Owner & Operator

Hi, I'm Mark Ortiz, the owner and operator of Collins Heating & Cooling.

I have built my business on a foundation of high-quality, honest, and reliable service. When you call Collins Heating & Cooling, you will be speaking directly to me. No matter if you're a home owner or business owner, I believe that when you invest in a new AC or furnace unit, you are not only investing in the equipment but also the company that provides that service. I take that trust my customers place in me seriously.

That commitment to my customers has paid off. While many businesses folded or saw big losses during the economic downturn, Collins Heating & Cooling has never had a down year. This is because of the focus on our customers and the faith that people have put in our business.

Call me anytime (219) 924-7423 for your heating or cooling needs.

Air Conditioning Maintenance

At Collins Heating & Cooling it's our goal to always keep our customers cool and comfortable during the hot summer season. The benefits of having us give your AC unit a detailed inspection and tune up are clear.

✓ Improved Comfort: Dirt, dust and debris build up can cause your indoor air to become stagnant and cause higher humidity making it feel muggy and uncomfortable.

✓ Prevent Costly Repairs: Over 70% of AC unit failures are due to very little, improper, or no maintenance. Routine maintenance catches small problems before they turn into expensive repairs.

✓ Lower Energy Costs: A detailed cleaning of your units coils, motor and other components removes built up dirt and debris which helps your system run at peak efficiency. When you air conditioner is running at it's best it does not have to cycle as often and takes less energy to keep you cool and comfortable which saves you money on your monthly utility bill.

On those days your AC unit is working it's hardest and that is when most failures happen. Give us a call and let us make sure this does not happen to you and your family this summer.

✓ Longer Equipment Life: When you have your air conditioning unit regularly serviced it will not need to work as hard and often to keep your home cool. This puts less wear and tear on your equipment which leads to a longer life. Saving you from an early investment in a new system.

Single Stage Armstrong Air Conditioners

Helping create your environment, your way.

We recognize that buying a new cooling system is a big decision. Having all the facts, and some professional advice, can help you select the system best suited for your home and your family’s needs. When selecting a unit, it’s important to remember that everyone’s needs are different. What’s most important to you and your family? Here are a few things to consider:

It’s pretty simple. A high-efficiency system helps lower your monthly utility bills. Efficiency is measured in SEER (Seasonal Energy Efficiency Ratio) and the higher the number, the greater the efficiency. Replacing an older unit with a 14 SEER or higher unit can increase performance and start saving you money immediately.

You can always count on your Armstrong Air unit. Innovations such as our MHT™ Technology and other advanced-design features work together to deliver premium performance and extend the life of your air conditioner.

Air Quality
Where you live matters. Your family’s sensitivity to a host of natural and man-made allergens means enhanced air quality is all the more critical in your home. And don’t forget humidity levels when you’re considering the ideal system for year-round comfort.

Peace of Mind
More control over your comfort—that’s our commitment to you. You can see it in our craftsmanship and innovation—like
our proprietary Comfort Sync™ controls, which allow you to easily monitor your unit’s performance and enjoy maximum comfort in your home.

Noise Reduction
Comfort and performance also include quiet operation of your system. Enjoy reduced operating noise with select models featuring a high-quality sound blanket for noise reduction

Give us a call today @ (219) 924-7423 for a free estimate and consultation on what system is best for your home or business.

I appreciated the prompt reply. Very nice job done. Mom is toastie. Very friendly will call again if we ever need work done. Will call Collins. Thank you for a job well done.☺

I feel the service provided by Mark exceeded expectations. He really went above and beyond to service my furnace as promptly as possible

Honest, Trustworthy and Professional service! I highly recommend Mark for any of your HVAC issues. You won't regret it! He brings that old fashioned feel to his service that is very hard to find these days. He explained everything regarding my home heating issues, in detail and he made me feel safe. If you have been looking for quality, honesty and great customer service....choose Collins! Very reasonable too!

My heat went out on the coldest day of the year, I called several HVAC companies and Collins was the first back to me. Mark came out and fixed the problem right away and was very kind and explained everything to me. As far as the price, let me just say he saved Christmas for my family this year!!!

Very pleased. They were able to come sooner than other places I called, and arrived within the window of time promised. Friendly and knowledgeable. I was fortunate that I only needed an inexpensive part, and felt they were very honest. I will use them again if I have problems in the future, and would

Mark was very professional and knowledgeable. He explained both the short term and long term fixes for our 21 year old furnace, without trying to sell us anything additional. We opted for a short term fix, and the repairs were done quickly and efficiently. I would highly recommend him to my friends.

Very satisfied customer here. Mark made us feel like we'd been friends for years. He's knowledgeable and provided excellent quality service. I highly recommend this company. I will continue to use them for any heating/cooling needs.

Our 30 year old furnace died on a cold Sunday morning. Collins answered our call on the first ring, came out promptly, got the furnace working again while we contemplated replacing it. When the furnace died again later that day, Collins came back with space heaters to borrow. We greatly appreciated the prompt and friendly service. We had a new furnace in two days.

Mark came out to figure out what was wrong with my furnace after I gave up trying to fix it myself. Glad to say after I now have heat. He was very quick to come out and explained the issue to me in detail and answered my questions(I'm kind of a techie so I like to understand how stuff works). He was affordable and a nice guy. Will definitely call him again if I have issues.

Quick. Very professional and reasonable pricing. I have had many contractors out at the house for our remodel and Collins was one of the few I actually felt comfortable and could trust. I thought I would need 2 new furnace units and he fixed them within the hour! Thank you!

Our furnace was acting up, or so we thought it was the furnace, and looked on this site to find a repair company. We (family, parents) have been burned before with bogus repairs, cleanings, unneeded sensors and didn't know who to trust. Collins H & C is a company we will deal with from now on. He answered promptly and came out the same day within 2 hours. He went down and looked at the furnace. Within 10 minutes Mark knew exactly what was wrong. He didn't try to up sell a cleaning or sensors. It was our thermostat. We were still "old school" with a 20 year old dial one. He replaced our dial with a digital one. He explained why the dials are not that great, that we were paying more to Nipsco, etc and how this new one will work. Excellent company. Highly, highly recommend.

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.

Mark helped with my parents heat. It just stopped working one night and they panicked because it was cold. But,I called Mark and Mark came out right away and took care the problem quickly. Can't recommend him enough. Thanks Mark!

Ive dealt with several guys who were suppose to be professionals at heating and cooling and not one of them knew what they were doing until i met mark. Hes so honest and trust worthy and wont quit until the problem is resolved. I highly recommend collins heating and cooling to anyone. I was so blessed when i met mark. He is the best there is and i have dealt with so many dishonest people. I can guarantee u wont be dissatified. I rate mark a ten. Love his bussiness.
