About 4C A/C & Heating, LLC
Chris and Christina Rannigan founded 4C A/C & Heating in July 2012. 4C A/C & Heating was named after the Rannigan family, Chris, Christina, Cailyn, and Cambrie. Chris has been in the industry since 2000 starting out his career as an installer and then a service technician before starting the company in 2012. He realized how important it is for homeowners to find an honest and trustworthy technician in their home and wanted to create a company where we would be trusted and represent the values we believe in.
We take pride in serving our community and our name/brand means alot to us. Christina’s background is in Human Resources and Health & Safety. She makes sure the day to day operations are running legally and safely. 🙂 She takes a lot of pride in every single person hired on the team and ensures every individual’s values align with the companys.

What Your Neighbors Say About Us
Amazing service! Chris and his team are absolutely amazing. They are prompt, thorough, kind, and just all around awesome. I have had many others come and look at our AC issues, and honestly I will never go anywhere else again. Their pricing is great and the work they do is even better...
Highly recommend. Our heat went out during a really cold day and Texans cannot do cold weather! Agent who answered my call was very helpful, transparent, and was able to get us a same day appointment. We had a technician here within 45 minutes of my call. Technician was done...
Saw the truck across the street at a neighbors. Called and Jeremy was awesome. He came assessed the problem, (compresser issue) had the part we needed in his truck and explained that he was able to get our air back in running in no time. Very awesome customer service...
Chris came out to inspect and quite repairs on my HVAC system the day after I called. He was on time and professional. He was able to come back later in the day to handle the actual repairs and had me up and running properly in no time. Highly recommend this company...
I have used this company in the past, they did great work and were extremely professional! I called them a second time for an unrelated issue, the technician informed me that he could not repair that coil because it was out of stock and wouldn't have one available for at least 6 months!...
