• Extremely pleased with how Guardian handled this project. They worked with us on the bid, kept us informed at all times on timetables and appointments. A top-notch professional organization. We highly recommend Guardian and their crew. We would not hesitate to use them again in the future.

  Daniel P.★★★★★

• Her service tech was very knowledgeable and great to work with.

  Ken B.★★★★★

• Prices were in line with other quotes I received. They reviewed and explained each line item on the quote so I fully understood what was being done. The install team showed up on time and actually finished earlier than I expected. They were extremely professional and courteous. I would 100% recommend Guardian.

  Kevin S.★★★★★

• Job was completed and thoroughly check and inspected.

  Aaron V.★★★★★

• John did a thorough follow-up check.

  Andreas★★★★★

• Quick response, accurate diagnosis, courteous and respectful technicians (2). My only complaint is that it took two weeks for the part to arrive and to be installed. (Notice this had to be claim to the manufacturer insurance) so it probably not on the company (guardian) fault. I am super pleased with both technicians, both did a great job, organized and clean afterwards.

  Janice D.★★★★★

• Leo arrived promptly and installed new 4" duct work for all 3 of my bathroom exhaust fans. Next Leo made 4" exhaust ports with one way valves on soffit to ensure the hot and humid air flowed outside of my house. Great work in a very hot attic! Highly recommend Guardian Heating and Air.

  Jim M.★★★★★

  Candice R.★★★★★

• Cam was very pleasant to have service our A/C unit today. He is courteous and professional. Thank you sending such a nice person to our home.

  Lisette L.★★★★★

• Fantastic and professional

  Dan C.★★★★★

• First, I very much appreciate how quickly Guardian sent a technician out. Leo really took his time to diagnose the issue we are having and explained it in a way that made complete sense. He was honest, friendly, and genuine. I appreciate that Guardian is committed to getting to the root cause of our issue rather than quick fixes as other previous companies have provided. Highly recommend Guardian and am so glad we found them!

  Jenna K.★★★★★

• Fantastic! Only AC company I called who actually diagnosed and solved the causes of high humidity inside our home.

  Scott E.★★★★★

• Thank you very much to Guardian for getting me up and going in a time of need. Late one night the compressor died in my upstairs unit and had me trying to sleep in 86 degrees. Guardian was able to quickly get someone out the following day to diagnose the issue, provided a temporary unit upstairs so I could get some sleep that night, and sent out Ernie Rose the next day to install a new unit. My house was built in 1908 and always has some unexpected obstacles, I am thankful to Guardian for working through them with ease. I highly recommend them.

  Scitendo 0.★★★★★

• Leo was top notch! He was earlier than expected and very informative about the work.

  JamesB★★★★★

• I call around 9 am and by 2:30 our air conditioning was working. Thank you so much for such a speedy response.

  Annie D.★★★★★

• After racking my untrusting brain on who to call so I don’t get overcharged or screwed around somehow, I finally called Guardian and I was so pleased! Not only the response time, but the patience and informative nature of John was exactly the person I needed to show up. He thoroughly explained the situation and did the repair promptly. I was able to go about my business in my home as he did the repair. John was a kind and pleasant man. The repair didn’t take long and he explained why the situation happened in the first place! Guardian will now be “our” HVAC company. I say call them, you won’t be disappointed.

  Cristina J.★★★★★

• Leo showed up right on time, about 40 minutes to do service call. Seemed real knowledgeable and explained everything he inspected on the unit. Very respectable, would request him for next service call.

  Jeffrey W.★★★★★

• Amazing service, always thorough and professional.

  Amy G.★★★★★

• Armando Cass did a great job , Very nice person

  Anabela U.★★★★★

• Anton really knows what he's doing, is very professional and explained everything. It felt more like a visit than a service call to inspect my init and give an estimate for repairs.
