Common signs you need HVAC repairs

You don't always have to wait until your air stops flowing entirely to call a local professional. There are several telltale signs of a failing HVAC system. Contact us right away if you notice:

• Odd sounds-whistling, rattling and buzzing are all clear indications that there's something wrong with your system.
• Poor airflow-if you feel hot and cold spots throughout your home, it's time to schedule repairs.
• Odors and allergy issues-pathogens, odors and contaminants can build up in your air without a properly working HVAC system.

Without consistent airflow, mold can start to grow in as little as two days. If you smell mold or mildew, reach out to us for professional repairs.
