Yes, we offer thorough electrical inspections as part of our HVAC services. Our licensed electricians check wiring, circuits, and connections to ensure your heating and cooling systems operate safely and efficiently. This is especially important for older homes in the area, where outdated electrical components can affect HVAC performance and safety.

For uneven cooling, we diagnose issues like ductwork imbalances, insulation gaps, or undersized systems, then provide solutions such as duct sealing, zoning systems, or unit upgrades. For air handler fan failures, we repair or replace motors, belts, and components, often caused by dust accumulation or wear in our humid climate. Our local experience helps us quickly identify and fix these recurring problems.
