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.

Then decided to tell me that they are running behind. Could not give me an update to when. 1:54pm still nothing. Had to call Home Depot and ask what is going on. 2:59pm at my house with no heads up. Upset that no one is home now. Finally called me and I told them I will be back in 30 mins. They came inside and tried to tell me I needed all of these things. Told them I didn't need them and they said then we can't do the install. Ask the guy to leave and he did. The best part was he said it would take 6 hours to do the job and drain the old tank. Now I know why they are behind.
