Because of that experience, I was really dreading having to call someone when the air conditioning went out in my current home. I spent a lot of time reading Yelp reviews for numerous companies before finally deciding on Astera. From the very first phone call through the completion of the repair, I couldn't have been more impressed. The entire experience was professional, honest, and stress-free. The team was responsive, knowledgeable, and took the time to explain everything clearly. After my previous experience, finding a company I could trust was incredibly important, and Astera exceeded my expectations. I highly recommend them and would not hesitate to use them again. Five stars simply aren't enough

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.

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.

The "free" vent cleaning caused dust to blow all over my condo unit. Not good when you have lung disease. I ended up cleaning dust that had been trapped in the vents. The tech didn't bring a shop vacuum to take care of. the job. They used a machine that flapped a rag around in my vents. I was concerned that the vents would be torn up. The motor itself is very loud and I still haven't gotten used to it. The contactor slams in and start up is a continual disturbance. Noted too that there are no insulators around the main electrical breaker. Decided to pass on the "free warranty." The associated service calls required to maintain the warranty were not "free."

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.
