"Every other review on here is right on. First, Cesar is awesome. He called me back right away on a Sunday night (not expected) and was able to make time to see me the next day. He found a boiler (which I have heard is not very easy right now) and had it to my house for the end of the week. He had the old failing heater out and the new one installed (nice, clean install) in one day. Throughout the entire process he was very communicative. The crew wore masks in the house (as did we) when interacting with us which I appreciated and they were very careful to treat the house with care by putting down runners, taking off shoes, shoe covers, etc. Today (second day) they came back and are doing a final cleanup and reviewing any last minute issues. I screwed them up and caused an issue with a T-Stat and Cesar took the time to a. fix it and b. make sure I understood the right way to do it and how to configure it going forward. I really cannot recommend these guys enough. I am beyond impressed and feel very lucky that I found them for my boiler. The price was very reasonable especially considering the time frame they were able to turn it around in."

"We couldn't be happier with the service and product we received from this company! Mario was extremely helpful in advising us on what type of system would work best based on our needs, home, and resources; he was flexible and went above and beyond to help answer the many, many (MANY) questions we had. His team was very concientious and worked with us every step of the way. We now have a reliable, efficient, and even baseboard heating system and we're thrilled with the result! We'll definitely be calling Mario and his team again when we're ready to start planning for our cooling needs. :)"

"Sterling Heating & Cooling saved the day! Our heat went out, and my husband has a number of medical conditions and cannot tolerate being too cold. Sterling came promptly and they were able to identify and repair the issue within an hour. They were pleasant and customer focused. I would highly recommend Sterling Heating & Cooling!"
