I highly recommend Luke and Air Dynamics.
Our 20 year old HVAC units were starting to become a bit risky - who wants them to die in the middle of an Austin summer? We got quotes from three different providers, Luke and two "service companies". The service companies tried scare tactics with a woman and totally missed/neglected to mention that we had lost all the insulation around my ducts (what was going to happen when they actually were doing the work? "oh ma'am, it turns out that....and for an extra $$$ we can fix it...."????)
Luke came in, did a thorough review, described everything that he found, and gave me honest recommendations. His bid, with everything, was on par with the service company (the ones that didn't mention the ducts). He specs units that were the right size (not to big, not too small) so that we didn't overpay for something that we didn't need.
His team, when they came to install, were clean, curteous, efficient and friendly. During the replacement a small fizzure (can't call it a c r a c k because that is an inappropriate word with CitySearch) appeared in our ceiling. Luke came right out the next day and fixed it, with no fuss.
We have now had our first electricity bill with our new units and have already seen a $50-75 reduction in our bill.
I first called Luke based on the CitySearch recommendations and I was not disappointed. I HIGHLY recommend Luke - he does air conditioning/HVAC and he does it well.
