Cleber was awesome, very professional, honest and got us taken care of. We had a different company come out before but something felt off so we called Unlimited. They were amazing! Trust worthy and thorough. We would definitely recommend Unlimited!

AMAZING SERVICE! I spend a lot of time doing my research before contracting someone to do an expensive project like heating and cooling. They are honest, fair priced and if you have issues they will come out quickly and resolve the issues. You don’t need to look at any of the 1-star reviews because this is definitely a 5-star company.

Hope

My first interaction with Frank was amazing. He was courteous and explained the service procedure. I received same day service which was a bonus. I received a text/email confirmation of my appointment. The best part is the text message had the name and a picture of the person who was coming to service my home!!! I loved, loved that. Once the job was completed I received another text message. I was able to pay my invoice via a link to my email address. Convenience and safety are spot on and is a plus, plus in my book. I received a call from Frank and he explained the issues that needed to be addressed. The pricing was affordable. Great Great Company/People.

B Us

Frank (owner) was highly recommended to me as a professional with high quality standards, after working with him I agree. He was very responsive to my questions and my requests (no matter how outlandish, keeping old equipment that I had replaced on my own throughout the years). We had a leak in our evaporator coil as found/detected from our yearly AC check (through another company) but decided to get a second opinion to make sure. We contacted a family friend and he recommended Frank. Frank reached out to me immediately and we were fitted into his schedule the next day. Frank confirmed the leak and we discussed solutions and options with him. He gave us price ranges for our situation. After talking about it overnight we decided that the age of our HVAC system dictated that we should go ahead and replace the entire system. His price proposal and details of what the job would entail/require put us at ease as he stayed to answer all our questions and addressed our needs. He was very easy to talk to and he always responded to texts even on the weekends. Once he started the job he stayed in contact with us directly as his team completed the job of disassembling the old AC condenser unit, evaporator coil and furnace along with installing the new replacement units. After the installation was completed Frank scheduled the code compliance officer to visit our home and make sure everything was in compliance with city ordinances. We are very happy with Frank and his team and would highly recommend them to other's including my friends and family.
