The winter season in St, but petersburg, FL is pretty underwhelming, and what I mainly do is focus on the cooling situation! I have a high velocity A/C plan that I use the majority of the year! The benefit of high velocity is the smaller than average ductwork.
The ducts are half the size, flexible, and can flex into the slats of an older home.
The air then abruptly whips around the smaller ducts to lower the temperature in minutes rather than hours! High velocity systems are more respected in hotter areas like Florida. The upkeep is pretty regular and the repairs are the respected ones that crop up. I appreciate having absolutely good A/C most of the year, for heating I don’t stress as much. I have a ductless furnace that I use in peak rooms of the household. The furnace is basically worn. I sleep, work, and piping is; Other than that I don’t problem myself with heat. In St. Petersburg our winter can start as late as January and quit as early as May. Having only a couple of months of chill isn’t so bad. The mornings get a little awful however during the afternoontime it warms up. I will say the biggest problem with the weather in Florida is deciding heating or cooling. Typically I start out with heating at night, in the early morning, change to AC, and then have to change back again in the Springtime. That means my St. Petersburg Heating and A/C corporation needs to clean and inspect both systems every time. I use them both most of the year, just heavily favoring the A/C plan.
