Allied Air Conditioning & Heating Corporation - Palatine

I'm very happy with Allied, they had the best pricing between other companies like Shavitz and AA Service. $1000 - 2800 less installing the carrier line. Even though they were only a few hundred more than cheapest competitors they provided a 3 yr warranty on labor compared to the 1 year from others. I was deciding between companies that had no less than a 4 star rating on reviews so I was confident that installation would be done professionally. Patrick was my sales engineer and knowledgeable to answer my questions about comparable products.

I had Allied come out for seasonal maintenance on my furnaces. The technician told me that the heat exchanger was cracker on both furnaces. They were only 12 years old and seemed odd that both furnace heat exchangers cracked in the same year. He also told me they weren’t covered by warranty because I wasn’t the original owner, which turned out to be false. I asked for option to replace heat exchanger or furnace. Allied sent their sales guy out who only quoted me new furnace for $7,200 each furnace. Never sent me quote for heat exchanger replacement. I had another HVAC company come out they confirmed the heat exchangers were under warranty and could replace them for $1,800 each or replace the furnaces for $5,500 ea but after they inspected the furnaces they found that neither heat exchanger was cracked or emitting any CO2. Allied was very dishonest and will never use them again.

They staff at Allied is so courteous, professional, and especially patient with my homeowner curiosity and endless questions.. - Installers Jeff and Francisco did a great job on a recent furnace install, and Matt continued to answer questions after the install was done. Thanks Team Allied....

i have used allied for a long time and have always been satisfied with the service i get. today 11/7/22 i got a new furnace installed by Sam who was very friendly, helpful and professional. thanks also to Chris too. i will continue to use allied forever.

They have been helpful throughout the years, dealing with the challenges of an old furnace that couldn't handle an addition from a previous owner, to installing a new furnace and AC properly sized for the house along with the challenges of a proper exhaust system.

In no particular order, thank you Chris, Kyle and Jeff!

Allied (Matt & Jeff) advised and installed return vents in my basement. The air in the basement was not smelling good and I wanted an Air Exchange. Matt explained that the air exchange wasn't necessary and just using return vents should work and will cost a whole lot less. Jeff installed the vents. He was on-time and extremely professional and completed the work really well.

Very happy with the service. I will be using allied for all my HVAC needs.

Earlier this week my heat went out. As I believed my furnace was warrantied as it clearly states on Allied sticker, I contacted them in the morning. Their only available time to come out was 5 pm that day. When the technician Steve arrived, I explained that the unit tripped the circuit breaker twice and that the inducer was making a noise. I then said to him that I had contacted them because of the fore mentioned warranty clearly on the furnace. Only after he had opened it and begun taking parts out did he then mention to me that that warranty would not be honored because I was not the original purchaser. I said that seemed to be a bit misleading, to which he said if I had an issue o could call the shop and they would tell me the same. And then he said something to the effect that well you need heat. After looking over the unit for a minute or two and taking out the inducer, which I had mentioned was making noise, he found that it did in fact arc in my unit. He then told me he would run out to the van and see if he had a spare part. As he did I found a replacement part online from supplyhouse.com for approximately $220. When Steve returned he said he had the part and that he might be able to safe a component of the original, which could save $70. (Mind you the entire assembly kit was $220 online). He then quoted me something in the realm of 500-600 for the part he did have as well as additional labor and installation. I understand the reality of marking up parts, but to the tune of 100% seems a bit much. At this point, about 15 minutes into his “diagnosis” I said I would purchase myself because he seemed to not want to made any price changes. He then made a comment about how I could buy online, but how would I install it. I told him I was capable and that I wouldn’t have called if I knew they didn’t honor the warranty (Mind you the part was held on by three screws and had a quick connect). I then took out my check book and asked him what the damage was. He did not respond to that, (perhaps he didn’t hear) but I held the checkbook in hand. He then said he’d reattach the inducer, but left the switch off that mounts in front so that I could install the part when I got it. He put the unit back together and left wishing me well on the way out. I thought it was an ok interaction and that this company at-least did me a solid for not honoring their work warranty. Low and behold Two days later I received this bill in the mail. I don’t know if this is par for the course with this organization, as they seem to get good reviews, but I was not impressed by them this go around. Furthermore, if a part arcs in my unit that is only 5 years old seems like poor quality on both the part of the manufacturer and installer. The bill does not match the quality and level of service or lack there of.

Allied replaced my furnace in 2019 and my A/C unit this year. The Carrier products they sell are great, but I'm loyal because of the quality of the work and the customer service. Billy installed both my systems and he is an artist with a small utility closet. I know it's weird I'm so proud of my utility closet, but there it is. Billy somehow fit a whole new furnace/humidifier system in the small space so seamlessly, I'd totally believe it if he had a secret life as an interior designer. That's why I had to have him for my A/C install. He has this attention to detail that focuses not only on how the system needs to work, but how we actually live - going so far as to fix the line to the side of the house so my husband will stop hitting it with the weedwhacker. I highly recommend Billy for any install. And if you need service, Octavio is your man. Going above and beyond, being friendly and attentive, showing up on time, and shooting straight with what you need and what you don't...these are the reasons I stick with Allied.

Allied was professional, and communicated throughout the install of our new furnace. I would highly recommend them!

Had an AC unit its last leg. They came out and did a short term repair while they got the parts to replace my existing AC unit. They were competitive in their pricing, they took their time, did the job right, were very clean, and respectful. Would trust them to do more work on my home in the future.
