When did this air conditioner get old?

My family owns and operates a afternoon spa, where clients come to care about relaxation and pampering.  The two of us job honestly difficult to create a soothing environment. Soft lighting, cascading water, gentle songs, and calming scents all help to combat stress and promote a sense of peace and wellness.  The spa includes treatment rooms for massage therapy, facials, body wraps, manicures and pedicures. The two of us offer several bizarre hot tubs, saunas, and an indoor swimming pool. Each space has identifiable   requirements and challenges. The two of us deal with problems with body odors, mold, mildew, dust, and excessive humidity. Cleaning is an ongoing responsibility and a priority. The operation of the heating, cooling and ventilation systems is essential to the comfort, health, and budget of the facility.  When the building was designed, the people I was with and I consulted with a licensed Heating, Ventilation, and A/C corporation to determine the best type of system for our requirements. The Heating, Ventilation, and A/C corporation recommended a ducted heating and cooling system which allows for zoned control.  The two of us also incorporated a heat recovery ventilator to introduce fresh air and expel excess humidity. Each space within the facility is equipped with an independent control unit, which allows us to customize both temperature and humidity levels. It’s often necessary to supply simultaneous heating and cooling to rooms which are side by side.  Because of this, insulation and vapor barriers were an essential feature of the building design. Although the investment into a top-of-the-line Heating, Ventilation, and A/C system was rather costly, more precision control has saved a good deal of money on daily utility bills. Plus, our clients would not be gratified with anything less than ideal comfort and air quality.
