Central Heat/Air for older home in St Pete Florida

[Kathleen1960]

We are having a problem keeping our 1920 bungalow cool in these hot summer months , even though our home has a brand new central/heat air system in our 1200 sq ft bungalow. The cool air is coming out of the wall vents and the house will cool better at night, but during the the day it will not get about 78 degrees in home. We just installed R-30 insulation in the attic, which seemed to show minor improvment in the cooling , but this was limited to the main area of the house. The master bedroom which has a raised ceiling is especially warmer than the rest of the house. The air-condiioning people have been out and have not found any problem in the central air system.

1920’s houses were built before insulation was a serious thought. Air conditioning didn’t come along for another 40 years for most homes.

The lesson here is that insulation is a real requirement to make cooling units work better without having huge electric bills from huge air conditioners. Another lesson is that square feet of floor space has little to do with air conditioner size and square feet of walls, windows, and ceilings with insulation has a lot more to do with it.

You now have the choice of continuing to spend large electric bills with a larger air conditioner to cool your home, or to spend a little on a lot more insulation to help your limited-size air conditioner do enough cooling.
