"

We moved into our house about 3 years ago and the first thing we wanted to was get a heat pump. They were very friendly. When we were about to have the heat pump installed our sewer pipes backed up we ended up having to replace our sewer pipes and the heat pump at the same time. right after we bought the house. Both companies worked with us on some payment options without financing.

about a year later we wanted to get our heat pump removed from our basement. So we asked them to come out again to see how much it would cost to have it removed. It was the same guy who came out the first time. He told us that to remove it he would have to charge us about $3800. He told us not to have them do it because he didn't want to charge us that much. He recommended an alternative for us which worked out and save us a lot of money. I will always use New River Heating and Air for my projects because I know that they will do what's best for me not just their bottom line.

"They completed the heat pump installation work but did not come back to install a new filter rack system. I have contacted Mr Tilley three times for him to schedule the work. He came to my house but after two weeks no work has been scheduled. I am disabled and cannot change the filter without a great deal of discomfort, so I really need the work done. Update: The service took about an hour to complete."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"We are pleased to recommend Triangle Reconstruction with our highest praise. It seems too simple to say that they do what they said they’d do, but that’s exactly what happened. Our home is around 50 years old. Ours was a large job - around a month and $30,000. We had Triangle Reconstruction come in after another moisture company provided mold remediation and a humidifier. I wish we’d contacted TR to start with. We provided TR with a structural engineering report. They created a plan to exactly meet all of engineer’s concerns. TR used temporary supports and replaced seal plates, girders, and joists for over half of our home. In addition, they poured footers and built new columns. They also added a few additional girders to firm up our floors. They removed and replaced our insulation. They sealed our porch and crawl space, replaced our vapor barrier, and installed a moisture meter. They wrapped our electrical cords and hung them. The people at TR are remarkable. A+++++"

"Our furnace motor was making a loud noise, and Chris Suttles came by and diagnosed the problem shortly after I called. He fixed the problem that afternoon, and the furnace is now quieter than it's ever been. I asked him to come by the next week and give the furnace a tune-up and clean the heating ducts. When Chris opened one of the supply ducts, he found the inside of the ducts had a sticky, oil-like coating. I decided to replace the ductwork, and he replaced all of the ductwork in 2 days. The air coming out of our vents is now cleaner, warmer, and stronger."

FAQs for furnace / forced air heating system install or replace projects in Christiansburg, VA

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.
