HVAC Maintenance & Tune-Ups in Gulfport, MS

Regular HVAC maintenance is the foundation of a long-lasting, efficient heating and cooling system. Horton Heating, Air & Electrical, LLC offers comprehensive seasonal tune-ups and preventive maintenance for homes and light commercial properties throughout Gulfport, MS. Our services help reduce breakdowns, improve energy efficiency, and ensure consistent comfort throughout the year.


Seasonal Tune-Ups for Heating and Cooling Systems

Seasonal tune-ups are scheduled just before peak usage periods—spring for cooling systems and fall for heating systems. This service helps identify worn components, clean critical parts, and ensure that your HVAC equipment is operating safely and efficiently.


Our technicians perform a full system inspection during each tune-up, addressing both the mechanical and electrical functions of your HVAC unit. We assess the condition of indoor and outdoor components, verify refrigerant levels, test thermostat responsiveness, and check airflow output.

Preventive Maintenance for Year-Round Reliability

Preventive maintenance is designed to extend the life of your HVAC system while minimizing the risk of unexpected failures. Unlike reactive service calls, our maintenance visits focus on catching small issues before they develop into costly problems.


We clean coils, clear condensate drains, lubricate moving parts, and test all safety controls. For heat-based systems, we inspect the heat exchanger and combustion areas. For cooling systems, we confirm proper refrigerant pressure and fan operation. These services are performed using detailed checklists and diagnostic equipment.

HVAC Inspections for System Performance and Safety

System inspections go beyond general maintenance by evaluating performance data, operational accuracy, and safety. We check voltage and amperage readings, confirm system cycles, and ensure that air pressure and duct connections meet performance standards.


For homes and businesses in Gulfport, inspections are especially important before peak summer and winter months. They help verify that systems are not overworking due to humidity, restricted airflow, or component degradation.

Maintenance for Heat Pumps and Ductless Systems

Heat pumps and ductless mini-split systems require unique maintenance procedures. Our team performs seasonal service on these systems, inspecting reversing valves, checking refrigerant levels, and confirming defrost cycle functionality.


For ductless systems, we clean indoor air handlers, clear filters, inspect remote sensors, and test communication between units. Preventive service for these systems ensures that both heating and cooling functions are fully operational when needed.

Filter Inspection and Replacement Services

Dirty filters restrict airflow, reduce efficiency, and contribute to indoor air quality issues. As part of every maintenance visit, we inspect and replace filters if necessary. We also advise on proper filter selection and replacement frequency based on system type, household occupancy, and allergy concerns.


Filter maintenance is especially important in Gulfport’s humid environment, where mold and airborne particulates can accumulate quickly and affect HVAC performance.

Coil Cleaning for Optimal Efficiency

Coils in your HVAC system transfer heat and help regulate indoor temperatures. Over time, they collect dirt and debris, leading to reduced efficiency and increased strain on your system. We clean evaporator and condenser coils using manufacturer-approved techniques and solutions to restore full heat transfer capability.


Coil cleaning is a key component of seasonal maintenance, especially before the start of summer cooling or winter heating cycles.

Condensate Drain and Blower Motor Checks

Blocked condensate drains can cause water leaks and lead to mold growth. Our tune-ups include cleaning and flushing drain lines to ensure proper drainage. We also inspect blower motors for dirt accumulation, electrical issues, and proper speed settings to support even airflow throughout the system.


These checks are essential for avoiding mid-season malfunctions and preserving indoor air quality.

Electrical Testing and System Calibration

HVAC systems rely on multiple electrical components that must function in coordination. During tune-ups, we inspect wiring connections, test capacitors, verify voltage readings, and confirm that control boards are responding correctly.


System calibration includes adjusting thermostat settings, verifying communication with air handlers or condensers, and confirming staging sequences for multi-speed or variable systems.

Maintenance Plans for Gulfport Customers

We offer maintenance plans that include scheduled seasonal tune-ups, priority service, and discounts on repairs or replacement parts. These plans are ideal for homeowners and business owners who want to keep their systems in peak condition without the hassle of scheduling last-minute visits.


Plan holders receive reminders and preferred appointment times during high-demand seasons, ensuring uninterrupted comfort year-round.

Light Commercial HVAC Maintenance Programs

For light commercial properties such as small offices, retail spaces, and service buildings, we provide customized maintenance programs that minimize downtime and maintain operational continuity. We inspect rooftop units, thermostats, ductwork, and zoning components as part of routine commercial service.


Maintenance for commercial systems is often scheduled quarterly or semi-annually, depending on usage patterns and occupancy levels.
