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.

Called Friday morning and the receptionist was amazing and got someone to our house that morning. Full diagnostic told us the compressor went bad. Our unit was 13 years old, so it was about time for a new system. We decided to replace whole system as replacing a compressor is quite expensive basically half the cost of a new one. Mike came that night to price out a new system. I got two quotes from other companies. But decided on Shanahan because of their reputation, service as well as pricing. Talked with Mike and Conner (the owner) about our options and they came on a Saturday to install even though they didn't have an opening until Thursday. The owner himself came with a couple guys and replaced our system. They were very polite, did excellent work and we were back up and running. Plus they had very affordable pricing. These guys care! Use 'em. We loved our experience from start to finish!

It can be difficult to find honest and reliable HVAC companies, but this experience stood out. I had several questions prepared about my refrigerant, capacitor, and overall system, but I found that I did not even need to ask them because Jerry naturally addressed those topics during our conversation and explained everything clearly. He also completed a detailed inspection of my HVAC closet and offered a helpful recommendation for a better filter. The service was straightforward, with a flat fee and no upselling or pressure, which I really appreciated. Overall, it was a great experience, and I will definitely be using Cold Comfort again for my annual maintenance.

Our AC went out a little over a week ago, of course it happened toward the end of the week so it…read morewas Friday afternoon by the time we realized it wasn't something routine maintenance on our side would fix. Jary (who helped us when we first moved in) came out on Tuesday and said we had a leak somewhere since the closed-system unit was totally out of coolant. He came back Weds. to do the leak detection and found the leak, recommended a new coil. We had the new coil installed on Friday; this time it was Ricardo and team that did the work installing the coil. They did a great job and a couple hours later our house was back to normal temperature. Gabriel helped us with all the coordination and estimates and seeing if the part was still under warranty (it wasn't, but I didn't expect it would be honestly.) No one likes spending a bunch of money on repairs but I'm very confident that the recommendations Jary made were sound and correct. He did not attempt to upsell me at all, which is greatly appreciated. (The estimates Gabriel sent did include options for replacing the unit, but that wasn't necessary at this time and there was no pressure to do so.) I will continue to call them if we have issues in future with our HVAC system.

I had several additional requests which they accommodated such as adding an extra drain line and additional return vent and all the work was done as requested. Since completion of the job, they have come back on routine maintenance visits to keep the system up and running and the cost of which was included with the original work. I therefore. have been very pleased with after-installation service. Separately, I used them for plumbing, specifically replacing a sink faucet, repairing a garbage disposal, and repairing a leaky shower fixture. I was very pleased with this service as well. Especially the garbage disposal because all it needed was a minor turn of a crank to loosen it up instead of a full replacement, which saved me a significant amount of money. Obviously, overall, I'm very happy with their services. I will be using them again and highly recommend.

It's unbelievable but some companies required upfront deposit even before assessment of the issue. Our technician,Brian,was on time,called prior,came with shoe covers,quickly identified problems with toilet,gave us estimates and couple options to think about. I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb. Can't deduct star for high prices,because they are using gas and supplies which are horrible now.

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.

The main problem and downside is that they are very expensive and overcharge. Despite the Yelp page saying that the company provides a "free estimate", I was quoted $49 for the technician to travel. In addition, if I had not chosen to go ahead with the repair, the company would have charged me an additional $150 diagnostic fee. Essentially, despite the yelp profile stating a "free estimate", it will cost you closer to $200 to get a quote. I see this as false advertisement. In addition, when the technician concluded that the problem was the capacitor, I received a final quote of $600. When I googled the price of the same capacitor online, the price range was in between 75$ - 150$. Essentially, they are charging a premium of at least $450 per replacement for a single part (capacitor). Despite their professionalism and quality work, I do not recommend this company for the reasons stated above. If price is not a concern for you, and you would rather pay twice the market value for a job then you should definitely choose them. EDIT: I actually googled the price of a capacitor and offered to buy my own. I was told that by the technician that if I purchased my own capacitor that the company would not install it. In conclusion, they did not address any of my concerns. Unfortunately, after reading the other bad reviews, there seems to be a consistent pattern of discrepancies between what they tell customers and what they instruct technicians to say on site. Making an honest living is so much more rewarding than making it dishonest living.
