It's that time of year to make sure the 2021 3.5 ton Carrier is up to the task of keeping me cool during the long, hot summer months, and the fourth cooling season for this unit.
After making sure power is disconnected, the most important thing shown, is the condenser coil cleaning, to ensure good air flow for proper operation. I decided to test the dual capacitor, and it checks out ok. However, I always keep a spare on hand, as well as a contactor, since they are very common failure points. Will be picking up a spare condenser fan motor this year. All the cleaning, touch up paint, and waxing is personal preference, and not necessary to ensure proper operation.
After I finished up with the condenser unit, I go inside, and replace the filter, so I have proper air flow on that side of the system as well. Heat wasn't used that much, and the filter reflected that. I'm sure the filter installed in this video will make it just over one month.
