If you own a home, at some point you will be faced with the task of

choosing a company to clean your furnace and ducts.

It can be challenging because there are several companies who seem to offer the same service.

Below are the important questions to ask.


1) Equipment and ProcessAsk what type of equipment they use and if it is specific to cleaning HVAC systems. Also have them explain the process they use. This will give you a good idea of what to expect so there are no surprises.


2) Time - With two technicians the average single furnace residential cleaning should take between 2-2.5 hours.

If there are two furnaces, it should take between 3.5-5 hours.


3) PriceThe entire system including the furnace plenum, cabinet, blower, heat exchange, AC coil, ducts, and vents should be cleaned for the quoted price. Beware of any hidden fees that could be associated.


4) Are they localThis is important because a local company will take more pride in serving the community they live in. 


Asking these questions will help give you the knowledge to make a good decision.
