About this pro
The Best Equipment
Our proprietary truck-powered vacuum is 30 to 40 times as powerful as the rotary-brush type vacuums that end up doing more harm than good. This ensures that all foreign materials loosened from the sides of the air ducts are pulled into the filter compartment on the truck.
The Most Experience
Duct Doctor has been a single-focus Air Duct Cleaner since 1985. Technicians are uniformed and well-trained by NADCA Certified Air System Cleaning Specialists and perform cleaning using the source removal procedures.
The Duct Doctor Process
The rigid and non-collapsable vacuum hose is inserted into both the return and the supply ductwork. Once all the debris and contaminants have been dislodged and airborne inside the ductwork by the air-driven agitation devices, the powerful vacuum unit will remove it safely outside the home.

Best Questions to Ask a HVAC Technician Contractor
What is your projected timeline for the HVAC project in Raleigh?
Though a standard question, it's important to ask. Most contractors will tell you how long they expect the job to take without you asking. If they don't volunteer that information, be sure to ask. It's also helpful to ask if that's a hard finish date, meaning that it's the definite finish date. If it's a soft finish date, it may be extended for any number of reasons.
How long have you been in HVAC business for/How long have been serving the Raleigh area?
You'll always want to ask how long the company has been in business in Raleigh. While this isn't a guarantee that the company will do good work, companies with longevity on their side must be doing something right. That being said, there are newer companies that do great work. If the company is under three years old, ask where the owner was employed before and for how long. If he/she has a long history of employment, it's reasonable to infer that he or she decided to go into business for themselves after so many years of experience.
Do you hire properly documented HVAC workers?
This will be answered when you ask if all employees are licensed. The only way to obtain a legitimate tradesman's license is to be a legal or naturalized citizen of the US. The company may employ people in positions that don't require a license, however, so it's wise to inquire.
How many contractors do you have working for you? How many vehicles are in your fleet?
This is important mostly for larger jobs. Clearly a two man operation is going to build a home much slower than a 15 man crew. This is also a good indication of the overall size of the HVAC company, if that's an area of concern for you. The reason you may want to ask about the fleet is that fleet size is a good indicator of the mobility of the company. Mobility may not sound important, but it's hard for the Raleigh contractors to get to job sites if they lack appropriate vehicles.
