"I needed my laundry room drain unclogged. I posted the job on Saturday night for work to be done on Tuesday morning. Jim called Sunday morning, said he was available that day. Came out relatively quick and the job was done within the hour. I highly recommend Jim. I'm certainly going to give him a call the next time I need work done."

"Chris was very polite. He was punctual and gave me plenty of notice of when he would be here. He installed two huge ductless heat a/c units. He was very knowledgeable and gave me options for different units. I saw him measure at least twice and used a level to ensure everything was level. I loved his attention to detail. He seems extremely trustworthy. I felt very comfortable with him. I will recommend him to anyone I know who needs this type of work."

"D & B Heating and Cooling went *above and beyond* to help me with my (lack of) air conditioning. My A/C unit went out on a Friday evening. I had reached out to several other companies with repair service requests, but my situation wasn't considered an emergency. Out of desperation and frustration, after several days and a 100-degree July 4th holiday with no A/C, I reached out again for help via this site. D&B responded within 3 hours. They were at my house from 8:00pm thru 9:30pm (yes, in the evening as it got dark) diagnosing and trying to fix the problem, and were back at my house at 8:30am the next morning for the final repairs. My A/C unit had been been hit with lightning. D&B successfully did their best to 'unstick' and refurbish the slightly welded parts, rather than installing new parts or recommending a brand new unit, which of course saved me a lot of expense. I was extremely impressed with D&B's responsiveness and commitment to superb customer service. They are great guys doing honest work. I highly recommend them and will absolutely call them for any future services needed."

"David is great! He did an excellent job installing our home Radon mitigation system. He worked with us to determine the most effective and efficient way to set up our mitigation system. The system works great! Our Radon levels were very close to 0 after the initial install and almost a year later they are still very close to 0, currently measuring at 0.8. He was very professional and responsive throughout the entire installation process. We would highly recommend Covenant Air for help with decreasing the Radon levels in your home.

"I was very impressed with the service. They came out on a very cold, rainy and miserable day and repaired our heating system and then came back a couple of days later to "tweak" it without any complaint. They were courteous, efficient and got on with the job."
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.
