His prices are very affordable so, if your A/C Unit went out and you think you can't afford a new unit...look no more. Nothing beats a call. I am an actual customer and I'm satisfied.

I would never recommend this guy to anyone. First off he is not reliable. Sets appointments and did…read morenot show up or call to say he cannot make it. This went on for 3 months. The second issue is he gave me an estimate of $750 to clean my 9-year-old boiler. Since he would never show up, I called Chicagoland heating. They came in and totally cleaned the boiler for $165. Since then, I have run into others he has serviced. Was told his ploy is to convince people they need a new replacement and they did not need one. Beware

I contacted them during a rainstorm on a Sunday, and Jim came out at noon Monday. (The water…read moreheater manufacturer's website gave me his contact info, since he is authorized to service them.) Jim is extremely knowledgeable about water heaters and fixed our problem in a half an hour for a reasonable rate, even though others I contacted wanted to replace our water heater. I would use him to install my next water heater, but he no longer does that .

Initially was told the owner was the only one who could give an estimate. Had to wait just to schedule. Two days later I got the appointment for the estimate. On the morning of the estimate I get a text approximately 40 mins before the estimate saying the appointment needed to be cancelled and they would call the following week to reschedule.....and they never did. Another local company got the business. If they can't complete something as simple as an estimate, I wouldn't trust to do the work.

The follow-up was good although they always seem to say "this is just a bandaid.. there will likely be additional trouble in the future". It makes me feel like they don't complete the job, hoping they'll get called back to charge another $720. THE PRICE WAS RIDICULOUS. Did I mention that the price was ridiculous? Be prepared.

It was a simple fix had Cilff came back & took a look at the area. Which by the way his young sons installed the water heater. I should have been watching myself!!! So I had to pay $125.00 for a heating company to show me the cause. The door was pushed up, I believe by accident. This is my last call to Drain pros. I will use a different company.
