Andrew Decke

Professional and efficient! I highly recommend!



Ryan Wilde

Honest, professional, highly recommend!



Nicole Williams

Great service and tremendously helpful! Ryan always takes great care of our unit and has helped us quickly with any emergency repairs. He did a fantastic job on the install of our new unit. He is our go to for all our a/c and hvac needs!



Justin Otte

Ryan and his crew were polite, on time always, and explained the in’s/out’s of my new system in terms that I could understand. I recommend his company to all my friends and family in need of an AC, hot water heater unit/maintenance. 5 🌟’s is an understatement thanks Ryan and the crew!!! …



Alyssa Otte

Ryan is an extremely hard worker, knowledgeable and his work definitely reflects that. He’s always gone out of his way to come fix any issue I’ve had pop up at the last minute.
On top of all that, he doesn’t gouge you with steep prices like a lot of companies here do and is very reasonable.



Me, Queen!

Prompt, professional, and proficient! When my AC broke down during a heatwave, I was in urgent need of a fix. Ryan responded swiftly to my emergency call, quickly diagnosed the issue, and had it running smoothly in no time. Exceptional service that went beyond my expectations. Highly recommend!



Patrick k

Guardian came to the rescue with my home AC service. My fan motor was going bad and needed a capacitor replaced in the middle of the summer. After my call to guardian they were out to repair the next day. The technician Ryan was knowledge and service was quick and flexible to my schedule. Service was very affordable and fair. If you need a consistent AC check up and repair service I highly recommend guardian heating and cooling. They are currently my go to. They even gave me a free quote for a new installation when my older system inevitably goes kaput. Thanks Guardian!




Where do I start? And if you are choosing your next HVAC tech/company based on reviews, I would read this on to the end. Like some of you reading this, I am a do it yourself person. So it’s rare I hire out for work but in this case, it was well worth the money to have a knowledgeable, nice, friendly person come to our home and service our Air Conditioning Unit. Ryan is honest and fair and as far as pricing, which varies per situation, I would say we got more than what we paid for. I say that because he wasn’t trying to upsell us on parts or service. He saved me a great deal of time and as a business owner myself, time is money. Let’s just say, Guardian Air is my new HVAC guy. And there is no better feeling when it comes to serious residential mechanical systems than knowing you got a guy. And one that will do it right. Sure, you can shop around, you would be remiss if you didn’t call Guardian Air. 5 Star all the way.



Holly Cillitto

Guardian came to my rescue when my heater stopped working. Ryan came out the same day and had the heater running quickly. He even returned the following evening to install the needed part. Ryan is a very knowledgeable professional that truly cares about his customers’ needs. Guardian is now my go to for all my HVAC needs!



Alvaro Vasquez

Had a problem with my brand new unit, called Ryan and he was able to come the same day to diagnose it, removed the bad part and exchange it, he came back next day and had it running again, really professional, knowledgeable and good price, would highly recommend them, and I will use them again if any other problems.



Joe Perez

Ryan is a top-notch professional with the perfect combination of technical expertise and the customer service skills to match. He was extremely helpful and patient helping us decide what system to get, and was extremely flexible with our schedule and installation process. He explained in detail how to set up the system and walked me through the online features. Ryan then devoted generous amounts of time to walk me through the new thermostat system registration and controls on the Trane application. We could not be happier with the process, service, and fair pricing of a whole system. We got the best and service deal all around. 100% recommend Ryan’s superb services.




I’ve called on Ryan twice for urgent repairs to my AC and he was quick to respond and get the repairs completed! He has been a huge help and while no one wants to call in for an AC repair he made it as painless as he could. I’ll definitely reach out or recommend his services again to anyone that’s in need!
