Jeremy was amazing! Honest, straightforward, respectful, and I didn't feel like I was being taken for a ride. The price he quoted for repairs I thought was reasonable, and it was much less than one of the other companies that came out provided. I truly feel like I am in good hands with 4C, and while I hope I don't have any issues for quite some time after this, I know who I'll be contacting when the time comes!

Excellent work and above and beyond service from 4C A/C & Heating! We found these guys last year after our old AC company couldn’t diagnose and fix a problem in our other house. We were so pleased we kept them when we moved to our new house and each time they come they impress us so much with their professionalism and their great customer service. Jeremy was our technician this time and he really went above and beyond with figuring out the issue and then doing maintenance. We got a chance to talk for a minute and he is such a neat person! I highly recommend 4C A/C & Heating!

We had another issue and Chris the owner came out to work on it. I called the office number Sunday afternoon and Chris said he would be out on Monday to assess the problem and fix it. He came as he said he would and took care of it and my AC is now working great! Thank you Chris and my wife and I are extremely satisfied with your service. We will use your company in the future for all of our HVAC needs and I have been singing your praise to my friends. I recommend your company to anybody who needs their AC worked on and who is looking for a honest tradesman.
