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.

Shortly after, I had an urgent need at our single-family home to inspect the system and rebalance airflow. I spoke with Dan (the owner), and it was genuinely refreshing to deal with someone who clearly cares and takes pride in the work. Dan sent Mike out, and Mike was fantastic--easy to talk to, knowledgeable, and he got everything dialed in. I even learned we have three dampers I didn't know existed. ‍ It's a real pleasure working with a company that's owner-run and service-focused--not the private-equity "roll-up" model where the goal is volume and upsells.

My 10-year old PTAC (Packaged Terminal Air Conditioner) unit in my sunroom was displaying an error…read morecode and was not producing cool air. The technician evaluated the problem and concluded the compressor was not working and provided a couple of options. We proceeded to replace the existing unit because it was near its end of life and replacing the compressor would not be cost effective in the long term. Air Treatment Heating & Cooling was able to replace the entire unit during the peak summer season within a couple of days. From start to finish, personnel was friendly, professional, and installed the new unit with no problems. We will definitely use Air Treatment Heating & Cooling in the future, and would recommend their services to others as well!

I had asked another company to diagnose the problem and they said that they tried to fix it but it would not cool and I needed a whole new system. Mason came out and carefully diagnosed the problem, offered a solution and then fixed the outside unit. We trust Mason and his careful attention to detail. We look forward to him and his coworkers taking care of our HVAC system as long as they can keep it going. We are so grateful to have a house that is cooling off. We will definitely be asking for their support and assistance for regular maintenance and for any additional HVAC needs. My husband and I are super impressed with Mason and Meade's Heating and Air.

I highly recommend using T&T Associates for any kind of HVAC services. I was always skeptical about tune up service providers as they would come up with unknown surprise problems to add up more on final invoices, particularly those big annual service contract providers that would end up costing several times more than if you would not bother having them. I used to have an annual service contract with a larger well known company that I fired after their technician tried to sell me a new water heater when a prior owner replaced the unit just a couple years before that with them. He did not even bother to check before trying to fool the new homeowner. Fahan with T&T Associates proved that there were still honest service providers out there. I wish we had more like T&T Associates.

A service technician from Air Master Heating and Cooling LLC visited our home on June 12 and informed my husband that our furnace/AC issue could be repaired. However, it is now June 24 and no one has returned to complete the repair. Nearly two weeks later, we are still waiting with no resolution and no meaningful communication or follow-up. As first-time customers, this experience has been very disappointing. We have two young children, and during this time we have been dealing with an uncomfortably hot home while waiting for the promised repair. Unfortunately, the lack of communication and follow-through has made this a frustrating and unprofessional experience

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.
