We found Air Wave Technologies on Yelp and were impressed with the reviews we read, which were confirmed by the reviews on Google. They did a great job for us two weeks ago, installing a completely new split system air conditioning system, two new furnaces, with portable Honeywell remote control thermostats, and all new ducts in a 3-story house in the Hollywood Hills. Every one of their employees was very professional and very friendly. Their prices are more than fair. We couldn’t be happier with the advice they provided (which saved us a lot of money from the more expensive system we originally had in mind), the equipment they installed, the quality of their work, their prices, clean-up and follow-up inspection. We’re delighted. They have earned all the five stars reviews that you can see have preceded this one. Ask for Gabriel Cioffi–he’s a good guy and very easy to work with.
