Air Ducts

Floor vent in a house.

According to the U.S. Department of Energy’s Energy Star program, leaky ducts in attics or crawlspaces can account for 20 percent or more of a home's heating and cooling energy losses. This results in higher utility bills for you and difficulty keeping your house comfortable.

A few signs you may have leaky ducts are if you have:

  • High utility bills in summer and winter
  • Difficult-to-heat-and-cool rooms
  • Stuffy rooms that never seem to feel comfortable
  • Attic, crawlspace, or garage ducts
  • Tangled or kinked flexible ducts in your system

What Can You Do About Leaky Ducts?

Run your system, and check all the ducts and joints you can access. You can seal these yourself with mastic or foil-backed tape. You should also seal around where the duct meets the wall. Duct tape is actually not recommended for ductwork, and any fabric-backed tape will deteriorate over time. If you have questions about appropriate tape call us at 662-844-0270 or talk to a representative at your local hardware store.

The following maintenance will require an HVAC professional:

Air Duct Insulation

We recommend insulating your ducts. This ensures that the air maintains the correct temperature as it travels to the living spaces in your home.

Air Duct Testing

You can have your ducts tested. One of our certified technicians will take a reading of the air pressure in your ducts and can analyze how much air you lose. From there we can make suggestions about how to improve efficiency.

Air Duct Cleaning

You should have your air ducts cleaned. Over time, dust, mites, bacteria, and other things get sucked into your vents and build up in your ductwork. Imagine all the years of dust in your house getting blown around into the air you breathe. The professionals at M & M Heating and Cooling will clean up your ductwork, removing obstructions that restrict your airflow and cleaning out any bacteria and dirt that pollute your indoor air.

You can also have an ultraviolet (UV) light installed in the ductwork. This uses UV radiation to sterilize air, destroying bacteria as well as mold and fungal spores. This serves to greatly improve your indoor air quality.

Indoor Air Quality

Indoor Air Quality, or IAQ, is very important to the health and well-being of you and your family.
