Long story short you have to have air getting sucked out as you blow it in. We have too much air getting blown in and not enough getting sucked out. So we don't have enough returns and home isn't heated or cooled properly. Shamrock knew this because CFM's are a simple math problem. They cut corners so badly and tried to do it all cheap as possible. They came back SO many times to "balance" the system. When all the while they knew it wasn't going to work. We could've balanced it 1 million times and it still would not have worked. Because the math was off. BUYER BEWARE! And yes there are a couple good reviews. But do you want to take that risk on your home? I wouldn't. Not on Shamrock. Never again,

Before I start, please know it's rare for me to write a review for a company, but every once in a great while, I come across a company who truly deserves a positive review. Jonathan's Heating & Air Conditioning Company is one of those rare companies that truly deserves a great review. On May 1, 2024, I had a company (not Jonathan's, as I hadn't heard of them yet), install a brand new HVAC unit in my home. In mid-June of this year, 2025, my just over 1 year old HVAC unit was only putting out "fan air", not "air conditioned" air. (Of course, the warranty expired exactly 1 year after installation). I put in a claim with my home warranty company. After several days of them not being able to find a company to come to my home to repair the unit, they finally gave me the option to find my own licensed technician to come out and diagnose the problem. I called the original installer, figuring he could easily diagnose and repair the problem, but he said he was booked out for the next 5 weeks!! So, I called many large and small companies that advertised that they can install and/or repair HVAC units. The earliest any of them could come out was about 10 days. Not only that, but most of them said they would not help me answer the questions required by the home warranty company about the HVAC unit's issues, so that I could (hopefully) be approved for the repairs & get reimbursed later. After many, many calls, I came across Jonathan's Heating & Air Conditioning Company. Not only were they the least expensive price I was quoted by any of the other companies I called, to come out & diagnose the problem, but they were willing to help me submit the needed answers to the questions required by my home warranty company, so we could proceed with the repairs once the problem was identified. When I spoke with Alix, in the office, she heard the desperation in my voice. She said they would send out one of their techs the very same day!! Their tech, Joe, did indeed come to my home that same day as promised. He diagnosed the problem. He took pictures and a video & he sat with me while I answered all of the home warranty company's questions and submitted the pictures, (they do not accept videos), on their portal. The home warranty company called Joe, while he was still at my house & said they wanted more pictures. Joe took more pictures and I submitted them. His patience level was nothing short of exceptional while we waited for the warranty company's decision. They did not make a decision that day. In fact, the home warranty company took days to make a decision. Alix, in the office, was kind and compassionate. She knew my cat & I were suffering on the 100 degree days we were having in NJ. Joe, their technician, was just as kind and compassionate as Alix. During the waiting period (because of the home warranty company's delay in reaching a decision), Alix and Joe continued to have good communication with me to see if there was anything else needed by the warranty company. On two occasions, I spoke to the owner, Jonathan. He explained in more detail, but in layman's terms that I could understand, exactly what the problem was for my own knowledge and in case the warranty company asked me any additional questions. The whole experience with Jonathan's Heating & Air Conditioning was exceptional. The pricing, the quality of workmanship, the communication, the willingness to answer questions I had & the willingness to help me answer the home warranty's questions, etc., by far exceeded my expectations. I would, without reservation, recommend them to my family and friends (and anyone else reading this review), should any of you have any HVAC issues.

Of course since the fan would fix the problem we opted for the fan. Came back with the fan 5 days later and during installation said, oh you could have a carbon monoxide if you don't get a new furnace. Really??!!! Of course we don't want a carbon monoxide leak! So what, install the fan for $1200 and then a whole new furnace weeks later??? Why put the fan in in the first place if we're going to have to get a new furnace??? And then they charged us for the fan installment after never putting it in!!! Disputing the credit card charge and will never recommend... just the opposite!

I'll definitely be reaching out to him for any future HVAC needs. If you're looking for someone reliable who actually cares about doing the job right, call this company!

Once on site, they diagnosed the problem immediately, showed me exactly what was wrong, and explained everything in clear, simple terms including pricing. The repair was done quickly, and they made sure the system was running perfectly before leaving. Clear, professional, and genuinely helpful. Highly recommend Dean's Services!

They recently started offering Plumbing services and my first experience was so-so. As part of the maintenance plan, you now get a plumbing inspection every year. The plumber who came out today was very nice but missed an issue that I pointed out to him. He did have his Master Plumber that was hiding in the truck (? Seemed odd haha) come take a look. There was some estimate issues leading me to think the installation of a toilet would be $1,000 for labor alone. However, the owner was quick to rectify and look into the issue personally once he became aware, and was very open to feedback on how to make the estimates more clear. I would still like to see them itemize the cost of materials in the future, but it seems to be something at least on his radar. I would give this company a chance if you're having issues. They seem to truly want to do the right thing by the customers and their employees, which is important.

Our 25-year old HVAC system was hanging on out of sheer loyalty... but the time had come to bite…read morethe bullet and purchase a new central air system. For those of you that have not priced these things out before, quite a bit has changed over time...like the cost! Also, technology has moved on as well, so it's virtually impossible to replace "just the condenser" without all the additional furnace components...they simply won't work together. We called several HVAC contractors...one of them being the large energy company we all know in this area. They came in and did their inspection and were very professional. But their price was 50% higher than the local competition. Yes you read that right!! I wasn't concerned about the "big guys" doing it right, since they are our current utility firm and we have appliance contracts through them. But in light of these tough economic times, I really wanted to give it to a small business. I just wasn't sure how well they would stand behind their work and whether they would do it right the first time. I did research and found two other options. The one that really stood out was AAA Comfort Air in Cream Ridge, NJ. They had over 95 five-star reviews, and although anyone can fake a review, I still felt compelled to do my due diligence. I set an appointment for Emil (the owner) to come in and assess the situation. He was professional, took his shoes off before entering (not at our request), and clearly laid out what was needed and NOT what was most expensive. As a matter of fact, he recommended options that were less expensive vs. those that would simply feed his wallet without added benefit to us. His demeanor was polite, knowledgeable, and he took the time (over 1-hour) to really explain everything without pushing for the sale. Additionally, there are some unique challenges in our home that require minimal dust due to some family health issues and he offered to put up plastic to separate the rooms to ensure a clean work environment. Well, much to my surprise, Emil, came back with an estimate that was truly outstanding vs. simply "competitive". Likewise, his firm provides a 3-year parts and labor warranty (not an option...he just provides it) along with the condenser manufacturer's 10-year. The others only offered 1-year.... that in of itself really resonated with me! We decided to move forward, and I have to say, we made the right decision. Emil and his team were outstanding. They arrived on time, ready to go, and their work was outstanding. Everything was done in one day, with a clean install and a fully working system. Look, HVAC replacement won't make your home look nicer, but it surely is important. No one wants to spend that kind of money unless they have to. Emil and his team were not only very competitive, but they delivered on their promises and were very customer focused. If you are seriously considering a project like this, you need to consider AAA Comfort air. They deliver on their promises and care about their customers. They go above and beyond and deliver with an eye towards balancing price with efficiency. We highly recommend them and you should absolutely include them in your decision-making process. They truly are "AAA".
