Jeremy with 4C is extremely professional and responsive. He assisted with my two A/C units that stopped working completely. I called at 7:30am and Jeremy was here at 8:30am. I’d recommend them to anyone in need of A/C work. I’ll definitely use them in the future!

Chris Rannigan was the most honest and trustworthy AC company I spoke to and I met with a total of four! He was also the most accommodating with my school schedule! I highly recommend him! Love supporting our Katy local businesses too!

Chris and his team answered quickly - even rescheduling per my meetings. Jeremy came out and cleaned out the drain line quickly. He also checked charge on both of the units.
Would def recommend them for their HVAC needs.

MY AC went out and not cooling this week as the temperature was soaring. A dear friend referred me to Chris, owner of 4C AC & Heating. He personally came out the same day and diagnosed immediately. My motor had blown out. We waited for the part (thank you COVID) and he installed it first thing the following morning. His wife Christina runs the office and absolutely so sweet. Such a humble, kind company to work with. This company is absolutely amazing! They're honest, professional and incredibly dedicated to excellence. The five stars says "Great." I would say "Exceptional." And learn one thing

I have to say that Chris and Cristina are the most humble and incredibly dedicated couple of people that I have come across when it comes to local business owners. giving that 100% customer service and feeling that I know I'm not being taken advantage of due to the lack of knowledgeable on my part on this line of business makes for a referral any day! You Guys are an A in my book. Connie Lujan-Flores

Chris and his friend did a great job on installing a new vent and so forth so that our patients are now able to be cooler. He showed up early for the job. They were in and out in less than 1.5 hours. He also charged less than what we were previously quoted by a different company. Thanks Chris!!!

Not very impressed at all with the service. The price I paid was not at par with the service i received. I will stick with more reputable company's so I get a warranty with the work done. He seemed to be in a hurry the whole time he was there and did not even check any part of the system. All he did was pump Freon and tell me i needed a new coil. I would have at least liked him to check the system out to be sure.

Gotta give them a 5star. A/c was down and everyone I called wanted to charge an arm and a leg. One even told me I needed a new unit. Chris came out same day on short notice and within 30min he had it working. Turns out I didn't need a new unit. It was a capacitor. Honesty goes a long way especially when having to survive in houstons heat. Thanks Chris for saving me from the sauna of a home
