"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"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."

"I would highly recommend Ray’s Rescue Plumbing. He was very clean, prompt, courteous and knowledgeable. We had several issues ranging from leaks, repairs and installing a tankless water heater. Ray’s prices were competitive and he actually saved us a few thousand dollars from a previous bid from a ‘not so honest’ plumber."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

"Very prompt in responding to my initial inquiry (Sunday no less) and salesman was terrific. Installation took 2 full days by a team that seemed professional and knowledgeable. I was shocked however by the fact that 2 men on the installation team smoked all day long. My property is rural with no fire hydrants - the prospect of fire is terrifying to me. At the end of the 2 days the system was installed but it took an additional technician coming out after the crew had left to get the system functional."
