Could not be happier with their service!
Top to bottom \- If I could give 6 stars, I would. I replaced two systems and a hot water heater. They worked with me on selection and pricing every step of the way in a patient and understanding manner. Installation was smooth and everyone was so kind and considerate. Again, I couldn't be happier.

HVAC Unlimited Is Awesome
Installation crew created a calm atmosphere. They were very knowledgeable and were able to answer any questions that we had. They kept our home clean on a rainy day. We have used HVAC Unlimited for years (2nd furnace/AC they have installed for us) and have never had a bad experience (installation or service).

Exceptional Service
I had HVAC Unlimited do my upstairs air handler and outside compressor unit replaced some years ago and the experience so impressed me that I decided I would ALWAYS use them when I had the need. Recently, I decided it was time to replace my downstairs air handler and compressor and called. They gave me a competitive price, offered me options and worked with me to tailor the solution to my needs. There was no pushy upselling for additional services, equipment or supplies. They scheduled my installation promptly, showed up on time and delivered exactly what they said they would. The two techs that came out took good care of our house, kept the worksite clean and left it cleaner. What impressed me the most was how knowledgeable, friendly and informative the techs were. They took as much time as I needed to answer all my questions. They even pointed out how they had fixed a few things not necessarily related to the installation that would make the system operation even better (clogged drains, etc.). It was clear from their comments that the techs really enjoyed working for this company and that they felt pride in their workmanship and loyalty towards the company. I am very happy with the products and services HVAC unlimited offers and I will continue to call on them for my HVAC and plumbing needs.

Happy
There was so much I didn't know about an HVAC system. The person who initially came to our apartment to see what we might need was very helpful, in that he showed me what was problematic and what could happen if it were not fixed. The two installers were very helpful also, especially Tre (I think that is the spelling). He was very patient and would not leave until we were 100% satisfied. Everything was cleaned up before they left. My wife and I are satisfied. Also, it was time to replace the HVAC and our apt. heats better now.

Multiple units installed and servicing that ends happily
Through several homes and complicated air handling and plumbing needs, HVAC Unlim has provided the best service and helpful insights. We've had them install six air handler systems that performed much better than the systems that were replaced (with noise remediation, as well). Very happy with them and we continue to recommend them.

4 Ton Install
The guys did a great job, kept the area clean, and did not make a mess. Only issue was the little communication, we had to constantly ask questions, simple questions like how is it going, when do you think you will finish, and how long for the house to cool off. There were no progress updates, and nothing about rating their work in social media. We do recommend HVAC Unlimited, the service was quick and professional. We'll call then again for future service.
