Call Us for All of Your Air Conditioning Needs

We all know how hot and humid it gets in Johnston, IA during the summer months.

Do You Need Expert Indoor Air Quality Services?

Many people associate good indoor air with temperature. While this isn’t totally inaccurate, it isn’t totally accurate, either. A lot of factors contribute to good indoor air quality, including balanced humidity, clean, healthy air and good ventilation. If any of these factors are off, the quality of your indoor air will be, also. We can help balance your indoor air and make it as healthy as possible with our whole home indoor air quality products. These products integrate seamlessly with your existing HVAC system and address all the air in your home. We can also repair or replace any existing products you may already be using.

Whole Home Dehumidifiers

Too much humidity in your home can mean difficulty with allergies, extra stress on your HVAC system and discomfort throughout your home. Let us help you with the installation and expert servicing of a whole home dehumidifier!

Whole Home Humidifiers

Is the air in your home during the winter way too dry? Is your skin itchy and flaky and your throat scratchy? It’s easy to add needed moisture to your indoor air with a whole home humidifier. Our experts can install a new humidifier for you, or make sure your existing operates as you need it to with professional repair and replacement services.

Do You Need an Air Purifier?

Is your indoor air causing issues like allergy or asthma attacks? It may be time to consider a whole–home air purifier. Room air purifiers can only address the space immediately around them. A whole home air purifier cleans all the air throughout your home, making it as clean as possible.

We Offer Expert Geothermal Services

Geothermal systems are unlike any other type of HVAC system around. They have different components, are installed very differently from traditional systems and work very differently from traditional systems.

Great Plumbing Service

Based on prior experience with their heating cooling service, I requested them to fix some plumbing issues - toilet, faucet and garbage disposal. They were here in a couple days on time, very courteous and cleaned up. Their work was excellent - no leaks or call backs. I will use them again.

Matt B. and Mike M. are Superstars

If everyone in your organization is as diligent and professional as these two guys that I have interacted with in the last week, then, I am proud to do business with you. Running a service business myself, I can attest that the level of care I received is consistent with high caliber, value add talent. They earned my business and it will be up to your other technicians to steward the same level of care. Mike serviced us perfectly, when he didn't know something, he enlisted senior technicians...which brought in Matt. Matt diagnosed the issue, giving me a quote (albeit high), to fix my concerns. Matt proceeded to continue to research our concern and eventually called me back with a VERY in depth review performed, and confirming/alleviating our concerns completely. I was impressed with his follow through, research and disposition on our issue.

Great service.

He was very careful to check every thing and explained what he was doing. Thank you for sending him.

Great service

I requested Justin to do our winter service check. There was a problem with our last service call. Justin came out and corrected the problem quickly. We’ve been Schall’s customers for about 30 years.

Great Service

Ryan and Derek both were vey friendly and informative as to what and if I should keep on look out for in the coming months.

Quick Tune-Up

Very personable, great advice. Ryan and Derek were very polite and shared exactly what they were going to do. They shared the results of their findings and what their recommendations were. They were not pushy, but did share potential risks.

Emergency Service that went great

Our furnace suddenly stopped working. I tried a few basic fixes (checking thermostat batteries, circuit breakers, etc.) and made an emergency call. David came out as scheduled, and was able to fix the problem very easily (a loose door) and he was very professional. To the extent a furnace problem can be a good experience, this was a good experience.

Friendly and helpful service

Appreciate the visit on short notice
