Brown's Heating & Cooling Hvac

“(Experienced, Professional, Efficient) - I’m happy to recommend them to family, friends, or anyone in the area. From the first call through installation, LLoyd gave me an honest diagnostic and multiple options. He quoted three paths. I had two other companies bid. I was not in a rush and did the homework. The others couldn’t compete and some left me shaking my head at their upsell tactics. Lloyd is upfront, tells it like it is. On the install day, Mike and Lloyd showed up early, did the walkthrough and absolutely rocked the install. TL;DR; For any future A/C needs, they are my first call. Trustworthy, skilled, local - call Brown Heating & Air Conditioning.“

RiteAir Heating & Cooling Hvac

“I can’t say enough good things about RITEAIR! Our air conditioning unit started going out this summer, and Jade and his team came to the rescue. They showed up promptly and worked tirelessly through both intense heat and then unexpected rain to get our new unit installed as quickly as possible. Despite the tough conditions, they remained professional, efficient, and incredibly courteous the entire time. It’s rare to find that kind of dedication and work ethic these days. We’re so grateful for their help and highly recommend RITEAIR to anyone needing HVAC service you can count on. Thank you, Jade and team!“

Pro Desk at The Home Depot Hvac

“Coming from a Lowe's fan, I was highly impressed and satisfied with my experience working with William aka Curly! He has shown great customer service and was very knowledgeable when it pertained to the tools I needed assistance with. I actually came in for a second time today (03/31/22) looking for some materials for a new wall project. I wasn't expecting to run into William, but I was really happy to due to the lack of knowledge some of the other employees showcased. I came in for one specific item and left with a high recommendation for a completely different and better material option. Thanks Curly for your customer service. Looking forward to working with you again!!!“
