They went above and beyond to get our gas lines fixed and ensure our water and gas lines were properly bonded after lightning caused extensive damage to our home and gas lines. A special shoutout to James Jordan for going out of his way to make sure everything was clearly communicated and completed in a timely manner. His attention to detail and commitment to keeping us informed throughout the entire process and getting the project completed even when dealing with multiple issues were greatly appreciated. He made sure we had the key people from his team assigned to this project. We also want to give a huge thank you to Mike Kriesten and John Lambert. They worked an incredibly long day and well into the night, then came back first thing the next morning to finish the installation of our new gas lines. Their hard work, professionalism, and dedication to getting the job done meant more to our family than we can express. When you're dealing with something as important as your home's gas and water systems, having people who genuinely care about doing the job right makes all the difference. My family and I can't thank James, Mike, John, and the entire Marines Service Co. team enough. Exceptional service, communication, and dedication from start to finish. We are incredibly grateful and would highly recommend Marines Service Co.!

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.

Zach was personable, knowledgeable, and professional from the moment he arrived. He took the time to thoroughly assess the issue, explain his findings in a way we could understand, and provided honest, practical guidance without any pressure. One detail that really stood out was that he put on boot covers before entering our home. My wife especially appreciated that level of respect and care for our home. If you're looking for a plumbing company that values professionalism, customer service, and expertise, we highly recommend DB's Plumbing. Thank you, Zach, for an outstanding experience!

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!

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.
