    More than one time I've needed emergency service and they usually had someone there within hours.

    The BBB has both my complaint and review. Read them and all other non biased truthful issues. Don't…read morebecome another BBB complaint. The company is not accredited for a reason. Everything Mack installed had to get replaced and redone in 2019. He sold me a 100,000 BTU 96 AFUE unit and after being paid. I was told it was a 80,000 86AFUE unit. To post a lie earns a lawsuit, watch how these facts remain on this site. I did contact the PA Attorney Generals Office and was offered $2,000.00 from the company to make my complaint go away. As I had to replace and redo all at over $5000.00 and had already paid Mack 4700.00 I refused. Who offers 2000.00 when they are correct? No one. Remember the BBB site, it's your money Again you cannot post a lie, it's called liable watch how this post remains here forever

    Amazing customer service, attentiveness, and overall nice guy. I found Mack through Yelp (thank…read moreyou). When I found that he was local and saw his ratings, I knew I had to try his service at least once. I switched from a bigger company who installed my equipment because it was difficult to get service and I had to speak to 2 or 3 different people to arrange that. I was tired of having to make phone calls, wait for replies and being made to feel that people were doing me a favor by charging me to come out for work. Mack called me back himself within 10 minutes of my message. He "interviewed" me on the phone about the problems I was having. He went to my home, serviced my unit and had it running right away. He also gave me advice and suggestions about keeping it running well. The price was a little cheaper than my previous company, but still within the range for an annual service. I will continue to use Mack because he seemed to care about my home as if it were his. Paying him was the last thing on his mind, he wanted me to be happy first. That's difficult to find; it's a pride of craftsmanship that is lacking in the bigger companies. I will use Mack from now on and you should too.
