Mary was so excited about the new HVAC unit. She could not wait to use the application on her phone to reset the smart thermostat. The air conditioning system used new HVAC technology to help with indoor comfort. Everything was going smoothly because a friend had assisted her in narrowing it down to one among the HVAC brands. The HVAC professional who came to calculate that heating and cooling loads sealed the deal on the quality HVAC that she had in mind. The rest was up to the home service provider to install the air conditioner. Mary had not had the opportunity to involve herself with the a/c service providers in previous times. It was her first time visiting the HVAC company. She was so excited she could barely contain herself. The a/c worker that inspected her house told her that she would not go through the cost of laying new ductwork. The air duct was in good condition; it did not even have a single leak. After that, they went in search of furniture which was Mary’s favorite part especially since money was not a problem. However, she was going for just basic pieces. Her friend had advised her to do so because with time she would accumulate more things as time went by, plus her taste might change. Mary was afraid that she would forget the date for HVAC maintenance, but the HVAC technician told her it would come naturally plus she could always set a reminder. She could not forget to replace the ac filter since she was sensitive to changes in air quality. They also told her that the minute she noticed that there was something wrong with the unit she should call for ac repair immediately.
