Fullerton Local HVAC Contractor


Would Recommend Them Without Hesitation

The entire process from initial inspection through installation and balancing was excellent. The team at AC Cool was thorough and professional. They worked with existing elements of my HVAC system where possible and upgraded replaced what was necessary to provide my family with a fantastic, affordable air conditioning system.

I couldn't be happier and would recommend them without hesitation to anyone who asks.

Katie answered our call with a smile (you could tell) and was able to help us out during this heat wave. She said they were running a special emergency on call service and they could get us in! Paul arrived the next day was quick and got the job done! Paul was very informative and helpful. We would definitely use AC Cool again.. (hopefully we do t need them anytime soon , though). But if we did they would be the first company we call!
