We have been having severe problems with the drain system of one of our 3 new Lennox heat pumps, a…read more4 Ton unit. The unit continued to produce so much condensation that it backed up the drain system. I had been pouring the required amount of 'enzymatic cleaning solution'monthly, but even this failed to work. When I called the major A/C company that sold me these pricey units, they told me that it was a 'plumbing issue', and that I had to call a plumber. I did this a year ago and used the Sugar Land plumber recommended by the A/C company to do this. The tech from this company had a mini-snake and worked for over 3 hours, which cost me nearly $400! So, when the identical problem arose and the A/C company told me to call a plumber, I called the local company, Astro-Tech.
This turned out to be unusually fortuitous, as the business owner, Israel, was the tech who had been working on the old A/C units for the past 15 years, before we moved into the home! He knew that the problem was not with the plumbing in the attic A/C site, but down below in the sink of the master bedroom, where the above A/C drain line couples into the P-trap under the sink. Israel quickly disassembled the components of this ensemble, thoroughly cleaned it all out, then flushed out the line from above, and reassembled it. This is a simple procedure that anyone can do, so I now feel so empowered that I now know how to do this on my own. As a bonus, he performed the same operation on the other 2 sinks. But the cherry on top was when he told me that there is a product that can be mounted in the coil area, which is like a pill, that adds tiny amounts of a compound that will keep the entire system free of the micro-organisms (algae, fungi, and bacteria) that are the root cause of this problem. And once installed, it can last for an entire year! I found Israel to be very friendly, knowledgeable, punctual, communicates clearly and willing to share his information to help us keep our A/C systems up and running well. We will be using him to do all future maintenance on our systems. He is a very pleasant individual and his prices are very reasonable. I would give him my highest recommendation!
