    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.

    Good experience and customer service. My AC had been knocked out last week by the storm the night…read morebefore and was able to arrange an appointment in a reasonable amount of time, Tech arrived on time, and it turned out the issue was just a safety switch on the electrical plug associated with the AC unit. So I just paid for the diagnostic fee. Was impressed with their professionalism.

    This is my second time using BlueStar and I have nothing but amazing things to say about them. The…read morefirst time they fixed my furnace which had build up on a sensor which was an easy fix. 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.

    My AC suddenly stopped working yesterday. I checked the AC compressor unit outside my condo and…read morenoticed it wasn't turning on when I switched on the AC. I called BlueStar and they were able to squeeze me in within a few hours. Isaac was able to diagnose the problem quickly and got my AC running. He was very professional and explained the issue. I've been BlueStar customer for several years and will continue to be one for their great service.

    I can't recommend TC HVAC Services enough. They quite literally may have saved my house from…read moreburning down. Thea, the owner / service manager, came out to inspect our AC system and immediately noticed something dangerous: the previous installer had set up the outdoor disconnect without a fuse, which is a major safety issue. Because of that, the wiring had burned and nearly made its way into the house. T patiently explained everything to me--what went wrong, why it was dangerous, and what the proper setup should be. He recommended replacing the disconnect with a fused version, and clearly laid out the potential risks and what to expect. When we turned the system back on, we were holding our breath... and to our relief, the 10-year-old compressor kicked on just fine. T could have easily told me I needed a whole new unit, but instead, he was honest, transparent, and incredibly knowledgeable. I even looked up everything he explained afterward--and it all checked out. By the way, the communication was excellent--I reached out through Yelp and was kept in the loop with email reminders and messaging right through the app. Everything felt smooth and professional from start to finish. In the attached photos, you can see the burnt wiring and connector from before, and the new fused disconnect they installed. The difference is night and day. If you want HVAC work done right, by people who take the time to do things safely and explain them clearly, TC HVAC Services is the team to call. I thought the cost for the service was very fair, and I'm really glad I found them.

    They were quick with a good quote, and arranged to come quickly. I am very satisfied.read more

    5/5 service! I…read morewould recommend this company to anyone who is in need of HVAC services. Big or small problem it is important to take care or it before the winter. My AC abruptly stopped working during the hottest month of the summer. I'm my house everyone works at home so it was important to get it fixed asap. I contacted a few companies that gave me quotes that had either contingencies or a few week wait. When I contacted Alex HVAC the quote that I received was very clear and an agent was dispatched to my house that same evening. The agent was very polite and professional. We had our AC back and running within few hours. I definitely recommend this company if you are looking for quality work and reliable price.

    Alex is not the ultimate professional you say he is. His company installed an ac unit in my roof…read moreand installed it very poorly and will not answer calls and text to get it corrected. He installed and industrial sized AC and heating unit on my roof inappropriately and now I have roofing damage which I'm asking him to come make the correction and he will not respond. If you are looking for installation on your roof, stay away from this company because they do not keep their promise. In the videos, you can see that they dropped it directly on my roof and now it's starting to leak. I would never hire this company again and you should be careful. I see that he is reading my text messages but not responding so that means he doesn't want to come and finish what he messed up. Disappointing.
