Not only did Outstanding Heating & Cooling give us a better quote, but they did everything right. They set up an appointment right away, showed up promptly, answered all questions and concerns, installed the system in a timely manner, cleaned up after themselves, and did follow up calls to make sure everything was running smoothly. We couldn't be happier with OUTSTANDING HEATING & COOLING and our new efficient HVAC system. Thanks to Eddie Bennett for getting us set up with this new Bryant system and to the installers.

The annual service for my A/C was very thorough, and during the technician's visit, they checked…read morethe furnace and discovered a cracked heat exchanger that might have existed since the severe winter of 2025-26. I promptly arranged for repairs, as I occasionally use the furnace on cooler nights, even when daytime temperatures don't require it. Unfortunately, the first appointment was canceled at the last minute, and the second appointment couldn't be completed because the new heat exchanger arrived damaged, necessitating a reorder. Additionally, I was overcharged for cleaning the blower, which wasn't performed due to the heat exchanger issue. I'm still awaiting a refund and am uncertain about when the furnace repairs will be finished. This situation could have been managed more effectively, and I hope everything gets resolved soon. I will post an update when everything is completed as requested.

My wife and I are both in our sixties and contracted with Extreme Heating and Air in July to…read moreinstall a mini split system in our family room. My wife has asthma and other breathing issues as well as an aneurism. This unit was supposed to help alleviate her breathing issues on very hot and/or cold days. This has been nothing short of a fiasco. Minutes after the technician left, it began leaking water all over the floor. The tech 'forgot' to check the drain hose and had to come back out to repair it within hours. Only days later, we had to call them back out because it ceased to cool during one of the hottest days of the year. After sending multiple technicians, it was determined that all the coolant had leaked out because of an improper flange installation on the outside unit. The next issue was a faulty flange on the inside unit which, again, leaked coolant. After that repair, it still has failed to work, this time when we tried to heat the room during the recent cold spells. Same story, no coolant, only this time supposedly a manufacturing defect. After six months of this, I'm still waiting for some kind of resolution. After weeks of inquiries as to the status of the repairs/replacement, I can't get them to return my phone calls despite repeated promises to do so.

When I got home from work, the AC unit was still not working. I contacted them and the owner was at my house within 20 minutes. The problem was diagnosed and fixed. Upon packing up, he went and got the check my wife had written earlier in the day and told us because of the error, he was not charging us anything. We tried to argue that his time was valuable but he was hearing none of it and wouldn't accept anything for fixing our problem. I won't use anyone else from this point on.
