5 stars – Professional AC Replacement
I recently had my AC unit replaced by Guardian HVAC LLC, and I couldn’t be happier with the service. From the initial estimate to the final installation, everything was handled professionally and efficiently. The crew showed up on time, explained the process clearly, and completed the work faster than expected. They cleaned up thoroughly afterward and made sure I understood how to use the new system. The new AC is working great—quiet, efficient, and keeping the house comfortable. I highly recommend them to anyone needing HVAC work done right.

Guardian work were very experienced and professional and did a great job with my new Bosch HVAC installation and removal of my existing Carrier HVAC system which had issues and was out of warranty

Guardian HVAC was right on time and very efficient in completing their work. Armando is a true professional technician that knows AC systems very well. I would highly recommend this company if you are looking for a reliable and trustworthy AC service.

I used Guardian for the first time on July 11 for maintenance on my HVAC system. They were a referral from a relative. They were prompt, thorough, courteous and demonstrated their expertise. Armando was our technician and he was very professional, friendly and kept us up-to-date on his progress. He also gave us some tips on maintenance. I would highly recommend Guardian for HVAC service and repair.

I contacted Guardian to get a second opinion following an extremely high estimate from a large corporate HVAC business. The owner was pleasant to converse with, answered all my questions, and set up a visit to diagnose any issues and supply an estimate. The employee, Leo, arrived timely, was courteous, answered all my additional questions, and supplied a diagnosis quite different than the other HVAC company. I also found his estimate for repairs to be far more reasonable. This is just mostly an initial impression review, but the team at Guardian were very impressive and certainly have my recommendation.

Alex and his team are highly professional and they will never over charge you or upsell you. They explain the situation and let you make an educated choice!

I cannot say enough wonderful things about Guardian! Alex came out and got us an estimate the same day. Gave us options and helped us choose what was best! They went out of their way to make sure we were able to keep our dog/cat door AND increase efficiency! All of the gentleman that were here to install were extremely professional and super friendly! I highly recommend Guardian Heating & Air!

Alex and I go back several years... He replaced the a/c at my house and just finished doing my daughters house. My daughter said all of his employees are hard working and extremely polite.

I call Guardian late in the afternoon bc the compressor stopped and had no air. They came out within 2 hours. Leo was the technician and so very happy with his expertise and professionalism! I hope he will be the technician for the install of the new compressor!

Guardian Air goes above and beyond AC maintenance and repair work. They problem solve ventilation issues, high humidity and complex issues related to work done by other sub contractors. Getting to the root of the problem is essential. Their whole team is competent and caring. We have finally found a company we trust.

Absolutely awesome service. Our systems capacitor quit on the hottest day of the year. They got here and had it fixed in under an hour. Getting better duct work installed next week too to make the system more efficient. Armando was great to work with!

Not only is this company exceptional as a trusted vendor for my company, but even in my personal home. Our AC stopped working and our home hit 90 degrees inside. Called them, they showed up, and got our home freezing cold just as we like it! So now my pregnant wife who works from home and all our pets can be comfy again.

Time and time again I will recommend this company. Everyone that works from this company are true extensions of the owner. Demonstrating knowledge, integrity, and trust with their clients.

Here’s a few more stars because 5 is not enough.

I highly recommend Guardian heating and Air! Alex and his team are great to work with! Our compressor went out. We decided to just get a new unit put in because it was just a matter of time before everything else started to give us problems. So glad we did because this new unit is so quiet and it doesn’t sound like it’s struggling like our old unit! Ernie was awesome and so was the young man with him but I can’t remember what his name was. They were both great! Thank you so much Guardian heating and Air.

Alex and his team are sensational!
Leon was prompt-he tuned up and flushed the system. Reasonably priced and competent. Been a real estate investor in PVB area for over a decade and this is one of the best HVAC teams in the area
Thank You!

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.

Our service provider Leo was so efficient and explained everything to where I understood the why to diagnose the issue. Once diagnosed and part ordered leo was very punctual and installation was completed everything was re tested and was done flawlessly

AC Unit would not cycle off, intake had a shrill sound. Repaired both with next day service. They are the best of the best.

Best service Ive had over the years. Quick, responsive, and professional. Theyve installed a new unit for me and much more. Would recommend to anyone who needs AC services.

Professional and fast. The work exceeded expectations and Alex is not your average guy. He goes way beyond to make sure you are well cared for as a customer. Our service was a full replacement and the pricing was extremely competitive for the quality. It’s hard to find good people that are providing exceptional service at a fair price - Guardian hit all the checkboxes for me and I will definitely be a repeat customer for years come. Thank you Alex and the technicians for your great service!

We have been dealing with horrible air companies for years who never can find the issue. Armando found it within 30 minutes! The nicest, most thorough company we’ve had. We will be staying loyal to them!

Guardian is by far the most professional and effective HVAC service I’ve ever worked with . They creatively solved a problem that other companies couldn’t fix for years!
They are excellent communicators, easy to work with and reasonable.
