I had a plumbing issue that was starting to stress me out, and from the first phone call, I felt like I was dealing with professionals who genuinely cared about helping -- not just booking another job. They responded quickly and showed up right on time, which already put them ahead of a lot of contractors I've dealt with before. The technician was respectful, knowledgeable, and took the time to actually explain what was going on instead of just throwing out technical terms. I really appreciated that. It made me feel informed and confident about the repair. What stood out most to me was the honesty. There was no pressure to upsell anything unnecessary. They focused on fixing the actual problem and making sure it wouldn't turn into something bigger down the road. The pricing was clear and fair, and there were no surprise charges at the end. The work itself was done efficiently and with obvious attention to detail. Everything was cleaned up afterward, and you honestly wouldn't even know work had been done -- except that the issue was completely resolved. It's hard to find reliable service companies these days, but Crown Plumber exceeded my expectations. If you're in Ashburn and need plumbing work done right the first time, I wouldn't hesitate to call them again. Definitely five-star service in my book.

I am a disabled senior. This review documents objective facts regarding HVAC services provided by…read moreBluestar Air Mechanical Inc. across two of my properties, identifying the specific staff involved. Alexandria Multi-Level Townhome Installation Diagnostic Visit (Isaac): Technician Isaac condemned my original AC unit as completely "dead" immediately upon arrival, without opening the service panel or performing electrical or refrigerant pressure tests. Salvage vs. Installation (Walter? & Karol?): Walter and Karol? spent extensive time meticulously extracting the original unit intact to preserve all components, while spending minimal time securing and properly installing the replacement machine. Undersized Equipment: For my 1,830 sq. ft. multi-level loft townhome, Bluestar installed a 2.5-ton National Comfort Products through-the-wall AC unit that is physically less than half the size of my original machine, leaving massive voids around the wall opening. Life-Safety Fall Hazard: The machine sits near the roofline several stories above a ground-level driveway. It rests inside the oversized opening without dedicated structural framing, a properly fitted sleeve, or mechanical mounting brackets to anchor it. Massive Gaps & Exterior Visibility: Gaping openings were left on the sides, so wide that I can clearly see neighboring townhomes and direct outdoor daylight from inside my utility closet. Soft Foil Tape & Expanding Foam: The top of the machine was sealed with only soft silver foil tape and flexible wrap rather than a rigid sheet metal transition or structural collar. Into the open side voids, Karol? messily sprayed orange expanding foam instead of constructing proper framing, trim, or weatherproofing. Severe Noise & Vibration: When activated, the unit generates extreme operating noise and structural vibration felt throughout the living areas. Missing Property: A step stool kept in my utility room went missing immediately after the crew packed their gear and departed; I am continuing to check my home to ensure nothing else is missing. Communication Evasion: Karol? conversed easily in English upon arrival, but suddenly claimed not to understand English when questioned about the open gaps, lack of framing, and spray foam. Dismissive Management (Lyn): I sent Lyn multiple detailed text messages and photos documenting my serious safety concerns, questions about the oversized opening, and the complete lack of structural support. Despite being fully informed of the severity and specifics of the hazard, Lyn trivialized the issue before 8:07 am on Sep 16, only replying that she would send someone back merely to "clean that up," offering no plan for structural framing or proper sleeve installation. Washington, D.C. Property Service Undelivered Documentation (Isaac): I was charged a significantly higher inspection fee specifically contracted to include an official written cause-of-damage report and a formal repair estimate for an insurance claim. Technician Isaac completed the on-site visit, but no written report or cost estimate was ever provided, despite multiple follow-up requests sent directly to both Lyn and Isaac. Licensing Verification: Bluestar explicitly confirmed prior to the appointment that the technician held a D.C. HVAC license, but no license number or proof of licensure was ever furnished. Based on these documented facts, I cannot recommend Bluestar Air Mechanical Inc. to other homeowners or seniors.

Continue reading if you'd like to know about my experience. Well, one day of my nightmares came true... it was a blazing hot summer day and my AC was no longer blowing cool air. A few days went by having a few contractors come by and give an estimate to replace my unit (I had a leak and my refrigerant phased out). Some companies were able to install the next day but it was so expensive! Or some contractors were cheaper but I had to wait 3-5 days for installation... Soooo being the Goldilocks of this HVAC issue, I went on google and yelp again and found One Hour Heating and Air. I quickly and easily booked an appointment for an estimate. They were able to accommodate me the next morning. They were fantastic! They communicated that JT would be arriving at 9am. JT showed up early! He was very professional and put on those shoe booties, so the floors don't get dirty. (Being an Asian household, we thank you!) JT was knowledgeable of the products and my neighborhood community. This was very comforting. Also, he was really willing to work with us and wasn't pushy at all! A few hours later, we decided to go with One Hour Heating and Air. They were able to schedule the installation for the next day! The day of installation, I received a text that my technician was on his way and sent a picture of what he looked like. (That was amazing! I would like to know who I am letting into my home.) Anyways, Daniel was the main technician, and he was also very professional! I would say all went smoothly! Overall, the team was very hard working and did a fantastic job! Thank you so much! You all are sooo awesome and cool just like my AC :D --definitely recommend!
