"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"I don't know enough to compare (dollarwise) the tankless water heater I purchased to others in the market. I can say it's an impressive piece of equipment and is providing my desired level of service. I now have hot water throughout my home in seconds! AND, Dave impressed me immediately as a sound, honest, energetic business man and technician. In no time he and Carl were at my house doing the work I desperately needed. It was dark when they finished but they lived up to their word in fixing my hot water problem "today"!"

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"The day the service was scheduled did not go well. We were scheduled between 8 and 12, but they called in the morning to move it back to 10 to 2. I called them after 2 because we had not heard anything. The technician finally came around 3:45. I think it is very poor customer service to expect someone to wait all day for a service call. Once the technician arrived the service was done very professionally. He did find that they should have enlarged our vent with the install two years ago, and they will have to come back and do that. It makes me think they did not have proper attention to detail during the install. There also was an up-sale so that a $79 service call ended up costing us over $450."

"Furnace blower would't run. James explained the problem & installed the condenser-which he had on the truck. He also explained some "issues" that might come up in the near future. He performed some maintenance that was overdue. Seemed very thorough & most importantly, the heater worked properly when he was done!"

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."
