"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"

"This guy is young and has that techie cutting edge experience. He came in recognizing my problem immediately. He split my AC system to function on multiple levels and I can choose a single level to cool or multiple levels. Not only did this improve my comfort at home, but reduced how long my unit ran during the blistering heat this summer ( remember my statement about cutting edge). Pricing was reasonable and very customer-oriented. Trust me, you want this guy who doesn t come into your home and start throwing big names around and speaking in tongues that = a ton of money. He doesn t try and take advantage of you if you re woman or not familiar with the overall DNA of heating and cooling system. Try em! You won t like this company. You ll love this company!"

"The only reason I did not give five stars is I thought the service call price of $89.00 was high compared to $59.00-$69.00 offers by most other companies. The technician was knowledgeable, friendly and diligent. He found the problem quickly and repaired it on the spot then recharged the system. I will call this company when I replace my system."

"I was lucky enough to have someone refer me to BlueStar Air Mechanical when my AC started acting up. The home warranty company confirmed that it was busted, but their mechanic was unreliable. After contacting a couple of other companies and having high quotes, I contacted Danny at BlueStar. The next morning (on a Saturday, nonetheless) I met Rhandel who quickly gave me a quote to replace my HVAC system (furnace and condenser). Rhandel was very nice and thoroughly explained my options. My home has two HVAC systems, so he also added a quote for the second system (which was on its last legs, too). The systems recommended were upgrades to what I had (increasing 1/2 ton on each system). To accommodate this, BlueStar included extra ductwork for me so that my house could accommodate. We met on a Saturday, agreed on a price on Monday, and everything was installed on a Thursday. They sent two crews and these guys worked hard for 12 hours straight to make sure both units were completed that day. I was very happy with their pricing and service. I have already recommended them to people I know in need of HVAC service. Pros: Pricing, options, promptness, service. Cons: 3% surcharge for credit cards"

"This is a contractor we all want to find, to hire someone that will not try to talk you int.o a new furnace when the thermostat just needs to be reprogrammed after replacing weak batteries. The service man tested a few electrical components on the furnace, and he concluded that the furnace was not the problem. His service call lasted less than an hour, I learned a few things, and the temperature is no longer 57 but a more comfortable 72."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

"The technician was on the job within a few hours. The system was diagnosed and fixed promptly. (As it turns out, the problem was not with the thermostat, but with a transformer governing the fan.) This was everything I expected."

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