Managing a commercial building means keeping every system running smoothly, including the one on your roof. Your HVAC unit plays a critical role in maintaining comfort, air quality, and energy efficiency across your property. At GAC Services, we provide comprehensive commercial rooftop HVAC services for businesses in Gaithersburg and throughout Maryland.
With over 50 years of experience serving local businesses, we understand the demands of commercial buildings, from retail and office spaces to industrial facilities.

Rooftop HVAC Repair
Rooftop units work hard year-round. Over time, exposure to weather, heavy usage, and mechanical wear can lead to system failures. If your building isn’t cooling or heating consistently, or your energy bills are climbing with no clear reason, it may be time for a rooftop HVAC repair.
Common issues we handle include:
- Frozen evaporator coils
- Faulty compressors or fan motors
- Refrigerant leaks
- Electrical or control system failures
- Poor airflow or inconsistent temperatures
We respond quickly to minimize downtime and protect your indoor environment. Our technicians are trained to service all major rooftop HVAC systems and carry the parts needed to complete most repairs on the spot.
Need urgent service? We also offer emergency rooftop HVAC repairs for businesses that can’t afford to wait.
Commercial Rooftop HVAC Unit Installation
If you’re constructing a new commercial building or expanding your space, a rooftop HVAC system can be a smart, space-saving solution. These systems are built for durability, ease of access, and efficient climate control, making them ideal for offices, retail locations, schools, and light industrial facilities.
When you work with GAC Services, we handle the entire rooftop HVAC installation process, including:

Commercial Rooftop Unit Replacement
Even the best HVAC systems have a lifespan. If your current rooftop unit is nearing the 15- to 20-year mark, struggling to meet demand, or constantly needing service, replacement might be the smarter move.
Signs it’s time to consider rooftop HVAC unit replacement:
- Frequent breakdowns and rising repair costs
- Significant drops in performance or airflow
- Loud operation or persistent system alarms
- Poor energy efficiency despite regular maintenance
We’ll evaluate your current system and help you compare replacement options that align with your space, energy goals, and budget. Our rooftop HVAC replacement services include removal and disposal of old equipment, ensuring everything is handled safely and according to code.
New systems offer better energy performance, lower operating costs, and modern control options that give you more flexibility in managing comfort.
