Martins Mechanical Inc installs and services HVAC systems. In a 2025 review, a customer wrote that the company had installed an HVAC unit that "is only 7 years old," that a technician said the parts were no longer made and the unit needed replacing, and that another company cleaned it for $89 instead. In a 2023 review, a customer wrote that Martin's installed 2 mini splits 3 years earlier that "have never worked correctly," and that he refused to come correct the mistakes. In another 2023 review, a customer wrote that Rogerio installed a system that never worked and made an appointment 3 times to fix it without showing up. In a 2022 review, a customer wrote that a new HVAC system began freezing and leaking Freon less than two years after Roger installed it, that another company found a leak and said a new condenser was needed, and that Roger stopped responding. In a separate 2022 review, a customer wrote that Roger insisted on a 2-zone system whose ductwork proved inadequate, that he never pulled a permit, and that he replaced PVC that was not to code after being called out on it.

This company sent 3 people to take a look at my HVAC. The man who came, talked on the phone while doing the work. After a few minutes, with broken English, he told me, they don't make the parts anymore. It needs to be replaced. This HVAC is only 7 years old. I bought the unit from this company and the owner himself who installed it. He didn't tell me that the unit is actually very dirty. It needs to be cleaned. Instead, they wanted me to replace it. I called another company instead, charged me $89 for cleaning.
Martin’s installed 2 mini splits in our home 3 years ago. They have never worked correctly and we have spent thousands on repairs. He refused to even come and correct his mistakes. Doesn’t answer the phone. We are retired and continue to pay for his installation mistakes!!
The company is horrible. Rogerio installed a system that never worked. He made an appointment 3 times to come fix it but never showed up for any of the appointments after waiting for him for hours. He does not have any respect for time or for his profession. I doubt he’s even licensed . Should’ve done my due diligence before I hired him. Definitely NOT recommended.
Horrible experience
Our contractor used Roger to install our HVAC system and we subsequently used him to install additional duct work when we renovated our basement. Wow, what a huge mistake. As an amateur home owner, Roger seemed knowledgeable and was a nice guy. I wish I had gotten a second opinion. After he installed a brand new system, less than two years later we began having issues. Our HVAC system was freezing and leaking Freon. After he serviced it 2-3 times within a span of a couple months and our system died in the middle of the recent heat wave, we finally called to get a second opinion. The owner of Dover Mechanical identified a leak within 5 minutes or arriving at our house. As he began to repair it, he showed us that the damage was so bad from the attempted maintenance that we needed to get a new condenser. He walked us through what likely happened and showed us the damage in person. He said he had never seen anything this bad in his career. He also installed some additional protection because Roger recommended we have multiple zones and that was causing issues with our system. After reaching out to Roger several times, he just stopped responding. We’ve also had issues with airflow in our house with some rooms colder than others. All in all, trusting this group has led to problem after problem with a brand new HVAC system we just had installed by them less than 3 years ago.
