 Trustindex 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.

 Trustindex 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

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.

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.

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!

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.

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.

Freqently Asked Questions

What should I expect during an HVAC maintenance visit?

Our Chicago HVAC contractors will conduct a thorough inspection and carry out preventative maintenance work. They will also perform detailed HVAC troubleshooting to identify the causes of any existing issues. A maintenance visit is the most cost-effective way to avoid any issues from escalating.

Are HVAC services covered by warranties?

Yes. Many of our Chicago HVAC services are covered by warranties. For our labor work, you can get up to 10 years of warranty. It offers homeowners and business managers peace of mind knowing that they are fully protected against mishaps.

Discuss your HVAC needs with us for the most suitable warranty packages. Extended warranties are available.

How much does your service cost?

Every job is priced individually based on labor, system type, and scope. For example, installing one thermostat will cost less than installing multiple thermostats throughout the property.

And that’s why we promise to always offer a fair, upfront quote first. You will never be blindsided by a surprise bill.

Do you provide same-day HVAC repair in Chicago?

Of course, our Chicago HVAC contractors are always on call and ready to jump in. Contact us via phone or text message to tell us about your emergency. We can send someone out within an hour or up to 24 hours, depending on availability.

How often should I have my HVAC system serviced?

You should always service your system at least once a year. For commercial properties, you may even need bi-annual inspections.

Annual fine-tunings are not only vital in maintaining the system’s efficiency but also in extending the unit’s lifespan. A regularly serviced system will last significantly longer and be in better shape than unserviced units.

Are your HVAC technicians licensed and insured in Chicago?

Definitely. All our specialists are fully licensed and insured to carry out the appropriate HVAC work in the state. Only qualified experts are allowed to conduct most HVAC-related work.

Our certified appliance technicians are experienced and understand the Illinois climate well. They know the issues faced by homeowners and business owners. Every solution is tailored to your needs and budget.
