What is the recommended frequency for HVAC maintenance?
How often you should do preventive maintenance on your heating, ventilation, and air conditioning systems will depend on your environment and how often you use them. Generally, it would help if you had a trained HVAC technician check your system and fix it at least once a year for residential and every 6 months for commercial clients. Maintenance may need to be done more often for systems that are used a lot. Another reason multiple visits per year can be helpful is that it is best to have your air conditioner serviced right before the hot summer months and cold winters.
