Breathe Better, Live Better.

No matter where you live or work, it’s important to keep your air quality in pristine condition. Stephens offers many air quality services to keep you healthy and comfortable. From humidifiers and dehumidifiers to thermostats and air ducts, see how we can help you clear the air!

Humidifier Installation & Replacement

If you have dry air in your home, respiratory problems can result. That’s why installing a humidifier to help you control the air in your home can be so important. Humidifiers will help you save money on energy bills and stay healthy. There are four main types of humidifiers, and Stephens can install the right one for your home at unbeatable rates. Give us a call, and we’ll be happy to help!

Dehumidifier Installation & Replacement

A dehumidifier eliminates or reduces the humidity in any space. It does this by extracting water from cold air to make air quality more comfortable and healthy. Without a humidifier, excess humidity can increase perspiration and damage certain materials. It can also increase the presence of mold, mildew, and insects. We can help you select the right dehumidifier for any room or home and install it properly the first time.

Thermostat Installation & Replacement

Your thermostat is the brain of your heating and cooling system, continuously monitoring temperatures and regulating comfort. There are various types of thermostats available, each tailored to specific equipment, equipped with various sensors, and programmable for diverse schedules.

If you're considering installing or replacing a thermostat in your home, Stephens is here to help. We not only provide information on thermostat options but also ensure precise installation and programming for your ultimate comfort and convenience.

Air Duct Replacement & Cleaning

Air ducts connect your heating or cooling unit to your home. However, over time, they can accumulate dirt, dust, and other contaminants.

That’s why ducts need to be cleaned to ensure air quality. If air ducts are dirty, it can affect the health and comfort of your family and increase energy costs.

Stephens’ trained technicians understand how air ducts work and the best way to clean them. Our air quality services also include replacing air ducts if necessary for you and your family.

Real Reviews From Happy Customers

Sort reviews

I worked with several contractors to diagnose and fix my AC Pro mini split units. Hundreds of dollars later and hours of frustration baking in the heat because of a non-working AC, Stephens was able to properly diagnose and fix my AC within days of calling them. Oscar, Omar, and Pancho are the best technicians with a wealth of knowledge. I called them for several different issues, and they have always been reliable, consistent, professional, friendly, and good at what they do! I know if I have a problem with my AC they'll get the job done. I am hard to please and id give them 10 stars if I could. Thank you Stephens Plumbing for doing an A++++ job!
