ATS Mechanical installed a solar powered attic fan in my home to help with the build up of heat in my attic. The fan was installed in a few hours and has worked better than expected. It is exteremely quiet, cannot hear it inside the house at all. It has also saved me money by having my AC run more efficient in the hot Houston summers. The value in the long run was well worth the cost.

ATS Mechanical is the only HVAC company I will use. They give you the best bang for your buck on all systems. I have used them twice--once to install a Mitsu MiniSplit and once for a complete overhaul of a 2 ton unit. Both systems they installed were premiere systems with 10 year warranties. I am most pleased with Eric who is one of their on-call techs, Barry who runs the company, and Lillie who always puts a smile on my face when I call the office. I've recommended ATS to several friends who are all extremely pleased with ATS.

I had ATS Mechanical North Houston come out this past week and zone the heating and A/C ductwork in my attic for two guest bedrooms and bathroom. It has always been a little warm down there; a thermometer showed it was running about 3-4 degrees warmer than the rest of the house in the summer months. ATS was here for 11 hours (8:30 AM until 7:30 PM) working non-stop. They installed new 7 inch ductwork and dampers plus another brand new wireless thermostat that controls just the two guest bedrooms and bathroom area. Amazing! I never really thought it would work as well as they said it did, but it is working better than I could imagine. I also have noticed that the rest of my house is running cooler and exactly ("true") to my original thermostat's temperature that is locate near the master bedroom. (My house always felt like it was a little bit warm in the summer, even though my HVAC system is only two years old.) Eric D., the installation crew manager, had me go with him up to the attic to see the work that they completed and I was blown away by all of the new ductwork that I saw. Most of the original ductwork is gone but you can definitely distinguish the old ductwork from the new ductwork - the old ductwork isn't nearly as well insulated and it is only 6 inches in diameter vs. the newer ductwork that is 7 inches. It isn't cheap - $4600 - but the cost to install a mini-split was much more. I have a one story house that is 2,427 square feet; house was built in 2002. (ATS Mechanical was the second HVAC company I received a quote from; I had another company come out but they wanted to install the mini-split system.) Now I wish I would have done this sooner. https://ats-mechanical.com/ ATS has three offices but one phone number that you call: 346-572-8856. They also give military discounts as well.

I was told I needed to replaced the mother board in my ac unit and that the unit was not under warranty. He called Lennox in front of me. The unit is 9 years old. I was quoted $7,060 to replace the mother board. He wanted me to replace the unit at a cost of 15 to $20,000. Another contractor told me that the unit is still under warranty (I called Lennox, and they verified it.) He quoted me 1,700, which is still too much. I have been told that I should only pay about 200 to $300 since the part should be free. I'm not happy, and I'm getting more estimates.

I was quoted $7,060 to replace the mother board on my Lenox AC unit. He wanted me to replace the unit at a cost of 15 to $20,000. The quote was 3 to 4 higher than anybody else. There were some issues regarding the warranty on the unit. The owner, Barry, communicated with me and cleared up the misunderstanding. I did not use them because of the high price. I can't attest as to their work. I paid $99 to join their club, and they did not charge me for the estimate/quote.
