While you can certainly attempt to repair your HVAC yourself, it’s not recommended. HVAC systems are made up of extremely complex machines, with hundreds of intricate parts. Accidentally breaking any one of them can call for costly repairs that can end up costing you even more. Self repairs will also cancel out any warranty on your unit. That’s why we recommend you choose to work with an experienced HVAC technician who’s been trained to skillfully diagnose and repair your HVAC system.
