HVAC Services in Gulfport, MS

At Horton Heating, Air & Electrical, LLC, we specialize in comprehensive HVAC services for both residential and light commercial clients in Gulfport, MS. Whether you're constructing a new home, upgrading an aging system, or managing climate control for a business, our technicians handle every aspect of heating, ventilation, and air conditioning systems with precision and compliance.


New HVAC Installation for Homes and Businesses

New HVAC installation requires careful planning and technical expertise. We assess the square footage, layout, and ventilation needs of your property to determine the right unit size and efficiency level. For residential clients, we ensure that indoor comfort is optimized year-round through properly sized systems. For light commercial applications, we support various facility types, including offices, retail spaces, and small warehouses, ensuring adequate heating and cooling coverage in every room.


Our team installs high-efficiency HVAC units, including traditional split systems, heat pumps, and packaged rooftop units when applicable. From initial consultation through post-install inspection, we adhere to current building codes and manufacturer guidelines, ensuring energy-efficient and code-compliant installation.

HVAC Replacement and Upgrade Solutions

When HVAC systems begin to decline in performance or efficiency, replacement becomes necessary. We provide full system replacement services for homes and small businesses experiencing issues such as rising energy bills, inconsistent temperatures, or repeated repair needs.


Our process includes a thorough evaluation of the current system, followed by the removal and replacement with a modern, energy-efficient unit. We also upgrade thermostats and controls where needed to improve operational accuracy and long-term savings. Customers often choose replacement over repair when faced with obsolete equipment, refrigerant phase-outs, or frequent system failure.

Professional Ductwork Installation and Modifications

Efficient airflow begins with proper ductwork design. Horton Heating, Air & Electrical, LLC installs and modifies duct systems in new and existing buildings to support improved airflow and system efficiency. Whether you’re building a new structure or remodeling an older property, we fabricate and install ducts to match HVAC unit specifications, ceiling heights, and insulation values.


When needed, we reroute or resize existing ductwork to correct air delivery issues and support zoning controls. All duct materials used meet the mechanical code requirements of Gulfport, MS and are tested for air leaks and proper airflow before commissioning.

Duct Cleaning and Indoor Air Optimization

Dust, debris, and microbial contaminants accumulate in duct systems over time, degrading indoor air quality and restricting airflow. Our duct cleaning services help eliminate buildup within your HVAC system using industry-standard vacuums and agitation tools.


We provide this service as part of scheduled maintenance or as a standalone request for customers experiencing excessive dust, mold growth, or allergy symptoms indoors. Every duct cleaning includes inspection of registers, returns, and air handler compartments to verify system hygiene and performance.

AC Installation and Seasonal Startups

Our AC installation services cover central air conditioners, ductless mini-splits, and hybrid systems. We install air conditioning units rated for Gulfport’s humidity levels and verify cooling performance under real operating conditions.


During seasonal startup or replacement, we assess refrigerant charge, airflow, and thermostat operation to ensure optimal performance. AC installation projects often coincide with upgrades to zoning systems or ductwork modifications for improved cooling balance.

Heat Pump Installation and Repair Services

Heat pumps provide both heating and cooling from a single system and are increasingly popular throughout Gulfport for their energy efficiency. We install air-source and mini-split heat pumps for homes and light commercial properties, ensuring compatibility with existing ductwork or recommending ductless options when necessary.



In addition to new installs, we troubleshoot and repair heat pump issues including reversing valve failures, compressor problems, and defrost cycle malfunctions. Whether your heat pump is underperforming or needs full replacement, we offer tailored solutions backed by diagnostics.

Thermostat Installation and Smart Controls

Accurate temperature control depends on a reliable thermostat. We install programmable, non-programmable, and smart thermostats to fit your HVAC system and comfort goals. If your current thermostat is outdated or malfunctioning, we can upgrade it to a more precise and energy-efficient model.


Smart thermostats allow for scheduling, remote access, and automated settings—all supported by our installation and setup services. Proper thermostat calibration also supports HVAC longevity and more balanced comfort across zones.

Scheduled HVAC Tune Ups and System Checks

Routine HVAC tune-ups extend equipment life and reduce the risk of breakdowns. Our maintenance includes inspection of electrical connections, refrigerant levels, blower operation, and heat exchanger condition. We also verify airflow, lubricate moving parts, and clean key components as needed.


For Gulfport clients, we recommend seasonal maintenance before peak heating and cooling periods. This service is especially beneficial in preventing mid-summer failures or winter inefficiencies for both residential and light commercial systems.

Coil Cleaning Services for Peak Efficiency

Condenser and evaporator coils accumulate dirt over time, reducing cooling performance and increasing system strain. Our coil cleaning service helps restore efficiency by removing dirt, debris, and buildup from internal and external coil surfaces.


We utilize safe, manufacturer-approved chemicals and water pressure techniques to clean coils without damaging fins or causing corrosion. Coil maintenance is often included in scheduled service agreements or can be requested as a standalone HVAC cleaning solution.

Furnace Repair and Maintenance

In cooler months, an underperforming or malfunctioning furnace can cause serious indoor discomfort. We repair both gas and electric furnaces in homes and small businesses throughout Gulfport. Our service includes diagnosing ignition problems, blower motor failures, and thermostat inconsistencies.


We also maintain heating systems through seasonal inspections, verifying combustion safety, burner alignment, and airflow performance. Furnace service calls include safety checks and full system documentation for warranty or compliance purposes.

Emergency HVAC Repair Services Available 24/7


HVAC failures often happen outside business hours. We offer emergency HVAC repair services for urgent issues such as system shutdowns, no heat or cooling, refrigerant leaks, or electrical failures.
