My AC unit outside stopped working. It was 100 degrees outside and 82 degrees in my house. My husband had heart surgery last year. My son has asthma. I called numerous HVAC Contractors prior whom all told me sorry it will be a week or 2 and parts have to be ordered even though I explained the urgency. And they claim to have emergency services. So I finally got down my list and called Dave who offered to come same day after I explained the problem and size unit I needed. He picked up all parts prior to coming. I am very blessed to have called. He worked very hard and stayed late to ensure i had air conditioning. Thank you again for your time and help.
