"Computer had been acting up for a while but I kept putting off getting it fixed.  After reading all the great reviews, I decided to give N.A.T.S. a call.  So glad I did.   Jim was able to resolve all my problems remotely - no drop off or pick up necessary - so convenient!  I feel like I have a brand new computer, it runs so well and FAST too.  I couldn't be happier and wouldn't hesitate to use his services again.  My only regret is that I didn't call him sooner.

"On 12/9/2025, Todd F and his assistant, Conditioned Aire, cleaned out my furnace ducts. He said he accidentally cut the air conditioner coil, and he would be back when it was 70 degrees to replace it. On the receipt for the cleaning, he wrote,; A/C coil needs to be replaced at no charge to customer. Signed Todd Fand I called on 5/12/25, 5/14/25, 5/16/25, 6/2/25, 6/8/25, 6/25/25 and left a message to call me. He never contacted me. I request that the coil be replaced at no charge."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"We have used Schnieder's for almost 40 years. There staff and services should be models for other heating and a/c companies. They are consistently timely and thorough. If there is an issue, it is addressed immediately. Their staff are consistently professional. Schneider's should feel free to use us as a reference."

FAQs for ducts & vents installation and replacement projects in La Crosse, WI

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
