Commercial HVAC systems keep businesses comfortable, efficient, and operational throughout Whatcom County, Skagit County, and Snohomish County. This FAQ answers common questions about commercial HVAC service, rooftop units, preventive maintenance agreements, refrigeration, commercial plumbing, system repairs, and when to call LSM’s commercial service team.
Yes. LSM Heating Plumbing Electric services and installs commercial HVAC systems for businesses throughout Whatcom County, including Bellingham, Ferndale, Lynden, Blaine, and surrounding communities. Our commercial team also serves businesses in parts of Skagit and Snohomish counties.
LSM works on many types of commercial HVAC equipment, including rooftop units, split systems, heat pumps, ventilation systems, ductwork, commercial controls, packaged units, and comfort systems for offices, restaurants, retail spaces, warehouses, multi-family properties, and light industrial facilities.
A commercial HVAC preventive maintenance contract is a scheduled service agreement that keeps your heating, cooling, and ventilation equipment inspected, cleaned, and maintained throughout the year. These agreements help reduce emergency breakdowns, extend equipment life, improve efficiency, and give business owners better control over maintenance planning.
Most businesses benefit from a commercial HVAC maintenance agreement, especially if downtime would affect customers, employees, tenants, inventory, or operations. Regular maintenance is especially important for restaurants, retail spaces, offices, warehouses, manufacturing facilities, medical spaces, and properties with rooftop units or refrigeration equipment.
Commercial HVAC equipment should usually be serviced at least twice a year, though some systems need quarterly maintenance depending on use, building type, operating hours, and equipment condition. High-use systems, rooftop units, refrigeration equipment, and restaurant systems may need more frequent service to stay reliable.
Commercial HVAC maintenance may include inspecting and replacing filters, cleaning coils, checking refrigerant levels, testing electrical components, inspecting belts and motors, verifying airflow, checking thermostats and controls, testing safety devices, inspecting drains, and identifying worn parts before they cause equipment failure.
Signs your commercial HVAC system may need repair include uneven temperatures, weak airflow, unusual noises, frequent cycling, rising utility bills, poor humidity control, tenant or employee complaints, system shutdowns, water leaks, or rooftop units that struggle to keep up during peak heating or cooling demand.
Yes. LSM services and repairs rooftop HVAC units for commercial properties throughout the region. Rooftop unit service may include diagnostics, filter replacement, coil cleaning, electrical repairs, belt and motor checks, refrigerant testing, thermostat and control troubleshooting, and replacement recommendations when equipment is near the end of its life.
Yes. LSM can help businesses replace aging or failing commercial HVAC equipment. Our team can assess the existing system, review building needs, recommend properly sized equipment, coordinate installation requirements, and help plan the project to reduce disruption to your business.
Repair may make sense if the system is newer, the issue is isolated, and the equipment is otherwise in good condition. Replacement may be the better option if the system is older, inefficient, unreliable, expensive to repair, difficult to source parts for, or no longer meeting the building’s heating and cooling needs.
Yes. LSM works on commercial ventilation systems, including exhaust, makeup air, ductwork, and indoor air quality-related equipment. Proper ventilation is important for comfort, code compliance, air quality, odor control, humidity control, and safe operation in many commercial spaces.
Yes. LSM works with property managers, building owners, general contractors, restaurants, offices, retail spaces, warehouses, and other commercial clients. Our team can help with ongoing maintenance, repairs, replacements, tenant improvement work, and multi-trade commercial service needs.
Yes. One advantage of working with LSM is that our team provides HVAC, plumbing, electrical, refrigeration, and specialty commercial services. For businesses and property managers, that means one company can help coordinate multiple systems instead of requiring separate contractors for every trade.
