Demystifying Air Conditioning: Evaporator and Condenser Coils

The evaporator and condenser coils in your air conditioner aren’t coolness generators, per se. An A/C is actually a heat mover. It extracts heat energy from the air inside the house, moves it outdoors, and what’s left behind is simply the absence of heat. The evaporator and condenser coils are critical components in the closed-loop refrigeration system that gets the heat-moving done efficiently and effectively.

Attic Insulation: A Surprisingly Important Part of Year-Round Efficiency for Florida Homeowners

attic insulation Heat energy is always in motion, and a proper layer of attic insulation helps stop it. During winter, warmed air from the furnace escapes into the attic by conduction or radiation. In summer, an overheated attic transfers heat into living spaces below. In both seasons, operating costs increase.

Upgrading insulation in the attic is one of the most direct ways to lower your monthly utility bills, as well as improve indoor comfort in all seasons. Here are the most common insulation options:

Fiberglass Batts

Packaged in rolls pre-cut to fit into the space between the attic joists, fiberglass insulation is the least expensive and easiest way to upgrade attic insulation. Insulation’s effectiveness in resisting heat transfer is rated by its R-value. Standard fiberglass batts have an R-value of 3.2 per inch.

Fiberglass batts are most appropriate where:

  • The attic has standard 16- or 24-inch joint spacing
  • There are few obstructions like pipes and recessed ceiling lights to work around
  • Sufficient room is available to move around comfortably during installation
  • Do-it-yourselfers wish to handle the job themselves

In Florida, the Department of Energy recommends insulating to an R-value of R-30 to R-60 in the attic. This means a depth of 12 to 18 inches of fiberglass.

Cellulose Loose Fill

Composed of tiny pulverized bits of paper and cloth treated with fire-retardant. Blown into the attic by air pressure through large hoses, cellulose looks like a layer of fresh fallen snow and offers excellent coverage and a higher R-value of 3.8 per inch.

Cellulose is a good choice where:

  • The attic already has an existing layer of insulation you wish to add to
  • Attic space is cluttered with obstructions or has many odd-shaped nooks and crannies to fill
  • Headroom in the attic limits movement
  • Your budget provides for professional installation

With its favorable R-value and improved coverage, the recommended depth of cellulose insulation in the attic is 8 to 16 inches.
