We recommend having your AC serviced twice a year, once in the fall and once in the spring. Following this schedule can prevent issues during seasons where the weather can be more severe. However, extreme weather like Tucson's dust storms might cause damage to your system. If you suspect this is the case, give us a call!
A good rule of thumb is every three months. However, factors like the manufacturer, the system, and your living situation can change that. If you have pets or a high number of residents in your household, or an older system, you may need to have your filters changed more often.
Not changing your AC filter can lead to dust and debris gathering and clogging your system. At best, you might notice poor air quality, but continually putting this task off can eventually lead to system failure. We recommend signing up for our preventative HVAC maintenance program to make staying up-to-date on this task easy.
Unfortunately, it honestly depends on the type of service needed for your AC unit. Give us a call, and we can give you a no-pressure estimate for your situation.
If your AC unit is experiencing issues, you might notice unusual sounds coming from it, poor air flow, poor cooling or heating, or unexpectedly high electric bills.
