Lex went above and beyond. Our heater was shutting off exactly after 7 minutes, and we were initially told it was a thermostat or wiring issue. Lex took the time to properly diagnose the problem and found the real cause: an oversized HVAC system that was overheating and shutting itself off. He adjusted the system pressure to bring it within the required range, which was especially important since the unit is located in a closet. Lex was patient, transparent, and clearly knew what he was doing. The issue is finally resolved, and I would specifically ask for Lex again without hesitation.

Wow, they know their stuff! They got high ratings for a reason! Lex and Vlad did an amazing job bleading my boiler heating system.

Responsive company, but be cautious with their diagnosis and pricing. My 12 year old Rheem furnace wasn't producing heat, and the technician concluded it needed both a control board AND a gas valve, quoting $1,200 ($275 parts, $925 labor for a ~2 hour job). I was skeptical, so I got a second opinion from another reputable company. Their diagnosis: only the gas valve needed replacing, which they confirmed by tracing the 24V signal through the ignition sequence. Total cost with them: $500, less than half of Astera's quote, and for the correct repair. I'll give credit where it's due. Their $65 diagnostic fee is genuinely fair and I'm glad they're keeping it. But that's where the good value ends. A $925 labor charge for a two hour job, on top of a misdiagnosis, is hard to overlook. The pricing system overall is just out of whack. On top of that, their quoting process is unorthodox. The initial quote was simply $1,200 tied to two parts with zero breakdown of labor vs. parts. I had to specifically ask in order to get a clear understanding of what I was actually paying for. That lack of transparency upfront is a problem. Astera may be responsive and have great reviews, but I'd strongly recommend getting multiple bids before committing. An inflated or inaccurate diagnosis can cost you big.

I had Astera come out to diagnose what was wrong with my washing machine. They made it very clear that there would be a diagnostic fee, which I was completely OK with. My issue was that Vlad, the tech they sent, was at my residence for less than 5 minutes. He accurately diagnosed that my washing machine was semi-broken (which I knew), and told me specifically that the rear bearing was broken and the outer tube and rear inner bearing need to be replaced. He recommended that I just buy a new machine. I wasn't quoted repair costs, or given an estimate of repairs, just told it was broken, and to go buy a new one... I understand that may be the professional opinion, but it's not professional to spend less than 5 minutes at a house call, collect a diagnostic fee, and leave. It left me with the impression that they just came to collect the fee.

Excellent Service from Astera ? Highly Recommended! I recently had my old AC unit repaired by Astera, and I couldn?t be happier with the service! From start to finish, Steve was professional, knowledgeable, and efficient. The technician arrived on time, quickly diagnosed the issue, and explained everything clearly before starting the repair. Despite my AC being quite old, they managed to fix it perfectly, making it run like new again. Their pricing was fair, and they didn?t try to upsell unnecessary services. I truly appreciate their honesty and expertise. If you?re looking for a reliable AC repair service, Astera is the best choice! I will definitely be using them again in the future. Thank you, Astera!

On the coldest day of the year, my furnace, as expected, decided to stop working. Having just bought my home, I was faced with a tough decision?repair the old system or invest in a new one with a 10-year warranty. After speaking with Astera Heating, Cooling & Appliance Repair, I knew I was in good hands. From the very first call, Valentina was incredibly sweet and quickly scheduled an appointment for the same day. Steve arrived promptly, diagnosed the issue, and found that the motor needed replacement. After discussing options, I decided to go with a full furnace replacement instead. The very next day, Steve and Yuriy arrived and installed a brand-new system in just four hours! Now, my home is warm again, and my new furnace is incredibly quiet compared to the old, noisy one. I couldn?t be happier with the fast, professional, and high-quality service that Astera provided. If anything happens in the future with my AC or appliances, I won?t hesitate to call them again.
