Frequently Asked Questions About Emergency HVAC Services

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

How can I prevent mold in my HVAC system?

Mold growth in HVAC systems can cause health problems and reduce system efficiency. To minimize the risk of mold in your system:
  • Control Humidity: Keep indoor humidity levels between 30% and 50%.
  • Regularly Change Air Filters: Change your air filters frequently.
  • Clean Drip Pans and Condensate Drains: Regularly inspect and clean your AC unit's drip pans and condensate drains to prevent standing water.
  • Ensure Proper Ventilation: Adequate ventilation helps to reduce moisture buildup.
  • Schedule Professional Duct Cleaning: Have your ducts professionally cleaned every few years to improve indoor air quality.
Consult with a qualified HVAC technician if you suspect mold growth in your HVAC system.

How can I prevent future HVAC emergencies?

Preventative maintenance is the best way to minimize HVAC emergencies. Regular maintenance can help identify potential problems before they escalate into emergencies. It is recommended to have your system inspected and serviced by a qualified HVAC technician regularly, typically once in the spring and once in the fall. Regular maintenance can also improve your system's efficiency, extending its lifespan and potentially saving you money on energy bills.

How can I prevent frozen pipes in the winter?

Frozen pipes are a common HVAC emergency in cold climates. Protect your pipes from freezing by:
  • Insulate Pipes: Insulate exposed pipes in unheated areas, such as crawl spaces, attics, and garages.
  • Seal Air Leaks: Seal air leaks and cracks in walls and foundations near pipes.
  • Keep Thermostat Consistent: Maintain a consistent thermostat setting, even when you are away, to keep indoor temperatures above freezing.
  • Open Cabinet Doors: Open cabinet doors under sinks to allow warmer air to circulate around pipes.
  • Let Faucets Drip: During freezing temperatures, allow faucets to drip slightly to keep water moving and prevent freezing.
{If you suspect a frozen pipe, turn off the water supply and contact a plumber.. | Thawing frozen pipes requires caution and should be done by a professional.

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 separates the combustion process from the circulating air, ensuring that only heated air is distributed. Regular inspection of your heat exchanger is vital for preventing CO leaks. Consult with an HVAC professional if you suspect a problem with your heat exchanger.

How can I prevent mold in my HVAC system?

Mold growth in HVAC systems can cause health problems and reduce system efficiency. To minimize the risk of mold in your system:
  • Control Humidity: Keep indoor humidity levels between 30% and 50%.
  • Regularly Change Air Filters: Change your air filters at least every three months.
  • Clean Drip Pans and Condensate Drains: Regularly inspect and clean your AC unit's drip pans and condensate drains to prevent standing water.
  • Ensure Proper Ventilation: Adequate ventilation helps to reduce moisture buildup.
  • Schedule Professional Duct Cleaning: Have your ducts professionally cleaned every few years to remove mold and other contaminants.
Consult with a qualified HVAC technician if you suspect mold growth in your HVAC system.

How can I prevent future HVAC emergencies?

Preventative maintenance is the best way to avoid HVAC emergencies. Regular maintenance can help identify potential problems before they escalate into emergencies. It is recommended to have your system inspected and serviced at least twice a year, typically before the start of each heating and cooling season. A little preventative care can go a long way in keeping your HVAC system running smoothly and avoiding unexpected repairs.

  • Open Cabinet Doors: Open cabinet doors under sinks to help prevent pipes from freezing.
  • Let Faucets Drip: During freezing temperatures, allow faucets to drip slowly to keep water moving and prevent freezing.

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 separates the combustion process from the circulating air, ensuring that only heated air is distributed. 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.
