Frequently Asked Questions About Emergency HVAC Services

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

What's the difference between a single-stage and two-stage furnace?

Single-stage furnaces have one level of heat output. They run at full capacity until the set temperature is reached, then cycle off until the temperature drops again. Two-stage furnaces have two levels of heat output: a lower setting for milder weather and a higher setting for colder conditions. This provides more consistent temperatures, better efficiency, and quieter operation.

How do I know if I have a gas leak?

Gas leaks are dangerous and hazardous. Signs of a gas leak can include:
  • A sulfurous odor
  • Hissing or whistling sounds near gas lines or appliances
  • Blowing dirt or bubbles in standing water
  • Dead or discolored vegetation near gas lines
  • Physical symptoms like dizziness, nausea, or headaches
If you suspect a gas leak, immediately leave your home or building and call your local utility provider or 911 from a safe location. Avoid any open flames or sparks.

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. A cracked heat exchanger in a furnace is a common source of carbon monoxide leaks in homes. Regular HVAC maintenance, including inspection of the heat exchanger, is important for preventing carbon monoxide leaks. Install carbon monoxide detectors in your home to alert you to dangerous levels of CO.

What are the benefits of a preventative HVAC maintenance plan?

A preventative HVAC maintenance plan can save you time, money, and frustration. Regular maintenance by a certified HVAC professional can:
  • Improve Energy Efficiency
  • Extend System Lifespan
  • Prevent Costly Repairs
  • Enhance Indoor Air Quality
  • Identify Potential Problems Early
  • Ensure Safe and Reliable Operation
By investing in regular maintenance, you're protecting your valuable HVAC equipment and extending its lifespan.
