I've tackled some basic maintenance on my HVAC system like cleaning the filters and checking airflow. However, it's still short cycling every few hours. Before reaching out to a technician, are there any additional DIY steps I should consider, or is it best to get a pro involved at this point?

If the system's short cycling is confusing, it might be time to call in a reputable professional. Just to clarify, when you say it short cycles, do you mean it runs okay for a while and then shuts off repeatedly? It could be several things, so getting an expert’s eyes on it might save you time and hassle.
Have you checked the drain line for the interior unit? A clog there could really mess things up! One HVAC company advised us to pour a quarter cup of bleach down the drain line every few months in the off-season and monthly during summer to prevent blockages. It's a small step that can help with a lot of HVAC issues.
First, I recommend checking the model numbers for your equipment online. You might find common issues or solutions specific to your model. Watching YouTube videos related to your HVAC system can also give you some helpful hands-on guidance. And if your thermostat has a battery, definitely replace that too; a simple fix might make a difference.
