"Great company. I am very pleased with the installation of the replacement gas furnace, digital WiFi thermostat, filter system, and water safety package with drain pan. The technicians, office personnel and owner were very knowledgeable. Very courteous, answered questions I had on the new furnace by Amana. Also very pleased with the maintenance of the other HVAC system installed at my house. Will recommend them to my friends."

"Kamal diagnosed and completely repaired a failure with our upstairs ac/heat pump that was having high/low stage lockouts. Neither the ac or heat pump was working. He replaced the compressor which had died, replaced the TX valve in the attic, which was installed incorrectly by the original installer, flushed the line and checked for leaks, etc. In a quick turnaround time. Kamal communicated every step of his repair and was very honest and responsive. Everything is now working perfectly. This is a complicated system to repair, and the expertise, timeliness and the VERY fair price Kamal gave to us made it a First Class job. Great work!"

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"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."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"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."

"Everything went well!  They did accidentally bring the wrong equipment at first because of a paperwork mixup at the home office, but they corrected it quickly and even upgraded my outdoor heat pump unit as compensation for the mistake.  That did cause them to have to drive to the Lennox distribution center and back, setting the install completion back a couple of hours.  I guess for that I have to knock them on "quality".
But other than that, everything went smoothly.  They were professional and courteous.  They also called back the next day to check on everything and make sure that everything was satisfactory and to apologize for the mixup.
Thanks, Modern Mech!

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