"Awesome service and great punctuality. Wasn't a big window of time where I had to sit and wait. Company said they would be there and they were there on time. Had a faucet under my sink leaking and also had a garbage disposal installed while there. I will definitely be calling muddy waters and only muddy waters in the future."

"The 3 men the company had sent showed up ready to work.  They asked the best way to get to both units right off the back and appoligized for being a little late.  That didn't matter to me cause at least they showed up.  Within a 1hr and 30mins they had the old unit out and were getting ready to put the new units in.  Another 1hr and 30mins later they had the new unit (indoor and out) connected and had my cross over duct fixed and running.   They even check the gas heat to make sure all parts of the unit were working.  They did a great job of cleaning up after themselves and where very knowledgeable on their trade.  They were a great group of installers and I would like to thank this company for everything they did and gladly recommend them to others.

"9 hours- twice as long as expected. The old tank was impacted with over a foot of silt so they had to siphon the water out the top (not their fault). That alone put them behind by 2 hours. Then they had trouble getting the new up-to-code flu installed (their fault). But the team stuck with it and got everything in properly, instead of cutting corners or leaving it half-done and returning the next day."

"Excellent! Solar Energy keeps you informed every step of their process until the job has been completed. Friendly staff and very knowledgeable. Sales rep was always available to answer any questions or concerns. Once job was completed, they made sure that everything worked before signing off on the project! Great price package for installing solar panels/tankless water heater/water softener. Pleasure doing business with Solar Energy!"

"Marcie came out to give us estimate and install the fans if we agreed to the estimate. The estimate was well within my budget, but Marcie didn't have a 10' ladder on her truck, which she would need since the fans were on cathedral ceilings. We agreed to installation the following week. Marcie arrived as we expected, and in a very professional manner installed the two ceiling fans within the time frame we expected."
