"They replaced and reconfigured the aging and inappropriate plumbing system in our home. They also cleaned our furnace and discovered things that had not been addressed in past "professional" services. We are very happy with their work and recommend them highly."

"The company's responsiveness to our urgent situation was extraordinary. The owner made a 60 mile trip to examine our situation on Sunday morning! He expected at least a week before they could do the work, but he got it done the next morning so that we would have safe water...we had been waiting for another contractor for more than 3 months! The installed radon mitigation system has performed flawlessly. We are grateful and confidently give AquaMax our highest recommendation."

"Technician came to the house and analyzed the problem. It was determined that the cost of repair was over the allowable Choice Home Warranty limit and it should be replaced. Choice Home Warranty issued their replacement cost. This cost was unacceptable and I challenged their figure. After some negotiation I was offered an increased settlement amount. I still balked at their offer but I was told to take it or repair my old microwave. I finally accepted their amount, even though it is still well below what it will cost me to replace the unit. I might add that the existing microwave has the convection feature and I want to replace with same features. The cost that I will receive also does not include any removal, disposal or installation costs. At this time I am debating whether I will continue with Choice Home Warranty or consider other options."
