Call for Emergency Services | We offer financing

When Annapolis businesses need dependable commercial HVAC installation and service, they call Big Time Comfort. We design, install, repair, and maintain high‑performance commercial heating and cooling systems for offices, retail centers, medical facilities, warehouses, apartment complexes, restaurants, schools, government buildings, and industrial facilities across Anne Arundel County and surrounding communities.
Your building’s comfort system isn’t optional — it’s operational infrastructure. Downtime disrupts business. Poor design increases energy costs. Inconsistent temperatures affect employees, customers, and equipment. That’s why every commercial HVAC system we deliver is engineered for reliability, efficiency, and long‑term performance.
Big Time Comfort provides complete commercial HVAC solutions, including rooftop units, packaged systems, split systems, boilers, heat pumps, VRF/VRV systems, make‑up air units, commercial ventilation, humidity control, and advanced indoor air quality management. Whether you need emergency repair, full system replacement, new construction HVAC design, or preventative maintenance for multi‑building properties, we deliver systems built to support continuous operation and predictable energy costs.
Every project is handled by a Maryland‑licensed Master HVAC Technician with 15 years of commercial experience — ensuring your building receives engineered solutions, precise load calculations, proper airflow design, and equipment installed to manufacturer specifications. We help businesses reduce downtime, extend equipment lifespan, stabilize indoor temperatures, and maintain safe, comfortable environments year‑round.
From small storefronts to large commercial campuses, Big Time Comfort keeps your heating and cooling systems running efficiently, safely, and without interruption — so your business can operate at full strength.
