Quick Answers

Does Southwest Mechanical Services Inc handle commercial HVAC, not just residential systems?

Southwest Mechanical Services Inc is exclusively a commercial HVAC contractor, holding a California C-20 HVAC contractor's license and serving industries including hospitality, healthcare, education, retail, office buildings, and federal government facilities across San Diego County. The company does not serve residential customers — its installation, maintenance, service, and repair work is focused entirely on commercial and institutional buildings.

How much does a commercial HVAC unit cost?

Commercial HVAC unit costs vary widely depending on system type, tonnage, building requirements, and installation complexity, so Southwest Mechanical Services Inc provides project-specific quotes rather than a flat price. Facility managers in San Diego County can contact the company directly to get an accurate estimate for their building.

How often should commercial HVAC filters be changed?

Filter change frequency for commercial HVAC systems depends on building type, occupancy, local air quality, and equipment specifications — in San Diego County's relatively dry, moderate climate, most commercial facilities require filter changes every one to three months. Southwest Mechanical Services Inc offers preventative maintenance programs that include scheduled filter service to keep systems running at peak efficiency.
