"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"Mr. Bamford is an amazing gem. We have hired him repeatedly for different projects, and he ALWAYS goes above and beyond. Whether it's working over 15 hours straight to make sure we had hot water for the next morning, pricing out all of the alternatives to get us the best deal, or just popping by when we call to check out the issue and see what it will take, his service is above any provider I've ever worked with. I highly recommend him, and am grateful for the excellent service he provides."

"Darren, the Salesman, was extremely knowledgeable and helpful. Very low pressure sale tactics, but laid out all of the options for you. The crew came and finished installing a new heat pump and heat exchanger in a half day and then another individual returned the next day to install a new water heater. Great communication and attention to detail every step of the way! Would highly recommend!"

"Jeff is a true subject matter expert. With 30+ years in the industry he came quickly, was prepared, and handled the pressure switch without any delays. I cannot say enough good things about American Clear Water LLC. He was professional, kind, and courteous. He allowed me the opportunity to watch what he was doing and explained in layman's terms. He was fairly priced. I would recommend him to anyone asking for help. He is permanently saved in my phone and I will be calling this gentleman if any other issues arise. Thank you Jeff & American Clear Water LLC for everything."

"After several repairs over a couple of years we decided to replace our 14 year old central AC system with a new heat pump system. We got quotes from 3 companies, and decided to go with B.A.R. Appliances AC LLC based on past experience, extended warranty, and very competitive costs. The entire installation was efficient and professional. I found Henry and his staff a pleasure to deal with. They left me with a nice clean system and I would highly recommend B.A.R. Appliances AC LLC for any HVAC work. It's nice to have quality work done in this day and age!"

"I couldn't be happier. I received a quote from another company that we've used for years and something didn't seem right to me and I decided to get a second opinion. Mark came over and tested my water and explained several things to me (the other company said my water tank needed to be replaced, Mark told me my tank was fine). He also presented several options (I could fix the existing neutralizer or get a new one - the other company gave me a much higher quote to fix the dinosaur neutralizer they installed over 10 years ago. We decided to replace the system with a new one. Mark also included re-routing the exiting water, removed a filter and moved the neutralizer before our water heater, which the other company installed it after the water went through the water heater. The technician showed up an hour early (he called me to let me know, the weather got really bad in the afternoon - ice) and was amazing. He talked me through what he planned to do, was neat, checked all the toilets prior to leaving (fixed one that was running) - I couldn't have been happier. I would recommend this company to anyone - they are honest, hard working, and extremely knowledgeable."
