Excellent service--on time--reasonable pricing.Posted on Terrie SobeskiTrustindex verifies that the original source of the review is Google. George was professional and very nicePosted on Cheryl KennedyTrustindex verifies that the original source of the review is Google. Val was extremely professional and helpful. He was upfront with the total cost, came back same day with the needed parts, worked to find the best price for the parts saving me money, and made recommendations for future trade-in service on a humidifier. Will definitely use Astera services again and recommend them to other condo unit owners.Posted on Sam NelsonTrustindex verifies that the original source of the review is Google. Vlad was on time & great customer service.

Thank you for your feedback! We’re glad to hear that Vlad was on time and provided great customer service. We appreciate your support!Posted on John NapolitanoTrustindex verifies that the original source of the review is Google. I contacted Astera because I was not getting any heat in my baseboard heating system on the first floor of my home. Upon emailing them I received a response within the same day as well as numerous options for a in-home appointment and service. So they sent Steven who is one of the technicians for HVAC. Upon talking with him as well as inspecting the boiler in my basement he immediately came up with a plan. Steven spent a lot of time making sure I understood about what happened and why I was not getting any heat. He discussed with me what needed to be done and he made sure I understood. He completed all of the required work and I was very happy with the money that I spent for my total repair. This is the third time I have used Astera for issues in my home as well as my sister's home. I have been so happy with the service that I receive from Astera and will definitely continue to use them down the road. Thanks Steven John N Westchester

Astera was able to come look at our appliance a few hours after my initial outreach. The technicians were friendly, trustworthy, and repaired our SubZero with no problem. I recommend them without reservation!

EXCELLENT Based on 10 reviews Posted on J L.Verified Extremely quick responses with prompt scheduling; it was a great start to the job. Roman provided excellent and conscientious service - we would not hesitate to use Astera again.Posted on Ryan L.Verified I had both my washer and dryer serviced by Val. He walked me through everything he was working on and was finished up in about an hour. He was very knowledgeable with the specific models that I had. I would highly recommend!Posted on Rick J.Verified I read the Yelp reviews for Astera before I reached out to them, and the 5-star reviews are spot on! 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.Posted on David K.Verified This is my second experience with Astera and have only the highest praise for this business and the people that work there. From the person who answers the phone to the technician who comes out, everyone is friendly and polite. They're great with communication so you know when their techs are coming out. Our Sub-Zero fridge was throwing error codes which they diagnosed and repaired a faulty board. The work was done right and Alex explained everything afterwards. Highly recommend.Posted on L H.Verified Absolutely amazing company and employees! Rebuilt a brand new furnace installed by someone else, redid air intakes, humidifiers, disposal, broken freezer. Constant communication and always on time I'm so happy I found them! They even provided a rebate for taxes which the original installer wouldn't. 100% pleased, can't say enough good things about them!Posted on Peter P.Verified Repeat customer here and asked for Val M because he is great to work with. Clearly explains what needs to be done, very kind, and doesn't put pressure on you. Will continue to use Astera for their great service.Posted on Ellen L.Verified Val from Astera Heating, Cooling,and Appliance Repair was thorough, helpful,and he had great suggestions for regulating the heat in my home. The price was very reasonable as well for my yearly inspectionPosted on Liz S.Verified They were prompted on time kept me updated and did a very thorough job. I would highly recommend them.Posted on Diane D.Verified I recently had both the heat and hot water go out. I have an old boiler that needed several new parts but otherwise works fine. They recommended regular maintenance but unlike other HVAC companies don't try to sell you a new, much more expensive system. If you appreciate a company that will just fix your problem without upselling you, I would recommend Astera. The techs are friendly and knowledgeable. They talk you through the repair and answer any questions.Posted on Yvonne B.Verified found Astera Heating, Cooling and Appiances from a Google search. Their reviews were nothing but positive so I hired them to work on my boiler. The office staff was kind and professional. The service technician is extremely knowledgeable and did a thorough job on our repair. The interaction from start to finish was professional and efficient. I am adding my positive review to the reviews out on the internet. I would recommend this company for your Heating and Cooling needs.
