Ed is the best! He gave us a great deal on a new A/C, did the entire install himself, hauled the…read moreold A/C away and even cleaned out our furnace. He's been doing this work forever, and it shows. I can't recommend him enough, he really made this far more reasonable for us and came out just two days after we called him. We will certainly be using him again in the future. I also enjoyed his stories and he's a cool dude. Inga

I had an issue with my heater in one of the coldest days in Chicago and as always we called Ed and…read morehe promptly came and fixed it. Great experience and I will continue to use his services!! Reliable and friendly service!!!

First off let me start by saying Andy is truly a life saver…read more Over night the blower motor in our furnace went out and smoke started coming through the vents. The fire department was called and we (me, my wife, and our 3 kids) were without heat on a 20 degree night. The following morning I made a few inquiries just hoping to get something scheduled and I was surprised to find they had someone available almost immediately. The estimate fee (only $75) was waived once Andy informed us what we needed, 1 hour later our house went from 65 degrees to a comfortable 74. Thank you so much. I would HIGHLY RECOMMEND them.

Our furnace shut down on one of the coldest days in December and Andy responded quickly to the…read moreservice call. Andy did a great job at figuring out what was going on with our furnace, explained the options to fix what was needed, and did the repairs that were necessary. By also figuring out that the gas meter was the issue that needed to be taken care by our gas service provider, Andy saved us so much money on unnecessary repairs because the initial issue was outside the furnace. This is the second time we've used Specific HVAC and I will continue to call them for any future repairs. Andy is friendly and provides quality service.

Mark came out on a holiday weekend as our AC was not cooling. He was able to quickly diagnose the…read moreproblem and repair it on the spot. Mark walked me through every step of what he was doing, and within a half an hour our AC was pumping out cold air again. I would HIGHLY recommend Collins to anyone. They truly want to help their customers and not just sell unneeded items. Easily a 5 star company!

My furnace stopped working and cold temperatures were starting to come in.. after looking up a few…read moreheating places and seeing reviews I chose Collins. I'm so glad I did. Mark the owner is honest and friendly. I felt confident in the opinion he gave me and would trust him again in the future. I'm enjoying my new furnace and humidifier without worries for the winter. Give him a try, you won't regret it!!

Only company I want touching my plumbing and heating. My parents have been customers of H&N for…read moreyears and I followed suit when I purchased my home. They are honest, affordable and do great work. Finding honest places that don't try to sell you something you don't need or won't fix the problem are hard to find. Sometimes there is a bit of a wait, but they're worth it. And if you have an emergency, they are right there to help you out quickly. Nice family-owned business with integrity.

The day before the recent holiday weekend, our 8-year-old air conditioner decided to stop working…read more We immediately called the company that installed our HVAC system and had been handling its maintenance. Instead of speaking with someone, we were directed to a text system that assured us a technician would get back to us "shortly." More than nine hours later, we still hadn't heard a word. Our son, who has been a homeowner for a few years, recommended we call Zark. I'm so glad he did! When I called, Rob, the owner, said he was just grabbing a cup of coffee and would head over right afterward. True to his word, he arrived quickly. Rob confirmed the issue my husband suspected, replaced the faulty part, and had our air conditioner running again in no time. He also offered us a discount on the repair when we signed up for their routine maintenance plan--which is actually $50 less than what we had been paying the company that installed our system. Rob was honest, responsive, knowledgeable, and fair. It's refreshing to find a business that truly takes care of its customers, especially when you're dealing with an unexpected problem before a holiday weekend. Zark has definitely earned our trust, and they have gained loyal customers. We truly value businesses that stand behind their service and can be counted on when it matters most. Highly recommend!

These guys are the best! So I come home from work during one of those freaky end of summer weeks…read more(temperatures were in the 90's) and discover my house is 10 degrees warmer than the temperature outside. My AC was blowing warm air and my husband was at work. I researched mailers, yelp reviews, and called a couple of heating and air conditioning services. I'm calling the advertised after 24 hour emergency phone lines and leaving messages with no reply. Finally, Windy City Mechanical answers the phone and inform me they could send someone out. Luckily, the guy lives right around the corner and is there in minutes. He walks up introduce himself and proceeds to inspect my AC unit. We go in the house and he informs me of the options available. He sat in my house for an hour sweating bullets with no complaint or discomfort answering all my questions and my husband's via phone. My husband and I decided to replace the entire AC unit for various reasons including the age of the unit. Tom educated me on our options and explained the units fairly and without bias towards a more expensive unit. As a matter of fact, he determined we didn't need the larger unit we currently had and a smaller (less expensive) unit would suffice. Nevertheless, his guys were there the next morning to replace our AC unit. They were prompt, professional, and efficient. I would highly recommend Windy City Mechanical they gave us a great deal!

In response to Tom - You are right in saying I was upset…read more And as I previously stated, the ejector pipe might have only lasted a few days ... but then again, it might have lasted years. When I asked what Windy City was going to do about it, you said nothing. That's when I got upset. And why on earth would I take any of your calls AFTER you had said your company was going to do NOTHING. This conversation is over. You and your company have a long way to go with customer service. Yelp is for reviews. I reviewed. I would not recommend your company. It's up to the reader of this review to make an educated decision based on the facts.

Since then I have called them again since my hot water tank went out and they came later that day, since they knew how stressed and upset I was! Fixed it in only about an hour or so.
