Important to respond to the issues and complaints of your tenants and keep them happy. Have your HVAC service check all operations and ascertain if they feel there is a problem and if so if they have any solutions. Is this a multi-tenant building? Any other tenants complaining? Check other possible factors - plumbing, appliances, trash receptacles, etc. Have had issues in the past in office buildings where the P trap in the drain in a slop sink in a janitor closet that was not used was allowing sewer gas to escape into the air being circulated through the building. Regularly putting water into the P trap to stop the sewer gases cured the problem. P traps are in floor drains as well and in all faucet drains - some - if not used regularly - will dry up and allow sewer gases to come in easily. Make sure your exhaust fans are working as well. AC condensate overflow drains can also be a culprit. Important to do thorough inspection and show tenant you are concerned and responding. May end up taking a while to find the issue but demonstrate to them that you are aware and concerned and taking action.
