No issues with the technician would did spend a bit of time taking the oven apart. He tested the control board and said it was the issue, collected my service fee, then an hour later sent an estimate for more than the price I paid for the oven two years ago. 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.

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!

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.

The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me.

Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested.

Jesus performed extensive testing on the units, which was much more detailed than what I was used to with Four Seasons. He found a faulty capacitor, showed me the readings, and explained everything clearly. I even double-checked the process on YouTube, and everything he said and did checked out. Overall, he's honest, hardworking, and provides top-notch service. Highly recommended!
