Professional Drain Cleaning Services for Your Home
Kitchen Drain Cleaning
Kitchen drains collect grease, food scraps, and soap residue over time, leading to slow drainage and clogs. Our trained team uses high-performance drain cleaning equipment to clear out build-up and fully restore proper water flow in your kitchen.
Bathroom Drain Cleaning
Bathroom drains often clog due to hair, shaving cream, toothpaste, and body products. We remove these materials efficiently with techniques that target common bathroom pipe issues, leaving your sinks, tubs, and showers draining smoothly.
Floor Drain Cleaning
Basement and laundry room floor drains can become blocked without immediate signs, until water starts pooling. We offer complete floor drain cleaning to help avoid flooding, especially during storms or heavy water use. Our tools can access deep or tight areas for effective debris removal.
Main Sewer Line Cleaning
A clogged sewer line can cause water to back up into several drains at once, turning into a major plumbing emergency. Our comprehensive sewer line cleaning includes camera inspections to locate the blockage and determine the best clearing method. Dunn Heating and Air Conditioning uses advanced technology to address the source of the issue, not just the symptoms.
Preventative Drain Cleaning
Routine drain cleaning is a smart way to reduce the risk of future clogs and extend the life of your plumbing. We offer scheduled maintenance services to keep your drainage system operating at its best and help prevent expensive repairs down the road.
Our Drain Cleaning Process
1
We begin by inspecting your drainage system to pinpoint where the blockage is occurring and assess how severe it is. Our technicians will ask about your experience with the problem—when it started and how it’s changed—to better understand the situation.
2
Using drain camera equipment, we perform a visual inspection inside the pipes to identify the cause of the blockage. This allows us to determine whether the obstruction is from grease, tree roots, buildup, or a foreign object, so we can apply the proper cleaning solution.
3
We then choose the right equipment for the job. Each of our service vehicles carries a range of specialized drain cleaning tools, including hydro-jetters and motorized augers to handle all types of clogs.
4
Our technicians proceed with the cleaning, thoroughly removing the obstruction without harming your pipes. The goal is to eliminate the clog and restore free-flowing drainage.
5
Once cleaning is finished, we flush the system with water to confirm proper drainage. In some cases, a follow-up camera inspection is performed to ensure the entire blockage has been cleared and no other issues remain.
