Poor Attic Insulation Results in AC Ineffiicency

Dealing With Poor AC Efficiency? Check Your Attic Insulation

July 8, 2025

Is your air conditioner constantly running, but your home in Hobbs, NM, still feels warm and stuffy? Are your energy bills climbing month after month with little improvement in comfort? These are signs that your AC system may not be the problem. Inadequate attic insulation could be the real culprit. Poor insulation allows cooled air to escape and outdoor heat to pour in, forcing your air conditioner to work overtime and costing you money. Here’s how attic insulation impacts AC efficiency and what you can do about it:

Heat Enters Through the Attic

During Hobbs’ scorching summers, attics can reach well over 130°F. If your attic lacks proper insulation, that heat seeps into your living space, making it harder for your AC system to keep your home cool. Without a thermal barrier, your air conditioner must run longer and harder, reducing efficiency and shortening its lifespan.

Cool Air Escapes Too Easily

Insulation doesn’t just block heat from entering. It also keeps your conditioned air inside. Inadequate attic insulation allows cooled air to rise and escape through the roof. This constant loss creates uneven temperatures and discomfort throughout your home, especially on the upper floors or rooms directly beneath the attic.

Energy Bills Continue to Rise

When your AC system works double-time to compensate for poor insulation, your energy bills reflect it. Homeowners in Hobbs, NM, often assume they need a bigger or newer air conditioner when, in reality, improving attic insulation could significantly reduce costs and increase indoor comfort without replacing equipment.

Upgrading Attic Insulation is a Smart Investment

The good news is that resolving this issue is effective and affordable. Adding or upgrading attic insulation, using materials like fiberglass, cellulose or spray foam, creates a better thermal envelope. This simple improvement enhances energy efficiency, reduces wear on your AC system and improves comfort throughout your home.

Don’t let poor insulation sabotage your AC system’s performance. If you’re a homeowner in Hobbs, NM, schedule an attic inspection today by contacting I.T.S. Refrigeration & Heating, Inc. to protect your comfort, lower your energy costs and extend the life of your air conditioner.
