Had a great experience with Allied. The first technician who came to check the system was very helpful. He looked at everything carefully and explained clearly that the AC unit needed replacement. After that, Chris L came for the estimate and explained the options in a simple and honest way. I felt comfortable with the process. Jackson S did the AC installation and he was excellent. He worked efficiently, was polite, and made sure the system was running well before he left. It is clear that the team cares about doing good work. I highly recommend them.

Another outstanding experience with Allied! After a duct cleaning company damaged our condenser coil and fried a control board, which the duct company tried to fix and only made more of a mess of, we asked Allied to come repair our system.

Craig came out the next day and at least gave us a functional furnace (vital as the temps were cold over the weekend), but we decided to replace the A/C as long as so much work was being done. So Matt came out the day after that and quoted us for the repairs and replacement of the A/C unit within an hour or so, including sussing out rebates available in combination with our furnace that they’d installed a few years ago.

Meanwhile, Maureen in Accounts Payable notified us that the financing terms offered by Carrier had changed between us accepting the quote and the installation date (only one business day), and as they were much more favorable, she took care of getting us the more beneficial financing.

Jason came out today and installed the new unit (heat pump, precisely), replaced the coil, fixed the duct work and plenum, and did other things to make sure that we were back to snuff. It looks amazing, he took care of our home and garden as if it was his own (including being mindful of closing the gate to keep our dog safe), and everything, heating and cooling, is running like a champ.

Everyone was wonderful, explaining what was what along the way, making recommendations, and being kind about the mess they were left to fix. As well, between Matt and Kevin, the service manager, we got all the detail needed to recoup costs from that duct cleaning company who started this in the first place.

Allied was responsive in our time of need and never took any advantage of the position we were in to gouge us, as other companies do to their customers. And best of all, we know from nine years of personal experience with Allied that they stand behind their work (not that it’s ever been a problem). Feeling relieved, happy, and well cared for.

I had a very frustrating experience with this company and would not recommend them.
Initially, I called them out because my heat wasn’t working. The technician was able to get the heat running again, but shortly after, my furnace started making an extremely loud noise that it never made before.
I had a second technician from the same company come out to diagnose the issue. He told me the noise was “normal” because I have a large furnace, and then suggested it was the blower motor. That didn’t sit right with me, especially since the noise only started after their first visit.
They came out again and continued to insist it was the blower motor, but couldn’t even guarantee that replacing it would fix the issue.
At that point, I decided to get a second opinion from another company. They took the time to properly inspect the system and found that the inducer motor had been physically damaged—likely from something being dropped during the initial service call.
So instead of just fixing my heat, this company appears to have caused additional damage and then misdiagnosed the problem multiple times.
Overall, this experience cost me extra time, stress, and money. I would strongly recommend getting a second opinion if you use this company.

I recently had my AC system replaced by Allied Air Conditioning and Heating Corp, and I couldn’t be happier with the entire experience. I worked with four different team members, and each one was exceptionally friendly, honest, and easy to work with.
Jeff was the first technician who came out to service my AC units. He clearly explained that one of my AC/heating units was on its last leg and walked me through the pros and cons of repairing versus replacing. Since repairs would cost around $800 and there was a chance the unit could fail again elsewhere, he recommended replacement — and I appreciated the transparency. That led me to request an estimate.
I then spoke with Matt at the office, who was great to work with. He helped arrange 0% financing for 12 months, provided a clear estimate, and kept me updated on delivery schedules and installation timing. His communication was excellent throughout the process.
On installation day, two installers — Jeff (a different Jeff) and Colin — arrived right on time, which I always value. They were professional, efficient, and did an outstanding job. They walked me through everything I needed to know about the new system, reviewed the checklist and invoice with me, and left the workspace spotless. Their attention to detail really stood out.
Thank you to everyone at Allied Air Conditioning and Heating Corp. I am a very happy customer and highly recommend their team.

Allied is a great company that has delivered great products, service and pricing/deals. They installed new furnace 23 years ago and I contacted them when it was time to replace the entire HVAC system. They gave me an awesome package price for great quality Carrier appliances. Everyone I’ve dealt with at Allied has been friendly, knowledgeable and supportive.
