Air Conditioning & AC Repair

Why is my AC running but blowing warm air?
Start by checking that the thermostat is set to cooling and that the filter isn’t heavily clogged. If the air is still warm, the issue could involve airflow, the outdoor unit, electrical components, or the refrigerant circuit. A technician can test the system to determine the cause. Learn more about AC repair in Madison.
What should I do if I see ice on my air conditioner?
Turn cooling off and let the ice thaw. Don’t chip it off. A dirty filter or restricted airflow can contribute to freezing, but recurring ice can also point to another problem that needs diagnosis. If it freezes again or still won’t cool after thawing, request service.
Why does my air conditioner keep turning on and off?
Frequent short cycles can come from airflow restrictions, thermostat problems, or equipment that shuts down before completing a normal cycle. If it happens repeatedly or the home isn’t reaching the set temperature, note how long the system runs before it shuts off. That gives the technician a useful starting point.
Can you repair my AC if another company installed it?
Yes. Gatlin’s services all makes and models, including systems installed by other contractors. If you have the brand and model number handy, include them when you schedule. Parts availability and warranty coverage can vary by equipment.

Heating, Furnaces & Heat Pumps

Why is my furnace running but the house isn’t warming up?
The blower can move air even when the furnace isn’t producing heat. Check the thermostat setting and filter first. If the air stays cool or the furnace starts and stops repeatedly, a technician can check ignition, airflow, and system controls. See our Madison heating repair services.
Is frost on my outdoor heat pump normal?
A light coating of frost can be normal during heating. A heat pump periodically runs a defrost cycle to clear it. Thick ice that remains on the unit, or ice paired with poor indoor heating, is a reason to have the system checked.
Why does my thermostat say AUX HEAT?
On a heat pump system, auxiliary heat is backup heat. It can come on during colder weather, during defrost, or when the thermostat calls for a large temperature increase. If it runs frequently in mild weather or the home still won’t warm up, ask for a heat pump evaluation.

HVAC Installation & Replacement

Should I repair or replace my heating and cooling system?
Start with the diagnosis. A repair may make sense when the problem is isolated and the rest of the equipment is in good condition. Replacement is worth comparing when breakdowns repeat, a major repair is expensive, or the system no longer keeps your home comfortable. Age matters alongside condition, repair history, and cost. See HVAC installation and replacement in Madison.
How do you determine the right HVAC size for my home?
Square footage is one factor. Insulation, windows, ceiling height, sun exposure, and existing ductwork also affect what your home needs. If your old system cycled frequently or left rooms uncomfortable, bring that up during the estimate so those problems can be considered before equipment is selected.
Can I replace just the outdoor AC or heat pump unit?
Sometimes. The new outdoor unit must be compatible with the indoor coil or air handler, refrigerant, and controls. The condition of the indoor equipment also matters. Have both components evaluated before deciding whether a partial replacement makes sense.
Is a ductless mini-split a good option for one room?
A ductless mini-split can be a good fit for an addition, finished bonus room, or other space that lacks suitable ductwork. The right setup depends on the room’s heating and cooling needs, where the units can go, and how the electrical and drain connections can be routed.

HVAC Maintenance & Tune-Ups

When should I schedule HVAC maintenance in North Alabama?
Spring is a good time to check cooling before summer, and fall is a good time to check heating before colder weather. If your heat pump runs in both seasons, ask what service schedule makes sense for your equipment and how you use it. See seasonal HVAC maintenance in Madison.
What happens during an HVAC tune-up?
The work depends on the equipment and the season. A visit can include checking the filter and airflow, inspecting electrical connections, checking the drain on cooling equipment, and testing operation. If the technician finds a problem, ask which work is included in the tune-up and which work would be a separate repair.
Do you offer HVAC maintenance plans?
Yes. Gatlin’s offers HVAC maintenance plans for scheduled system care. Ask about current plan options, which equipment is covered, and what’s included for your property.
How often should I check my HVAC filter?
Check it monthly at first to see how quickly it loads up. Follow the replacement guidance for your system and filter type. Pets, remodeling dust, and heavy system use can mean you need to check it more often. If you’re changing filter types, ask whether your system can handle the added airflow resistance.

Ductwork, Airflow & Indoor Air Quality

Why are some rooms hotter or colder than others?
Uneven temperatures can come from duct leaks, restricted airflow, limited return air, insulation differences, or afternoon sun. Note which rooms are affected and when it happens. A ductwork and airflow evaluation can help determine whether the issue starts with air distribution or elsewhere in the home.
Why does my home feel humid even when the AC is running?
An AC can reach the thermostat setting while leaving the home feeling damp. Short run times, equipment sizing, airflow, and moisture entering the home can all contribute. Before buying a dehumidifier or replacing equipment, find out whether the problem is with the system or another source of moisture.
Can I improve indoor air quality through my HVAC system?
Depending on the concern, filtration, humidity control, and ventilation may help. Start with what you notice most: excess dust, damp air, stale rooms, or uneven airflow. That helps narrow down which indoor air quality options fit your home and system.

Estimates, Repair Costs & Financing

How much does AC or heating repair cost?
The cost depends on the cause, the equipment, and the parts and labor needed. Two systems with the same symptom can need different repairs. When scheduling, ask about the diagnostic charge. Once the problem is identified, ask what the proposed repair includes before deciding how to proceed.
How do I get an estimate for a new HVAC system?
Request a replacement estimate and tell us what you’d like to improve, whether that’s reliability, noise, uneven temperatures, or something else. Reviewing the existing system and your priorities helps narrow the options and clarify what the installation would involve.
Do you offer financing for HVAC replacement or repairs?
Financing is available for qualifying homeowners and projects, subject to lender approval. Some repairs may qualify, depending on the program and project amount. See our HVAC financing options for current programs and review the lender’s terms before applying.
What warranty comes with a new heating and cooling system?
Coverage varies by equipment and proposal. Ask which parts are covered, whether labor is included, whether registration is required, and whom to contact if service is needed. Review those details in writing when comparing systems.

Yes. Gatlin’s provides commercial HVAC repair, installation, and maintenance in Madison, Athens, and nearby areas. When you call, share the property type, the equipment involved if known, and whether the issue affects one zone or the entire building.
