Our brother-in-law has been working every single weekend for the last month and a half to put in a new HVAC system for both the first and second floors of our home. The temperature has started to get chillier with the low last night being 48°F and the low going to be down around 46°F again tonight. The air conditioning has been running on both floors for the last few weeks with the gas line being finished last weekend for the upstairs unit. We flipped the heat on for our son upstairs yesterday. However, the gas line for the downstairs unit (where our Master Bedroom is located) just got finished this morning.
Now, this evening, we have heat for both upstairs (where our son sleeps) and downstairs!
