Customer Testimonials Confirm McNally’s Heating and Cooling’s Commitment to Prompt on Time Arrival and Great Customer Service
“McNally’s Heating and Cooling were great! I called them on a Sunday morning when my heat went out and Brian McNally called me right back. He walked me through a few things to check while on the phone. When none of those worked, he said either him or his brother would be out before noon. His brother got there about 11:45. He quickly went to work and was done in 15 minutes. I would highly recommend them to anyone.” -

"Ugh Furnace stopped working last night. Called McNally's. They showed up within half an hour. I was worried about price..especially after the holidays. Furnace was repaired and running in no time at an extremely reasonable price. So nice to finally meet a Heating & Air Conditioning Service that's honest, knowledgeable and very reasonably priced. Thank you, Brian and Team. LOVE, LOVE, LOVE McNally's:) 5 star recommendation!! -
This was my first time using McNally's Heating and cooling. Brian arrived on time, was super friendly, informative and clear. He went above and beyond to find the right fix to the problem and I felt his pricing was very fair. I would highly recommend them, and will use them in the future. -
McNallys Heating and Cooling is extremely reliable and professional. Been using them since they opened and will be using them for any future complications. Very competitive prices is also a plus. Best around. -
McNally's installed a new furnace and central air conditioner in my home in the summer of 2013.
We have had no problems, and the techs were friendly, efficient, and explained what they were doing. I would highly recommend them! -
