"I had such a great experience with Liv Air! They serviced my boiler, and from start to finish the process was seamless. Leo is incredibly professional, easy to speak with, and genuinely such a nice person. He?s honest, reliable, and you can tell he truly cares about his customers. The technician who came to replace the parts was also wonderful ? very clean, respectful, and efficient. I?ve dealt with other companies before, but no one even comes close to the level of service Liv Air provides. Their pricing is fair and reasonable, and they answer calls right away, which is so rare these days. I?m honestly taken back by how great they were. I highly recommend Liv Air!"

"My AC went down during the hottest part of the summer and I was desperate for a replacement. After several quotes, I was lead to Oscar, Owner of Whitestone HVAC, and I couldn't be more happy with the results. He replaced my central air and converted my baseboard heating to central heat with a BETTER product for significantly less than the competition. He also finished in record time working in temps of over 100 degrees in the attic. It has been more than a month and the system is operating to perfection, silently cooling and saving me money on my energy bill. If you're looking for a Certified, Mater Technician, who will work efficiently to give you the best results for the best price, Whitestonehvac.com is your solution."

"Excellent HVAC and Solar installation services! They did a great job installing a new HVAC system for us a few years ago, so we sought their services again for Solar installation. They were very professional both times: provided pricing right away, technicians were polite, and job was completed in a thorough yet efficient manner. Jobs well done!"

"Excellent professional service company. This was an emergency replacement of our 2nd floor unit during a heat wave that meant Whitestone had to work in our attic in extreme heat conditions! They did a fantastic job and made sure we were up and running as soon as possible."
