Services
Ralph's Heating & Air Conditioning is a 3rd generation, family-owned and operated company founded by Ralph J. Heritage in 1945. The company was established with the intentions of operating a business of honesty and customer appreciation. These are characteristics which we still adhere to today 70 years later.
At Ralph's Heating & Air Conditioning, we understand that when it comes to your comfort and the overall associated costs, no other single system in your home plays a larger role or has more of an impact than your heating and air conditioning system. Equipped with decades of experience serving Lansing, Englewood, Washington Park and surrounding areas of Southern Chicago IL, our goal is to help keep your HVAC system running efficiently, year-round.
At Ralph's Heating & Air Conditioning, we proudly provide full-service HVAC maintenance and repair services for commercial and industrial customers in Dolton, Beverly and surrounding areas of the South Side of Chicago IL to ensure ongoing system efficiency, warranty compliance and quick repair. Our commercial maintenance plans can keep your building operating costs low and ensure you get the most from this asset.
Indoor air pollution can actually be worse for you than outdoor pollution! People spend the majority of their lives inside, so clean indoor air with low levels of dust, particulates and contaminants and the right level of humidity is more important for day-to-day health and comfort. If you want cleaner, healthier indoor air, we can help supply and install the latest indoor air quality products including air purifiers and humidifiers.

Ralph's has been servicing our furnace and air conditioning system for years, and have never disappointed. There fees are comparable to other companies we've used in the past. There is never a problem scheduling a service appointment that's suitable to our convenience. The owners and technicians give honest feedback, and they do great work. I would recommend them to my family and friends.

I want to give a huge thank you to Lamar! My air conditioner went out yesterday and I was very concerned given there is a heat wave expected in the City this weekend. Lamar quickly diagnosed the issue. The problem was resolved and he identified other issues that may arise, which I truly appreciate.

We had used them in the past when they were local and family owned. They have since changed ownership and lost us as a customer. Their trip charge, service fee or whatever they want to call it is outrageous.

Moved into an old home with radiator heating & we started having issues with the boiler. We had Ralphs to come out because their sticker was on our boiler. They came out to diagnose the problem & the tech found that our water feeder needed to be replaced. After my husband did more research we started to realize we may just need to replace the whole boiler because ours was at least 30 years old. We had several companies to come out to quote us for a new boiler including Ralphs. And even though one company quoted us less than what Ralphs quoted us we still went with them because since they

I was referred to Ralph's by another service provider located in the suburbs. Ralph's customer service was excellent. The response was incredibly timely. Carl, the technician, shared his expert knowledge and provided great service at a very reasonable price. I am a satisfied customer and will look into their maintenance programs for I expect to use Ralph's Heating & Air Conditioning for years to come.

Heating repairs were urgently needed. Ralph's Heating was happy to help, until they discovered the repairs weren't going to be covered by insurance. My impression is that the job proposal was "jacked up" in anticipation of a big payday. While I'm not certain of that, Ralph's Heating walked away from the job. I was left to believe that unless the company is able to get top dollar for their services, they simply walk away.

I moved into an older home that had been vacant in which the gas was shut off. This home had no Carbon Monoxide Detectors either. I Thank God every day that I called this company instead of just having the unit and gas turned back on. Upon inspection there was a crack in the heat exchange. I had no idea and I shudder at the thought of what could of happened to my son and I. The gentleman that serviced me was so thorough and explained everything and I felt like he truly cared. I'll never go without Carbon Monoxide Detectors. Ever! Thank you for putting up with all of my million and

I met a service man in my home parking lot. He was about to leave after finishing service for my next door. I approached him sitting inside service van and asked if he could see my heating furnace that seemed to be repaired.

He said he would charge $120.00 for trip charge. $120.00 TRIP CHARGE? What the heck? Trip charge is trip charge for coming to caller. He was about to charge $120.00 for tripping from in front of my home to inside, around 20 feet. Obviously, bad business!

I imagined how much this business would rip off people. This business deserves no star at all.
