BlueStar Air Mechanical is a call away for your repair, maintenance and installation needs. We specialize in fixing and tuning up cooling, heating and plumbing systems for both residential homes and commercial establishments.
"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 dude shows up on time, 5/5 on that. Leaves 10 minutes later without saying a word. I message him 3 hours later asking if we were still doing the job. 2 hours after that he messaged back saying he had his helpers cancel and we need to reschedule. I ask when he's thinking we can get it done. 3 days later I haven't heard back. I open a new project on Angi, and re-select this same guy by mistake. He replies promptly, gets all the details, and then once he gets my email no further contact. It feels like there's something personal here, or maybe he quoted too low for the project, but in any case I literally cannot imagine a less professional way of handling this whole situation. My guess is that he showed up to the job to scope it out, then went to find a couple day laborers to actually do the work. Maybe he couldn't find any, maybe he realized that this job was too big. In either case, just say so. Jesus."

For all inquiries, please call or text (703) 281-4185. Will not respond to emails or messages through the message center. We have been serving Northern Virginia since 1992. We have Virginia class B license for projects up to $120,000, but will do virtually any project or repair inside you home. We do have a $175 minimum house call fee that includes the first hour of work. After that it is $75 per hour fee for smaller projects. Larger projects are based on a lower hourly rate which is included in the over all project estimate. The cost is generally determined by the job but some areas such as exterior carpentry may be billed hourly due to the unpredictable nature of the work. We may find more work up close or underneath visibly damaged areas. All employees speak English well. We are also able to communicate in Spanish, Cechua or Italian (just in case). We are covered by general liability insurance, disability insurance, workers comp, and heath insurance. I treat my employees and my customers, in the same manner I wish to be treated myself. We have been Angies list supper service award winners for the past 11 years. We care about our workmanship and our customers and I think that is reflected in our awards. Thank you for considering us for your projects.
"Will and his team are knowledgeable and responsive, a trusted contractor! He resolved several plumbing issues and replaced smoke detectors throughout the house."

Central humidifier installations and replacements FAQs
Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
