Selecting the Right Cooling System for the Gulf Coast

Choosing a new system involves more than just picking a brand; it’s about sizing the unit correctly for your square footage and matching it to Alabama's moisture levels.

• Humidity control. A system that is too large will cool your home too quickly and shut off before it removes humidity, leaving you feeling clammy. We perform load calculations to match the unit to your home’s specific needs.
• Energy efficiency. Modern units come with SEER2 ratings. We help you compare the long-term power savings of a high-efficiency model versus the initial cost of a standard unit.
• Corrosion resistance. Because we are close to the coast, salt air can eat away at outdoor condensers. We recommend units with protected coils and durable cabinets designed for our environment.

Types of Systems We Install

We work with reputable brands like Amana, Trane, and Carrier, which gives us the flexibility to match equipment to your property instead of forcing a one-size-fits-all solution. 

Our team installs:

• Central air conditioning systems
• Electric heat pump systems
• Ductless mini-split systems
• High-efficiency units for maximum energy savings

Financial Solutions for Your Comfort

A full system replacement is a significant investment. To help you plan, we offer financing options for qualified customers, including plans through partners like Wells Fargo. This allows you to spread the cost over time with manageable monthly payments instead of facing one large upfront expense.

When we provide a quote, we break down:

• Equipment choices and efficiency ratings
• The full scope of the installation
• The expected timeline for the job
• Total cost and monthly financing options

How to Know When It’s Time to Replace Your AC

At some point, every AC system reaches a stage where repairs start adding up and performance begins to drop off. In Semmes, systems tend to wear down a bit faster than in milder climates. Between long cooling seasons, heavy humidity, and frequent summer storms, your equipment works hard for most of the year.

Common signs that replacement is near:

• Frequent breakdowns. You’re calling for service more than once a season.
• Uneven cooling. Some rooms stay warm while others are freezing.
• Rising bills. Your energy costs are increasing without a change in usage.
• Constant running. The system struggles to reach the temperature set on the thermostat.
• Age. The equipment is 10–15 years old and uses outdated refrigerant.

When we inspect your AC, we’ll explain what we see in plain terms. If a repair is a viable option, we’ll tell you. But if replacement is the better long-term value, we’ll provide clear pricing so you can make an informed decision.

Local Knowledge Makes a Difference

Being a local family business since 1969 gives us a perspective that out-of-town companies simply don’t have. We know the neighborhoods in Semmes and the common issues that pop up here. We understand how a heavy afternoon thunderstorm can cause power surges that stress your AC’s electronics, and we know how the local pine pollen can clog up outdoor fins if they aren't maintained properly.

Our deep roots mean we are invested in the community. When you call Hembree Heating & Air Conditioning, you aren't reaching a national call center. You are talking to neighbors who live and work right here. We are licensed and insured, so every project meets the safety and code standards Semmes residents deserve.

FAQs

How long does an installation usually take?

In most cases, we can complete a residential replacement in a single day. If your project requires extensive ductwork repair, it may take a bit longer, but we will always give you a clear timeline before we start.

Can I just replace the outdoor unit? 

While technically possible, we almost always recommend replacing both the indoor and outdoor units. Modern systems are designed as matched sets. Mixing an old indoor coil with a new outdoor condenser usually results in poor efficiency and can void your warranty.

Do you offer emergency services? 

Yes. We keep our phones staffed 24/7. If your system fails in the middle of a heatwave, you can speak with a real person and get on our schedule for a prompt visit.
