"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

"I was having a problem with MS Office not responding and other files being very, very slow to open. Jim started looking for the cause right away. He did numerous checks for viruses, malware, and various other things that can go wrong. He vigorously pursued a resolution pretty steadily for two days before determining it was a malfunctioning external backup system that was causing the problem. With that finding, he promptly got my computer running smoothly and very fast again. He made two trips to my house; on the first one, he had to cross a sheet of ice in my driveway. Jim is a very capable and experienced computer analyst that will get after your problem because he fully understands the importance of, and the need to have a working computer in the house.

"No work was performed. Angie's List has been unable to remove this from my account and I'm tired of the popups. The service coupon was offered from a vendor on the West Coast to me in VA. The company name is exactly as one listed in VA so I errantly purchased the coupon. Angie's List refunded the money but multiple attempts to remove this aborted service scheduling have failed. This is my attempt at removing it from the system and quit nagging me EVERY time I log in to write a review.

"Luke did an EXCELLENT job! His estimate was fair and didn't change mid-job. He was at my home every day at the time he said he would be and worked through the day and kept us abreast of his progress and what he would be doing the next day. Every day when he left, he cleaned up anything he used and left no mess (really we left a bigger mess). He removed the shelving systems in the closets and replaced them when he was done, moved all the heavy appliances and furniture and really, once he left, we were left with a beautiful home and no signs he was ever there. He is professional, polite and a very talented young man. We already have plans to hire him for additional projects. Choosing this young man would not be a mistake. We are amazed at the work he did and this was definitely money well spent. Thank you for your work Luke!"

FAQs for furnace / forced air heating system install or replace projects in Sardis, AL

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.
