Furnace Installation, Repair & Maintenance in Gulfport, MS

A properly functioning furnace is essential for comfort during Gulfport’s colder months. Horton Heating, Air & Electrical, LLC offers complete furnace services for residential and light commercial properties in Gulfport, MS. From new installations to emergency repairs and ongoing maintenance, our team ensures safe, efficient, and code-compliant heating solutions tailored to your property’s specific needs.


Professional Furnace Installation for Homes and Businesses

Installing a furnace requires careful planning and technical expertise. We begin each installation by assessing your building’s heating load, insulation levels, duct configuration, and fuel availability. Our technicians recommend the most suitable furnace type—gas, electric, or dual-fuel—based on these factors and your budget.


Once a model is selected, we install the furnace and ensure proper connection to your ductwork, electrical supply, and ventilation system. For new constructions or full system upgrades, we also install thermostats and safety controls to support modern operation. Every installation includes performance testing to confirm proper airflow, ignition, and heat output.

Furnace Replacement for Aging Systems

If your current furnace is more than 15 years old or experiencing repeated issues, replacement may be more cost-effective than ongoing repairs. We evaluate system efficiency, operating costs, and component condition to determine if replacement is warranted.


Our team removes the old furnace, inspects supporting infrastructure, and installs a new, high-efficiency unit that meets modern performance standards. Furnace replacement is often paired with upgrades to ductwork, thermostats, or filtration systems to improve indoor comfort and energy savings.

Furnace Repair Services with Same-Day Availability

When your furnace breaks down during a cold front, prompt repair is critical. We provide reliable furnace repair services across Gulfport to restore heat quickly and safely. Common issues include ignition failure, blower motor malfunctions, clogged filters, and faulty limit switches.


Our technicians arrive with the tools and diagnostic equipment needed to assess your system, identify the root cause, and complete the necessary repairs. Most issues can be resolved on-site during the first visit, minimizing disruption to your home or business.

Electric and Gas Furnace Diagnostics

Different furnace types require specialized service. Whether you have a gas-fired unit or an electric model, we follow manufacturer-approved diagnostic procedures to evaluate your equipment. This includes testing control boards, heating elements or burners, safety switches, and airflow sensors.


Gas furnaces receive additional inspection of combustion chambers, pilot lights, and flue systems to ensure safe venting and proper fuel burn. Electric furnaces are checked for relay function, resistance levels, and thermostat signal integrity.

Preventive Furnace Maintenance for Seasonal Reliability

Routine furnace maintenance extends system life, improves efficiency, and reduces the risk of breakdowns. We offer seasonal furnace tune-ups that include inspecting electrical connections, cleaning internal components, and checking heat exchanger condition.


Our maintenance services also involve testing gas pressure or voltage levels, inspecting air filters, and verifying proper operation of thermostats and safety controls. We recommend scheduling maintenance in early fall to prepare your system for the cooler months ahead.

Heat Exchanger Inspection and Safety Checks

A cracked or damaged heat exchanger can lead to serious safety risks, including carbon monoxide leaks. During maintenance or diagnostic visits, we visually and mechanically inspect the heat exchanger for cracks, corrosion, or leaks.


We also test for carbon monoxide and verify that flue gas is properly vented outside the building. These safety checks are essential for gas furnace systems, especially those operating beyond their expected service life.

Blower Motor and Airflow Calibration

Proper airflow is critical for efficient furnace performance and even heat distribution. We inspect and service blower motors, belts, and control boards to ensure that your system delivers the correct volume of air through your ductwork.


If airflow imbalances are detected, we may adjust fan speed, clean motor assemblies, or recommend minor duct modifications. Consistent airflow supports better temperature regulation and extends the life of your equipment.

Thermostat Compatibility and Upgrades

A new or recently repaired furnace may benefit from an upgraded thermostat to improve performance. We ensure that your thermostat is properly calibrated and compatible with your system’s staging and fan control logic.


For customers interested in enhanced scheduling or energy savings, we install smart thermostats and program them to support your heating preferences. These upgrades are especially effective when paired with variable-speed furnaces or multi-zone configurations.

Furnace Services for Light Commercial Properties

In addition to residential work, we provide furnace installation and service for small commercial facilities such as office buildings, retail shops, and service businesses. We evaluate heating needs based on floor area, occupancy, and structural characteristics to recommend appropriate solutions.


Commercial services include rooftop unit installation, furnace repair, and seasonal maintenance to maintain comfort and minimize downtime for staff and customers.

Code Compliance and Local Permit Requirements

Every furnace installation and major repair is performed in full compliance with Gulfport mechanical codes and applicable state regulations. We pull permits where required and schedule inspections for verification of gas line integrity, venting, and electrical connections.


All work is documented for warranty validation, insurance purposes, and future system servicing.
