How to Improve Airflow in Your Home’s Air Conditioning System
3 Steps to Better Airflow and Better Comfort
When your home never seems to cool down, it’s easy to assume you need to lower the thermostat. But if some rooms stay warm while others feel chilly, poor airflow could be the real problem. Turning the temperature down even further usually won’t fix the issue, and it can send your electric bill soaring.
Your cooling system depends on steady airflow to keep your home comfortable and operate efficiently. When air can’t move freely through the system, your A/C has to run longer and harder to reach the desired temperature. That extra strain can increase energy costs, reduce comfort, and contribute to unnecessary wear on important components.
Fortunately, improving airflow is often easier than you might think. Many solutions are very low-cost or are even simple DIY projects you can tackle in just a few minutes. A few small changes can help your system cool more evenly, improve efficiency, and keep your home more comfortable all summer long. Here are three steps to take now.
1. Professional Maintenance
A professional tune-up of your air conditioning system is the best way to ensure that it’s operating properly. Our technicians will perform a multi-point check of internal parts, cleaning and calibrating motors, blowers, and condensers, and checking refrigerant levels.
We’ll be able to correct problems you might not notice, like a blocked drain line, which can lead to bigger, more expensive problems if left unchecked. Have a service plan with us? Your tune-up is included.
2. Follow-Up Care
Annual maintenance by a pro is essential for efficient performance, which helps keep energy costs in check. But like flossing between dentist appointments, there are easy do-it-yourself measures you can take to ensure air can flow freely and keep your rooms comfortable without driving up energy costs.
Change the filters regularly, more often if you have pets. It’s easy and can make a huge difference in how hard your cooling system needs to work. If you’re not sure how to do it, we’ll be happy to show you how when we do your tune-up.
You should also walk through your home regularly, keeping an eye out for furniture, drapery, and rugs that might be blocking vents.
Finally, switch the fan setting on your thermostat from “auto” to “on” to keep air flowing to hard-to-cool spots.
3. Consider Problem Spaces
Additions and converted spaces like attics and garage apartments may not be connected to your home’s main duct system. In addition, they may have less insulation, making it harder to maintain a comfortable temperature. Rather than the costly work of expanding your ductwork, the best solution could be installing a ductless mini-split unit, which can provide super-efficient cooling to these types of spaces and supply heat, too.
