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.

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.

Knowing I had no choice and needing a replacement during the winter months, they gave me an estimate which was extremely over priced for a Goodman furnace and ac, and they wanted 80% down payment, no financing, then when I told them that I'm going to look around for comparison they got extremely defensive and tried to say other companies were no good. Back to the real PROS, EcoAir was referred by a family member and could not be more thankful with the top notch work they did from the start to end. Called them and Diego (the owner) is extremely patient, professional, and honest. He answered all my questions and I felt no pressure to purchase anything from them. They are exclusively with Rheem brands, 10 year parts and labor with maintenance plan. He gave me 2 different makes and models so I can compare price and efficiency. Prices were reasonable and under 10K (AC and Furnace) for the size of my house, they also offer financing. When he sent one of his techs (Ruben) for an estimate, he came fully masked and wore shoe coverings. The whole process took about a week, mainly it was myself who took long because I was doing my research and making sure I had the budget for this unexpected major expense. On their part realistically took 2 days, the other techs (Ivan and Marco) were also fully masked and with shoe coverings anytime they had to come inside the house, my furnace was installed in the attic but to enter the attic was from the side of the house. They were also very careful in removing the boiler and pipes, very respectful not to ruin the walls or floors. Only delay was looking for a licensed plumber to run a gas pipe installation to the attic which was very difficult during the week of rain and snow. Eventually, Diego and his team of techs (Ruben, Ivan, Marco) helped me and our family get some much needed heat! Also want to add, that they send you text reminders of your appt and when the techs are on their way, and they were on time every time. I don't wish anyone to have their heat break down during the winter months but when the unexpected happens, I guarantee this company will help you!

You will also be charged for travel time to your destination. You will have a large repair bill by the time his visit is over. He uses a program on his computer with pre-programmed labor rates for absolutely everything. As a one man operation I would think he would work much faster than he does, but he is actually quite slow. And to top it off, if you ask him to explain the various charges, he develops an attitude. Buyer beware.

I just wanted to express my gratitude to your company in general (21 year customer) and to Marvin…read moreD. in particular for the prompt response to the "chirping" noise in my vents after my new furnace installation last September. It took multiple "tinkerings" to resolve the problem. What I really appreciated was that as soon as I called, Marvin adjusted his next day's schedule and came out to my home and worked several hours, not leaving until he had thoroughly tested and verified that the problem was resolved. No vague promises of "I will see when I can get to it", he arrived the next morning and stayed until the problem was resolved. BTW I was very impressed by Marvin's HVAC knowledge, as well as his patient and friendly attitude while working in my home. Thanks!

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!

They sent a proposal for $865 just to replace two cartridges that cost $30. I found someone else instead to get it done for $229. And when their AI sent me a nudge about the proposal and I sent an update that I already took care of it, I got a response - "Thank you for your time. Unfortunately, we don't service your area."

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!
