Water Heaters

Doornbos Heating and Air Conditioning is happy to offer our Mount Greenwood, IL, customers two options when it comes to water heaters.

Many people are familiar with the traditional water heater. It works by storing water in a tank and keeping it heated to a preset temperature.

A tankless water heater is a new idea to many people. How does it work? As the name implies, there is no tank to store water. Instead, water is heated on an as-needed basis. A couple of the key benefits of a tankless water heater are that you are not heating water until it’s needed and you won’t run out of hot water.

Let the water heater professionals at Doornbos Heating and Air Conditioning help you determine which type of water heater is best for your situation.

Indoor Air Quality

Between work and home life, the average person spends about 90 percent of their time indoors. Indoor air can be two to five times more polluted than outside air. In fact, the US Environmental Protection Agency (EPA) ranked indoor air quality (IAQ) as a top five environmental danger.

A well-insulated home can help with your energy bills by keeping a constant temperature, but that also leads to the same air being recycled through your home each time you run your air conditioner or furnace. Be sure you have proper filtration in place to prevent allergens and bacteria from circulating through your air.

Doornbos Heating and Air Conditioning can help you breathe easy. Call us today at 708-423-9580, and we can put together a plan for your home.

Learn more about indoor air quality.


According to the US Department of Energy’s ENERGY STAR® program, leaky ducts in attics or crawl spaces can account for 20 percent or more of a home’s heating and cooling energy losses. This makes it difficult to keep your house comfortable and can result in higher utility bills. Some signs you may have leaky ducts include:

  • High summer and winter utility bills
  • Rooms difficult to heat and cool
  • Stuffy rooms that never seem to feel comfortable
  • Ducts located in an attic, crawl space, or garage
  • Tangled or kinked flexible ducts in your system

Learn more about how you can detect, prevent, and fix air duct issues with the help of our professionals at Doornbos Heating and Air Conditioning. Find out more about duct testing, duct insulation, and duct cleaning, as well as how they relate to and impact indoor air quality.

Humidifiers and Dehumidifiers

The comfort of your home not only depends on the air temperature but also the amount of moisture in the air.

Cold weather typically means dry, uncomfortable air. Dry air can cause respiratory problems as well as damage wood furniture. Whole-house humidifiers emit water vapor to increase the humidity in your home.

On the other hand, hot weather can mean thick, humid air. This can lead to condensation on your windows, mold spots on walls or ceilings, and blistering paint or peeling wallpaper, just to list a few issues. A whole-house dehumidifier removes excess moisture from the air in your home.

Whole-house humidifiers can improve your indoor air quality, as well as positively impact the overall health of your family and health of your home. Controlling the humidity in your home will help protect not only your respiratory system but also your wood floors, furniture, and artwork.

Let our professionals at Doornbos Heating and Air Conditioning help you decide what’s best for your home. Call us at 708-423-9580 or request service online today.

The job was done in one day and the installers Nick and Javier did an excellent job. They worked quietly, efficiently and cleaned up extremely well.

Air Conditioner Installation in Tinley Park, IL, IL 60477

“Jamie and Nick did a fantastic job. They were very professional and knew what they were doing. We installed new furnaces and air conditioning units. They used the information in the installation manuals when they were taking their readings and had to make adjustments from the factory settings so the units would perform properly for my home. They gave me a form with all of the readings filled in so if we ever have a problem, the service technician will know how the units were performing when they were brand new. They didn't talk much until the installations were complete, and then explained everything in detail and answered all of our questions. Very impressive!”

– George R.

Air Conditioner Maintenance in Oak Lawn, IL 60453

“We have been with Doornbos for at least 30yrs or more. We have had the best service! Today we had yearly maintence on our air conditioner. We had Juan Garcia do the service. He was very polite, and knew what he was doing! He did an excellent job! We always recommend Doornbos to neighbors and friends.”

– Lorraine A.

Air Conditioner Repair in Palos Heights, IL, 60463

“If you are working with any other heating and and air conditioning company you are making a mistake. I have been with them 30 years and the level of service is always the best. Hottest day in 10 years my AC has an issue. They are at my house in 3 hours. Joyce in the office is just wonderful, she always treats you like a friend. The service guys are all great. Dan fixed my AC and told me it was no charge as my warranty is 10 years parts and 5 on service for new units. This company is the best.”

– Bill F.

Air Conditioner Repair in Burbank, IL 60459

“My air conditioning conked out on the first hot day of the year. Even though Doornbos was swamped with service calls because of the sudden onset of the heatwave Joyce who answered the phone was very friendly and understanding of my situation. As soon as was possible a technician was sent to my house. Dan was the man who diagnosed my problem, a burned out motor, and everything is back to working as it should be. Because my air conditioning unit is quite old Dan had to work around a couple problems in order to make the new motor fit. He was not happy until he was satisfied that everything was perfect. Dan's friendly demeanor and competent work are assets to Doornbos.”

– Peter P.
