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 too frequently, which can lead to premature wear and tear.
  • 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..

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 help prevent pipes from freezing.
  • Let Faucets Drip: During extremely cold weather, allow cold water taps to drip slowly 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 carbon monoxide, and how can it affect my HVAC system?

Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that is dangerous when inhaled. Malfunctioning fuel-burning appliances, like furnaces or boilers, can produce carbon monoxide. CO can leak into your home if the heat exchanger in a furnace is cracked. HVAC maintenance checks can detect CO risks. CO detectors save lives.

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.
If you notice a musty odor or visible mold, contact a professional.
