Tom’s grandpa wasn’t sure what to think when his grandson tried to explain ordering things from an HVAC online store. He knew if he wanted to get some new HVAC air filters, he had to drive to town where there was an HVAC store. They had been talking about air filters and indoor air quality when this came up. Tom had gone to visit his grandpa because he wasn’t feeling well. He lived about 2 towns from him and was the closest relative around. So, he made plans to drive there to check on him and report back to his mom. Tom’s mom lives abroad, and she was feeling so bad she wasn’t there for her dad. But, Tom put her mind at ease and planned the trip to go see his grandpa. When he arrived, his grandpa was doing much better since he had been to the hospital. The doctor had treated him for allergies and said it was time to check on the indoor air quality. This meant replacing the air filter, and perhaps adding an air purifier in his home. Tom’s grandpa told him this and said he was planning to drive to town when he was feeling better to get into the car. That way, he’d go to the HVAC store to get new air filters and also learn more about air purifiers. Tom said there was no need to wait since it was easy to place an order online and also learn about air purifiers. He searched for the best HVAC companies around, and found one with a good website. There, they placed an order for air filters and also read up on air purifiers.
