When your air conditioner starts struggling during a hot Dothan summer, most homeowners only notice one thing: the house is not cooling properly. What many people do not realize is that the type of refrigerant metering device inside the HVAC system plays a major role in comfort, efficiency, humidity control, and repair costs. Two of the most common metering devices found in residential HVAC systems are the TXV (Thermostatic Expansion Valve) and the fixed orifice, sometimes ca

Airflow problems are one of the most common reasons homeowners in Dothan and surrounding Wiregrass communities deal with hot rooms, weak airflow, high energy bills, and HVAC systems that never seem to keep up. Many people assume they need a new air conditioner or heater when the real issue is poor airflow balancing inside the home. If certain rooms stay warmer in the summer or colder in the winter, airflow balancing may be the solution. Understanding the basics of grilles, da

If you’ve ever noticed water around your indoor HVAC unit or a sudden shutdown during peak cooling season, there’s a good chance condensate management is involved. It’s not the most talked-about part of your system, but in the humid climate of Dothan, AL and the surrounding Wiregrass area, it’s one of the most important. Let’s break it down in a simple, homeowner-friendly way so you know what’s going on—and how to avoid expensive damage. Why Condensate Management Matters in t

If your air conditioner isn’t cooling like it should, there’s a good chance a refrigerant leak could be the problem. In the hot, humid climate of Dothan, Alabama and the Wiregrass area, your HVAC system works hard almost year-round.

Why It Matters for Your HVAC System in Dothan and the Wiregrass When it comes to installing or repairing an HVAC system, most homeowners never see what happens behind the scenes. They notice when the air is cold, the home is comfortable, and the system is working properly. But one of the most important parts of any AC installation or major repair happens before the system is even charged and started. That step is pulling a proper vacuum and removing moisture from the system.

When most homeowners in the Wiregrass think about HVAC installation or repair, they usually focus on the big things—air conditioners, heat pumps, thermostats, and ductwork. But some of the most important work happens in the small details that you never see. One of those details is brazing copper refrigerant lines, and more specifically, brazing with a nitrogen purge. At Eco Heating and Cooling, we take pride in doing HVAC work the right way. For homeowners in Dothan and surro

When your air conditioner isn’t cooling like it should during a hot Alabama summer, the problem often comes down to refrigerant charge. Too much or too little refrigerant can dramatically reduce efficiency, increase energy bills, and cause serious damage to your HVAC system.

This process ensures your system runs efficiently, cools your

When spring starts warming up in Dothan, Alabama, the phones start ringing. Homeowners in Enterprise, Ozark, Headland, Daleville, Midland City, Newton, and Cottonwood all begin switching their thermostats from heat to cool.

If you live in Dothan, Alabama or surrounding Wiregrass communities like Enterprise, Ozark, Headland, Daleville, Slocomb, Abbeville, Kinsey, Taylor, or Wicksburg, you already know one thing for sure: humidity is a constant battle.

If you live in Dothan, Enterprise, Ozark, Headland, Daleville, Ashford, Cottonwood, or anywhere in the Wiregrass, your HVAC system works hard almost year-round. Between humid Alabama summers and chilly winter mornings, your air conditioner and furnace depend on one key component to keep air moving through your home: the blower wheel. At Eco Heating and Cooling, we see it all the time on HVAC service calls across Dothan and surrounding areas — homeowners dealing with weak airf

If your home in Dothan or the surrounding Wiregrass area is heated by an electric furnace, two small components do a lot of heavy lifting behind the scenes: sequencers and relays. When one of them fails, it can lead to no heat, weak heat, tripped breakers, or sky-high electric bills—especially during cold snaps we see in South Alabama. At Eco Heating and Cooling, we frequently diagnose winter heating issues across Enterprise, Ozark, Headland, and the greater Wiregrass that co

When winter temperatures drop across the Wiregrass, homeowners depend on their heating systems to work safely, efficiently, and consistently. If your furnace or heat pump seems to run constantly, heats unevenly, or shuts off unexpectedly, the issue may not be the thermostat or the unit itself—it could be static pressure . Static pressure is one of the most important but least understood measurements in residential HVAC systems. At Eco Heating & Cooling, we regularly diagnose

However, in many homes across Dothan, Enterprise, Ozark, Headland, Daleville, Rehobeth, Midland City, and nearby South Alabama communities, the real issue is hidden out of sight: leaking air ducts. Leaking ductwork is one of the most common causes of high energy bills, uneven temperatures, excess dust, and ongoing comfort problems. At Eco Heating & Cooling, we regularly find t

Understanding how the defrost cycle works—and when it may indicate a problem—can help you avoid comfort issues,

But while you’re busy decking the halls and baking holiday treats, there’s one important thing you might be forgetting to check: your furnace.
