I have been going from one electric company to another for the past 4 years. It has not been a good experience. Then I found Service Heroes and I am beyond happy! I had an entire central air system put in replacing the old system I had. This company is the BEST! They were very customer friendly, which is hard to find in these days, and very knowledgeable, polite, and on time. When the work was completed the room and the outside was spotless! Joseph did all the work and he is awesome. The owner is Justin and he is amazing. Service Heroes is going to be the ONLY electric company I ever call again. I will recommend them to everyone! And did I say, the price was spot on great!

Justin is a hero! He spent 3 hours servicing my entire system for $70! Justin is communicative, honest, knowledgeable and hard working. He identified a potential issue with my blower which ended up being the result of a previous bad service. They tried to oil sealed beating which doesn't work. Justin let me blow and clean the blower mirror assembly which made it run like new. He also measured and identified an off limit capacitor which I replace myself from Amazon for $10. Justin also cleaned up my AC outside unit and checked the caps there. My system is now checked, cleaned and running like new thanks to these guys. I highly recommend them. Just make sure you do your homework and take your time to understand if there are truly any potential issues that need fixing especially if your units are on the older side. I opted out of the coil cleaning service as it is too expensive and not worth in my opinion. All and all, great guy.

I recently had a new Goodman AC system installed by Service Heroes, and I couldn’t be happier with the entire experience. From the initial consultation to the final installation, their team was professional, knowledgeable, and courteous.
Justin, the owner, took the time to answer all my questions and made sure I understood my options without any pressure. The installation was completed on schedule, and they left everything clean and tidy—no mess left behind. The new unit is working perfectly, and I can already feel the difference.
It's rare these days to find a company that combines technical skill with such great customer service at a reasonable price. I highly recommend Service Heroes to anyone in need of HVAC work. Thanks Justin, John and Joe for a job well done!
