Short Version I…read morecalled LaCounte and iAirServices to fix a new install job by another company that went horribly wrong. They were professional, thorough, detail oriented and fixed everything that was not right with the previous install. They were able to make the temperature 5 to 6 degrees cooler, make everything nice and up to code, and significantly reduce the static pressure. If you are thinking of getting a new AC call these guys. They pay 100% attention to detail and will make sure it is done right to the specs of manufactures installation guide. There is a major difference between having a single AC technician installing your unit vs and installation crew where people are specialized. You will not have to worry about your install being done correctly. They might be a tad bit more expensive, but I assure you that investment will go a long way in having your unit installed correctly and having ZERO corners cut. We scheduled and they came out did the following (and probably more) : 1) Increase the return plenum for proper rebound zone. 2) Increase the supply plenum from 4' with a terrible workman ship to 8' with something picture worthy. Note: having a larger supply plenum is important part of duct design and helps with air flow. 3) Increase a return duct size to get appropriate return air, 4) Straighten existing duct work to remove restrictions. 5) Install furnace and evaporator coil per instructions. This is where they fixed specifically what the instructions said not to do which was done incorrectly by original installer. 6) Fix the electrical wiring outside to meet code. 7) Fixed the low voltage wiring to the outside unit that had the protective insulation worn off. This probably saved me an electrical short and thousands of dollars of damage a year or so down the road. 8) Sealed/glue the condensate pvc drain line. Seriously, the original installer did not even do this? 9) Moved the air scrubber to the supply side of the unit so I will work more effectively. 10) Remove all refrigerant, vacuum, pressure test and retest the unit to make sure there was nothing bad in the line. 11) Fixed furnace exhaust pipe to go to the right direction. 12) Fixed furnace exhaust to go to correct size outlet. At the end of the day the static pressure decreased from 1.4 to .9  and a 5-6 degree temperature drop but LaCounte wants the static pressure number better/lower. So they are going to come back and increase some of the supply ducts in our bedroom and living room because they are undersized and are not getting appropriate air to them. The crew itself fast, efficient, courteous, meticulous, and cared about the craftsmanship.  Heck, they even vacuumed up in the attic. Yup - that is right. They cleaned up after themselves very well and even cleaned up their mess in the attic. These guys are installation artists. LaCounte, his crew, and iAirServices care about quality and will not cut corners.  If you need a new AC, call them.  You will know that everything will be done right and if something isn't 100% right they will fix it. And they will be transparent... LaCounte said he is not happy with the static pressure number and they will come back to fix it by increasing duct size. If you purchase a new AC system, say a 16 SEER, and the install job is so terrible like mine was, it does not operate at 16 Seer. TBH, I would be lucky if the original installation were as effective as a 11 or 12 seer unit. I am curious to see how this system will handle a 15 degree day, but I suspect it will do quite well. I am lucky to have found these guys to help get us out of a mess. Learn from my mistake and call them first. I'm having trouble posting the long review as the character limit was too long....I need to figure out a way around this.

I'm a broker who has used Kosel AC & Heating since they started their business in 2001 after a…read morereferral to Steve Kosel, the owner, from a good friend. Since then I've referred Steve to more clients than I can count. I've used him to install multiple new systems for me, my father, my extended family in Austin and many, many clients. But new systems can be easy compared to diagnosing a lot of the little stuff. A lot of contractors, HVAC or otherwise, will blow a Realtor off over time because we tend to call with too many little issues and not enough system installs. Kosel AC shows up for the small jobs so we are loyal on the big ones. They shoot straight, cost less than average so consistently I don't need a second bid, and I don't have to worry about workmanship. Good customer service is just a bonus! Nobody's perfect and over 20 years with as much business as we have done there are going to be a few problems. On the rare occasion when we have had an issue, Steve has ALWAYS made it right. He has shown up more than a few times when we needed someone right now, and done some jobs I know he didn't really want at 7PM on a weeknight. I've not had a single unhappy customer when all was said and done. I thought to write them a long overdue recommendation today because I just sent him a referral to a client who is one of my most valuable. The kind I would only send to someone I trust with my livelihood.
