Why Your East Cobb AC Feels "Sticky" (And How to Fix Your Marietta Air Quality)
If you live in a modern home in Marietta, GA, you likely have a high-efficiency HVAC system designed to keep you cool. But during a typical Georgia summer, you might notice that even when the thermostat says 72°F, the air feels "heavy" or "sticky."
At Guardian Home Experts, we've seen a surge in calls from neighborhoods like Post Oak Square and Indian Hills where homeowners are battling high indoor humidity and rising energy bills. Here is the modern Marietta homeowner's guide to total home comfort.
1. The "Short-Cycling" Trap
Many modern Marietta homes are equipped with oversized AC units. While "bigger is better" sounds good, an oversized unit cools your home so quickly that it shuts off before it can finish the most important job: Dehumidification.
The Problem: Your AC runs for 10 minutes, hits the temperature goal, and stops. This leaves the moisture hanging in the air, leading to that "clammy" feeling and creating a breeding ground for dust mites and mold in your ductwork.
The Knight's Solution: We perform calculations to ensure your system is perfectly sized for your square footage. Often, a simple adjustment to your blower speed or the addition of a Whole-Home Dehumidifier can transform your home from a swamp to a sanctuary.
2. Georgia Red Clay & Your Sewer Lines
Marietta's beautiful oak trees and rolling hills are iconic, but their roots are constantly searching for moisture—especially in our dense "Georgia Red Clay."
The Problem: Modern PVC pipes are durable, but the shifting clay soil in Cobb County can cause "bellies" (sagging) in your sewer line. Once a line sags, debris builds up, and thirsty tree roots eventually find their way through the joints.
The Knight's Solution: We don't guess; we "see." Our plumbers use high-definition Sewer Camera Inspections to identify issues before they become a "main line backup" in your basement. If we find a problem, we offer solutions.
3. Indoor Air Quality (IAQ) in the 2026 Climate
With more people working from home in Marietta than ever before, the air you breathe matters. Modern, airtight construction is great for energy efficiency, but it traps allergens, pet dander, and VOCs inside.
The Problem: Standard 1-inch filters only protect the machine, not your lungs.
The Knight's Solution: We recommend the Guardian Air Scrubber. These don't just "catch" dust; they use UV light and ionization to kill viruses and bacteria on surfaces and in the air, keeping your family healthy through every Georgia pollen season.
