Hero Air is great as far as I can tell. I mean it seems like nothing comes cheap but they at least…read moreseem fair. I will copy the review I wrote about ABC, which lead me to hiring Hero Air in the first place to give you the full picture: Update: ABC did show up at 8pm the following night and proceeded to quote me $1,363 to replace some components and $475 to deep clean the condenser coil. I was paying for their VIP service and that is the quote I got. I said no way since I trust them zero. Got Hero Air, who get amazing reviews on Yelp to come out and were there within 2 hours. Turns out I needed a new thermostat, which all in for diagnosing, running out to get the thermostat, and installing for $407. He also recommended a deep cleaning and charged me $150, so for $557 instead of $1,833 which wouldn't have even fixed the problem I am up and running 4 hours after requesting an appointment. So when I said above they hope idiots will let them get away with charging triple, I was not exaggerating. ABC deserves to go out of business. It seems like with their AI reservation system and "fluid" scheduling they probably go bought out by private equity and it seems like they are running themselves into the ground. DO NOT USE THEM FOR ANYTHING!

I can look at the part online and they are wanting to charge double, plus $500 for roughly the same labor that they just spent doing for a $65 service fee. So while they were quick to respond and nice enough... I'm still up a creek with less money and more wasted time.

Fan burnt out and need replacement. Warranty expired over one year. However they gave us a discounted price for a replacement. Also needed a new thermostat and probably the cause for the fan to overheat due to a relay issue. Due to our time constraints, Troy couldn't do the job and made arrangements for today. Troy came over after 3 pm ( 2-4 pm window service ) and did a quick and good job on the agreed work. Paid $662 for the total amount. Explained the mechanism for the new thermostat and advised to call them back for any issues with the new fan and thermostat.

So, that seemed a little outrageous. Contacted nick and from the onset knew that this would be a different experience. Let the glazing begin! Cannot say enough about nick and the business that he runs. Was a pleasure to work with him diagnosing the issue (he took a look at the photo l, asked me to retrieve the model number on the stove/griddle and saved me that absurd 210 fee) - gave me variable pricing between generic and OEM parts, and was quick to schedule service rather than having a lead time of weeks out like the other companies were requesting. On top of that, he went out of his way to take a look at my dishwasher as a courtesy as it was giving us an error just before he left our home. People like nick remind me that there remain honest and hard-working service people out there. Super glad that I found his company and would not hesitate to have him out again to perform any repair as needed. Thanks again, nick!

Update on July 17, 2026. It is nice of the owner, Mr James…read moreCox, to reply... James: your tech came and all he did (besides his constant: "call my office for a new unit") was spraying (my) water on my 2.5T Trane... THIS IS NOT "MAINTENANCE"... To say: "your system is on borrowed time to say the least and extremely inefficient the older it gets." is immature. the unit works FINE, is very efficient, as I write it. I am a seasoned Senior Design Engineer (has one USA patent granted) and know "something" about "something". I design things for all to use them and for some to service them. 2.5T for a small house like mine is possibly an overkill but that explains its lasting. 40 years of working AC unit is unheard of, correct, but it is ME who decides about replacement or maintenance, and your tech (still working there?) did NOT do the maintenance I've paid for. So, he did no technical work and you owe me that 99(?) bucks :-)

AC died in the middle of the night. They came out the next morning and said my unit was too old…read morerepair (just over 20 years old), while ripping out something from the power box and seemingly breaking a component in there. They said they could try to do a repair for about $1.3k but that they couldn't guarantee the repair would be effective because of the condenser. They then tried to sell me on their highest end heat-pump for about $24k, which was too much for our needs, since our furnace was also functional. We ended up choosing a basic AC replacement for around $9k. They were able to install the new unit two days later. However, on the day of the install, they saw some surface level rust on the furnace heat exchanger and tried to get me to replace it for an additional $4k. When I said no, they backed off and recommended a CO alarm (which we already have). It felt like I was being heavily taken advantage of because I was in a dire situation. The installation went fine, but my experience of being pressured and hard sold to during the process made it feel like I was being milked for every penny they could get out of me. Take this as a precaution to check your HVAC AC/furnace/heat pump regularly, and get multiple quotes before deciding on work. If you go with this company, they will seemingly do an effective job, but they will try their best to get as much money out of you as possible.

Tried to tune the furnace anyway to accommodate it, which was actually kind of fun to watch all the different ways it could be done. No other HVAC technician I've ever worked with before has done that. A/C maintenance went great too. First company I've ever hired that didn't try to sell me an entirely new unit just due to a faulty capacitor. Even gave me the model number of the capacitor to replace if I want to save money and do it myself (I'm reasonably handy so it's something I'd probably do). I'll be using them for as long as they give great service!
