Once in awhile my husband, son, and I take a nice vacation. The most recent vacation we took we stayed in a resort hotel. The resort was beautiful. Our room was huge and amazing. It had all the newest and most modern amenities. The bathroom had a beautiful shower and modern jetted tub. The kitchen area had a stove, oven, microwave, and full size refrigerator. The living room had a beautiful, modern, gas fireplace. It also had the controls to the heating and cooling system. The thermostat had a lot of options on it, especially for a thermostat in a hotel room. The best thing about this heater and air conditioner system was that it was really to use. It also kept the rooms the perfect temperature. Even when we wanted to use the fireplace, the air conditioner kept the room cool. I love how well the air conditioner worked. Staying at this hotel was the very first time in my life that I have slept in a hotel room and stayed comfortable through the night. The thermostat really kept the temperature perfectly comfortable. Even when we went swimming we adjusted the temperature first so that we would not freeze when we got back to the room. When we got back to our room and changed we could adjust the air conditioner and it was back to perfect quickly. I love the HVAC system in our hotel room. I wish every single hotel that we stayed at had air conditioning and heating systems that worked as well as this one.
