COVID-19 Update: Your health and safety is our highest priority during this time. We are still open to serve you acting with prudence in our day-to-day operation with basic preventative safety measures. 

The Full-Service Duct Cleaning

Encompasses the entire forced-air system, from each register and return down the auxiliary duct lines to and including all the main duct lines in the ceiling of the basement that run directly off the HVAC unit using a combination of drawing and blowing of air at the same time. Once all the duct lines are cleaned, the air handling side of the furnace is cleaned to remove any loose dirt and debris from around the air conditioning coils, exterior of heat exchanger, blower compartment and the plenum, so the dirt and debris doesn’t blow back through the clean ductwork and to ensure the A/C compressor drain pan is not clogged. Before and after pictures are taken to verify the service quality.

Dryer Vent Cleaning

 

Did you know that clothes dryer vents clogged with lint are a leading cause of household fires? 2,900 home clothes dryer fires are reported each year and cause an estimated 5 deaths, 100 injuries, and $35 million in property loss. 
Vents collect direct, dander, dust and other contaminants each time you run your dryer. People often don’t recognize or ignore the signs of a clogged dryer vent, which can have disastrous results.
One call to COIT can help secure the health and safety of your home. Our trained technicians use the same exclusive HEPA-Aire™ vacuum and Aire-Sweep™ compressor system employed in our air duct cleaning service to clean the lint and debris from your dryer vents. The result: a home safer from fire, shorter dryer running times and lower energy bills.

Chimney Cleaning

 

We will clean your chimney from the inside of your home using the most advanced techniques and equipment.  Our high revolution, rotary chimney cleaning tool does a far superior job than the old standard chimney brushes.  The drill mounted, multiple bristle unit revolves around at 2000-3000 r.p.m. This insures the deepest clean available without damaging your unit. We will also use a high powered vacuum to control the dust. This along with our floor coverings will ensure no mess is left behind.

A competent chimney sweep technician will inspect the condition of the heating appliance and all its components for damage:
* The chimney cap or crown;
* The caulking around the flashing;
* The interior of the stainless-steel duct or flue tiling; 
* Supports and connectors.
The technician will also check the condition of the pipe and “tee” connecting the appliance to the chimney, whether there is sufficient clearance for combustible materials, the operation of the damper and supply air duct, the quality of the firebricks, water infiltration, corrosion, cracks, perforations, bird’s nests, and more.
These periodic checks are essential to ensure the efficient and safe operation of your heating appliance.
