Prevent costly breakdowns and extend equipment life with a customized maintenance program. Our commercial maintenance agreements are designed to fit your specific equipment and business needs.
Commercial HVAC systems should be professionally serviced at least twice per year — once before cooling season (spring) and once before heating season (fall). However, systems with heavy usage such as restaurants, retail stores, and medical facilities often benefit from quarterly maintenance. High-traffic buildings or those with 24/7 operations may need monthly filter changes and more frequent inspections. Regular maintenance prevents costly breakdowns, extends equipment life, and keeps energy bills in check.
We service all types of commercial properties throughout Dallas-Fort Worth, including office buildings, retail stores, shopping centers, restaurants, warehouses, distribution centers, medical and dental offices, veterinary clinics, churches, schools, daycares, gyms, salons, auto dealerships, and multi-family properties (apartments, condos).

Commercial HVAC systems typically last 15-20 years with proper maintenance. Rooftop units (RTUs) average 15-20 years, while chillers may last 20-25 years. However, systems that run continuously, operate in harsh conditions, or don't receive regular maintenance may need replacement sooner — sometimes as early as 10-12 years. Signs it's time to replace include frequent repairs, rising energy bills, inconsistent temperatures, and R-22 refrigerant (which is being phased out). Regular maintenance is the best way to maximize your equipment's lifespan.
