From emergency AC repairs to complete system installations, TGA Services delivers reliable heating, cooling, and ventilation solutions for commercial properties. Whether you need a new high-efficiency system, routine maintenance, or urgent repairs, our licensed HVAC technicians keep your property comfortable year-round.
HVAC systems are the backbone of indoor comfort and air quality, but not every provider offers the same level of expertise or reliability. Here's who benefits most from working with TGA Services for heating, cooling, and ventilation.
You oversee multiple commercial properties and need an HVAC partner who shows up on schedule, handles maintenance agreements across your portfolio, and responds quickly when a tenant's system goes down. Consistency and communication matter as much as technical skill.
Your office building, warehouse, or mixed-use property requires HVAC systems that perform efficiently at scale. You need a contractor experienced with commercial-grade equipment (rooftop units, VRF systems, building automation controls) who understands the impact HVAC downtime has on tenants and operations.
Your business depends on proper airflow, kitchen exhaust systems, or climate control that keeps customers comfortable and meets health code requirements. You need an HVAC contractor who understands the unique ventilation demands of food service and retail environments.
You're a general contractor or renovation company that needs a reliable HVAC sub for commercial projects. You want a team that coordinates with your schedule, communicates proactively, and delivers work that passes inspection the first time.
Not Sure What HVAC Service You Need? That's what our initial assessment is for. We'll evaluate your current system, diagnose any issues, and recommend the most cost-effective path forward: whether that's a simple repair, a maintenance plan, or a full system upgrade.

As a general rule, if your system is over 15 years old and needs frequent or major repairs, replacement is usually the better investment. Other signs it's time to replace include frequent breakdowns, rising energy bills despite maintenance, inconsistent temperatures throughout your building, and the use of R-22 refrigerant which is no longer manufactured. We'll give you an honest assessment and never push replacement when a repair makes more sense.
Yes. Commercial HVAC is a core part of our business. We install, repair, and maintain commercial systems including rooftop units, VRF and mini-split systems, building automation controls, and custom ventilation solutions. We work with office buildings, retail spaces, restaurants, medical facilities, warehouses, and multi-tenant properties. Our technicians are experienced with commercial-grade equipment and understand the operational demands of business environments.
Yes. We offer preventive maintenance agreements for commercial systems. A typical plan includes two visits per year (one before cooling season and one before heating season) covering filter changes, coil cleaning, refrigerant checks, electrical inspections, and system performance testing. Maintenance plans extend equipment life, reduce emergency breakdowns, and often include priority scheduling.
Several factors affect efficiency: equipment age and SEER rating, ductwork condition, thermostat programming, and regular maintenance. Beyond equipment, sealing ductwork leaks, adding insulation, and installing a programmable or smart thermostat all contribute to lower bills. During our assessment, we identify the most impactful efficiency improvements for your specific situation.
Yes. We provide complete ductwork services including new installation, repair, sealing, insulation, and modification. Leaky or poorly designed ductwork can waste 20-30% of your conditioned air, so ductwork condition is always part of our system evaluation. Whether you need a new duct run to an addition, repairs to damaged sections, or a full ductwork replacement, we handle it.
Absolutely. We install and program smart thermostats from major manufacturers including Ecobee, Nest, Honeywell, and others. Smart thermostats learn your schedule, adjust to occupancy, and provide remote control via smartphone. We'll recommend the best option for your system and ensure it's properly integrated with your HVAC equipment.
Yes. We understand that HVAC failures don't wait for business hours, especially during a North Carolina summer or an unexpected cold snap. We offer emergency service for urgent situations like complete system failures, no heat during freezing temperatures, and refrigerant leaks. Contact us and we'll prioritize getting your system back online as quickly as possible.
Schedule your cooling system tune-up in early spring (March-April) before the summer heat arrives, and your heating system tune-up in early fall (September-October) before cold weather sets in. Scheduling early ensures you're not waiting in line during peak season when every HVAC company is booked. Our maintenance plan customers are scheduled automatically so they never miss a tune-up.
Yes, most HVAC installations and significant repairs require mechanical permits in North Carolina. This includes new system installations, equipment replacements, ductwork modifications, and gas line work. We handle all permit applications and coordinate municipal inspections as part of our standard service. Working with a licensed contractor who pulls proper permits protects you legally and ensures your system meets current building codes.
