Dad was a bit skeptical when my sister and I told him we wanted to live together. Though he understood our motivation, I guess he was worried we’d end up on each other’s throats. My sister and I love each other, but we’ve also had instances of intense sibling rivalry. We reminded dad that those incidents were when we were in our crazy teen years. Now, we are adults in our 20s and have a better relationship. Dad was still skeptical, so he insisted we hire a lawyer to draw up an agreement. See, my sister and I decided to buy houses together so we can come up with the downpayment faster. It was taking too long to do so as individuals, so we thought of teaming up to make the process and saving easier. After we bought the first house, we had to find a local HVAC company to come and install a new HVAC system. The house was excellent, and had the right amount of space. But, it didn’t come with any heating or cooling system. Each homeowner was in charge of picking out the right HVAC system for our home. Dad agreed we should consult a HVAC company. And he also insisted we only go for the best HVAC brands that are long lasting. Nowadays there are many HVAC systems in the world, however, there are some brands that stand out. Not only do they have a reputation for making the best heating and cooling units, but they also have solid warranties. We agreed with his assessment and began researching the best HVAC brands in the market.
