Frequently Asked Questions About Emergency HVAC Services

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

How often should I replace my AC unit?

Air conditioners typically last around 15 years with proper maintenance. If your unit is getting old and inefficient, or if it requires frequent repairs, consider replacing it.

How do I choose the right HVAC filter?

When choosing an HVAC filter, consider:
  • MERV Rating: The Minimum Efficiency Reporting Value (MERV) indicates the filter's ability to trap particles. Higher MERV ratings mean better filtration.
  • Filter Size: Make sure you select the correct size filter for your HVAC unit.
  • Filter Type: Different types of filters are available, including pleated filters, HEPA filters, and electrostatic filters.
  • Your Needs: Consider your indoor air quality needs. If you have allergies or pets, a higher MERV filter may be beneficial.
Consult with an HVAC technician for recommendations on the right filter for your system and needs..

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 can I tell if my HVAC system is the correct size for my home?

If your HVAC system is not the correct size for your home, you may experience several problems:
  • Uneven Temperatures: Some rooms in your house might be significantly hotter or colder than others.
  • High Energy Bills: An undersized or oversized system will work harder and consume more energy.
  • Frequent Cycling: An oversized system will turn on and off too frequently, reducing its lifespan.
  • Poor Humidity Control: Incorrect sizing can cause inadequate humidity control.
If you are experiencing these issues, consult with a qualified HVAC technician to assess your system's sizing and recommend solutions..
