The tech was courteous and explained what went wrong and how he fixed it. He also noted our unit is on its last legs but did not go into any hard sell.

I have to say, I'll probably go with JML when we do decide to replace it just off of the professionalism they demonstrated.

I sent a message via Yelp on a Sunday night and they immediately scheduled our oven troubleshooting for Monday afternoon. Their front office staff is incredibly responsive! George (technician) arrived timely and was very thorough. He explained things to me every step of the way. He is approaching this very methodically - ok, so it's not the igniter, let's look at the next link in the chain... I saw George called out by name in other Yelp reviews, and I understand why he comes so highly recommended! He called the manufacturer to discuss his findings, but the manufacturer tech team wasn't available. He let me know he would be calling them again in the morning and that he would reach out to me with an update. I've had plenty of negative or so-so experiences with other service technicians from other companies. This experience with George / Astera is so positive that I'm posting my review even before the service is completed. Astera will be getting first crack at all of my appliance and HVAC service calls going forward.

It turned out my AC unit needed a new compressor and more freon because it wasn't cooling enough and too much ice was building up on the coils in my home thus causing a leak when the ice melted. Andrew also saw that the drain tube coming from the unit inside was clogged. He cleaned the tube and got everything working properly again. He also recommended using less restrictive filters for my system, stating that the higher quality ones are too restrictive and don't allow for efficient air flow thus making the unit work too hard. All of his recommendations are paying off since my system is no longer leaking and is working much better than before. I'm grateful for his knowledge and expertise. He's honest and has fair pricing. I've referred him to many of my neighbors.

The impressive part was the quick response from Vlad who is the owner and a technician. He was able to send someone the next day. The person figured it out and got it fixed. However, something was off on the repair which I noticed and Vlad again quickly came out to correct it. These days it's hard to get the type of attention and response from most businesses. Also things inevitably go wrong and you want to make sure you can trust a business to correct any issues. They do both very well!

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!

See pics I file a dispute with thumbtack and still waiting! Update as of today 1/20 I spoke to Alex the manager of duct professor and that he supposed to get me a refund for the scams that his techs did back then but, never happened. He is upset about my reviews and won't refund me any money because I left bad review. It doesn't work this way Alex. I want more people to be aware the way that you and your techs provide services. I was a part of your scam but not let that happens for other people. Even if you tried to offer me to give you a 2nd chance for cleaning but I am not TRUSTING you at all. You should do the job correctly at the 1st time. I was lucky that I found out after I replaced my furance. Also, the three kids that you sent me to do the job let them be more professional when they get into people property by wearing the shoes cover to have some respect for the people that lives in the house. Also, order them a good flash light instead of using their phone as flash light! what a scam? Please be present at the time of service don't be victim like me. Also, make sure to check the filter and the return duct base after few days of cleaning to see if any debris left over from cleaning I am not able to upload photos after the service was provided by duct professor crew.

DO NOT HIRE THIS COMPANY! Updating my review after things just got worse. These guys are scammers,…read morethey will overcharge for their diagnostic visit and they will tell you that your furnace needs costly repairs when it does not. I recently called them to look at my furnace because it was not kicking on. The tech walked in and said immediately, "I know by the sound what the problem is". He took off the cover of the furnace, checked it out and told me that my inducer motor was broken and that I needed a new one. He wrote up my "diagnostic" charges, totaling $137.00 and tried to get me to schedule the motor replacement for the next day, at a charge of $675. He was at my house a total of 10 minutes. After he left, I looked at my receipt and saw that I was charged a $90 diagnostic fee for the first 15 minutes, $35 for an additional 15 minutes of labor, and $10 for parking. Again, he was only here for 10 minutes. That was all bad enough and a total scam, but whatever, not a huge dollar amount. I did some research and decided to get a second opinion on the inducer motor. I hired Siberia Appliance Repair (I would highly recommend), and Val came out to look at my furnace. I learned that there is absolutely nothing wrong with my furnace and NOTHING wrong with my inducer motor. It simply needed to be manually spun ONCE after sitting all summer. Perfect Temperature Control are liars, scammers and thieves. If you want a Company to waste your time and steal your money, you should hire them.
