"We had our tankless water heater drained - annual maintenance. They show up when they say they will and do it right the first time. In the past we've had issues with AC's, plumbing and more. Evey time they've exceeded our expectations and would highly recommend them for any heating, AC or plumbing. We've used them for well over 20 years and wouldn't want anyone else. They are the best."

"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"This place is a scam- DO NOT TRUST THEM! Just pay the extra and work with a BBB accredited company. We are extremely dissatisfied with the service we received today. We hired someone to save us time during a large demo project, but wish we just did it ourselves from the beginning to save time and headache. Based on the company's assessment, we were informed that our dryer vent had a significant blockage, so severe that it would require tearing out walls or possibly going through our new roof. We were obviously concerned about the potential cost and disruption. But don't worry, they're a construction company too... a little too convenient However, after the technician left, my husband decided to inspect it himself since we just had it cleaned within a year ago. Within an hr, he was able to clean out a considerable amount of lint, but there was no actual blockage obstructing the vent. In fact, as you can see in the attached photograph, a standard dryer vent cleaning tool could pass straight through the hose from the front to the back. Not to mention, there is plenty of air coming through the vent and none coming back into the home."
