Choosing a commercial rooftop Heating & A/C unit for hair salon

I recently decided to purchase a commercial building in order to open a hair salon. At that time, I was splitting hair out of a room at my home & the situation wasn’t ideal. I was hoping to give more parking, rent spots to other stylists & have sufficient space for a tanning bed & manicure/pedicure stations, but my budget was rather limited, and since my husband & I are both quite handy, I looked for a building in a fantastic location that was in need of some upgrades. I was able to pay less because the building needed a good deal of work & remodeling. My husband & I had no concern ripping out the floors, replacing windows, updating the plumbing fixtures or installing sinks. However, I decided to hire a professional for help with the heating & cooling system. There was an seasoned & honestly big packaged Heating & A/C unit taking up a lot of space in the parking lot. It was located in a way that made it honestly susceptible to clients hitting it with their cars. The outer cupboard was dented & rusted. When the Heating & A/C business ran tests on the equipment, he recommended replacing it entirely. He said I’d end up saving money by installing a more energy efficient system. He also requested that I switch to a commercial rooftop unit. This type of plan combines heating & cooling into a single piece of unit that is installed on the roof. It frees up costly space, never detracts from aesthetics & is not accessible to vandalism. If the Heating & A/C unit requires service, there is no disruption to bi-weekly operation of my business. Plus, with the heating & cooling unit up on the roof, the sound levels are kept to a minimum.
