Your HVAC system can cause serious indoor environmental problems leading to health issues and energy waste. Leaking air ducts waste energy and lead to cross-contamination of conditioned spaces in the home or mold spores and other allergens. Oversized air conditioners waste energy and contribute to mold and bacteria growth inside the HVAC system. Worn out systems and poor-quality work can also lead to safety problems. STA mechanics will make sure you are aware of the initial repair or replacement assessment options, as well as our recommendations for the most cost-effective course of action. Your interest is our priority.
