Heating Systems We Install

The right system depends on your home, your existing setup, and how you want it to perform through both winter and summer. We install several heating options across North Alabama and help homeowners choose based on comfort, efficiency, fuel availability, and the condition of the current system. 

 

Gas Furnaces

Gas furnaces are a common choice for homes with natural gas service and provide strong, steady heat when temperatures drop. Efficiency is measured by AFUE, which shows how much of the fuel is converted into usable heat. Our team is also Natural Gas Piping Certified, which matters when installation involves gas connections or piping work. 

Heat Pumps

Heat pumps provide both heating and cooling from one system. In winter, they move heat into the home, then reverse the process in summer to cool it. For many North Alabama homes, especially those already using electric HVAC equipment, they can be a practical year-round option. 

Dual-Fuel Systems

A dual-fuel system combines an electric heat pump with a gas furnace. The heat pump handles much of the heating during milder weather, while the furnace can take over when more heat is needed. It can be a good fit for homes with natural gas that want the flexibility of both systems. 

Complete HVAC System Replacement

If both your heating and cooling equipment are older or no longer working well together, replacing them at the same time may make more sense. A matched system helps the indoor and outdoor equipment operate as intended and gives you one clear setup for year-round comfort. 

Ready for North Alabama Winters

North Alabama winters may be shorter, but cold snaps across the Tennessee Valley and the Shoals can still push an aging system hard. We install heating systems with the home’s actual heating needs in mind, not just the size of the equipment being replaced. 

Every installation starts with proper system sizing, followed by careful installation and testing. We also walk you through the thermostat and controls before we leave, so you know how to use the new system from day one. Financing is available on qualifying installations, and free replacement estimates make it easier to compare your options before deciding.

Repair or Replace Your Heating System?

A heating problem does not always mean you need a new system. If the equipment is still in good condition and the repair is reasonable, fixing it may be the better choice.  

Replacement starts to make more sense when repairs are becoming frequent or expensive, the system struggles to hold a comfortable temperature, some rooms stay colder than others, heating cycles run too long or too often, or an older system is facing a major component failure.  

Rising operating costs can be another sign that the system is working harder than it should. Alabama Climate Control can inspect your current setup, explain what is going on, and help you compare heating repair with replacement before you decide. 

Furnace or Heat Pump: Which Is Right for Your Home?

Both can work well in North Alabama, but the better fit depends on how your home is set up. A gas furnace uses natural gas and is often a good choice for homes that already have gas service and prefer stronger heat during colder weather.  

A heat pump runs on electricity and handles both heating and cooling in one system. We look at your utilities, current equipment, comfort priorities, and budget before recommending one over the other.

5 Stars ⭐⭐⭐⭐⭐
​Alabama Climate Control truly prides themselves on quality customer service. As a customer who was overly frustrated because my AC went out at the most hotest time of the season; they immediately understood my needs and concerns. They treated me with the utmost respect, genuine concern, and care.
​Not to mention, I contacted their after-hours department, and before I could even leave a message, someone was already returning my call—that’s award-winning customer service if you ask me! The original HVAC tech who answered assured me he’d have the office contact me first thing in the morning, and they proved they are a company of their word when I received that phone call right on schedule as promised.
​I was greeted with a prompt call from Ms. Nori—again, customer service above reproach—followed by the technician, Jeremy, who called prior to arriving and communicated every single step of the way. Jeremy went above and beyond, which clearly shows how passionate he is about his profession.
​If you’re searching for a reputable company, look no further. Alabama Climate Control treats you like more than just a customer—they treat you like family! 😉

Why Proper Heating System Sizing Matters

Replacing an old system with another unit of the same size is not always the right move. We look at the home itself, including its size, layout, insulation, windows, ductwork, airflow, and local weather conditions, before recommending equipment.  

A system that is too large can turn on and off too often, while one that is too small may struggle to keep the house comfortable when temperatures drop. Proper sizing helps the new system run more consistently and do the job it was installed to do.

What to Expect During Heating Installation

A new heating system is a bigger job than swapping out a piece of equipment, so we keep the process clear from the start. You will know what we are checking, what is being installed, and what to expect before the work begins. 

 

Home Evaluation and Estimate

We start by looking at your current system, how your home heats, and what may be affecting comfort. From there, we can explain your options and provide a replacement estimate based on the actual work needed. 

System Sizing and Equipment Selection

The new system is selected around your home, not just the size of the old unit. We consider the heating load, existing setup, fuel source, efficiency options, and how the equipment needs to work with the rest of your HVAC system. 

Removal of Existing Equipment

Once the plan is approved, the old equipment is disconnected and removed carefully so the space is ready for the new system. 

New System Installation

Our team installs the new furnace, heat pump, or complete HVAC system and completes the connections required for that setup, including ductwork, electrical, gas, refrigerant, venting, and controls where applicable. 

Startup and Performance Testing

Before we consider the job finished, we start the system and check that it is operating properly. That includes airflow, thermostat response, heating performance, and the safety controls tied to the equipment. 

Homeowner Walkthrough

We show you how the new system works, go over the thermostat setup, and explain the basics you need to know for everyday use. You should feel comfortable operating the system before we leave.

Frequently Asked Questions

Both are good options for North Alabama. Gas furnaces provide stronger heat and tend to perform well during colder weather, while heat pumps are efficient in mild to moderate cold and also provide cooling in summer. Some homeowners choose a dual-fuel system, which pairs a heat pump with a gas furnace backup. 

AFUE measures how efficiently a furnace converts fuel into heat. An 80% AFUE furnace turns 80% of the fuel it uses into usable heat, while high-efficiency condensing models can reach 95% to 98% AFUE. In North Alabama, an 80% AFUE furnace can be a cost-effective choice, while higher-efficiency models may make more sense for homes where the furnace runs more often during winter. 

Yes, in many cases. The project may involve adding a gas line if one is not already available, installing the furnace and flue venting, and connecting the new equipment to the existing ductwork. Our team can review the current setup during a free estimate and explain what the conversion would require. 

An oversized system often short-cycles, meaning it heats the home quickly, shuts off, then turns back on again before temperatures fully stabilize. Other signs can include temperature swings, frequent on-and-off cycling, and rooms that feel unevenly heated. A Manual J load calculation can help confirm whether the system is properly sized. 

Many modern heating systems, including current Trane models, can work with smart thermostats such as the Trane XL824, Nest, and Ecobee. Smart thermostats can offer scheduling, remote access, and energy-use tracking. We can install a compatible thermostat with your new system and walk you through the setup. 

Professional installation helps make sure the system is properly sized, vented, wired, and installed according to applicable codes. Improper installation can create safety concerns, including carbon monoxide risks from incorrectly vented gas furnaces or electrical problems from faulty wiring. Our licensed technicians test the system and its safety controls before the job is completed.
