Inspect, Diagnose & Repair – Dryer Vent Cleaning

This how "K&K Air Duct Cleaning Services" will inspect, diagnose, and repair your dryer vent problems to make sure your dryer vent is safe and up to code. These are some of the codes and guidelines that we have simplified to make it easier for homeowners to understand. We use IRC and IMC codes as well manufacturers best practices to inspect dryer vents.

Get Your Air Duct Cleaned

We start with the basics:

• check for disconnected ducts
• moisture problems
• broken ducts
• clocks
• incorrect material

A clothes dryer will vent about a gallon of water for each load of laundry. If the dryer vent is disconnected and in a crawlspace, attic, or other building cavity, the potential for moisture-related damage is significant.
We find a lot of rotten roof sheeting because the dryer was venting inside the attic. Mold problems are common as well when a dryer is leaking air or venting inside the house.

The Duct

According to the requirements of the 2009 International Residential Code (IRC) M1502, the clothes dryer exhaust duct should be made of metal, with No. 28-gauge thickness, a smooth interior finish, and a duct diameter of 4 inches.

Transition: the most commonly overseen dryer vent problem

A transition is the visible piece of duct connecting the dryer to the wall duct. It is allowed to be up to 8 feet long and should never go through the wall. Transition ducts must be visible and not concealed within construction.
Most ducts made of vinyl, nylon or foil are not recommended. If used, they will void the warranty of most dryers. These flexible accordion type designs because:

• do not meet code sizing and material specifications
• they trap lint,
• obstruct the air flow
• clog the duct
• require the dryer to work harder
• longer to dry clothes
• cause increase of dryer’s temperature
• wastes energy


The termination outside the building should be located at least 3 feet from any other building opening, and at least 10 feet from an air conditioner or heat pump condenser. The duct termination should be fitted with a closeable damper (a backdraft damper).
A mesh may not be installed at the duct terminus (2009 IRC M1502.3), as it can trap debris, which poses a fire hazard.
• Check the termination for birds’ nests, debris and damage.


Problems of Dryer Venting

The 10 top dryer vent problems:

• Clean the lint filter before or after each load of laundry.
• Remove any visible lint within the dryer.
• At least once a year, have a professional technician clean the dryer exhaust pipe.
• Gas dryers should be cleaned and serviced regularly by a professional.
• Install a smoke alarm in the laundry area.
• Install a CO alarm in the laundry area for a gas dryer.
Call or email K&K Air Duct Cleaning Services to have your dryer inspected or cleaned if you prefer a professional to do it for you.

The services performed were for 2 HVAC duct & vent cleaning as well as the dryer vent cleaning. I was initially notified the technicians would arrive between 12 to 2 PM, but they arrived a lot earlier at around 11:40 AM which was even better. They also called me at 11 AM to let me know they'd arrive earlier.The technicians were Mohamed and Samuel. They both wore masks and shoe covers while indoors as expected. Very polite and professional while they were at my house. All in all, they were done with everything in about 2 hours. These guys were efficient and yet, very thorough with everything they did and I couldn't be happier that I chose K&K to service my home, which hasn't had the air ducts cleaned in 10+ years. The air quality in the house has improved noticeably after the cleaning as done.K&K Air Duct Cleaning wasn't the cheapest option we found. Prior to contacting This company , we got 3 other quotes that were perhaps ~$200 cheaper for the overall package, but after seeing the quality of service provided by K&K , we knew we made the right choice. Quality work does have its price tag. K&K was also the only vendor of all that actually provided me an estimated price after I used their website to request a quote, not to mention it was extremely quite (probably within 10 minutes after I submitted the request). I had to call the other vendors to get quotes from them since none of them provided me an estimated price by email even though they had online forms to fill out for quotes as well.We will definitely contact K&K again for future HVAC & vent cleaning.

We used K&K Air Duct Cleaning for the first time and we are very pleasant with their professional and responsiveness. Sarah was very welcoming and helpful. She was also very knowledge by answering all the questions we asked. Mohamed and his partner were also very professional and willing to meet our accommodation needs. They were very patient and took their time to check the system and clean them out. They showed us how much debris out there and that explained why we experienced some allergies lately. We were very glad that we hired them and we would definitely use their service again in the future. Thank you for everything!

K&K guys arrived with masks and shoe covers and were on time for the scheduled dryer vent cleaning. Set up was not too invasive and they left everything as they found it when the vent cleaning was done.They were all very friendly, professional and knowledgeable. I would recommend them to others and do business with them again.

Great company. The technicians arrived on time and explained which services they thought we needed/didn’t need. The technician said we only needed air duct cleaning and not dryer/furnace cleaning. He saved us a lot of money!
