Signs You Need Air Duct Cleaning

Posted by

Dirty, dusty or infested air conditioning ducts can cause a myriad of problems; from allergy concerns to inefficient cooling or heating, clogging of these ducts leads to bad things for your home, health, and wallet. There are visible signs you should be aware of to help you decide whether or not your home needs an Air duct cleaning.  If you notice one or more of these signs as listed below, please contact the professionals at Snyder Heating and Air to schedule your air duct cleaning.

1. Visible Mold Growth

Mold buildup in air conditioning ducts can lead to aggravated symptoms for those who suffer from allergies and asthma. Many people complain of uncomfortable reactions when mold begins to set in within the AC and heating system. Find an area where you can visibly assess the condition of your ducts and look for any surface mold. Afterwards, check other air conditioning components to make sure they are free of mold and other debris. Even a slight amount of mold can signal a much larger problem within your duct system.

2. Signs of Rodents or Insects

Hearing funny noises in your AC ducts? If you have a sinking feeling that rodents or insects have found their way through your duct system, it’s time to contact a professional. Rats and other small animals are sometimes able to chew through existing structures and make their way into the ventilation system. When these animals make a home in your ducts, they will leave waste and foot particles behind and, eventually, they may even die within the piping. Cleaning the duct system thoroughly and preventing similar incidents will help ensure your family is breathing the cleanest air possible.

3. Signs of Moisture

Moisture leads to mold and mold leads to everything you read under the first item on this list. When an air conditioning duct isn’t properly insulated or is kept at a moisture-inducing temperature for too long, moisture can build up in the duct system. Because of the nature of water vapor, transitions between seasons can lead to a gathering of moist air. When this air cools, it tends to leave small puddles within your air conditioning system. These moist conditions lead to the growth of mold and fungi of various types. Areas of high humidity, bathrooms and kitchens, are a great spot to inspect for signs of moisture.

4. Unexpected Increase in Monthly Utility Bill

A sudden increase in your power bill can be caused by various factors but an inefficient air conditioning and heating system is often the culprit. One of the easiest ways to track the dirt in your duct system is through your bills. Note any abnormal increases in use. Keeping your air conditioning ducts clean and free of any debris, mold or other obstructions can ensure that you have a predictable monthly power bill.

If you’re noticing any of the problems outlined above or if you are unsure of what is causing your air conditioning or heating system problems, be sure to call Snyder Heating and Air.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

-Linda Ackley

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

-Chuck Jr.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
