Highland Indiana’s Heating And Cooling Company

Mark is unquestionably the most dependable and honest business owner out there. When he says he will be there at a certain time, he is. Once he starts the job, he stays on it till completion. And you will always get a very fair price and a guarantee. A business owner is only as good as his word and Mark's is as good as gold. Pleasure to work with someone who is so honest and caring.

I feel immensely grateful to have Mark Ortiz with Collins Heating & Cooling servicing my area. As a new homeowner, I've encountered a couple of issues over the past few months, and I sincerely don't know what I would have done without him. Recently, my A/C unit was not functioning properly, and I was immediately calmed by Mark’s quick follow-up, professionalism, very reasonable prices, and his ability to simply "get the job done". OUTSTANDING company and customer service. Thank you, for everything.

Mark came on time and he explained everything he did he did the best job ever and I truly appreciate him. He was extremely professional and I trusted his word. And his prices are very reasonable and fair. And he taught me a thing or two about my air conditioning system. I am always afraid to have service man come to the house but I truly felt safe with him. I will definitely be calling for his service again and recommending him to my other coworkers friends and neighbors.

Excellent customer service and very professional honest company! Came out to install our new furnace after we discovered a gas leak on our very old furnace, it needed to be replaced and he recommend a great solid product and was very prompt and courteous. Mark is phenomenal he lent us radiant space heaters in the meantime to help keep the house warm.
