In 2002, Airworks (Chris) installed an a/c unit in my first home. In 2005 I asked Airworks to return and install 3 A/C units on my new home, and my in-laws. When I buy my next home, I will be calling Airworks This should be enough proof of their expert and very professional service. However, I will also add that I chose and will continue to choose Airworks because of Chris' integrity. There has not been any haggling necessary, as his prices are very competitive but more importantly, he is extremely reliable. His serviceman know exactly what they are doing and will offer up as much information as you'd like without sounding salesman-like.
Besides the 3 a/c units, I've purchased an Aprilair Air Cleaner which worked so well that I had Chris install one for a friend. I am now considering a ERV which is essential for fresh air and good health.
thanks
