"I honestly cant thank Behold heating and cooling enough for an amazing job. Our whole heating system went out and needed a new one! We called other places and there prices were ridiculous! Not only were the prices ridiculous but pushy and they lied about many things about our furnace. Behold heating and cooling are hands down and an amazing company! Big thanks to the install crew Hunter and Jose! Thank you for gor being honest and amazing! I would recommend Behold and cooling for everyone."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

"So far as I can tell, the quality of the products and the quality of their installation was fine. The furnace includes PVC pipe venting both to bring combusting air into the furnace from the outdoors and taking exhaust gases outdoors through another PVC pipe through a concentric vent in the outside wall. This process is designed to prevent any exhaust gases in the basement or any bad negative air pressure in the basement. The furnace is an energy star with 95 percent efficiency. The only negative aspect of all this was Controlling Systems' behavior relating to scheduling as described in the section above."

"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

"I put in a text in on Ange for a furnace repair. Within seconds I received a call from Brent, with A-Moonlight. I tried to explain our problem with our furnace short cycling. He said he could be out within the hour to check it out. Brent was very punctual, and brought David, his helper, with him. Brent was very knowledgeable and explained how and why things were not working. We received a new furnace, and Brent and David worked very efficiently installing the new unit. I am very happy with the work Brent and David provided. They were both very courteous, and cleaned up afterwards. I will definitely hire Brent again if the opportunity arises. Definitely the definition of pride, and quality work I was looking for, Thank you!"

"Furnace quit working in the evening just prior to a forecast -7° temp. Tech responded within 30 mins; I needed a new Furnace. They left me with a space heater to keep me warm until the following morning when a crew arrived and installed the new Furnace. Great service--very professional."

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.
