Serving Greater Omaha & Western Iowa Since 1970

Always On Time... Or You Don't Pay A Dime!

McCarthy's Heating & Air Conditioning was started back in 1970 when John McCarthy Sr. was asked to put a used part on a system, and charge the customer as if the part was new. That was not the type of business Sr. wanted to work for, so he quit on the spot! When he got home, it didn't take him long to realized what he had just done - quit the only job that supported his wife and newborn son. His mother-in-law looked at him and said, "You're a smart man John, start your own business!" McCarthy's Heating & Air Conditioning opened shortly after that with just one man and one truck. In 1973, his wife, Mary Kay, also started working for the business full time, and it has been a family business ever since. Both Sr. and Mary Kay are both still involved in the day-to-day operations 45 years later.

Frank went further in his cleaning parts than any other person that has been here and we appreciate it very much If someone is getting paid anyway why not do the small things that make a difference anyway. That is what sets the higher standards and quality the way it should be but so often anymore is not .Big thank you to Frank

Highly recommend. Stumbled across this business when I needed an A/C repair a few years ago and I am so glad I found them! Consistently great service all the way around, with reasonable pricing. Very prompt. We especially appreciate Frank's work and advice. Will continue to use them.

Bought a condo 2 years ago. The furnace i thought was inspected? Had the furnace checked by, McCarthys before the winter at the end of October. Found out only 1 out of 2 coils were working, had exposed wiring also, however it did run, but may go out at anytime and didn't want to chance waiting til it's 10 below zero. Went over options with Tech & Adviser, who are very explanatory. Went with a heat pump and had installed..I would recommend them to anyone needing service with furnace or AC. They are very professional, friendly, polite and seems concerned about your comfort and experience with them and will work around some variables if needed. This goes down from John McCarthy , I met, to the people answering phones... Also had a small Glich afterwards, but quickly looked at and fixed. Very easy company to work with so far. Look forward to my continued Comfort with my club membership.

John, the owner of this company truly cares about people and wants to help people out. If integrity and good old fashion midwestern values are important to you, I would highly recommend using this company. If you are not happy with your service, John is will make it right.

McCarthy's has always been professional, on time and very knowledgeable about their products and services. We had them work on both our air conditioning issues and heating issues this year and they answered any and all questions we had and did not complete the job until we were completely satisfied. Brent and Grant are wonderful technicians and worked diligently to help us with our heating issues until the problem was solved. We highly recommend them and will be using them again in the future for all our HVAC needs! I have interacted with Elizabeth on the phone several times and she is very kind, attentive and caring. She makes sure the call gets routed to the right people and that issues are resolved in a timely and efficient manner. Thanks, McCarthy's!

I'm very thankful I found McCarthy's. I've only been a homeowner for about 5 years and haven't ran into furnace issues until this week. Of course it didn't happen when we had 50 some degree weather, it had to happen when it was 12 degrees out. The gentleman that was sent out was so professional and kind he was easy to talk to and actually kind of felt like a friend I was comfortable just hanging around and watching him work and him showing me step by step what he was doing. It was a great experience and even though it was a little costly it was well worth it because of the service he provided. Hopefully he will hear this because he is the reason why I look forward to doing business with you again.
