When I called, I spoke to the owner, Lisandro, who sounded not only knowledgeable, but also seemed like he loves his job and running his company. I setup a day for him to come look at my old system and get an estimate. He arrived on time and he talked about what he recommended needed to be done, answered my questions and was accommodating of my requests. He recommended a Two stage Bryant 16 SEER 4 ton unit with a variable speed air handler (Models 226ANA048000, and FV4CNF005L00) and a super fancy touchscreen WiFi Thermostat. He also recommended that the air unit gets as much air flowing as possible since it helps tremendously with efficiency, so he said he'll change the current "closet" door where the air handler lives in, to a Louvre style door which has slats/grills to let air go through. He also was going to add a return grill which goes into to the adjacent room's wall, which at first I wasn't sure of, but it wouldn't be visible since the room's door would be blocking it from view. Anyways, he emails the estimate and also several brochures of the system he will be installing, plus all the tax forms and rebates that I was eligible for. I agreed to the contract and I scheduled with him a date to start. On the first day of installation, Lisandro and one of his employees showed up to do the work for the outside and another one came later to do the inside work. They were able to remove the old inside and outside units and also setup the new outside unit on a new cement slab after digging and replacing the old lines and pipes. The inside unit's "closet" was mostly preped and the new return was cut out, but it all still needed to be finished the next day and the air handler installed. The new closet door was also installed today. Luckily it wasn't unbearably hot that night, so not having AC wasn't as bad. On the second day, they finished all the closet prep and installed the air handler and everything got connected and working. They did apparently get the wrong thermostat though (it was very similar), so a new one would be installed the next day. Also unfortunately, they found that the current electric wire that feeds the outside unit was rated for 40amps but the new unit needs 50amps, so now I needed to have an electrician run new wiring because it could be a hazard. I wasn't too happy about this, but I understand issues can come up. Lisandro told me we wouldn't be able pass inspection until the wiring gets done, so I scheduled an electrician to come by ASAP which was a couple of days later. On the meantime, I was already enjoying a new AC! On the third day, the new thermostat was installed, but during the next two days I noticed the humidity was showing as very high and the air didn't feel as comfortable. I spoke to Lisandro and he sent out his employee to take a look again. The issue was fixed and now the AC was REALLY NICE AND COLD! So now I just waited for the electrician to come by on the scheduled date (2 days later). Lisandro's sent his employee Luis to also meet with us to help answer and explain to the electrician what was needed. The work was done in a couple of hours and now all that was needed was to finally schedule our final inspection with the city which was set for a couple of days later and it passed easily since everyone did a great job. I felt like North Pole bent over backwards to make sure everything turned out well. There was communication throughout all the stages of the installation. Even though there were two issues that came up, I still feel like these guys deserve five stars for the quality of the work, the customer service and communication they provide. Once everything was done, Lisandro provided 2 year supply of filters and a company shirt for my wife and I. In conclusion, if you want a reliable, hard working, non scammy company, that will treat you right, then hire these guys!
