"WOWWW! Above & beyond service, courteous & knowledgeable technician, and fair pricing... what more could you want?! I contacted Air Control Systems via Angie's List and (literally) within minutes received a phone call. They were able to send a technician out that same day (rare in todays service industry!) at no extra charge. Nathan was very personable yet prompt. He fixed the issue, while also checking everything else out to ensure peak performance moving forward. The cost was very fair, and I will not be using ANY other company for HVAC issues in the future! Outstanding!"

"Jesus did a wonderful job. Our ducts hadn't been cleaned in forever; dirt and dust would fly constantly ever time the furnace came. Fast, efficient service. Excellent price, senior and veteran discount. Highly recommend this to anyone who is needing this service."

"I've worked with Evergreen since we purchased our home in 2020. They've done a multitude of projects for us, the most recent being installing an entirely new HVAC system (two units inside and out). They are on time, friendly, courteous, and very professional. They even put up with our rather high-strung little poodle. We had multiple companies bid our job, and we chose Evergreen both because we knew they would do a good job and stand behind their products. We also knew they would be great folks to have in our home doing work. It's never easy when contractors are in your living space, but they make it as pleasant as it can be. Thanks to Shaun and his team for doing such a great job for us, many times over!"

Heating and Air Conditioning FAQs, answered by experts

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
