"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"John has been our go-to guy for several years now. We live in an early 70s home, and as with all older homes there are repairs that are needed fairly often. From the first time he worked for us, identifying that a leak originated from a roof vent that had been knocked slightly askew in a storm and rain water had gradually seeped down the pipes and terminated above our kitchen cabinets, he has always been prompt, courteous, professional in every way, and just an all around nice guy to work with. And the pricing has always been fair. Since then he has installed a number of appliances and fixed sundry leaks for us. Can't recommend him or his company enough. Give them a try."

"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"Tim gave us an honest evaluation of our existing water heater and options for repair or replacement. We decided to replace the water heater and Tri-State scheduled the next day. Installation was professional and l think Tim is the kind of craftsman you want representing your organization. The fact that you install the Rheem brand helped close the deal."

"I purchased the $30 promotion for a hour of service. The owner showed up with an employee. They installed the water heater and unclogged the drain in 2 hours. I paid $170 plus the $30 promotion through Angie's List. I saved over $500 compared with the plumber that I had previously planned on using. I had a small connection problem on the water heater. I contacted the owner and he arrived at my house a couple hours later, 8:00 pm. I was completely satisfied and plan on using Froggy's in the future.

"We signed contract on 4/15/2013 and were told by salesman that jobs were approximately 4 to 6 weeks out.  The night we signed the contract, ask for a floor sample to be sent to me so I could pick out counter top and paint.  The salesman also said that this product would never mold or mildew, especially the joints, because their product was formulated for heavy moisture areas. (Later found out that is NOT true, from another customer.  Salesman also stated that we wouldn't probably hear anything for a couple of weeks, then we would get a phone call to set everything up.
By May 15, I had repeated tried to contact salesman, via phone and email as to why no one had contacted me to set up install and why flooring sample was not sent.  Salesman never returned any phone calls and then only via email did I receive any response.  Each time with an excuse as to why nothing was happening.  FINALLY received flooring sample (a index card size on June 3rd), followed by a phone call on June 5th, from someone at the Rebath office asking if they could come do the tear out on June 7th, with drywall repair on the 8th and install on the 10th and 11th.  I stated it was a little short notice and was told if I didn't take that date then it would possible be another 3 to 4 weeks out.  So wanting to get the bath done--since they had half of my money (3,600.00), I along with my husband agreed.
When I arrived home on the 7th, from work, which was around 2:30.  It was a fairly hot day---the front door to my home was standing open.  No one was going in or out and the tear out guy was in bathroom, with very little work done.  Because of the soffit work--we ask him to save the insulation so it could be placed back into attic, he did so.  Tear out man was in home till late in the evening--not something you want to happen due to most people have to work the next day.  He kept leaving front door open, all the while the air conditioner was running to keep up!  It was our understanding that all the old dry wall would be tore out, but that gentleman said that because it was not spelled out on contract that he couldn't do it and if we wanted him too, that would be a work change order, which would cost us more.  (ONCE AGAIN--was told something different from salesman, and this was not our first construction project!).  He also left a mess on the floor from the removal of the old tile--my husband had to get the shop vac out to get up the debrie!
The drywaller's arrived on the 8th--there was texture on the old drywall.  We asked installers if they were going to match the new drywall with the old by putting on texture, since all tear out was not done.  They said no, but could do it for a $100 more money.  We didn't agree to it because I refused to be nickeled and dimed!  They finished their work quickly, putting on the first coat of mud over taping and stated they would be back on Tuesday (Jun 11th) to sand and put second skim coat on joints.
Installer showed up on Monday, June 10th on time.  YEA!  He was friendly, respectfully of our house and very efficient!  However the tub that my husband and I ordered and thought we would receive--was the wrong size.  A new one was brought out at Rebath's expense.  (Later found out the salesman had wrote down the wrong size!)  The installer was there late into the night on Monday and cleaned up very well when his part was finished.
The drywaller's didn't arrive the next day.  I call Rebath by 4:00pm to find out what happened and they were surprised that they didn't show up and I was asked why I didn't call before 4:00 to see where they were!  How is that suppose to be on the customer.  After a couple of more phone calls between myself and the very nice lady that answers the phone at Rebath, it was arranged that they would come out later that week.
My husband also had to make repeated phone calls to have Rebath to come back out and finish the job.  Because they promise by them was to put your bathroom back and in better shape!.  By Friday of that week--Rebath sent a gentleman out to finish the job--put the door back onto the bathroom and cut it down to fit since the new floor made the toekick stick up too much and the door wouldn't shut.  They also needed to put the baseboards back onto the wall and connect the plumbing up at the sink. 
A two day turn around that is promised by Rebath in their advertisements, turned out to be a week long job--only to be finished and done right after much inspection and phone calls!!!!!!
After a total of 7,200.00 spent, I can only hope their product holds up like they promised!  Leary due to the fact that their promises haven't meant nothing yet!
