem was resolved. These days "five stars" has diminished in meaning, but this truly was excellent service!"

"Scott was wonderful to work with. He first tried to give me a self fix over the phone to same me a maintenance call. This did not work so I called Scott back to schedule an appointment. Scott came out the following morning and identified the issue was more complex after his own inspection. He fixed the issue and gave me some tips on self maintenance for my Heat Pump heating and cooling unit. I would highly recommend Scotti Mechanical Service and will definitely using Scott for future routine maintenance and/or other issues with my heating and cooling system."

"John was awesome. He was professional, friendly and very knowledgeable. I had previously had some repairs done to my central air system by another company. That result was not up to my expectations. John from Quiet Corners came out, accurately diagnosed my problem, and came out within a week to install a new condenser. We now have cool air in our house. They also work with American Home Shield, which covered most of the cost of the repairs. Great Experience!!! I highly recommend them.."

"Hiring Williams & Assoc. has turned out to be one of the best decisions Iâ ve ever made! From the very start, this experience was excellent! Bruce and his team were professional, kind, and helpful when describing the system we purchased and answering the hundred questions we had along the way. Their attention to detail and all of the little extras one wouldnâ t even expect to receive were provided as if it were second nature to them. And the team worked tirelessly, without stopping until the job was finished. We were happy to have them in our home. These are genuinely good people. Our old boiler was past the point of being dangerous. Smoke filled the basement every time it came on. Anyone could see that we were in an emergency position and had no choice but to replace the old system. Some companies Iâ ve dealt with in the past would have taken advantage of our situation. But not Williams! The price for our new high efficiency heating system was very â veryâ reasonable. Due to our situation, the work was started and completed almost immediately and the service was excellent! My wife and I highly recommend Williams & Associates."

"I returned home from a conference to discover my boiler leaking, leaving me without heat or hot water and concerned about potential damage. Steve, a highly skilled and friendly technician, clearly explained the scope of work and costs before getting started. He completed the repairs within a few hours, and the system is now working better than ever. I feel secure in my home again. Excellent work and a great overall experience."

"Great service. Came ready to work. Very pleased."



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.
