Air Ducts

An air duct vent on the floor.

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 765.471.7506 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.

Indoor Air Quality

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

Air Duct Repair in Lafayette, IN, 47901

“In June 2023 I requested a second opinion from Anderson Heating and Cooling after noticing that the new HVAC system purchased and installed by a different company was making a loud whisleing noise. Marty came out and in 10 minutes he identified several items that were improperly installed at the air handler and provided advise on corrective measures. His advise resulted in eliminating the high pitched noise. From now on, Anderson is my go to!”

Air Duct Repair in West Lafayette, IN 47906

“Richard did the initial repair and then we had two other Anderson technicians replace some ducts, add insulation and install a Honeywell 5" air cleaner access. I'm so sorry that I did not record their names!

This was a very professional job by all three of your employees. They were courteous, thoughtful and knew exactly what was necessary. As a result, we will be contracting Anderson for our heating and cooling inspections as well as our HVAC needs.”

Furnace Maintenance in Lafayette, IN 47909

“I had a very, very old furnace and A.C unit; it was from the 1970’s. I have had a local company come out and “tune up” both units numerous times with a price of approximately $300.00 each time for the past 4 years. It just so happened this past June, our furnace officially broke. As a result, I called our “usual company” that had been servicing the units for years. That company didn’t show me in person what was wrong with the furnace; they just showed me a picture. I decided it would be best to replace the unit at this point, however their financing options were horrible. The temperature outside was around 98 and very humid, like all Indiana summers are, so I called JL Anderson and spoke with Kurt. He was at our house within the hour to inspect the furnace. Kurt confirmed the unit needed to be replaced. He explained the financing options; they were reasonable, affordable, and easy. Everyone at JL Anderson Heating & Cooling was wonderful! Since I didn’t have any A.C, Kurt and the ladies in the office attempted to ensure my family was comfortable by offering fans and window units until the new unit could be installed. Although we had to wait 2 weeks for the new unit to come in, JL Anderson Heating & Cooling worked quickly and kept us informed of any changes. When the furnace arrived, Kurt and the other workers were very polite, clean, and professional. They even replaced some of the attic vents that were ripped! That night I noticed that the air wasn’t getting colder in my house. Though it didn’t have anything to do with the furnace, I called JL Anderson first thing the next morning. They quickly sent Jacob out that afternoon. Jacob noticed right away that something was not right. He checked the line, the pressure, assessed it, and continued to be baffled by what it could be. Jacob didn’t rush though; he didn’t want to leave until the problem was taken care of. It was late, I am sure he was suppose to be off work, but he remained professional and polite the whole time. Eventually, he took the A.C. unit cover off and immediately realized what the problem was. The original company (who had replaced the motor and fan, as well as come out multiple times to service the unit) put the motor and fan in backwards 4 years ago! Therefore, for the past 4 years I have been spending a lot of money trying to keep my house cool, though unsuccessfully, due to a huge installation error made by that company! Needless to say, I was more than a little angry to discover I had been repeatedly paying to fix their mistake! However, I was also extremely happy that I finally had a working A.C. unit in my house after all these years! I was ready to write a check for whatever they asked, but Jacob looked at me and said, “Don’t worry about it.” What company does that? JL Anderson Heating & Cooling actually values their customers so much they waived some fees for me since I had just hired them for a furnace replacement, but was still having issues with my other unit! I will never, EVER go anywhere else again. JL Anderson Heating & Cooling is the best!”

AC Installation and Duct Work in Lafayette, IN

“When our A/C unit quit on us a couple of months ago we called JL Anderson, since we had used them in the past. Joe came by, evaluated our A/C needs, including the current duct work and suggested a change to the existing duct work which would make the upstairs much more pleasant. The price for the new A/C unit and the additional duct work was very reasonable. On the day of the install, Joe stopped by along with the crew and went over the days work with us. The work was done impeccably and the place was left in very good condition after the job. Joe stopped by a few days later to ensure that everything was working fine. Our upstairs is so much more comfortable after Joe’s duct work suggestion!!!! All in all, we’re very pleased with the work by Joe and the team at JL Anderson.”

Cooling Repair in Lafayette, IN 47909

“I will trust no other heating and cooling business. JL Anderson helped us solve a cooling problem that another company wanted us to simply put in a larger unit. The problem was the duct work. We put in a separate system and are comfortable.”
