Superior name doesn't lie: the company delivered superior service during the heating emergency we…read morehave experienced. The things I appreciated most is the speed of the service during the cold spell that prolly spread their crew quite thin and excellent communication. Why is the proper communication so important: When anything fails in your home you are often at loss and quite confused... it was reassuring to have Mike describe what he was seeing as he inspected our AC! It was equally great for Paul to tell us specific steps they were to take and stick to the self appointed time line! It not only reassures the homeowner; it can help us plan around the emergency. Knowing that Superior is a local company is another plus: you know their crew works in the area, probably can quickly utilize local team/stores that offer parts. You obviously can guess that I am writing this review from a very warm house where an AC motor is going strong!

Last March I had a Champion whole home generator installed.

They also came back 4 months later and did an oil change on the system. customer service was top notch. The best part? GSHA beat the price quote from B Electric in Skokie by 40%. If you're thinking about a generator this is who you want to contact.

On the last week we had to get the project done, we were ghosted.

They were able to fix the problem with minimal expense and trouble. This is during the pandemic and the crew members were appropriately dressed with PPE and had minimal "contact" with us. They are very respectful of what they are doing in your house, explain what they are doing before they do it so there are no surprises when you get the bill. They are also highly skilled and do not try like some others to do extra work that is not necessary. I trust them totally. Highly recommend them.

Would be great if they emailed the invoice so the turn around could be do-able. Wish I got paid in 20 days of service! And they are expensive - 168 an hour - with 160 for the first 30 minutes.

I said what about a space pac type system. They said that would be more cost effective and quoted it at about $30K. I thought this was way out of line for the work and it felt like they just thought I wasn't going to get other quotes since I had been using them for so long. But I did, and after a bunch of quotes I went with Ireland Air, Couldn't have been happier. They were the lowest but they we a third less and seemed much more knowledgeable!

The boss, David Ireland, has been to my house to evaluate a difficult problem. It took him 15 seconds to find my problem and eventually put in a new air conditioner for me. He explains things clearly and is very experienced, very patient, and an all around pleasure. Then I had a problem which no one could solve for 3 months. A terrible blowing and buzzing noise throughout the house. It was making me crazy. Kyle, the wonderful guy in the office who schedules and does many other things, sent me a younger technician, JOE, who got right to work. He admitted that the noise was way too loud and not normal, and was the only person I had had thus far who thought the furnace/AC was working properly. He went through the whole unit very systematically and shortly explained what he thought was wrong. He proposed I order a part, went right then and bought one, installed it, and presto! - there was no more buzzing! This young man was professional, persistent, patient, and a delight to interact with. For me today, Joe was worth his weight in gold and took a major problem off my bucket list! .......But there's more - he found an issue with my office air/heat unit, changed batteries in related equipment that no one had done before, cleaned rust off the outside unit - which was a first, didn't suggest we replace the unit which is pretty old but thought a replacement part would serve us well for a time. Joe cares about his customers and their money, and is very careful not to err. I watched everything he did and was very impressed - and I'm pretty fussy about workmen! If you have what you think is a unsolvable problem, call and ask for Joe to show up on your doorstep! He even suggested we get new carbon monoxide detectors and tole us where to put them. He looked at our situation and equipment in a wholistic way and didn't miss a trick. L Weiss
