"Pelle Heating & Air, Inc. came over did a really good job at first we had put in a larger air duck and its wasn't quite providing the results I was looking for and I let the owner Steve know and he came back over and made everything work good by putting an inline fan in and we even installed a new attic fan. I would recommend Pelle Heating & Air, Inc. as they really want to do things right and make sure that the customer is satisfied. I just say I'm very happy with the work and really recommend that you give them a try."

"PROJECT was really "A/C SOFT START INSTALLATION". I spent weeks trying to find an A/C professional who even KNEW about A/C SOFT START devices and could install them for me. I wanted the SOFT START device added so my A/C startup current could be reduced and place less of a load on my solar system batteries during a grid outage. The soft start device reduced the necessary startup power by 66%. Ahmed was the only person who even knew about them and did a GREAT job installing them."
