"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"Came quickly and diagnosed the problem with my furnace. Had to order a new part but was able to get it and install it the next day. My heater is working better than before. And it didn't cost me an arm and leg."

"Polar Bear deserves EVERY STAR possible for the level of customer service, quality of work, and honesty that they provide to their clients. Joe Kelly, the owner, is genuinely one of the most knowledgable and helpful people we've ever worked with. You can tell that he truly cares about his clients and his team and that's what makes ALL THE DIFFERENCE because they all go above and beyond to actually meet your needs rather than just trying to sell you on some high-end unit. We feel very lucky and thankful that we came across Joe and his team two years when one of our furnaces died during the middle of a horrible snowstorm. We had several companies try to overcharge us and up-sell us on more expensive units than we needed. Thankfully, Joe came out and provided us with an honest assessment of our needs and options and gave us an incredibly fair quote. His team installed the new furnace the next day! Since then, we've gone back to Polar Bear to replace our second furnace and both of our AC units (all were 15+ years old). Each and every time, Joe gave us an honest assessment, a fair quote, and his team always comes in and gets the job done without leaving a trace (even in the middle of a snow storm and the pouring rain, they even brought their own shoe covers). They are always considerate and stand by their work! A huge shout out to Edwin, Rodolfo, John, Angel, and the rest of the team for such amazing work. Our only wish is that Polar Bear provided other home services because it's difficult to find such trustworthy companies/contractors in DC. We will always use Polar Bear for our HVAC needs and would highly recommend them for yours, too!"

"We left for vacation the Tuesday before Thanksgiving only to find out from our neighbors that gas was leaking from our recently deceased furnace.  Our contact Tsengel sent Kevin P.to give a quote. We received two quotes from contractors we used in the past and the Cyprus quote was $1,000 less than the other quote.  They scheduled and installed the new furnace on December 4 by Jonathan R. and Steven C.  All four staff were great and we are happy with the results.

"September 2019, my water heater broke and TC HVAC Services replaced it with a new water heater. And they also fixed my AC and fridge. Recently, in October 2019, TC HVAC Services installed a new humidifier in my home. Mr. Thea Chea, the specialist was professional, honest, and he answered all of my questions. The repairs and installation were completed in a timely manner. And costs were reasonable and fair. I would definitely use TC HVAC Services again and I have recommended TC HVAC Services to my family and friends. Thank you, Mr. Chea and TC HVAC Services LLC."

"On time and very nice! They surveyed the existing gas fired boiler system (very old) and determined it was still in working order. There was no pressure to redo the entire system, I actually had to ask for a budget on replacing it. We signed an annual maintenance contract with them for the HVAC system and look forward to continuing to work with them."

"John, the tech, was patient and thorough as he cleaned and took readings of the system. He took the time to show me what was actually needed to update my furnace and make it work efficiently. Plus my dog really liked John too."

FAQs for furnace / forced air heating system install or replace projects in Fairfax, 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.
