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!

However, the mis-management of this company combined with the lack of attention to detail of the majority of technicians we've had out these past two years has led to repeated customer service failures. I've captured more detail details below if you want more than an overall summary rating. Be forewarned their technicians are nice, and at the end of the appointments, which may only be diagnostic and not actually the fix because they need to wait for parts and then to come back (which has been where the majority of our issues have been), they ask you to give them a five star review so the technician gets a $25 performance gift card, which skews overall service ratings. Most recently our 4 year old, warranty covered, HVAC broke again (4th time since a company bought out by FH Furr installed and FH Furr fixed 3x before). It happened on a Saturday night, and we called first thing Sunday morning. They told us the technician who had the part we needed was off that day so we had to schedule for later in the week. We were out of town 4 days, then the morning of our apt, 45 min into the arrival window, we got a call saying the technician has the wrong motor, they will have to order a new part, and then when they get it in a few days they will call to reschedule. This our final straw but keep reading for more history. Something just like that happened before on our HVAC. But in that case they ordered the wrong part so we had to wait for the first part to come in, then wait for the right part to come in. During another HVAC fix they identified an issue, ordered a new part, installed it, then ID'd a second issue. I appreciated that the technician was forth coming that they should have caught that during the first diagnostic call and apologized we would have to wait for a part again. The fact that they took ownership would have made this fully forgivable if we didn't have so many other issues. They also ordered a part for a fix that was supposed to come in in a few days but I called a week later and it still hadn't come in. I called 4-5 days in a row, then finally I asked to speak to a manager and they said they can use a different, universal part instead of continuing to wait. It wasn't clear why there was such a huge difference from when the first technician said the original part would come in vs the actual timeline, but I suspect based on some of my first calls that the part might not have been ordered at all until I first called to check on it. We had a toilet not fully flushing upstairs and they quoted us $200 to fix it, but recommended the toilet itself may continue to have problems because of the design unless we replace the whole thing, so we should consider that long term. After half an hour on YouTube, and an $8 part from the local hardware store, my husband was able to fix it himself and we haven't had an issue again in the last 6 or 7 months since that issue. A theme you may pick up on is how often I have had to call them for follow up. Some of the technicians will admit that if you don't hear by xx day from dispatch, you should call them and ask if your parts have come in yet. We have definitely found that to be true on both HVAC and toilet calls. In our experience it could also be hours before a manager calls you back if you ask to speak to one. We bought the maintenance membership so we have tried to make this work, but at this point I can't waste anymore time micro managing nor can we rely on them to be responsive or do a job right. Save yourself the stress and money, avoid this company.

I'm leaving a review based on my prior experiences with KCS (have used them since we purchased our…read morehome in 2020). We got their base maintenance plan with 2 inspection services each year, and used that for about 3 years (no real issues to fix.) During one inspection in 2024, the tech realized that our furnace water pan had filled (but not so high it shut off yet) and he helped identify the problem and luckily was able to fix it the same day (no parts/ charge.) He suggested in a non-pushy way that it really may benefit us to up our plan to the higher one (almost double the cost/yr, so a little scary) because we're probably entering the zone where larger repairs may start for our furnace and the plan covered most of the types of parts that would be in a significant repair. He seemed knowledgeable and trustworthy, so we decided to at least do it for a year. We were very lucky, because the next year was the epic winter - the furnace went out/ our YouTube tricks didn't get it running, and the red plan ($500/yr) meant we pushed to the top of the queue and got someone out when the temp was dropping in the whole house. Apparently the part needed to fix it was over $1,000 (not including install), and that was covered in our plan. So that proved the value for us! I know they were recently acquired/ merged with FH Furr, so it appeared that our online requests for service on the KCS site were not actually being seen/ addressed. When I got time to call over, the former red maintenance plan was unfortunately no longer sold by this new company. I got the "gold plan" which includes 2 HVAC inspections, a plumbing inspection, and an electrical inspection for honestly a price that is so cheap I'm worried it's going to be an upselling scam :/ so I'll update this as needed in the future to help others who may wondering if this new company will have the same service quality as pre-acquisition.

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.
