On Tuesdays and Wednesdays, I have the day off work. Unfortunately, I have to work every weekend. At least my company pays me very well, for being available to work every weekend. I even receive a three hundred dollar bonus on each paycheck, for working every weekend shift. My girlfriend gets upset when I can’t hang out with her friends, but she likes me to bring home the bacon. Last Tuesday, my girlfriend was working all day and I planned to clean up the front and back yard. I put gas in the mower, and had the weed whacker ready to edge the sidewalk. I had my favorite music playing on the bluetooth headphones. That’s when I heard a beep in my ear. It was an alert from smart thermostat application on my cell phone. The smart thermostat app alerts me if anything strange happens with the HVAC unit. The alert told me that the indoor temperature was three degrees higher than the suggested temperature. Since I was at home, I walked back in the house to inspect the issue. In the ten minutes I had been outdoors, the indoor temperature went from 72 degrees to 75 degrees. I put my hand up to the HVAC vent, and I couldn’t feel anything at all. In fact, I didn’t hear the HVAC unit running either. With the A/C not working, I had no choice but to call the local contractor for assistance. We barely know anything about HVAC unit, which is the exact reason we chose to buy a smart thermostat.
