If you’re looking for a HVAC company, I highly recommend Guardian heating and air. They guys were extremely nice, tidy, and most importantly they do amazing work.

It's not often that you actually meet with the owner for an estimate, especially in the HVAC world. Alex thoroughly detailed everything needed to replace an old unit, and bring everything up to current code. The crew showed up early and finished the job efficiently. Thank you Guardian Air for making my project EZ

Review I scheduled Guardian Heating and Air Conditioning, Technician. The technician Matt Buter was excellent! He called ahead to let me know he was on his way, which I appreciated. When he got here he enter dusted himself and went right to work. He also gave me a detailed description of what we needed to repair my A/C unit. I would highly recommend Guardian H/A. They are the best of the best. John Parkin

Alix Mckenzie

Guardian Heating and Air stands out in an industry that is increasingly dominated by private equity owned companies focused on pushing average ticket sales. The owner and his team take a very different approach. They prioritize education, transparency, and what is truly in the customer’s best interest. From start to finish, the team was professional, efficient, and clearly well organized. Their systems made the entire process seamless and easy to navigate. What impressed me most was their transparency in billing. The invoice clearly broke down each service performed, so there was no guessing about what work was done or why it was necessary. It is refreshing to work with a local HVAC company that values trust and long term relationships over quick sales. Guardian Heating and Air is a great local business to support, and I would confidently recommend them to anyone looking for honest, high quality HVAC service.
