Our Services

What Does an Air Handler Do in Your HVAC System

The air handler is the indoor component of your HVAC system that circulates conditioned air throughout your home. It works alongside your heat pump or air conditioner to pull in return air, pass it over the evaporator coil, and push cooled or heated air through your ductwork. Without a properly functioning air handler, your system can’t distribute air efficiently, no matter how well your outdoor unit performs.

Signs Your Air Handler Needs Repair

If your system isn’t keeping up with demand, the air handler could be the source of the problem. Some common signs to watch for include:

Your home has rooms that feel warmer or cooler than others, pointing to uneven airflow.
You notice weak or little airflow coming from your vents even when the system is running.
You hear unusual sounds like rattling, squealing, or banging coming from the unit.
Your energy bills have gone up without a clear change in how you use your system.
Ice is building up on the evaporator coil, which can signal a refrigerant or airflow issue.
The system is turning on and off more frequently than it should.

In Crystal Lake, IL, humid summers put extra strain on air handlers. When moisture levels are high, your system works harder to dehumidify and cool your home, which can accelerate wear on internal components.

Common Air Handler Problems We Fix

Our technicians are experienced with a wide range of air handler issues, including blower motor failures, dirty or frozen evaporator coils, worn fan belts, electrical faults, and clogged filters that restrict airflow. We also address drainage problems that often come with the high humidity levels Crystal Lake sees through the warmer months.

Air Handler Installation & Replacement

If your air handler is older, has needed repeated repairs, or simply isn’t keeping your home comfortable, replacement may be the smarter investment.

What Your Neighbors Are Saying About Us

I've been using WeatherWise for years and always happy with the service.

They are always on time and best of all, reasonably priced. It's hard to find a company in that industry that you can trust. They have been there when I needed them. I trust WeatherWise and have recommended their service for my neighbors who are also very happy. I recently had them install a new furnace and air conditioner and was surprised that both were installed in less than a day. Keep up the good work!

I had weather wise come out to my home to put on a new humidifier.

They completed the job quickly, professionally, and explained how everything worked to me and my husband. When the crew was finished, they left our basement neat, clean and tidy. For the price, you really can't beat their great service!

Weatherwise is amazing.

I can tell you that these guys really know what they are doing, they are priced very fair, and treat you like friends and family. Of all the service companies I have dealt with in my time they are by far the best. Frank, on behalf of my family and my self we thank you from the bottom of our hearts for your service. A new furnace 2 days before -25 degree temps is a huge relief. Thanks again and we will see you next fall for service.

Frequently Asked Questions

How long does an air handler typically last?

Most air handlers last between 15 and 20 years with regular maintenance. If yours is approaching that range and needing frequent repairs, replacement is worth considering.

Can I run my AC if the air handler is having issues?

Running your system with a known air handler problem can cause further damage. It is best to have it looked at before continuing to use it.

How does Crystal Lake's humidity affect my air handler?

High summer humidity makes your air handler work harder to remove moisture from the air. This added strain can shorten the lifespan of components if the system isn’t properly maintained.

How often should I replace my air filter?

Most filters should be replaced every one to three months. Homes with pets, allergies, or higher dust levels may need more frequent changes.

Do you offer emergency air handler repair?

Yes. WeatherWise Heating & Cooling, Inc. offers emergency repair services so you are not left without comfort when it matters most.
