"Angel was informative and quick! Our AC was on our roof, so he needed to use a ladder to climb up. We were out of the new R-22 freon, He showed us the gauge and gave us additional information with pictures about issues with the way our duct work was installed to make sure that we didn't lose efficiency when we got things repaired."

"The two person crew arrived on time and installed the heat pump out in the rain under a 10' pop up tent and replaced the air handler. The whole job was complete before the end of the day."

"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."

"The team arrived with A/C units that were the wrong size. To their credit, they were able to locate the right sized units and have them delivered to the house. I did have to re-sign quote paperwork though and I ended up having to pay more than what was originally quoted even though it wasn't my fault that wrong sized systems showed up. It wasn't alot more, but still. The install crew worked really hard and got the systems installed that same day and it is working much better than the old system which was on its last legs. However, I had asked them if they checked the airflow in each room and was told that the airflow in each room was good. I had also told the crew about a broken ceiling vent in my son's room and was told it would be looked at and fixed. After the crew left and the A/C came on, I went room to room to check the airflow coming from the vents and that's when I discovered that there is very little air coming from the vent in my uppermost bedroom and in both vents in the living room. I contacted my point of contact (POC) at McCrea about this situation and he told me that we are waiting on a response from the installation manager - that was 3 days ago. Also, I was told that the financing paperwork that the crew gave me to sign was all that I needed to do and McCrea would take care of the rest. However, the day after the install, I was contacted and told that I needed to go to their website and fill out a form for financing. When I told the POC about it he was like, "Yeah, go to the website and fill out the form". No apologies for the miscommunication or anything. The positive is that the installation crew was professional and worked really hard to get both systems installed in a shortened time frame due to the snafu with having wrong sized equipment. Negatives - (1) The miscommunication about the financing paperwork (2) The installation crew showing up with the wrong sized units (not their fault) (3) The vent still broken in the one room and (4) Insufficient airflow in some rooms. (5) Having to pay more for a mistake that McCrea made. Still waiting on an answer from McCrea as to if they are going to fix any of these issues. I'm happy to update this review if McCrea resolves outstanding issues satisfactorily."

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"JDL HVAC Services was the contractor provided by our home warranty company to repair our heating system. The were initially prompt and came out to the house and attempted to diagnose the problem. The technician though the problem was the circuit board and JDL delivered a replacement from Carrier the same day. Unfortunately, the part did not fix the problem and the technician thought the replacement part was defective. Unfortunately, it was Friday and Carrier wasn't open on the weekend. I specifically asked the technician what would happen on Monday and was told that JDL would get a new part Monday morning and then come to the house immediately to install it. This was very important since we had no heat on Friday and over the weekend and the temperature dropped below 20 degrees at night. Monday was a disaster. Unknown by us, JDL called at 7:30 a.m. and when we didn't answer, they removed us from their schedule. At 8:30, we realized they'd called, and contacted Joe and he added us back to the schedule, but in the afternoon. When a new (more experienced) technician showed up, he did NOT bring any replacement parts. When I called Joe to inquiry why the technician had no parts with him as promised Friday, he said he wouldn't buy another part because he couldn't get a refund on the first replacement circuit board. He also wasn't convinced the heater circuit board was the problem and wanted to do more diagnostics. I also asked Joe why they didn't come out in the morning as originally promised, and he had the audacity to blame us for not answering his phone call which we had no idea to expect. He also blamed his technician for providing us incorrect information. He did put another employee on standby to get parts from Carrier once the new diagnosis was complete. The new technician found another part that had failed and it was delivered with the original replacement circuit board. Both replacement parts were installed. While the technicians were friendly and informative, Joe was rude and lacked friendly or acceptable customer service skills/friendly. He also does not keep his technicians informed (the new technicians couldn't answer any of my questions) and it did not appear the technicians speak to each other when they transfer a repair. Overall this was not a positive experience due to the poor customer service from Joe. He did call an apologize (left a voicemail) after the repair was complete."

"I hired JC Flood to fix my hot water heater. They popped over for a quick appointment and our hot water heater worked for a few days before dying again. JC Flood explained the hot water needed to be replaced. They were excellent about including proposals for replacement units. Very much appreciated!"

"To whom it may concern,      I wanted to say how much I appreciate Davy and Seth coming out to inspect my furance. They were able to tell me exactly what is wrong with the system. How it was originally installed wrong, showed me the mold that is growing inside of the system. They removed a return vent jerry rigged filter that I did not know existed. They were extremely helpful and made sure that I understood all the problems that are wrong with the system. When i asked them if they could spray down with lysol before entering the home due to my grandfather's health issues they did it with out making a fuss, and did so everytime they reentered the house. They were extremely professional and knowledgeable."

FAQs for ducts & vents installation and replacement projects in Ashburn, VA

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
