"Great! I told them I would give them a call to come out and do the furnace this Fall. They were very nice, very knowledgeable and I would use them again. She told me I could get the furnace without the carbon monoxide, I could probably get it for about $69, which is pretty standard I think for what most people have around here. I've seen some people advertise for about $69. I also know the carbon monoxide, because I had one, this gave me a second one, those things are not cheap. They are $20 - $25 to buy one, a decent one. I thought the price was very fair. Their work was good. I was very pleased with them. They got a hold of me fine, it was me that dropped the ball. It wasn't them. They got a hold of me. I had the holidays coming up and I forgot about it. They didn't have to, but they reached out and still honored it and gave me the air conditioner one. To me, that says a lot about them. He was right here when he said he was going to be. She told me I could just purchase another special online through Angie's List. I told her I was going to. I would say they are very good. I would definitely call them again. I plan on having them come out for the Fall for the furnace. She even told me they could check the fireplace. They can show me how to even use the fireplace. I have been here for 5 years and I don't even know how to use it."

"I called Mike early one morning and left a message to inquire about his service that was on Angie's List. He called me back within 10 minutes ( it took that long because his office was not open when I called). I told him that this service needed to be done right away because it was at a rental property and they had no heat. He went that day to look at the problem and called me back in just a few hours. He said that because the unit was as old as it was that he was not able to get parts that were not original equipment parts but had gone to his provider and they had parts in stock if I wanted to go that scenerio. He quoted me a price for parts and labor to do the job, which I thought was very reasonable, and I told him to go ahead and finish the job. He went out the next morning, in the pouring rain, and had heat in the condo by that afternoon. I certainly appreciated his professionalism, honest and work ethic. Since I have other rental property, I will certainly call him again.

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."

"Moving into new home and needed someone to check out the heat pump. Someone recommended First Class and I’m so glad they did. Cameron came out, on time, and was very thorough, explained how the system works and the condition of everything. There price was very reasonable. I’ll be using First Class for regular maintenance once I move in."

"They are a busy company and I can understand why. It seemed like things were slow but a lot was going on behind what I could visualize. The permits and the Net metering agreement had to be approved first. After that the work began very fast. The waiting on Duke energy was a couple weeks after everything was installed but the results were extremely good. I now have a system that cools the house properly. My power bills went from $320 a month to $9.18 and even with the solar payment I am saving hundreds of dollars a month. The crews were very professional and did not take any short cuts. In this world everyone wants immediate installation and results but somethings take a little time to achieve the results expected. The company kept me up to date with the progress and the channels they had to go through to complete the process. They are very customer oriented and I would recommend them to anyone who was to save money. You have to have long term goals. Mine are going to be achieved with the help of U S Energy solutions. I thank them very much as they not only made me feel like a special customer, they made me feel like part of the family."

"Chris showed up literally the next morning after I started the project. He explained what our issue was and provided a solution. New system was installed that day and was 1/2 the price of Carolina Heating. Very pleased."

"Got a full install of a heat pump split system in my house, had them redo the duct work and all, they showed up on time, got it done in a timely manner, and i couldnt be happier with how good my house feels"
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.
