Frequently Asked Questions About Emergency HVAC Services

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

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 more often than it should, reducing its lifespan.
  • Poor Humidity Control: The system may not effectively control humidity levels, leading to discomfort or mold problems.
If you are experiencing these issues, consult with a qualified HVAC technician to assess your system's sizing and recommend solutions..

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.

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..

What is a heat exchanger, and why is it important?

A heat exchanger transfers heat from the burned fuel to the air that circulates throughout your home. It prevents dangerous gases from mixing with the heated air, ensuring that exhaust gases are vented safely outside while clean, heated air is distributed throughout your home. A cracked heat exchanger is a serious safety hazard, as it can allow carbon monoxide to leak into your home. Annual furnace maintenance is crucial for checking the condition of the heat exchanger and ensuring safe operation.
