Improving the Efficiency OF Your System’s Return Vents

Improving the Efficiency OF Your System’s Return Vents

When it comes to HVAC, your system is only as great as its weakest link. You might have the most efficient heater and air conditioner on the market. But you are throwing money away if you forget about maintaining the ventilation aspect of your system, primarily your return vent. Without proper air flow, both your heater and air conditioner cannot work at its best. So, it is important that your return vent gets some attention, too.

Performs An Important Job

The job of the return vent is to pull in air from your home to be warmed or cooled. After the air has been treated, the air is pushed out of the air vents located throughout your home. The quickest way to improve the efficiency of your return vents is to make sure that you regularly change the filter in your furnace. A dirty air filter will act as a bottleneck to the air that has been drawn in by your returns. When this happens, the efficiency of your HVAC system suffers.

Size and Placement Matters

Depending on the size and layout of your home, you might have one or more return vents installed. The rule of thumb is that you want to have as much air going to your return vent as possible. To make sure this is possible, the grilles on your vents should allow for maximum airflow. You will also want to make sure your vents are not blocked by furniture, rugs or drapes that will impede airflow. Some homes have two sets of return vents with some higher up on the wall for warm air and some placed lower on the wall for cool air. If you have this type of set up, you would close the lower vents during the summer and the higher vents during the winter.

Keep Your Vents Open

Don’t make the mistake of closing returns or air vents around your home by thinking that you are making your system more efficient. When you close vents around your home, you create pressure in your home’s duct work that can cause damage to your ducts and your system.

Include in Your Cleaning Routine

Because your return vent is continually sucking in air, it is also sucking up dust, pet hair, pollen and other contaminants in the air. This will cause a buildup in the form of dust in the grille covering the vent. Make it a habit to remove this dust regularly with your vacuum’s brush attachment. This will help keep your return vent cleaner, improve the efficiency of your heater and air conditioner and it will prevent contaminants from getting into your system.

Regular maintenance of your home’s HVAC system, including professional cleaning of your return vent is important to keeping your system running efficiently and for improving its lifespan. Get back on track with maintaining your system by scheduling service with Snyder Heating & Air Conditioning.

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.

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

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.
