What types of commercial HVAC systems do you work on?

Our technicians are trained to work on brands like Trane, Carrier, Daikin, York, Lennox, Amana, Goodman, Rheem, and others.
How quickly can you respond if my business has an HVAC emergency?
We prioritize commercial clients experiencing system failures, extreme temperature issues, or health/safety concerns. In most cases, we can dispatch a technician the same day or within 24 hours. We understand that HVAC downtime affects employees, customers, inventory, and overall business operations.
Do you offer commercial HVAC maintenance plans?
Yes. We provide customized maintenance programs for businesses with one or multiple HVAC units. Plans typically include seasonal tune-ups, filter management, coil cleaning, refrigerant testing, airflow and static pressure checks, electrical inspections, and preventive system evaluations to reduce downtime and prevent costly repairs.
How do I know whether my commercial HVAC system needs repair or replacement?
Frequent breakdowns, rising energy bills, uneven temperatures, loud operation, equipment over 12–15 years old, poor airflow, or repeated refrigerant issues may indicate that replacement is more economical than continued repairs. We provide a full diagnostic and present clear options based on performance, cost, lifespan, and energy efficiency.
Can you replace rooftop units (RTUs) for large commercial buildings?
Yes. We provide full RTU replacement services, including system sizing, crane coordination, curb adapters, electrical and control integration, and full commissioning. Whether you have a single rooftop unit or a multi-zone system, we ensure a safe, efficient replacement with minimal disruption to your business.
Do you offer indoor air quality solutions for commercial buildings?
Absolutely. We install commercial dehumidifiers, fresh air systems, energy recovery ventilators (ERVs), advanced filtration systems, UV germicidal lights, odor reduction solutions, and ventilation improvements. These upgrades help improve comfort, productivity, and air quality for employees and customers.
How often should commercial HVAC systems be serviced?
Most commercial systems should be maintained at least twice per year — once before cooling season and once before heating season. High-load environments (restaurants, manufacturing, churches, data rooms, gyms) may require more frequent maintenance. Regular service reduces energy costs, prevents downtime, and extends equipment lifespan.
Can you help reduce my business’s heating and cooling costs?
Yes. We offer energy-efficiency solutions such as programmable thermostats, zoning systems, high-efficiency equipment upgrades, ductwork improvements, economizer repairs, ventilation balancing, and ongoing maintenance. Many businesses see noticeable reductions in monthly energy bills after upgrading HVAC controls or equipment.
Do you provide estimates for commercial HVAC installations or large repairs?
Yes. Valley Services offers clear, upfront estimates for commercial HVAC replacement, retrofits, multi-unit upgrades, RTU installations, and major repairs. We evaluate your building’s size, usage, airflow needs, and long-term operating costs to provide the most effective and cost-efficient solutions for your business.
