Cube Heating and Air recently installed a new geothermal unit in our home, and we couldn’t be happier with the experience. Their team arrived when they said they would, which went a long way in building our trust. Throughout the entire process, they kept us informed, communicated clearly, and made sure we felt cared for every step of the way. The consistent communication and reliability really set them apart. We highly recommend Cube to anyone looking for professional, trustworthy HVAC service!

Freddie fixed my home HVAC in June 2024. My unit was very old and poorly maintained by the previous resident. To make things worse, a vent cleaning company severely damaged it. Freddie really knows his stuff. He diagnosed the issue correctly and patiently explained everything that wasn’t functioning properly, the pros and cons of repairing versus replacing the unit. I chose to get it repaired instead of replacing. Freddie spent the entire day working on it, took everything apart, did a deep chemical wash to remove dust left from the botched vent cleaning, and replaced some completely damaged parts. Since then, my HVAC has been running smoothly. I am glad I found his contact at the right time.
We feel soooo lucky to have found Freddy! When it comes to repairing/maintaining appliances, you have to put so much trust (and oftentimes money!) into the hands of experts you don't know. Don't worry about doing that with Freddy. He patiently spent time with us making sure our heat pump was in good shape and educating us on the ways user-error could have been contributing to our perceived issues. His prices are honest and competitive and his expertise is invaluable. We joined his VIP service to get bi-annual maintenance checks, discounted repairs, priority service, and maintenance reminders. Highly recommend!
We had CUBE Heating & Cooling out after another company was unable to properly fix our HVAC issue. Freddy was punctual and communicated everything he needed to do to diagnose the issue. Freddy is very knowledgeable and was able to answer all the questions we had. We would definitely recommend CUBE heating & Cooling to anyone looking for an honest HVAC company.
It is totally obvious why this company has 5 stars. They are honest, efficient, fair, and hard working. AC busted on a weekend, they showed up at 3 PM on a Sunday and in a couple of hours, with some good old fashioned sweat equity, we were up and running. Can't thank you enough and I will be a regular going forward. No more getting overcharged by a company that is too busy to talk to you. I want personal service, and I get it at CUBE!
Had an unfortunate issue with our A/C ( of course on a Saturday am on a holiday weekend). Called Cube and Freddy was friendly, gave some great advice and was able to get out to our home that very day. Freddy was extremely knowledgeable, polite, speedy and easy going. Reasonable rates and trustworthy. Will be signing up for a maintenance plan with Cube and will be sure to recommend them to friends & family!
Need a knowledgable, reliable, and trustworthy HVAC company for a heating or cooling issue? You can count on Cube! I met Freddy and Joe over the summer to resolve an AC issue, and when my furnace suddenly stopped working in the dead of winter, I called Freddy and he came same day, diagnosed the issue, and expedited everything, including he and Joe working on a Sunday to do the replacement and restore our heat. Best service provider I’ve ever worked with for home maintenance.

I called 10 companies at 9pm because I had AC issues, companies that claimed that they were 24/7. None of them wanted to assist same day, until I called Cube.
