"My furnace stopped working early this fall. I left messages with various companies and even scheduled an appointment with Roy's for the following week. Jake then called within a 1/2 hour and came right out. He diagnosed my problem immediately as the gas valve. I was suspicious, because a couple years ago, I had Mr. Plumber come out for a problem with my water heater, and the technician told me (without touching anything on the system) that it was the gas valve $$$, Turned out, the pilot light just needed relighting! So Jake patiently walked me through the diagnostics with the test equipment he was using and showed me the readings and explained it all to me. He then returned the next day, with the part, and installed it in no time. My furnace is back working perfectly. He accepted my check on completion of the job and sent me a receipt immediately from his phone. Extremely skilled, professional, honest, and patient guy. I will definitely call him again for my future plumbing or heating repairs!"

"FANTASTIC!! My furnace stopped working in the middle of winter while the temperature was a blustering 10 degrees. After another company told me I needed a completely new heating system costing thousands of dollars, which I really couldn't afford. I then decided to call T-MARK. T-MARK agreed to come out immediately and managed to repair the furnace, rather than replace it. T-MARK's honesty not only saved me thousands of dollars, but they were prompt, considerate, and professional. I very strongly recommend their servives."

"Great response on the weekend. Very impressed with the technician John Chumley. He was very professional and explained every detail of his work. He even took the extra time to explain other services Cellino provides. We were leak free in no time. Price was reasonable for a Sunday call. John provided the exact cost prior to any work being done. I will definitely be using Cellino in the future for all my plumbing and heating needs"

"Touchdown Heating & Cooling was great! My furnace broke on Thursday night, so I called for a quote on Friday afternoon, thinking that I might be able to have them take a look sometime on the weekend. They initially scheduled me for Saturday afternoon, but I got a call later saying that they were in the area and could swing by that same day (Friday). Chris, the owner, and Austin came by, took a look, and got me a quote for a repair, a basic replacement, and a deluxe replacement. My wife and I called around 9:00 that evening, requesting the basic replacement, and they were able to get it done by early Saturday afternoon. Chris and Austin were total professionals from start to finish. No bs, completely up front in the evaluation of the problem and in laying out our options. They quoted, we signed, and then they executed perfectly. I have no reservations in whole-heartedly recommending Touchdown H & C for your HVAC project, whether planned in advance, or in an emergency."

Emerald Heating & Cooling was founded in 2000 by Marty and Carrie Sheehan, who combine their strengths to offer great HVAC service to the local area.\n\nThe business began after founder Marty Sheehan worked for an HVAC company and trained under a wise technician who told him “be like the duck on the water.” By this, he meant that ducks always appear graceful and in control above the water, while below the surface they are trying hard to stay afloat. It’s a metaphor for working hard while doing a beautiful job, hustling without mistakes, and doing great work without the fuss.\n\nMarty has taken this mindset and applied it to every aspect of our business, from the logo to the mission. This is how we approach every job we do.

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.
