FAQs About AC Installation & Replacement

How Long Does AC Installation Take?

Most residential installations are completed within one to three days. Complex installations requiring significant ductwork modifications or electrical upgrades may require additional time. We provide accurate timeline estimates during the initial consultation.

What Size AC System Does My Home Need?

System sizing depends on multiple factors, including square footage, insulation quality, window placement, ceiling heights, and local climate. Our technicians perform detailed load calculations to determine the appropriate capacity for your specific home.

Should I Repair or Replace My Current AC System?

If your unit is over 12 years old and repairs are becoming frequent or costly, replacement may be more cost-effective. In Memphis, older systems often struggle with energy efficiency during humid summers, leading to higher utility bills. Our team provides a clear performance assessment and cost comparison so you can make an informed decision without pressure.

What Maintenance Does a New AC System Require?

Regular filter changes, annual professional maintenance, and keeping outdoor units clear of debris help maintain efficiency and prevent premature failure. We provide detailed maintenance schedules with every installation.

Do You Offer Emergency AC Replacement Services?

Yes, our team remains available 24/7 to handle cooling emergencies, including complete system failures requiring immediate replacement during extreme heat.

Is My AC Short-Cycling Because It’s Oversized for My Memphis Home?

If your air conditioner is turning on and off every 5 to 10 minutes—a process called short-cycling—there is a high probability that the system is oversized for your home’s specific square footage and layout.

In our hot, humid Mid-South climate, an oversized unit is more than an efficiency issue—it’s a comfort problem. When the system is too large for the home, it cools the air quickly but doesn’t run long enough to remove the city’s heavy humidity. As a result, your home can feel clammy or muggy even when the temperature seems right, while short run times put extra wear on components and shorten the system’s lifespan.

Typical signs your system may be oversized include: 

• Rooms feel humid or sticky despite the thermostat reading the setpoint
• Large temperature swings throughout the home
• Frequent, noisy starts and stops
• Higher-than-expected energy bills for short cooling cycles

Many older homes in Midtown, East Memphis, and surrounding neighborhoods have been upgraded with new windows, added insulation, other energy-efficient improvements, or even previous AC upgrades. However, installing a new AC based solely on the size of the old unit can result in a system that’s too powerful for your more efficient home. 

The most reliable way to ensure proper sizing is with a Manual J load calculation performed by our licensed Memphis AC replacement contractors—rather than simply matching the old unit.

I Have an Older Home in Memphis – Can My Ductwork Handle a High-Efficiency AC?

In many historic Memphis neighborhoods—from the bungalows of Midtown to the ranch homes in East Memphis—older ductwork is often narrow, leaky, or fragile. Modern high‑efficiency systems move air differently to maximize cooling, dehumidification, and energy savings. That means your new AC may be capable of excellent performance, but your existing ducts can limit comfort and efficiency if they are not evaluated.

Key things to know:

• Airflow Requirements: High-efficiency systems often require larger or smoother ductwork, so the new blower can “breathe.” If ducts are too small or restrictive, a SEER2 AC unit can develop noisy vents, frozen coils, and unnecessary wear on your new investment.
• The Memphis Humidity Factor: Because our summers are notoriously swampy, proper airflow is critical. If your ducts leak or aren't insulated correctly for the high static pressure of a new blower, you could end up with condensation issues in your attic or crawlspace.
• Static Pressure Testing: Before installation, a qualified technician should perform a Static Pressure Test. This measures the resistance within your ducts. Think of it like a blood pressure test for your home; it tells us exactly if your ducts can handle the new AC.
• Variable Speed Motors: Modern high-efficiency units often use ECM (Electronically Commutated Motors). If these motors encounter restrictive, old ductwork, they will ramp up to overcome the resistance. While this maintains airflow, it can cause the motor to burn out prematurely and increase electricity bills,

Outdated ductwork doesn’t mean your home can’t enjoy a high-efficiency AC. A licensed Memphis AC replacement contractor can inspect, reinforce, or modify your ducts to ensure optimal airflow, comfort, and energy savings. Skipping this step can result in uneven cooling, higher bills, and premature wear on your new system.

Is Upgrading to a High-Efficiency AC Worth It in Memphis?

Yes—energy-efficient air conditioners are generally worth the investment in Memphis, even with MLGW’s relatively low rates. With the final phase of the 12% MLGW rate increase taking effect in January 2026 and our long, humid summers, efficiency isn’t just a luxury—it’s a smart financial and comfort decision.

Why efficiency matters:

• Lower energy use: Even at below-average rates, Memphis homes consume a huge amount of electricity from May through September. Upgrading from an older 10–13 SEER unit to a high-efficiency SEER2 system can cut cooling-related energy use by up to 40%, especially for units over 10–15 years old.
• Variable-speed compressors: Unlike older units that are fully “on” or “off,” these efficient air conditioners run at lower speeds for longer periods, removing more humidity and making a 75°F room feel cooler and more comfortable.
• Lower starting current: High-efficiency units draw less power when starting, reducing the chance of tripped breakers during Memphis heatwaves or stressed-grid conditions.
• Better comfort and quieter operation: You gain improved humidity control, quieter cycling, and more consistent cooling during the intense 95°+ Memphis summer days when the AC runs almost nonstop. 

The most cost-effective approach is to have a licensed AC installation contractor look at your existing system age, size, ductwork, and past bills, then run the numbers on how quickly a new high‑efficiency unit could pay for itself in your home. Be sure to ask about federal tax credits and rebates to help offset the initial cost.
