"This company is very good. My water heater was beginning to leak and I knew it was time for a replacement and upgrade. Ecoplumbers was able to schedule the day after my initial contact. Ryan offered a quote, explained what he planned to do and installed a new heater within 3 hours. Communication between scheduling services, the service technician (Ryan) and myself was excellent. I am very happy that I used this company"

"We received estimates from multiple HVAC companies, all the estimates were within a few hundred dollars of each other, and all the companies installed reputable brands of systems. One of the primary decisions to pick this company over the others was due to more favorable financing terms. There was a small snafu with clearance of the water heater exhaust, which was noticed by the technicians before beginning the work. Ultimately, they decided to fix the exhaust issue, which included a lot of extra work, but enabled them to complete the installation of the new furnace within a week that the work was originally scheduled. And they did not charge extra to do this extra work, which is a bonus. The installers, Kyle and Hunter, did a great job, were very knowledgeable, and were very personable/professional. We would highly recommend to others."
Logan A/C & Heat Services offered value, competitive pricing, top of the line Trane equipment, nice financing options that other companies did not offer. Dan was my sales rep that offered the above services. Bobby was the installer & was professional & did a great job. Install was scheduled on a Monday after I committed on a Friday; so very quick! Trane 20XV & Trane XC95m.

"After a recent problem with our gas line, our utility company mentioned that we needed to install sediment traps on our older hot water heater and our furnace. We called Flow-Rite for this, and they did the job quickly and well, as well as answering any questions that we had. We'll definitely be using them for larger jobs in the future.

"I purchased the "2-hour labor" offer from them before. They did such a great job that I purchased another one for this job. Before I purchased it I contacted them via e-mail to make sure this was something that they could do. I was told that it was and that 2 hours was about the right amount of time for the job. Nick showed up right on time and got started right away. I had an existing water softener that I wanted to install. I live in an older house (built in 1911) so there was no water softener hook-up available as they now build into newer homes. I had an idea on how to install it and shared it with Nick. He used his experience and improved my idea which also cut down on time and materials. True to their word, he was done in a little under two hours. The set-up looks very clean and professional. I did not have a chance to start up the softener before he left; he offered to come back if I had any issues. There were two options for routing the drain line so we decided to take the easier option. However, he said that if this option did not work out once I ran the softener for a while he would come back and re-route the line using the other option. I paid $160 for the 2 hours of labor and I will have some additional costs for the materials he used to connect the softener. I was thoroughly impressed with his work and I would not hesitate to hire him again. Thanks!"
