One of my tenants called me on a cold Friday evening a few weeks ago, reporting that the furnace was making a screeching sound. He turned it off and alerted me to the problem. I called Aquality immediately. Steve assessed and fixed the problem within 90min of my call, making sure my tenant had heat for the cold snap ahead.
I have used Aquality multiple times for all of my rental property and personal residence plumbing and heating needs. Their staff are professional, courteous and do a great job every single time.
