Protecting the
Direction of
Water Flow

Backflow can occur when pressure conditions change and water flows in the opposite direction from its intended path. Depending on the plumbing system and connected equipment, a backflow prevention device can help protect the potable water supply from cross-connection concerns.

Our team evaluates the visible backflow assembly, related plumbing connections, and the reason for service. Whether you need backflow preventer installation for a new project, a backflow inspection, or backflow prevention repair, we explain the condition of the device and the recommended next step.

Because requirements can vary based on property type, system configuration, and local rules, we focus on providing professional plumbing support and clear information about the condition of your equipment.

Came home to a 90-degree house with the AC blowing hot air—of course, it was after hours. Thankfully, James Lorenzo was the technician on call. He arrived quickly, was professional, kind, and thorough. He showed us the part that had burned out and had our system cooling again in no time. So grateful for the fast and reliable service!

 Trustindex verifies that the original source of the review is Google. Lance Hawk was great at servicing my hvac. He went above to make sure I was taken care of.

7/9/25 update: Scott Nelson helped me through a terrible situation as a patient of Dr Gruining. He was kind, professional and very patient with me. He came  last Saturday where we discovered my duct work was holding water despite my many services (and complaints of high  humidity prior) and had the duct work replaced correctly in a very timely manner, even redirecting the drain that yall previously redirected (into an arra that floods with rain so it made it difficult to drain during rains. The ducts had so much water it was pulling off the back of the unit (unit NOT installed by Cool air)  The cost to replace the ducts wasn't easy as a single parent who is paying a mortgage on a new place Ian took. Scott came back today thoroughly going thru checking the duct work, cleaning and checking outside unit, sanitation of duct work and even using a thermal camera to double check areas. He was kingmaker thorough and patient with me and explained everything to me. I just don't understand how long this went on with keeping up with my PMA services, but I'm very happy with Scott his work, kindness and compassion. I'm praying i can now continue to heal, although it says it will take many days to dry out home. I have one dehumidifier I'm using and moving around to try to assist dry out. Dr Gruining has been copied on all paperwork.

 Trustindex verifies that the original source of the review is Google. I had Coolair install a mini split garage AC and the installers (Julio and William) were outstanding.  They were both very personable and treated our house as if it were their own.  Their work was extremely neat and professional, all pipes/lines were straight and plumb, the unit looks and works great. I highly recommend Coolair.

Update…(7-8-25) I was very pleased with my last two cleanings, 1st by Aaron and 2nd by Dakota.  Both were very professional, explained everything clearly and answered all my questions and kept everything clean and neat.  I would highly recommend either technician for your HVAC needs.

 Trustindex verifies that the original source of the review is Google. My experience with Coolair, especially with Roland Finley, was exceptional. Roland was very kind and explained what was going on with my A/C unit and guided me along the way, as a family member would. Response time was great and I am so grateful that Roland was sent my way. Thank you, Coolair and, especially ROLAND!
