Was pleased with the…read moreexperience, which simply involved taking measurements and asking what changes I might want with the setup--much better than the high-pressure sales pitch from the bigger companies in the area. 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.

RES installed new HVAC in September 2021. Freezing temps last night and my heat wouldn't kick on…read more Needless to say, it's cold in the house. Literally wearing a sweater and two sweater wraps. New HVAC filter, reset breaker. Thermostat batteries are fine. Still not kicking on. Sent Yelp message to RES because they have always been quick to respond. And they did this time as well and the woman who gave me a call was nice and tried to help. Pretty disappointed that they can't quickly swing by today. From what I've read, it's likely a dirty flame sensor or the ignitor switch (neither of which is a long job - I just don't have the tools). HVAC less than 5 years old, so parts are under warranty with RES; however, I had to call someone else. Bottom line: Someone else is coming today, but I could end up paying for parts. Kind of feels like my current needs weren't lucrative enough for RES to make a concerted effort to swing by.

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.

FH Furr's biggest problem is not their technicians--it's their management's complete lack of…read morefollow-through. I'm attaching the emails I sent to FH Furr regarding the second incident. They are exactly what was sent, with my email address, phone number, and home address redacted. The first issue with my new HVAC system required 4-5 service visits over multiple days before it was resolved. After the issue was resolved, I repeatedly asked about FH Furr's advertised $500 No Frustration Guarantee. I never received a callback or any type of explanation--they simply ignored it. The second incident was even more frustrating. After my service request had already been pending for over 24 hours, my appointment was pushed back another five days during a heat wave because a specific technician was apparently needed. I called back to ask if another technician could be sent sooner because waiting five more days was not acceptable with 95+ degree temperatures and the upstairs reaching around 80 degrees with two young kids. At the same time, I asked that a manager contact me to discuss my concerns with how the situation had been handled up to that point. I was repeatedly told someone would call me back (twice by phone and once through a technician), but nobody ever did. I followed up with two detailed emails to document the issue and give FH Furr the opportunity to handle it, including asking again about the $500 No Frustration Guarantee. Those have also gone unanswered. If you end up with an issue requiring anything beyond dispatching a technician, don't expect management to follow through. At this point, their $500 No Frustration Guarantee feels more like a sales promise they have no intention of honoring. Every technician who came to my home was professional and did everything they could to help. They are not the reason for this review. This review is entirely about FH Furr's management and customer service. I will only be contacting them for future HVAC repairs while the warranty on their installation remains active--and only because I have little choice.

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.
