Frequently Asked Questions About Emergency HVAC Services

Find answers to common questions about emergency HVAC repair and 24/7 HVAC services.

What should I do while waiting for an emergency HVAC technician?

While waiting for an emergency HVAC technician:
  • Safety First: If you suspect a gas leak or any electrical hazard, evacuate your home or building immediately and contact your utility company or emergency services.
  • Turn Off Your System: Turn off your HVAC system at the thermostat to prevent further damage.
  • Document the Issue: If possible, take photos or videos of the problem to show the technician.
  • Gather Information: Have your HVAC system's model and serial number readily available, along with any warranty information.
  • Clear Access: Ensure clear access to your HVAC system for the technician.
  • Prepare Questions: Write down any questions you want to ask the technician.

What is carbon monoxide, and how can it affect my HVAC system?

Carbon monoxide (CO) is an invisible and odorless that is dangerous when inhaled. Furnaces and other fuel-burning equipment produce carbon monoxide if they malfunction. A cracked heat exchanger in a furnace is a common source of carbon monoxide leaks in homes. HVAC maintenance checks can detect CO risks. Install carbon monoxide detectors in your home to alert you to dangerous levels of CO.

How can I cool my home efficiently?

To cool your home efficiently:
  • Raise Your Thermostat: Set your thermostat to a higher temperature when you’re away. Consider using a programmable or smart thermostat.
  • Use Fans: Fans can circulate air and make you feel cooler, allowing you to raise the thermostat a few degrees.
  • Close Window Coverings: Keep curtains or blinds closed during the day to block out sunlight.
  • Limit Heat-Generating Activities: Avoid running heat-producing appliances (ovens, dryers) during the hottest parts of the day.
  • Annual AC Maintenance: Schedule yearly maintenance for your air conditioner to ensure it's running efficiently.
  • Plant Shade Trees: Planting trees around your home can provide natural shade and reduce heat gain.

How do I reset my HVAC system?

If your system isn't working correctly, you can try resetting it before calling a technician. Follow these steps to reset your system:
  1. Turn off the system: Switch off your HVAC system at the thermostat.
  2. Turn off the power: Locate the circuit breaker for your HVAC system and turn it off.
  3. Wait: Wait at least 5 minutes for the system to completely power down.
  4. Restore power: Turn the circuit breaker back on.
  5. Turn on the system: Switch your HVAC system on at the thermostat.
If the problem persists after resetting, you likely have a more serious problem and should consult with a professional.
