Harker Provides You with the Best Aprilaire Products

Few things are as important as the air you breathe.

The air you breathe in your home may be more harmful than the air outside. U.S. Environmental Protection Agency studies have shown that your indoor air can be up to 5 times more polluted than the air outside —even in smoggy, urban areas.

Aprilaire Whole-House Indoor Air Quality products work with your HVAC system to treat the air throughout your home, and can help improve your family’s health, comfort and finances by controlling temperature, humidity, air purity and air freshness.

Air Purifiers

Just like dirty water, dirty air poses a significant health risk. Especially in today’s tighter homes, airborne viruses, allergens and other contaminants are trapped inside. When you choose a genuine Aprilaire Air Purifier, you’re getting Healthier Air, period. You’re also ensuring that your HVAC system will last its maximum life-span and require fewer service trips to your home.

Temperature Control

Temperature Control

Aprilaire Thermostats play an important role in health and comfort. Heating and cooling costs are the #1 expense in most American homes. Aprilaire Programmable thermostats allow you to save energy by setting your home at different temperatures based on your schedule. Options may also include Wi-Fi control of heating and cooling as well as control and monitoring of air purity and humidity.

Ventilation system


With Aprilaire ventilation, clean fresh air is brought in while stale, musty, dusty air is removed. Aprilaire ventilation systems reduce the concentration of pollutants in your home, which can be 5 times greater inside your home than outside.
