HMH Horizon Mechanical LLC.

Professional, Friendly, Courteous, and explained what they were doing and why.

The scale deposits that was supposed to dissapear  within  3 weeks in the shower. toilets, sinks, dishwashers, etc, never happened.  Had to replace many toilet flush valves and sink parts, continue using special dishwasher lemonshine to get rid of etching on dishes and glassware. We continued to make service calls to Clint Snow, Service Mgr., went ignored.  The last and final  call was 9:30 AM on a Friday September, 2012, he was supposed to come by,we contacted him, about 10:00.he was  in El Paso, TX said he would come by that afternoon which didn't happen. After that, we gave up. The system never did perform as promised.

Two workmen came to the house to replace the filter. They did not have proper tools. They did get it loose with difficullty. A special wrench is needed to remove and replace the filter. The workmen were unable to provide the wrench. I was able to get the wrench on line at a later date. I tried to change the filter later only to find out that even with the proper wrench I could not remove the filter cover to change the filter. Even with enough force to bend the brackets and pull the screws out of the wall I could not get the filter cover loose.
I intend to have another plumber remove the whole house filter from our plumbing system.

He is very thorough, reasonably priced, and professional.  He is very honest. 

Update 4/9/2012   
I called them to service my Master Cool system, but they had no record of working with me previously. It was like working with a completely different company. The cost estimate was also extremely high.

Horizon Mechanical demonstrated real professionalism. They came on time as scheduled (early in the promised window), and did the work quickly and efficiently. They also gave advice for the next steps in the preservation and restoration process, as we had suffered a great deal of water damage before we discovered that the pipes were broken. We were greatly relieved to have our water back!

They were on schedule and did a great job. They were efficient and got our heater working because we were tired of freezing to death so that was good. It was right after Christmas and on a holiday weekend so it took them a little bit of time to get here. The price was fair but I always think it could be better.

After being burned by another plumber in town, we called Horizon. They were awesome. They were fast, efficient, affordable and very pleasant to deal with. We will definitely use them again.
