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.

I wanted a second opinion and Trademasters checked my system recharged it with dye to look for leaks and it lasted past when i sold the house 6 years later. This time American Home Shield was supposed to take care of my a/c and they sent out a crooked technician to install the cheapest crappy equipment and i would pay 95% of this repair so i would not let them touch my house. I decided to ensure my home was repaired correctly so i contacted Dave's team at Trademasters. Shane came over and gave me an estimate for my a/c system . Everything went as described and I am so happy with my new system. These guys are great !! They are honest and trustworthy and its hard to find honest technicians this talented in the HVAC industry. Keep up the good work !!

He did just that and while he ended up coming a bit later than estimated, he kept me in the loop and arrived when he said he would. Edward was polite and straightforward about the price and was done in less than an hour. I was impressed and had them (Edward again) come back three days later for some non-urgent work. Same great work/service. Will definitely use them again.

The installation guys were also very nice and did a great job, It's only been a few days so the system is running fine. The only gripe is that they left a lot of trash and residual foil and scrap pieces of the old ac up there. It was a pretty tidy space so it was noticeable and a little disappointed that they would leave parts and trash up there. I would say give them a call for service or new installation, but ask them to remove any trash and leave the place somewhat cleaned up. You pay a lot of money to replace a whole system and to find the space messy left a poor taste. It could've been an excellent service, but an oversight in minor details made it mediocre.

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.

Scheduling was easy and was done directly through the Yelp app. On the day of service, Brice and TJ arrived on time, wore shoe covers inside the house, and walked through the work order. They were done with our duct cleaning in about 2 hours. I requested an additional, same-day service and they were able to accommodate our dryer vent cleaning at the same time. I consider Residential Express's service to be good quality and good value. They were particularly courteous of our pets and reminded us there was a discount coupon available on their website! We currently have an annual HVAC contract with a larger company we are unhappy with. Residential Express Heating & Air offers personalized service and are definitely considering switching our annual HVAC service contract. Thanks again for helping us take care of our home. I highly recommend sending Residential Express a message about your next HVAC project!

Matt provided outstanding service throughout what turned out to be a very unusual situation with my…read morewater heater. He installed a brand-new water heater, and when it appeared there was still an issue, he went above and beyond by replacing it a second time to make sure the problem wasn't with the unit itself. Ultimately, we discovered that the real issue was an electrical problem with my circuit breaker, not the water heaters. What impressed me most was Matt's honesty, professionalism, and commitment to helping me get the issue resolved. Even after determining the problem was electrical, he worked with me on pricing and generously discounted his services so I could put those savings toward getting the breaker repaired. It's rare to find someone who genuinely prioritizes helping the customer over simply completing a job. Matt was responsive, knowledgeable, and incredibly fair throughout the entire process. I highly recommend him and his company to anyone in need of plumbing or water heater services.
