"Travis was our technician. He was thorough, knowledgeable, explained everything in detail and gave us some pointers on how to improve our system. We are waiting to get an estimate on the work but will seriously consider using this company as they were quite impressive."

"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."

"After our central AC unit stopped working abruptly this past weekend, I immediately searched online for a company to come troubleshoot the problem. Based on the many great reviews, I choose First Class and they certainly did not disappoint! Within 2 hrs of my online inquiry, I received a call back and was able to schedule an appointment for the very next day. Within 30 mins of arriving, the technician diagnosed the problem to be a loose wire on my AC unit. The technician, Jonathan Pepper, was very knowledgeable and a true professional throughout the entire visit. Definitely recommend this company to anyone looking for a truly great experience!!"

"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."

"I had an intermittent issue with my air conditioner and called on Airworks for service. Josh came the same morning and performed a very thorough diagnostic on my system. I was assured that he was a true technician and not one to sell unnecessary parts without knowing for sure what the problem is. Josh explained every test he did, and as a result I learned more than ever about my AC system. In the end, I was left with a properly working AC, a very reasonable bill, and his genuine interest in maintaining my AC system. I'll call Airworks next time I need service."
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.
