How Hot Georgia Summers Expose HVAC Problems Missed During Home Inspections

Description: Georgia's scorching summers reveal HVAC issues that standard inspections may miss. Learn how to protect your home and investment in Atlanta, Marietta, and surrounding suburbs.

Introduction:

If you're buying or selling a home in the Atlanta metro area, HVAC performance can make or break your summer. But here's the kicker: many HVAC issues don't show up during mild weather home inspections. As temperatures soar in Georgia summers, those minor inefficiencies become major problems.

From Marietta to Sandy Springs, Decatur to Kennesaw, Georgia homeowners are learning the hard way that a basic home inspection might not fully test the AC system under stress. That $15,000 HVAC replacement? It could be hiding behind a clean-looking vent.

In this post, we'll explore how Georgia's summer heat reveals hidden HVAC defects, why standard inspections sometimes fall short, and how to truly protect your comfort and your wallet.

Why Georgia Summers Are the Ultimate HVAC Test

Georgia’s climate is known for:

• High heat (mid-90s in peak summer)

• Oppressive humidity

• Long cooling seasons (May through September)

These conditions push HVAC systems to their limits, often revealing:

• Weak compressors

• Undersized units

• Improper refrigerant charge

• Poor duct design

A system that seems fine in April may struggle by July.

Common HVAC Issues Missed During a Typical Home Inspection

1. Undersized or Overworked Units

   • Older homes in Roswell or Decatur often have outdated sizing.

   • AC runs constantly, never reaching desired temps.

2. Improperly Charged Refrigerant

   • Only noticeable in full operation mode.

   • A unit might cool slightly in spring, but fail to keep up in July.

3. Leaky or Poorly Insulated Ductwork

   • More common in attics or crawl spaces.

   • Wastes energy and lowers airflow.

4. Clogged Drain Lines or Dirty Evaporator Coils

   • These may not be visible without removing access panels.

   • Can cause overflow or mold growth in summer.

5. Thermostat Misplacement

   • Placed near windows or kitchens, misreads home temperature.

6. Disconnected or Improperly Installed Returns

   • Especially common in DIY renovations.

What a Standard Home Inspection Covers (and What It Doesn’t)

In Georgia, home inspectors are bound by SOP (Standards of Practice) defined by organizations like InterNACHI and state guidelines.

A standard HVAC inspection includes:

• Checking if unit operates

• Visual inspection of accessible components

• Noting age and condition

What it doesn’t include:

• Load calculations

• Deep performance testing

• Full seasonal cycle assessment

• Checking duct balance or airflow

Why You Should Request a Full HVAC Evaluation

A dedicated HVAC performance inspection might include:

• Temperature differential testing

• System pressure testing

• Refrigerant level verification

• Full airflow analysis

• Static pressure measurements

These inspections can:

• Reveal hidden efficiency issues

• Help you budget future upgrades

• Provide negotiating leverage during a sale

Real-World Examples in Atlanta

Case 1: The "Brand New" AC in Sandy Springs Looked perfect during inspection. But unit was undersized for the home's square footage and orientation. Buyer ended up replacing it within 6 months.

Case 2: Duct Disaster in Kennesaw Seller did DIY work in attic. Half the vents were disconnected. Inspector noted airflow was low, but buyer didn’t follow up. Full re-ducting cost $6,000.

Case 3: Mold in the Coil in Decatur Home passed inspection, but no one opened the air handler. Mold was growing in evaporator coil. Required professional cleaning and a UV light system.

Georgia Code and Standards to Know

• Georgia State Minimum Standard Energy Code (based on 2015 IECC): Requires proper HVAC sizing via Manual J.

• ASHRAE 62.2: Ventilation standard for indoor air quality.

• EPA HVAC Efficiency Guidelines: For SEER ratings and refrigerants.

Tips for Buyers and Sellers in Georgia

Buyers:

• Ask for the system age and SEER rating

• Hire an HVAC specialist if the home is 15+ years old

• Check utility bills for high summer costs

Sellers:

• Service the system before listing

• Provide HVAC documentation

• Consider upgrading thermostat or filters for added value

FAQs: HVAC Problems and Georgia Summers

Q: Should I test the AC again before closing? A: Yes, especially if your inspection happened in cool weather. A quick run test may not reveal stress faults.

Q: How long should an AC unit last in Georgia? A: 10–15 years is typical, but climate stress shortens lifespan.

Q: What if my HVAC is working but not cooling efficiently? A: Could be airflow issues, low refrigerant, or bad duct design.

Q: Does my inspector check refrigerant charge? A: No, only licensed HVAC techs can do that under EPA law.
