Regular maintenance guarantees that your cooling system operates at peak efficiency and that any possible issues are identified early. It also helps to prevent more expensive repairs later on down the road. When servicing your air conditioner, the general rule is to get it done at least once a year. Your system will function more efficiently and survive longer as a result. Additionally, it's a good idea to get your air conditioner serviced twice a year if it is subjected to harsh weather, such as high heat or cold.
