We pushed off the replacement thinking our unit would survive one more winter, but of course of furnace went out unexpectedly in the middle of the night during one of the coldest stints of the season. Called Residential Express the following morning, they pulled up my quote from 4 months prior, verified the price hadn't changed and were able to schedule me for a full HVAC replacement the next day. Freddie and Flavian arrived on time and were very professional moving through our house and working in our backyard and utility closet. They explained any changes they needed to make, went over the new setup and recommended service intervals, and hauled all of the old equipment away, leaving our house looking better than when they arrived. Very happy with our experience with Residential Express and wouldn't hesitate to use them again.

Absolutely outstanding service from C.D. Shanahan's. Armando, Juan, and Elijah were incredible!…read moreArmando and Juan from C.D. Shanahan's HVAC, Plumbing, Electrical & Remodeling LLC came out right before an impending severe snowstorm and worked in sub-15° weather from 8 AM to 8 PM to uninstall our broken Heat Pump and Air Handler and replace them with a brand new Heat Pump and Air Handler. Simply put: these guys were the best. Incredibly professional, hardworking, and dedicated from start to finish. They didn't rush a single step. They also helped install a new thermostat, made sure everything was running smoothly, and ran all the necessary tests to ensure the system was operating perfectly before they left. Huge shoutout to Elijah as well!. He took the time to explain everything in detail about the humidifier, thermostat, and Air Handler, and gave us genuinely valuable maintenance tips that made us feel confident moving forward. C.D. Shanahan is probably the best HVAC company you've never heard of. If you want a team that shows up, works hard, communicates clearly, and takes real pride in doing the job right. Highly recommend.

I'm updating my review to cover my experience having FH Furr replace an existing HVAC system in my…read moreDistrict of Columbia condo. This review focuses on the installation team's workmanship, issues encountered, and the company's responses--or lack thereof--when addressing these problems. Generally, their technicians have been helpful, which is why I rated them two stars; however, service quality varies depending on who you get. The main concern lies with the quality of installation. I chose FH Furr to install a new unit in January 2025, after sales representative Mike Miyasato quoted me and assured all work would meet code and FH Furr standards. They even provided a "Guarantee" certificate outlining warranties, and an install manager (whose name I don't know) assessed the project and confirmed the quote--which, in hindsight, was likely for a unit larger than necessary for my space. That mistake was partly mine, but not the focus here. The installation team, led by Xuan Pham, completed the job in one day but left my bathroom--the only one in the condo and where the air handler is located--in a messy state. It seemed they made no effort to clean up debris or drywall dust. While I don't have a photo of the initial mess, photos attached show what they left behind in the ceiling. I had to clean up myself so my pregnant wife and I could use the bathroom. The next day, contractor Robert "Lee" Cramer handled the drywall and painting but left a large hole near the return vent and failed to paint the ceiling, as seen in attached photo. He said his task was only to "prepare for paint," even though the invoice included both drywall and painting. I ended up buying supplies and painting the ceiling myself. About a month after installation, in late February 2025, another problem arose that required technician Kevin Pineda's assistance. According to the invoice, he found the disconnect wasn't fully inserted, preventing the outdoor unit from running. Once fixed, the system worked properly. By May 2025, as the weather warmed, condensate from the unit exposed further installation flaws: the drain pan leaked because it wasn't properly leveled and lacked a float switch. Both issues are documented in the invoice excerpt shown in attached photo. I later learned a float switch is required by code and standard practice when installing a unit above living spaces. To prevent damage, I set out a bowl to catch leaks and requested service. Technician James 'Ruffin' Price diagnosed the issue and escalated it to management. I was told repairs would come quickly. Documentation of these findings is in photos attached. Soon, an install team member returned and insisted the drain pan was fine, dismissing the prior technician's concerns. On June 6, 2025 contractor Mihaita Morovan repaired and painted the damaged drywall (photo attached). Unfortunately, the problems didn't stop there. Less than a month later, as summer temperatures increased, the unit began leaking heavily again, resulting in multiple wet spots and visible mold growth on the ceiling. It took several calls--and even a legal threat--to finally get a response. Technician Thomas Edwards came out, listened to my concerns, properly fixed the drain pan, and wrote up a detailed report while promising to escalate the issue at their quality control meeting. His documentation and related photos are attached. Within weeks, another contractor repainted the water-damaged ceiling but didn't remove all the ruined drywall, so paint soon peeled and chipped. I eventually completed the repairs myself and am relieved the unit has caused no further harm to my condo. Overall, this experience did not match the warranties and guarantees FH Furr promised. The countless hours spent contacting the company and missing work for technician visits hurt my family financially. This ordeal has left me unwilling to use their Gold Preferred Partner Plan for maintenance, even though it was part of my contract. At this point, I want nothing more to do with FH Furr, and I cannot recommend their services.

So, I first want to start off by saying that every single technician/expert that has provided…read moreservice to us has been FANTASTIC! Fullstop. This review is based on recent experiences with customer service representatives/admin folks. So it was during calls to the main number, and we reside in Virginia. We recently had a very expensive repair for a hot water heater that severely damaged our circuit breaker box. So the techs came out, did their thing and were phenomenal. However, in order for us to submit the repairs for reimbursement with our home warranty company, we require an itemized invoice. As per the egregiously rude phone reps we have encountered, there is a company policy against itemized invoices. Like, WHAT!?! I have never experienced anything like it in the history of working with service providers. There is always an itemized invoice. However, that in itself is not the issue. First, my spouse spoke to someone who said that it is only possible to obtain by escalating to a manager. So we waited and attempted to follow-up. Each time after we both tried to follow-up, we encountered some of the rudest, most unprofessional individuals on the line. Not to mention, AGAIN, how does it make sense that you are doing work of this magnitude and cannot produce an invoice that breaks down parts and labor!?! I am certain that this isn't the first time in history that the company encountered this kind of request when customers are dealing with insurances and warranty companies. It is wholly disappointing, when you consider that the individuals in the field doing the labor intensive work can be overshadowed by the policies of the company. I literally have no idea what to say at this point, but that we will be transitioning to Michael & Son's or another provider. Because who wants to pay this kind of money to be mistreated on the backend for something as simple as an itemized invoice. Such a shame!

John came out and was very straight forward and up front with everything he did. He explained the issue to me, how he would fix it, and even provided some recommendations I may want to do in the future. My second time I used Bluestar was on a Sunday and they are closed on Sunday's. I did not realize this at first and left them a voicemail in the morning. Realizing they were closed I called another company who would have charged me more than Bluestar to come out later that afternoon to look at the problem which was that my Nest Thermostat was giving an E73 error code meaning it was not getting power. To my surprise I received a call from John at Bluestar that afternoon prior to the other HVAC company coming out. I discussed my thermostat issue not getting power with John and he suggested several troubleshooting fixes I could try over the phone. After eliminating several causes of what the problem may be John suggested holding down the front panel cover switch to the unit to see if a power light was coming on. In doing this I noticed sometimes the light would come on and sometimes it would not. There seemed to be a loose connection in the a wire that was causing the switch not to supply power. After playing with the switch for a few minutes I got the power to stay on and the problem was fixed. John solved my problem and saved me a good deal of money as I canceled my appointment with the other HVAC company. John took over 20 minutes talking to me on the phone going above an beyond to help me solve my AC issue on the day the company is closed. I would highly recommend BluStar to anyone and will use them for all my future HVAC needs.
