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.
