Comfort Air Quality & Efficiency by Design provides professional HVAC services at lower rates. From checking for and sealing leaks in your home (to save you energy and money) to cleaning out furnaces to prevent for carbon monoxide leaks, our HVAC contractor does it all.

Blower Door Testing
This process tests the air tightness of your home to detect leaks that can be raising your energy bill each month. We put a fan in the door and pull the air out of the house, which determines how leaky a house is. Our focus is on efficiency. Contact us to find out more.  Blower door testing also helps to identify leaks and inefficiencies within your home's ventilation and duct system.
