“Just a fantastic experience all the way around. Keith from Wagner Plumbing came out, and solved an old problem we had with a garage spigot. We had another plumber tell us in the past, there was nothing they could do with it. Keith was thorough, created a good solution, and we ended up with a perfect outcome. He was also worked and left the area clean, and took us through the steps of what he was doing, and was one of the best plumbers we have ever worked with. We know where we are going for Plumbing in the future!“

“As always Mark came through for me!! Not only was it the hottest time of the season, but I also had overnight guests…and it was a Sunday! Mark called me back within half an hour and was at my home early the next morning. He worked his magic and I now have a brand new air conditioner. I have been a long time customer of Mark’s. Now even my neighbors call Shark Heating and Air, because Mark is so thorough, competent, professional and timely. Thank you, Mark!!!“

“Technician arrived promptly, evaluated the job and then performed it very efficiently. Was also very polite and pleasant. Only took one star off because price was pretty high.“

“Needed a new furnace and A/C for a very,very old house. Complicated job, had several companies out to bid. Russ with McNally's provided the most complete answers, presented several options to solve my issues and was by far the most experienced and knowledgeable. Next came the installation team, on time and ready to do the job. Jeff and his crew were great, walked me through everything they were doing, worked efficiently and cleaned up. Mark from Jeff's crew even took one for the team and crawled through a dirt crawl space to wire the heat pump. Jeff showed me everything they had done (sheet metal work and venting pipes were super well done) and Jeff taught my wife and I how to use the new control pad, serious upgrade from my former Nest) McNally's also handled submitting all the rebate forms for me, so everything was very easy. Knowledgeable team, competitive pricing, great set up. At the very least, include McNally's in your list of options, they will easily be your best choice.“
