Full System Replacement
July 10, 2025
Crew arrived at 7:30am and completed by 1pm. They had to do additional work to get the return and air handler placed. Did a great job. The guys insisted they clean up the footprints throughout the area they walked even after I told them I can handle it. Would highly recommend.

Extremely pleased with Astro Heating and Cooling. Called for quote to replace HVAC, came same day with proposal. Pricing was fair, discussed several options. They were able to install the new system the next day and took care of registering my Carrier warranty. The crew and the office staff were friendly and efficient. I highly recommend this company.

Great experience despite supply chain mishap
May 24, 2022
Service was great... Carrier did send out a unit that lacked capacitors in it, but Astro expeditiously found the parts and my unit was operational within 48 hours of start of installation. Joe the salesperson was very understanding of my needs and guided me to purchasing the correct unit for my needs. Went through pros and cons of each unit and did not pressure me to purchase one over another.

5 STAR Service!!!
April 12, 2022
Well I can start off by saying a massive thank you to Astro for a 5 star service. Thanks to Joe who sat down with us and In great detail went through all that Astro has to offer as a company that fits around any budget, plus giving us peace of mind on our investment. Joe was upfront and honest, and gave us all our options without pushing us to make a decision. As new homeowners we were in a situation to replace the existing HVAC because of age and lack of maintenance by previous owners, but now we have the confidence in our new system plus the guaranteed warranty provided we are delighted! The guys who fitted our new HVAC system were polite, knowledgeable, responsible with our property and above all else professional. We highly recommend this company for any HVAC installation/repairs and we will continue to use Astro as our point of call in the future. Thanks

Jason and his crew responded quickly to our call. Within the day they measured for a new unit and had an estimate to us with consideration to our needs. Within the next 12\-24 hours they had our new system installed. They were on\-time and even helped assist with moving some items in our home out of the way to install the system.

Still waiting on my Humidifier to be installed
June 27, 2020
The whole experience was very good. The sales man, the repair team was on time, very efficient, cleaned up and did a thorough job of explaining the new system. I am still waiting on my humidifier to be installed. They also had to cut a hole in my siding \& I had requested 2 second look to be sure it was water tight I'm still waiting for that response.
